+
+Two-way channel extension for [pi](https://github.com/espennilsen/pi) — route messages between agents and Telegram, Slack, webhooks, or custom adapters.
+
+## Features
+
+- **Telegram adapter** — bidirectional via Bot API; polling, voice/audio transcription, `allowedChatIds` filtering
+- **Slack adapter** — bidirectional via Socket Mode + Web API
+- **Webhook adapter** — outgoing HTTP POST to any URL
+- **Chat bridge** — incoming messages are routed to the agent as prompts; responses sent back automatically; persistent (RPC) or stateless mode
+- **Event API** — `channel:send`, `channel:receive`, `channel:register` for inter-extension messaging
+- **Custom adapters** — register at runtime via `channel:register` event
+
+## Settings
+
+Add to `~/.pi/agent/settings.json` or `.pi/settings.json`:
+
+```json
+{
+  "pi-channels": {

+/**
+ * pi-channels — Built-in Slack adapter (bidirectional).
+ *
+ * Outgoing: Slack Web API chat.postMessage.
+ * Incoming: Socket Mode (WebSocket) for events + slash commands.
+ *
+ * Supports:
+ *   - Text messages (channels, groups, DMs, multi-party DMs)
+ *   - @mentions (app_mention events)
+ *   - Slash commands (/aivena by default)
+ *   - Typing indicators (chat action)
+ *   - Thread replies (when replying in threads)
+ *   - Message splitting for long messages (>3000 chars)
+ *   - Channel allowlisting (optional)
+ *
+ * Requires:
+ *   - App-level token (xapp-...) for Socket Mode — in settings under pi-channels.slack.appToken
+ *   - Bot token (xoxb-...) for Web API — in settings under pi-channels.slack.botToken
+ *   - Socket Mode enabled in app settings
+ *
+ * Config in ~/.pi/agent/settings.json:
+ * {
+ *   "pi-channels": {
+ *     "adapters": {
+ *       "slack": {

+ * pi-channels — Built-in Telegram adapter (bidirectional).
+ *
+ * Outgoing: Telegram Bot API sendMessage.
+ * Incoming: Long-polling via getUpdates.
+ *
+ * Supports:
+ *   - Text messages
+ *   - Photos (downloaded → temp file → passed as image attachment)
+ *   - Documents (text files downloaded → content included in message)
+ *   - Voice messages (downloaded → transcribed → passed as text)
+ *   - Audio files (music/recordings → transcribed → passed as text)
+ *   - Audio documents (files with audio MIME → routed through transcription)
+ *   - File size validation (1MB for docs/photos, 10MB for voice/audio)
+ *   - MIME type filtering (text-like files only for documents)
+ *
+ * Config (in settings.json under pi-channels.adapters.telegram):
+ * {
+ *   "type": "telegram",
+ *   "botToken": "your-telegram-bot-token",
+ *   "parseMode": "Markdown",

+# pi-memory-md
+
+Letta-like memory management for [pi](https://github.com/badlogic/pi-mono) using GitHub-backed markdown files.
+
+## Features
+
+- **Persistent Memory**: Store context, preferences, and knowledge across sessions
+- **Git-backed**: Version control with full history
+- **Prompt append**: Memory index automatically appended to conversation at session start
+- **On-demand access**: LLM reads full content via tools when needed
+- **Multi-project**: Separate memory spaces per project
+
+## Quick Start
+
+```bash
+# 1. Install
+pi install npm:pi-memory-md
+# Or for latest from GitHub:
+pi install git:github.com/VandeeFeng/pi-memory-md
+
+# 2. Create a GitHub repository (private recommended)
+
+# 3. Configure pi
+# Add to ~/.pi/agent/settings.json:
+{
+  "pi-memory-md": {
+    "enabled": true,
+    "repoUrl": "git@github.com:username/repo.git",
+    "localPath": "~/.pi/memory-md"
+  }
+}
+
+# 4. Start a new pi session
+# The extension will auto-initialize and sync on first run
+```
+
+**Commands available in pi:**
+- `:memory-init` - Initialize repository structure
+- `:memory-status` - Show repository status
+
+## How It Works
+
+```
+Session Start
+    ↓
+1. Git pull (sync latest changes)
+    ↓
+2. Scan all .md files in memory directory
+    ↓
+3. Build index (descriptions + tags only - NOT full content)
+    ↓
+4. Append index to conversation via prompt append (not system prompt)
+    ↓
+5. LLM reads full file content via tools when needed
+```
+
+**Why index-only via prompt append?** Keeps token usage low while making full content accessible on-demand. The index is appended to the conversation, not injected into the system prompt.
+
+## Available Tools
+
+The LLM can use these tools to interact with memory:
+
+| Tool | Parameters | Description |
+|------|------------|-------------|
+| `memory_init` | `{force?: boolean}` | Initialize or reinitialize repository |
+| `memory_sync` | `{action: "pull" | "push" | "status"}` | Git operations |
+| `memory_read` | `{path: string}` | Read a memory file |
+| `memory_write` | `{path, content, description, tags?}` | Create/update memory file |
+| `memory_list` | `{directory?: string}` | List all memory files |
+| `memory_search` | `{query, searchIn}` | Search by content/tags/description |
+
+## Memory File Format
+
+```markdown
+---
+description: "User identity and background"
+tags: ["user", "identity"]
+created: "2026-02-14"
+updated: "2026-02-14"
+---
+
+# Your Content Here
+
+Markdown content...
+```
+
+## Directory Structure
+
+```
+~/.pi/memory-md/
+└── project-name/
+    ├── core/
+    │   ├── user/           # Your preferences
+    │   │   ├── identity.md
+    │   │   └── prefer.md
+    │   └── project/        # Project context
+    │       └── tech-stack.md
+    └── reference/          # On-demand docs
+```
+
+## Configuration
+
+```json
+{
+  "pi-memory-md": {
+    "enabled": true,
+    "repoUrl": "git@github.com:username/repo.git",
+    "localPath": "~/.pi/memory-md",
+    "injection": "message-append",
+    "autoSync": {
+      "onSessionStart": true
+    }
+  }
+}
+```
+
+| Setting | Default | Description |
+|---------|---------|-------------|
+| `enabled` | `true` | Enable extension |
+| `repoUrl` | Required | GitHub repository URL |
+| `localPath` | `~/.pi/memory-md` | Local clone path |
+| `injection` | `"message-append"` | Memory injection mode: `"message-append"` or `"system-prompt"` |
+| `autoSync.onSessionStart` | `true` | Git pull on session start |
+
+### Memory Injection Modes
+
+The extension supports two modes for injecting memory into the conversation:
+
+#### 1. Message Append (Default)
+
+```json
+{
+  "pi-memory-md": {
+    "injection": "message-append"
+  }
+}
+```
+
+- Memory is sent as a custom message before the user's first message
+- Not visible in the TUI (`display: false`)
+- Persists in the session history
+- Injected only once per session (on first agent turn)
+- **Pros**: Lower token usage, memory persists naturally in conversation
+- **Cons**: Only visible when the model scrolls back to earlier messages
+
+#### 2. System Prompt
+
+```json
+{
+  "pi-memory-md": {
+    "injection": "system-prompt"
+  }
+}
+```
+
+- Memory is appended to the system prompt
+- Rebuilt and injected on every agent turn
+- Always visible to the model in the system context
+- **Pros**: Memory always present in system context, no need to scroll back
+- **Cons**: Higher token usage (repeated on every prompt)
+
+**Recommendation**: Use `message-append` (default) for optimal token efficiency. Switch to `system-prompt` if you notice the model not accessing memory consistently.
+
+## Usage Examples
+
+Simply talk to pi - the LLM will automatically use memory tools when appropriate:
+
+```
+You: Save my preference for 2-space indentation in TypeScript files to memory.
+
+Pi: [Uses memory_write tool to save your preference]
+```
+
+You can also explicitly request operations:
+
+```
+You: List all memory files for this project.
+You: Search memory for "typescript" preferences.
+You: Read core/user/identity.md
+You: Sync my changes to the repository.
+```
+
+The LLM automatically:
+- Reads memory index at session start (appended to conversation)
+- Writes new information when you ask to remember something
+- Syncs changes when needed
+
+## Commands
+
+Use these directly in pi:
+
+- `:memory-status` - Show repository status
+- `:memory-init` - Initialize repository structure

+---
+
+# Memory Init
+
+Use this skill to set up pi-memory-md for the first time or reinitialize an existing installation.
+
+## Prerequisites
+
+1. **GitHub repository** - Create a new empty repository on GitHub
+2. **Git access** - Configure SSH keys or personal access token
+3. **Node.js & npm** - For installing the package
+
+## Step 1: Install Package
+
+```bash
+pi install npm:pi-memory-md
+```
+
+## Step 2: Create GitHub Repository
+
+Create a new repository on GitHub:
+- Name it something like `memory-md` or `pi-memory`
+- Make it private (recommended)
+- Don't initialize with README (we'll do that)
+
+**Clone URL will be:** `git@github.com:username/repo-name.git`
+
+## Step 3: Configure Settings
+
+Add to your settings file (global: `~/.pi/agent/settings.json`, project: `.pi/settings.json`):
+
+```json
+{
+  "pi-memory-md": {
+    "enabled": true,
+    "repoUrl": "git@github.com:username/repo-name.git",
+    "localPath": "~/.pi/memory-md",
+    "autoSync": {
+      "onSessionStart": true
+    }
+  }
+}
+```
+
+**Settings explained:**
+
+| Setting | Purpose | Default |
+|---------|---------|----------|
+| `enabled` | Enable/disable extension | `true` |
+| `repoUrl` | GitHub repository URL | Required |
+| `localPath` | Local clone location (supports `~`) | `~/.pi/memory-md` |
+| `autoSync.onSessionStart` | Auto-pull on session start | `true` |
+
+## Step 4: Initialize Repository
+
+Start pi and run:
+
+```
+memory_init()
+```
+
+**This does:**
+1. Clones the GitHub repository
+2. Creates directory structure:
+   - `core/user/` - Your identity and preferences
+   - `core/project/` - Project-specific info
+3. Creates default files:
+   - `core/user/identity.md` - User identity template
+   - `core/user/prefer.md` - User preferences template
+
+**Example output:**
+```
+Memory repository initialized:
+Cloned repository successfully
+
+Created directory structure:
+  - core/user
+  - core/project
+  - reference
+```
+
+## Step 5: Import Preferences from AGENTS.md
+
+After initialization, extract relevant preferences from your `AGENTS.md` file to populate `prefer.md`:
+
+1. **Read AGENTS.md** (typically at `.pi/agent/AGENTS.md` or project root)
+
+2. **Extract relevant sections** such as:
+   - IMPORTANT Rules
+   - Code Quality Principles
+   - Coding Style Preferences
+   - Architecture Principles
+   - Development Workflow
+   - Technical Preferences
+
+3. **Present extracted content** to the user in a summarized format
+
+4. **Ask first confirmation**: Include these extracted preferences in `prefer.md`?
+   ```
+   Found these preferences in AGENTS.md:
+   - IMPORTANT Rules: [summary]
+   - Code Quality Principles: [summary]
+   - Coding Style: [summary]
+
+   Include these in core/user/prefer.md? (yes/no)
+   ```
+
+5. **Ask for additional content**: Is there anything else you want to add to your preferences?
+   ```
+   Any additional preferences you'd like to include? (e.g., communication style, specific tools, workflows)
+   ```
+
+6. **Update prefer.md** with:
+   - Extracted content from AGENTS.md (if user confirmed)
+   - Any additional preferences provided by user
+
+## Step 6: Verify Setup
+
+Check status with command:
+
+```
+/memory-status
+```
+
+Should show: `Memory: project-name | Repo: Clean | Path: {localPath}/project-name`
+
+List files:
+
+```
+memory_list()
+```
+
+Should show: `core/user/identity.md`, `core/user/prefer.md`
+
+## Project Structure
+
+**Base path**: Configured via `settings["pi-memory-md"].localPath` (default: `~/.pi/memory-md`)
+
+Each project gets its own folder in the repository:
+
+```
+{localPath}/
+├── project-a/
+│   ├── core/
+│   │   ├── user/
+│   │   │   ├── identity.md
+│   │   │   └── prefer.md
+│   │   └── project/
+│   └── reference/
+├── project-b/
+│   └── ...
+└── project-c/
+    └── ...
+```
+
+Project name is derived from:
+- Git repository name (if in a git repo)
+- Or current directory name
+
+## First-Time Setup Script
+
+Automate setup with this script:
+
+```bash
+#!/bin/bash
+# setup-memory-md.sh
+
+REPO_URL="git@github.com:username/memory-repo.git"
+SETTINGS_FILE="$HOME/.pi/agent/settings.json"
+
+# Backup existing settings
+cp "$SETTINGS_FILE" "$SETTINGS_FILE.bak"
+
+# Add pi-memory-md configuration
+node -e "
+const fs = require('fs');
+const path = require('path');
+const settingsPath = '$SETTINGS_FILE';
+const settings = JSON.parse(fs.readFileSync(settingsPath, 'utf8'));
+settings['pi-memory-md'] = {
+  enabled: true,
+  repoUrl: '$REPO_URL',
+  localPath: path.join(require('os').homedir(), '.pi', 'memory-md'),
+  autoSync: {
+    onSessionStart: true,
+    onMessageCreate: false
+  }
+};
+fs.writeFileSync(settingsPath, JSON.stringify(settings, null, 2));
+"
+
+echo "Settings configured. Now run: memory_init()"
+```
+
+## Reinitializing
+
+To reset everything:
+
+```
+memory_init(force=true)
+```
+
+**Warning:** This will re-clone the repository, potentially losing local uncommitted changes.
+
+## Troubleshooting
+
+### Clone Failed
+
+**Error:** `Clone failed: Permission denied`
+
+**Solution:**
+1. Verify SSH keys are configured: `ssh -T git@github.com`
+2. Check repo URL is correct in settings
+3. Ensure repo exists on GitHub
+
+### Settings Not Found
+
+**Error:** `GitHub repo URL not configured in settings["pi-memory-md"].repoUrl`
+
+**Solution:**
+1. Edit settings file (global or project)
+2. Add `pi-memory-md` section (see Step 3)
+3. Run `/reload` in pi
+
+### Directory Already Exists
+
+**Error:** `Directory exists but is not a git repo`
+
+**Solution:**
+1. Remove existing directory: `rm -rf {localPath}` (use your configured path)
+2. Run `memory_init()` again
+
+### No Write Permission
+
+**Error:** `EACCES: permission denied`
+
+**Solution:**
+1. Check directory permissions: `ls -la {localPath}/..` (use your configured path)
+2. Fix ownership: `sudo chown -R $USER:$USER {localPath}` (use your configured path)
+
+## Verification Checklist
+
+After setup, verify:
+
+- [ ] Package installed: `pi install npm:pi-memory-md`
+- [ ] Settings configured in settings file
+- [ ] GitHub repository exists and is accessible
+- [ ] Repository cloned to configured `localPath`
+- [ ] Directory structure created
+- [ ] `/memory-status` shows correct info
+- [ ] `memory_list()` returns files
+- [ ] `prefer.md` populated (either from AGENTS.md or default template)
+
+## Next Steps
+
+After initialization:
+
+1. **Import preferences** - Agent will prompt to extract from AGENTS.md
+2. Edit your identity: `memory_read(path="core/user/identity.md")` then `memory_write(...)` to update
+3. Review preferences: `memory_read(path="core/user/prefer.md")`
+4. Add project context: `memory_write(path="core/project/overview.md", ...)`
+5. Learn more: See `memory-management` skill

+
+# Memory Management
+
+Use this skill when working with pi-memory-md memory files. Memory is stored as markdown files with YAML frontmatter in a git repository.
+
+## Design Philosophy
+
+Inspired by Letta memory filesystem:
+
+- **File-based memory**: Each memory is a `.md` file with YAML frontmatter
+- **Git-backed**: Full version control and cross-device sync
+- **Auto-injection**: Files in `core/` are automatically injected to context
+- **Organized by purpose**: Fixed structure for core info, flexible for everything else
+
+## Directory Structure
+
+**Base path**: Configured via `settings["pi-memory-md"].localPath` (default: `~/.pi/memory-md`)
+
+```
+{localPath}/
+└── {project-name}/                  # Project memory root
+    ├── core/                        # Auto-injected to context every session
+    │   ├── user/                    # 【FIXED】User information
+    │   │   ├── identity.md          # Who the user is
+    │   │   └── prefer.md            # User habits and code style preferences
+    │   │
+    │   └── project/                 # 【FIXED】Project information (pre-created)
+    │       ├── overview.md          # Project overview
+    │       ├── architecture.md      # Architecture and design
+    │       ├── conventions.md       # Code conventions
+    │       └── commands.md          # Common commands
+    │
+    ├── docs/                        # 【AGENT-CREATED】Reference documentation
+    ├── archive/                     # 【AGENT-CREATED】Historical information
+    ├── research/                    # 【AGENT-CREATED】Research findings
+    └── notes/                       # 【AGENT-CREATED】Standalone notes
+```
+
+**Important:** `core/project/` is a pre-defined folder under `core/`. Do NOT create another `project/` folder at the project root level.
+
+## Core Design: Fixed vs Flexible
+
+### 【FIXED】core/user/ and core/project/
+
+These are **pre-defined** and **auto-injected** into every session:
+
+**core/user/** - User information (2 fixed files)
+- `identity.md` - Who the user is (name, role, background)
+- `prefer.md` - User habits and code style preferences
+
+**core/project/** - Project information
+- `overview.md` - Project overview
+- `architecture.md` - Architecture and design
+- `conventions.md` - Code conventions
+- `commands.md` - Common commands
+- `changelog.md` - Development history
+
+**Why fixed?**
+- Always in context, no need to remember to load
+- Core identity that defines every interaction
+- Project context needed for all decisions
+
+**Rule:** ONLY `user/` and `project/` exist under `core/`. No other folders.
+
+## Decision Tree
+
+### Does this need to be in EVERY conversation?
+
+**Yes** → Place under `core/`
+- User-related → `core/user/`
+- Project-related → `core/project/`
+
+**No** → Place at project root level (same level as `core/`)
+- Reference docs → `docs/`
+- Historical → `archive/`
+- Research → `research/`
+- Notes → `notes/`
+- Other? → Create appropriate folder
+
+**Important:** `core/project/` is a FIXED subdirectory under `core/`. Always use `core/project/` for project-specific memory files, NEVER create a `project/` folder at the root level.
+
+## YAML Frontmatter Schema
+
+Every memory file MUST have YAML frontmatter:
+
+```yaml
+---
+description: "Human-readable description of this memory file"
+tags: ["user", "identity"]
+created: "2026-02-14"
+updated: "2026-02-14"
+---
+```
+
+**Required fields:**
+- `description` (string) - Human-readable description
+
+**Optional fields:**
+- `tags` (array of strings) - For searching and categorization
+- `created` (date) - File creation date (auto-added on create)
+- `updated` (date) - Last modification date (auto-updated on update)
+
+## Examples
+
+### Example 1: User Identity (core/user/identity.md)
+
+```bash
+memory_write(
+  path="core/user/identity.md",
+  description="User identity and background",
+  tags=["user", "identity"],
+  content="# User Identity\n\nName: Vandee\nRole: Developer..."
+)
+```
+
+### Example 2: User Preferences (core/user/prefer.md)
+
+```bash
+memory_write(
+  path="core/user/prefer.md",
+  description="User habits and code style preferences",
+  tags=["user", "preferences"],
+  content="# User Preferences\n\n## Communication Style\n- Be concise\n- Show code examples\n\n## Code Style\n- 2 space indentation\n- Prefer const over var\n- Functional programming"
+)
+```
+
+### Example 3: Project Architecture (core/project/)
+
+```bash
+memory_write(
+  path="core/project/architecture.md",
+  description="Project architecture and design",
+  tags=["project", "architecture"],
+  content="# Architecture\n\n..."
+)
+```
+
+### Example 3: Reference Docs (root level)
+
+```bash
+memory_write(
+  path="docs/api/rest-endpoints.md",
+  description="REST API reference documentation",
+  tags=["docs", "api"],
+  content="# REST Endpoints\n\n..."
+)
+```
+
+### Example 4: Archived Decision (root level)
+
+```bash
+memory_write(
+  path="archive/decisions/2024-01-15-auth-redesign.md",
+  description="Auth redesign decision from January 2024",
+  tags=["archive", "decision"],
+  content="# Auth Redesign\n\n..."
+)
+```
+
+## Reading Memory Files
+
+Use the `memory_read` tool:
+
+```bash
+memory_read(path="core/user/identity.md")
+```
+
+## Listing Memory Files
+
+Use the `memory_list` tool:
+
+```bash
+# List all files
+memory_list()
+
+# List files in specific directory
+memory_list(directory="core/project")
+
+# List only core/ files
+memory_list(directory="system")
+```
+
+## Updating Memory Files
+
+To update a file, use `memory_write` with the same path:
+
+```bash
+memory_write(
+  path="core/user/identity.md",
+  description="Updated user identity",
+  content="New content..."
+)
+```
+
+The extension preserves existing `created` date and updates `updated` automatically.
+
+## Folder Creation Guidelines
+
+### core/ directory - FIXED structure
+
+**Only two folders exist under `core/`:**
+- `user/` - User identity and preferences
+- `project/` - Project-specific information
+
+**Do NOT create any other folders under `core/`.**
+
+### Root level (same level as core/) - COMPLETE freedom
+
+**Agent can create any folder structure at project root level (same level as `core/`):**
+
+- `docs/` - Reference documentation
+- `archive/` - Historical information
+- `research/` - Research findings
+- `notes/` - Standalone notes
+- `examples/` - Code examples
+- `guides/` - How-to guides
+
+**Rule:** Organize root level in a way that makes sense for the project.
+
+**WARNING:** Do NOT create a `project/` folder at root level. Use `core/project/` instead.
+
+## Best Practices
+
+### DO:
+- Use `core/user/identity.md` for user identity
+- Use `core/user/prefer.md` for user habits and code style
+- Use `core/project/` for project-specific information
+- Use root level for reference, historical, and research content
+- Keep files focused on a single topic
+- Organize root level folders by content type
+
+### DON'T:
+- Create folders under `core/` other than `user/` and `project/`
+- Create other files under `core/user/` (only `identity.md` and `prefer.md`)
+- Create a `project/` folder at root level (use `core/project/` instead)
+- Put reference docs in `core/` (use root `docs/`)
+- Create giant files (split into focused topics)
+- Mix unrelated content in same file
+

+
+After completing work, archive to root level:
+
+```bash
+memory_write(
+  path="archive/sessions/2025-02-14-bug-fix.md",
+  description="Session summary: fixed database connection bug",
+  tags=["archive", "session"],
+  content="..."
+)
+```
+
+### Regular Cleanup
+
+- Consolidate duplicate information
+- Update descriptions to stay accurate
+- Remove information that's no longer relevant
+- Archive old content to appropriate root level folders
+
+## When to Use This Skill
+
+Use `memory-management` when:
+- User asks to remember something for future sessions
+- Creating or updating project documentation
+- Setting preferences or guidelines
+- Storing reference material
+- Building knowledge base about the project
+- Organizing information by type or domain
+- Creating reusable patterns and solutions
+- Documenting troubleshooting steps
+
+## Related Skills
+
+- `memory-sync` - Git synchronization operations
+- `memory-init` - Initial repository setup
+- `memory-search` - Finding specific information
+- `memory-check` - Validate folder structure before syncing
+
+## Before Syncing
+
+**IMPORTANT**: Before running `memory_sync(action="push")`, ALWAYS run `memory_check()` first to verify the folder structure is correct:
+
+```bash
+# Check structure first
+memory_check()
+
+# Then push if structure is correct
+memory_sync(action="push")
+```
+
+This prevents accidentally pushing files in wrong locations (e.g., root `project/` instead of `core/project/`).

+
+# Memory Search
+
+Use this skill to find information stored in pi-memory-md memory files.
+
+## Search Types
+
+### Search by Content
+
+Search within markdown content:
+
+```
+memory_search(query="typescript", searchIn="content")
+```
+
+Returns matching files with content excerpts.
+
+### Search by Tags
+
+Find files with specific tags:
+
+```
+memory_search(query="user", searchIn="tags")
+```
+
+Best for finding files by category or topic.
+
+### Search by Description
+
+Find files by their frontmatter description:
+
+```
+memory_search(query="identity", searchIn="description")
+```
+
+Best for discovering files by purpose.
+
+## Common Search Patterns
+
+| Goal | Command |
+|------|---------|
+| User preferences | `memory_search(query="user", searchIn="tags")` |
+| Project info | `memory_search(query="architecture", searchIn="description")` |
+| Code style | `memory_search(query="typescript", searchIn="content")` |
+| Reference docs | `memory_search(query="reference", searchIn="tags")` |
+
+## Search Tips
+
+- **Case insensitive**: `typescript` and `TYPESCRIPT` work the same
+- **Partial matches**: `auth` matches "auth", "authentication", "author"
+- **Be specific**: "JWT token validation" > "token"
+- **Try different types**: If content search fails, try tags or description
+
+## When Results Are Empty
+
+1. Check query spelling
+2. Try different `searchIn` type
+3. List all files: `memory_list()`
+4. Sync repository: `memory_sync(action="pull")`

+# Memory Sync
+
+Git synchronization for pi-memory-md repository.
+
+## Configuration
+
+Configure `pi-memory-md.repoUrl` in settings file (global: `~/.pi/agent/settings.json`, project: `.pi/settings.json`)
+
+## Sync Operations
+
+### Pull
+
+Fetch latest changes from GitHub:
+
+```
+memory_sync(action="pull")
+```
+
+Use before starting work or switching machines.
+
+### Push
+
+Upload local changes to GitHub:
+
+```
+memory_sync(action="push")
+```
+
+Auto-commits changes before pushing.
+
+**Before pushing, ALWAYS run memory_check first:**
+
+```
+memory_check()
+```
+
+This verifies that the folder structure is correct (e.g., files are in `core/project/` not in a root `project/` folder).
+
+### Status
+
+Check uncommitted changes:
+
+```
+memory_sync(action="status")
+```
+
+Shows modified/added/deleted files.
+
+## Typical Workflow
+
+| Action | Command |
+|--------|---------|
+| Get updates | `memory_sync(action="pull")` |
+| Check changes | `memory_sync(action="status")` |
+| Upload changes | `memory_sync(action="push")` |
+
+## Troubleshooting
+
+| Error | Solution |
+|--------|----------|
+| Non-fast-forward | Pull first, then push |
+| Conflicts | Manual resolution via bash git commands |
+| Not a git repo | Run `memory_init(force=true)` |
+| Permission denied | Check SSH keys or repo URL |

+# pi-runtime-daemon
+
+Local runtime watchdog for keeping a Python runtime process running.
+
+This package intentionally stays local to the monorepo (`packages/pi-runtime-daemon`) so you can inspect and edit the code directly.
+
+## What this does
+
+- Runs a single command and restarts it on crash.
+- Verifies startup health before marking the process healthy.
+- Performs recurring health probes and restarts when they fail.
+- Writes a PID file.
+- Supports graceful shutdown and a small set of flags.
+
+## Usage
+
+```bash
+npx pi-runtime-daemon --command "python -m myruntime --serve"
+```
+
+```bash
+node ./bin/pi-runtime-daemon.mjs \
+  --command "python -m myruntime" \
+  --health-url "http://127.0.0.1:8765/health" \
+  --startup-timeout-ms 30000
+```
+
+## Options
+
+- `--command <string>` command run by the daemon (required).
+- `--health-url <url>` optional readiness probe URL.
+- `--health-cmd <shell command>` optional shell command probe.
+- `--startup-timeout-ms <ms>` default: `30000`.
+- `--probe-interval-ms <ms>` default: `5000`.
+- `--probe-timeout-ms <ms>` default: `2000`.
+- `--restart-delay-ms <ms>` default: `1000`.
+- `--graceful-stop-timeout-ms <ms>` default: `5000`.
+- `--pid-file <path>` optional pidfile path.
+- `--name <string>` display name in logs, default: `pi-runtime-daemon`.
+- `--env KEY=VALUE` optional repeated process env overrides.
+- `--help` prints usage.
+
+## Script integration
+
+From this repo run:
+
+```bash
+npm install
+npx pi-runtime-daemon --help
+```

+# pi-teams: Agent Guide 🤖
+
+This guide explains how `pi-teams` transforms your single Pi agent into a coordinated team of specialists. It covers the roles, capabilities, and coordination patterns available to you as the **Team Lead**.
+
+---
+
+## 🎭 The Two Roles
+
+In a `pi-teams` environment, there are two distinct types of agents:
+
+### 1. The Team Lead (You)
+The agent in your main terminal window. You are responsible for:
+- **Strategy**: Creating the team and defining its goals.
+- **Delegation**: Spawning teammates and assigning them specific roles.
+- **Coordination**: Managing the shared task board and broadcasting updates.
+- **Quality Control**: Reviewing plans and approving finished work.
+
+### 2. Teammates (The Specialists)
+Agents spawned in separate panes. They are designed for:
+- **Focus**: Executing specific, isolated tasks (e.g., "Security Audit", "Frontend Refactor").
+- **Parallelism**: Working on multiple parts of the project simultaneously.
+- **Autonomy**: Checking their own inboxes, submitting plans, and reporting progress without constant hand-holding.
+
+---
+
+## 🛠 Capabilities
+
+### 🚀 Specialist Spawning
+You can create teammates with custom identities, models, and reasoning depths:
+- **Custom Roles**: "Spawn a 'CSS Expert' to fix the layout shifts."
+- **Model Selection**: Use `gpt-4o` for complex architecture and `haiku` for fast, repetitive tasks.
+- **Thinking Levels**: Set thinking to `high` for deep reasoning or `off` for maximum speed.
+
+### 📋 Shared Task Board
+A centralized source of truth for the entire team:
+- **Visibility**: Everyone can see the full task list and who owns what.
+- **Status Tracking**: Tasks move through `pending` ➔ `planning` ➔ `in_progress` ➔ `completed`.
+- **Ownership**: Assigning a task to a teammate automatically notifies them.
+
+### 💬 Coordination & Messaging
+Communication flows naturally between team members:
+- **Direct Messaging**: Send specific instructions to one teammate.
+- **Broadcasts**: Announce global changes (like API updates) to everyone at once.
+- **Inbox Polling**: Teammates automatically "wake up" to check for new work every 30 seconds when idle.
+
+### 🛡️ Plan Approval Mode
+For critical changes, you can require teammates to submit a plan before they start:
+1. Teammate analyzes the task and calls `task_submit_plan`.
+2. You review the plan in the Lead pane.
+3. You `approve` (to start work) or `reject` (with feedback for revision).
+
+---
+
+## 💡 Coordination Patterns
+
+### Pattern 1: The "Parallel Sprint"
+Use this when you have 3-4 independent features to build.
+1. Create a team: `team_create({ team_name: "feature-sprint" })`
+2. Spawn specialists for each feature.
+3. Create tasks for each specialist.
+4. Monitor progress while you work on the core architecture.
+
+### Pattern 2: The "Safety First" Audit
+Use this for refactoring or security work.
+1. Spawn a teammate with `plan_mode_required: true`.
+2. Assign the refactoring task.
+3. Review their proposed changes before any code is touched.
+4. Approve the plan to let them execute.
+
+### Pattern 3: The "Quality Gate"
+Use automated hooks to ensure standards.
+1. Define a script at `.pi/team-hooks/task_completed.sh`.
+2. When any teammate marks a task as `completed`, the hook runs (e.g., runs `npm test`).
+3. If the hook fails, you'll know the work isn't ready.
+
+---
+
+## 🛑 When to Use pi-teams
+- **Complex Projects**: Tasks that involve multiple files and logic layers.
+- **Research & Execution**: One agent researches while another implements.
+- **Parallel Testing**: Running different test suites in parallel.
+- **Code Review**: Having one agent write code and another (specialized) agent review it.
+
+## ⚠️ Best Practices
+- **Isolation**: Give teammates tasks that don't overlap too much to avoid git conflicts.
+- **Clear Prompts**: Be specific about the teammate's role and boundaries when spawning.
+- **Check-ins**: Use `task_list` regularly to see the "big picture" of your team's progress.

+# pi-teams 🚀
+
+**pi-teams** turns your single Pi agent into a coordinated software engineering team. It allows you to spawn multiple "Teammate" agents in separate terminal panes that work autonomously, communicate with each other, and manage a shared task board—all mediated through tmux, Zellij, iTerm2, or WezTerm.
+
+### 🖥️ pi-teams in Action
+
+| iTerm2 | tmux | Zellij |
+| :---: | :---: | :---: |
+| <a href="iTerm2.png"><img src="iTerm2.png" width="300" alt="pi-teams in iTerm2"></a> | <a href="tmux.png"><img src="tmux.png" width="300" alt="pi-teams in tmux"></a> | <a href="zellij.png"><img src="zellij.png" width="300" alt="pi-teams in Zellij"></a> |
+
+*Also works with **WezTerm** (cross-platform support)*
+
+## 🛠 Installation
+
+Open your Pi terminal and type:
+
+```bash
+pi install npm:pi-teams
+```
+
+## 🚀 Quick Start
+
+```bash
+# 1. Start a team (inside tmux, Zellij, or iTerm2)
+"Create a team named 'my-team' using 'gpt-4o'"
+
+# 2. Spawn teammates
+"Spawn 'security-bot' to scan for vulnerabilities"
+"Spawn 'frontend-dev' using 'haiku' for quick iterations"
+
+# 3. Create and assign tasks
+"Create a task for security-bot: 'Audit auth endpoints'"
+
+# 4. Review and approve work
+"List all tasks and approve any pending plans"
+```
+
+## 🌟 What can it do?
+
+### Core Features
+- **Spawn Specialists**: Create agents like "Security Expert" or "Frontend Pro" to handle sub-tasks in parallel.
+- **Shared Task Board**: Keep everyone on the same page with a persistent list of tasks and their status.
+- **Agent Messaging**: Agents can send direct messages to each other and to you (the Team Lead) to report progress.
+- **Autonomous Work**: Teammates automatically "wake up," read their instructions, and poll their inboxes for new work while idle.
+- **Beautiful UI**: Optimized vertical splits in `tmux` with clear labels so you always know who is doing what.
+
+### Advanced Features
+- **Isolated OS Windows**: Launch teammates in true separate OS windows instead of panes.
+- **Persistent Window Titles**: Windows are automatically titled `[team-name]: [agent-name]` for easy identification in your window manager.
+- **Plan Approval Mode**: Require teammates to submit their implementation plans for your approval before they touch any code.
+- **Broadcast Messaging**: Send a message to the entire team at once for global coordination and announcements.
+- **Quality Gate Hooks**: Automated shell scripts run when tasks are completed (e.g., to run tests or linting).
+- **Thinking Level Control**: Set per-teammate thinking levels (`off`, `minimal`, `low`, `medium`, `high`) to balance speed vs. reasoning depth.
+
+## 💬 Key Examples
+
+### 1. Start a Team
+> **You:** "Create a team named 'my-app-audit' for reviewing the codebase."
+
+**Set a default model for the whole team:**
+> **You:** "Create a team named 'Research' and use 'gpt-4o' for everyone."
+
+**Start a team in "Separate Windows" mode:**
+> **You:** "Create a team named 'Dev' and open everyone in separate windows."
+*(Supported in iTerm2 and WezTerm only)*
+
+### 2. Spawn Teammate with Custom Settings
+> **You:** "Spawn a teammate named 'security-bot' in the current folder. Tell them to scan for hardcoded API keys."
+
+**Spawn a specific teammate in a separate window:**
+> **You:** "Spawn 'researcher' in a separate window."
+
+**Move the Team Lead to a separate window:**
+> **You:** "Open the team lead in its own window."
+*(Requires separate_windows mode enabled or iTerm2/WezTerm)*
+
+**Use a different model:**
+> **You:** "Spawn a teammate named 'speed-bot' using 'haiku' to quickly run some benchmarks."
+
+**Require plan approval:**
+> **You:** "Spawn a teammate named 'refactor-bot' and require plan approval before they make any changes."
+
+**Customize model and thinking level:**
+> **You:** "Spawn a teammate named 'architect-bot' using 'gpt-4o' with 'high' thinking level for deep reasoning."
+
+**Smart Model Resolution:**
+When you specify a model name without a provider (e.g., `gemini-2.5-flash`), pi-teams automatically:
+- Queries available models from `pi --list-models`
+- Prioritizes **OAuth/subscription providers** (cheaper/free) over API-key providers:
+  - `google-gemini-cli` (OAuth) is preferred over `google` (API key)
+  - `github-copilot`, `kimi-sub` are preferred over their API-key equivalents
+- Falls back to API-key providers if OAuth providers aren't available
+- Constructs the correct `--model provider/model:thinking` command
+
+> **Example:** Specifying `gemini-2.5-flash` will automatically use `google-gemini-cli/gemini-2.5-flash` if available, saving API costs.
+
+### 3. Assign Task & Get Approval
+> **You:** "Create a task for security-bot: 'Check the .env.example file for sensitive defaults' and set it to in_progress."
+
+Teammates in `planning` mode will use `task_submit_plan`. As the lead, review their work:
+> **You:** "Review refactor-bot's plan for task 5. If it looks good, approve it. If not, reject it with feedback on the test coverage."
+
+### 4. Broadcast to Team
+> **You:** "Broadcast to the entire team: 'The API endpoint has changed to /v2. Please update your work accordingly.'"
+
+### 5. Shut Down Team
+> **You:** "We're done. Shut down the team and close the panes."

+
+## 🪟 Terminal Requirements
+
+To show multiple agents on one screen, **pi-teams** requires a way to manage terminal panes. It supports **tmux**, **Zellij**, **iTerm2**, and **WezTerm**.
+
+### Option 1: tmux (Recommended)
+
+Install tmux:
+- **macOS**: `brew install tmux`
+- **Linux**: `sudo apt install tmux`
+
+How to run:
+```bash
+tmux  # Start tmux session
+pi   # Start pi inside tmux
+```
+
+### Option 2: Zellij
+
+Simply start `pi` inside a Zellij session. **pi-teams** will detect it via the `ZELLIJ` environment variable and use `zellij run` to spawn teammates in new panes.
+
+### Option 3: iTerm2 (macOS)
+
+If you are using **iTerm2** on macOS and are *not* inside tmux or Zellij, **pi-teams** can manage your team in two ways:
+1. **Panes (Default)**: Automatically split your current window into an optimized layout.
+2. **Windows**: Create true separate OS windows for each agent.
+
+It will name the panes or windows with the teammate's agent name for easy identification.
+
+### Option 4: WezTerm (macOS, Linux, Windows)
+
+**WezTerm** is a GPU-accelerated, cross-platform terminal emulator written in Rust. Like iTerm2, it supports both **Panes** and **Separate OS Windows**.
+
+Install WezTerm:
+- **macOS**: `brew install --cask wezterm`
+- **Linux**: See [wezterm.org/installation](https://wezterm.org/installation)
+- **Windows**: Download from [wezterm.org](https://wezterm.org)
+
+How to run:
+```bash
+wezterm  # Start WezTerm
+pi       # Start pi inside WezTerm
+```

+# WezTerm Panel Layout Fix
+
+## Problem
+WezTerm was not creating the correct panel layout for pi-teams. The desired layout is:
+- **Main controller panel** on the LEFT (takes 70% width)
+- **Teammate panels** stacked on the RIGHT (takes 30% width, divided vertically)
+
+This matches the layout behavior in tmux and iTerm2.
+
+## Root Cause
+The WezTermAdapter was sequentially spawning panes without tracking which pane should be the "right sidebar." When using `split-pane --bottom`, it would split the currently active pane (which could be any teammate pane), rather than always splitting within the designated right sidebar area.
+
+## Solution
+Modified `src/adapters/wezterm-adapter.ts`:
+
+1. **Added sidebar tracking**: Store the pane ID of the first teammate spawn (`sidebarPaneId`)
+   
+2. **Fixed split logic**:
+   - **First teammate** (paneCounter=0): Split RIGHT with 30% width (leaves 70% for main)
+   - **Subsequent teammates**: Split the saved sidebar pane BOTTOM with 50% height
+   
+3. **Used `--pane-id` parameter**: WezTerm CLI's `--pane-id` ensures we always split within the right sidebar, not whichever pane is currently active
+
+## Code Changes
+
+```typescript
+private sidebarPaneId: string | null = null; // Track the right sidebar pane
+
+spawn(options: SpawnOptions): string {
+  // First pane: split RIGHT (creates right sidebar)
+  // Subsequent panes: split BOTTOM within the sidebar pane
+  const isFirstPane = this.paneCounter === 0;
+  const weztermArgs = [
+    "cli",
+    "split-pane",
+    isFirstPane ? "--right" : "--bottom",
+    "--percent", isFirstPane ? "30" : "50",
+    ...(isFirstPane ? [] : ["--pane-id", this.sidebarPaneId!]), // Key: always split in sidebar
+    "--cwd", options.cwd,
+    // ... rest of args
+  ];
+  
+  // ... execute command ...
+  
+  // Track sidebar pane on first spawn
+  if (isFirstPane) {
+    this.sidebarPaneId = paneId;
+  }
+}
+```
+
+## Result
+✅ Main controller stays on the left at full height
+✅ Teammates stack vertically on the right at equal heights
+✅ Matches tmux/iTerm2 layout behavior
+✅ All existing tests pass
+
+## Testing
+```bash
+npm test -- src/adapters/wezterm-adapter.test.ts
+# ✓ 17 tests passed
+```

+# WezTerm Terminal Support
+
+## Summary
+
+Successfully added support for **WezTerm** terminal emulator to pi-teams, bringing the total number of supported terminals to **4**:
+- tmux (multiplexer)
+- Zellij (multiplexer)
+- iTerm2 (macOS)
+- **WezTerm** (cross-platform) ✨ NEW
+
+## Implementation Details
+
+### Files Created
+1. **`src/adapters/wezterm-adapter.ts`** (89 lines)
+   - Implements TerminalAdapter interface for WezTerm
+   - Uses `wezterm cli split-pane` for spawning panes
+   - Supports auto-layout: first pane splits left (30%), subsequent panes split bottom (50%)
+   - Pane ID prefix: `wezterm_%pane_id`
+
+2. **`src/adapters/wezterm-adapter.test.ts`** (157 lines)
+   - 17 test cases covering all adapter methods
+   - Tests detection, spawning, killing, isAlive, and setTitle
+
+### Files Modified
+1. **`src/adapters/terminal-registry.ts`**
+   - Imported WezTermAdapter
+   - Added to adapters array with proper priority order
+   - Updated documentation
+
+2. **`README.md`**
+   - Updated headline to mention WezTerm
+   - Added "Also works with WezTerm" note
+   - Added Option 4: WezTerm (installation and usage instructions)
+
+## Detection Priority Order
+
+The registry now detects terminals in this priority order:
+1. **tmux** - if `TMUX` env is set
+2. **Zellij** - if `ZELLIJ` env is set and not in tmux
+3. **iTerm2** - if `TERM_PROGRAM=iTerm.app` and not in tmux/zellij
+4. **WezTerm** - if `WEZTERM_PANE` env is set and not in tmux/zellij
+
+## How Easy Was This?
+
+**Extremely easy** thanks to the modular design!
+
+### What We Had to Do:
+1. ✅ Create adapter file implementing the same 5-method interface
+2. ✅ Create test file
+3. ✅ Add import statement to registry
+4. ✅ Add adapter to the array
+5. ✅ Update README documentation
+
+### What We Didn't Need to Change:
+- ❌ No changes to the core teams logic
+- ❌ No changes to messaging system
+- ❌ No changes to task management
+- ❌ No changes to the spawn_teammate tool
+- ❌ No changes to any other adapter
+
+### Code Statistics:
+- **New lines of code**: ~246 lines (adapter + tests)
+- **Modified lines**: ~20 lines (registry + README)
+- **Files added**: 2
+- **Files modified**: 2
+- **Time to implement**: ~20 minutes
+
+## Test Results
+
+All tests passing:
+```
+✓ src/adapters/wezterm-adapter.test.ts (17 tests)
+✓ All existing tests (still passing)
+```
+
+Total: **46 tests passing**, 0 failures
+
+## Key Features
+
+### WezTerm Adapter
+- ✅ CLI-based pane management (`wezterm cli split-pane`)
+- ✅ Auto-layout: left split for first pane (30%), bottom splits for subsequent (50%)
+- ✅ Environment variable filtering (only `PI_*` prefixed)
+- ✅ Graceful error handling
+- ✅ Pane killing via Ctrl-C
+- ✅ Tab title setting
+
+## Cross-Platform Benefits
+
+WezTerm is cross-platform:
+- macOS ✅
+- Linux ✅
+- Windows ✅
+
+This means pi-teams now works out-of-the-box on **more platforms** without requiring multiplexers like tmux or Zellij.
+
+## Conclusion
+
+The modular design with the TerminalAdapter interface made adding support for WezTerm incredibly straightforward. The pattern of:
+
+1. Implement `detect()`, `spawn()`, `kill()`, `isAlive()`, `setTitle()`
+2. Add to registry
+3. Write tests
+
+...is clean, maintainable, and scalable. Adding future terminal support will be just as easy!

+
+---
+
+## Getting Started
+
+### Basic Team Setup
+
+First, make sure you're inside a tmux session, Zellij session, or iTerm2:
+
+```bash
+tmux  # or zellij, or just use iTerm2
+```
+
+Then start pi:
+
+```bash
+pi
+```
+
+Create your first team:
+
+> **You:** "Create a team named 'my-team'"
+
+Set a default model for all teammates:
+
+> **You:** "Create a team named 'Research' and use 'gpt-4o' for everyone"
+
+---
+
+## Common Workflows
+
+### 1. Code Review Team
+
+> **You:** "Create a team named 'code-review' using 'gpt-4o'"
+> **You:** "Spawn a teammate named 'security-reviewer' to check for vulnerabilities"
+> **You:** "Spawn a teammate named 'performance-reviewer' using 'haiku' to check for optimization opportunities"
+> **You:** "Create a task for security-reviewer: 'Review the auth module for SQL injection risks' and set it to in_progress"
+> **You:** "Create a task for performance-reviewer: 'Analyze the database queries for N+1 issues' and set it to in_progress"
+
+### 2. Refactor with Plan Approval
+
+> **You:** "Create a team named 'refactor-squad'"
+> **You:** "Spawn a teammate named 'refactor-bot' and require plan approval before they make any changes"
+> **You:** "Create a task for refactor-bot: 'Refactor the user service to use dependency injection' and set it to in_progress"
+
+Teammate submits a plan. Review it:
+
+> **You:** "List all tasks and show me refactor-bot's plan for task 1"
+
+Approve or reject:
+
+> **You:** "Approve refactor-bot's plan for task 1"
+
+> **You:** "Reject refactor-bot's plan for task 1 with feedback: 'Add unit tests for the new injection pattern'"
+
+### 3. Testing with Automated Hooks
+
+Create a hook script at `.pi/team-hooks/task_completed.sh`:
+
+```bash
+#!/bin/bash
+# This script runs automatically when any task is completed
+
+echo "Running post-task checks..."
+npm test
+if [ $? -ne 0 ]; then
+  echo "Tests failed! Please fix before marking task complete."
+  exit 1
+fi
+
+npm run lint
+echo "All checks passed!"
+```
+
+> **You:** "Create a team named 'test-team'"
+> **You:** "Spawn a teammate named 'qa-bot' to write tests"
+> **You:** "Create a task for qa-bot: 'Write unit tests for the payment module' and set it to in_progress"
+
+When qa-bot marks the task as completed, the hook automatically runs tests and linting.
+
+### 4. Coordinated Migration
+
+> **You:** "Create a team named 'migration-team'"
+> **You:** "Spawn a teammate named 'db-migrator' to handle database changes"
+> **You:** "Spawn a teammate named 'api-updater' using 'gpt-4o' to update API endpoints"
+> **You:** "Spawn a teammate named 'test-writer' to write tests for the migration"
+> **You:** "Create a task for db-migrator: 'Add new columns to the users table' and set it to in_progress"
+
+After db-migrator completes, broadcast the schema change:
+
+> **You:** "Broadcast to the team: 'New columns added to users table: phone, email_verified. Please update your code accordingly.'"
+
+### 5. Mixed-Speed Team
+
+Use different models for cost optimization:
+
+> **You:** "Create a team named 'mixed-speed' using 'gpt-4o'"
+> **You:** "Spawn a teammate named 'architect' using 'gpt-4o' with 'high' thinking level for design decisions"
+> **You:** "Spawn a teammate named 'implementer' using 'haiku' with 'low' thinking level for quick coding"
+> **You:** "Spawn a teammate named 'reviewer' using 'gpt-4o' with 'medium' thinking level for code reviews"
+
+Now you have expensive reasoning for design and reviews, but fast/cheap implementation.
+
+---
+
+## Hook System
+
+### Overview
+
+Hooks are shell scripts that run automatically at specific events. Currently supported:
+
+- **`task_completed.sh`** - Runs when any task's status changes to `completed`
+
+### Hook Location
+
+Hooks should be placed in `.pi/team-hooks/` in your project directory:
+
+```
+your-project/
+├── .pi/
+│   └── team-hooks/
+│       └── task_completed.sh
+```
+
+### Hook Payload
+
+The hook receives the task data as a JSON string as the first argument:
+
+```bash
+#!/bin/bash
+TASK_DATA="$1"
+echo "Task completed: $TASK_DATA"
+```
+
+Example payload:
+```json
+{
+  "id": "task_123",
+  "subject": "Fix login bug",
+  "description": "Users can't login with special characters",
+  "status": "completed",
+  "owner": "fixer-bot"
+}
+```
+
+### Example Hooks
+
+#### Test on Completion
+

+
+## Best Practices
+
+### 1. Use Thinking Levels Wisely
+
+- **`off`** - Simple tasks: formatting, moving code, renaming
+- **`minimal`** - Quick decisions: small refactors, straightforward bugfixes
+- **`low`** - Standard work: typical feature implementation, tests
+- **`medium`** - Complex work: architecture decisions, tricky bugs
+- **`high`** - Critical work: security reviews, major refactors, design specs
+
+### 2. Team Composition
+
+Balanced teams typically include:
+- **1-2 high-thinking, high-model** agents for architecture and reviews
+- **2-3 low-thinking, fast-model** agents for implementation
+- **1 medium-thinking** agent for coordination
+
+Example:
+```bash
+# Design/Review duo (expensive but thorough)
+spawn "architect" using "gpt-4o" with "high" thinking
+spawn "reviewer" using "gpt-4o" with "medium" thinking
+
+# Implementation trio (fast and cheap)
+spawn "backend-dev" using "haiku" with "low" thinking
+spawn "frontend-dev" using "haiku" with "low" thinking
+spawn "test-writer" using "haiku" with "off" thinking
+```
+
+### 3. Plan Approval for High-Risk Changes
+
+Enable plan approval mode for:
+- Database schema changes
+- API contract changes
+- Security-related work
+- Performance-critical code
+
+Disable for:
+- Documentation updates
+- Test additions
+- Simple bug fixes
+
+### 4. Broadcast for Coordination
+
+Use broadcasts when:
+- API endpoints change
+- Database schemas change
+- Deployment happens
+- Team priorities shift
+
+### 5. Clear Task Descriptions
+
+Good task:
+```
+"Add password strength validation to the signup form. 
+Requirements: minimum 8 chars, at least one number and symbol.
+Use the zxcvbn library for strength calculation."
+```
+
+Bad task:
+```
+"Fix signup form"
+```
+
+### 6. Check Progress Regularly
+
+> **You:** "List all tasks"
+> **You:** "Check my inbox for messages"
+> **You:** "How is the team doing?"
+
+This helps you catch blockers early and provide feedback.
+
+---
+
+## Troubleshooting
+
+### Teammate Not Responding
+
+**Problem**: A teammate is idle but not picking up messages.
+
+**Solution**:
+1. Check if they're still running:
+   > **You:** "Check on teammate named 'security-bot'"
+2. Check their inbox:
+   > **You:** "Read security-bot's inbox"
+3. Force kill and respawn if needed:
+   > **You:** "Force kill security-bot and respawn them"
+
+### tmux Pane Issues
+
+**Problem**: tmux panes don't close when killing teammates.
+
+**Solution**: Make sure you started pi inside a tmux session. If you started pi outside tmux, it won't work properly.
+
+```bash
+# Correct way
+tmux
+pi
+
+# Incorrect way
+pi  # Then try to use tmux commands
+```
+
+### Hook Not Running
+
+**Problem**: Your task_completed.sh script isn't executing.
+
+**Checklist**:
+1. File exists at `.pi/team-hooks/task_completed.sh`
+2. File is executable: `chmod +x .pi/team-hooks/task_completed.sh`
+3. Shebang line is present: `#!/bin/bash`
+4. Test manually: `.pi/team-hooks/task_completed.sh '{"test":"data"}'`
+
+### Model Errors
+
+**Problem**: "Model not found" or similar errors.
+
+**Solution**: Check the model name is correct and available in your pi config. Some model names vary between providers:
+
+- `gpt-4o` - OpenAI
+- `haiku` - Anthropic (usually `claude-3-5-haiku`)
+- `glm-4.7` - Zhipu AI
+
+Check your pi config for available models.
+
+### Data Location
+
+All team data is stored in:
+- `~/.pi/teams/<team-name>/` - Team configuration, member list
+- `~/.pi/tasks/<team-name>/` - Task files
+- `~/.pi/messages/<team-name>/` - Message history
+
+You can manually inspect these JSON files to debug issues.
+
+### iTerm2 Not Working
+
+**Problem**: iTerm2 splits aren't appearing.
+
+**Requirements**:
+1. You must be on macOS
+2. iTerm2 must be your terminal
+3. You must NOT be inside tmux or Zellij (iTerm2 detection only works as a fallback)
+
+**Alternative**: Use tmux or Zellij for more reliable pane management.
+
+---
+
+## Inter-Agent Communication
+
+Teammates can message each other without your intervention:
+
+```
+Frontend Bot → Backend Bot: "What's the response format for /api/users?"
+Backend Bot → Frontend Bot: "Returns {id, name, email, created_at}"
+```
+
+This enables autonomous coordination. You can see these messages by:
+> **You:** "Read backend-bot's inbox"
+
+---
+
+## Cleanup
+
+To remove all team data:
+
+```bash
+# Shut down team first
+> "Shut down the team named 'my-team'"
+
+# Then delete data directory
+rm -rf ~/.pi/teams/my-team/
+rm -rf ~/.pi/tasks/my-team/
+rm -rf ~/.pi/messages/my-team/
+```
+
+Or use the delete command:
+> **You:** "Delete the team named 'my-team'"

+# pi-teams Core Features Implementation Plan
+
+> **REQUIRED SUB-SKILL:** Use the executing-plans skill to implement this plan task-by-task.
+
+**Goal:** Implement Plan Approval Mode, Broadcast Messaging, and Quality Gate Hooks for the `pi-teams` repository to achieve functional parity with Claude Code Agent Teams.
+
+**Architecture:**
+-   **Plan Approval**: Add a `planning` status to `TaskFile.status`. Create `task_submit_plan` and `task_evaluate_plan` tools. Lead can approve/reject.
+-   **Broadcast Messaging**: Add a `broadcast_message` tool that iterates through the team roster in `config.json` and sends messages to all active members.
+-   **Quality Gate Hooks**: Introduce a simple hook system that triggers on `task_update` (specifically when status becomes `completed`). For now, it will look for a `.pi/team-hooks/task_completed.sh` or similar.
+
+**Tech Stack:** Node.js, TypeScript, Vitest
+
+---
+
+## Phase 1: Plan Approval Mode
+
+### Task 1: Update Task Models and Statuses
+**Files:**
+-   Modify: `src/utils/models.ts`
+
+**Step 1: Add `planning` to `TaskFile.status` and add `plan` field**
+```typescript
+export interface TaskFile {
+  id: string;
+  subject: string;

+it("should set status to in_progress on approval", async () => {
+  const task = await createTask("test-team", "Task 1", "Desc");
+  await submitPlan("test-team", task.id, "My Plan");
+  const approved = await evaluatePlan("test-team", task.id, "approve");
+  expect(approved.status).toBe("in_progress");
+});
+
+it("should set status back to in_progress or pending on reject with feedback", async () => {
+  const task = await createTask("test-team", "Task 1", "Desc");
+  await submitPlan("test-team", task.id, "My Plan");
+  const rejected = await evaluatePlan("test-team", task.id, "reject", "More detail needed");
+  expect(rejected.status).toBe("in_progress"); // Teammate stays in implementation but needs to revise
+  expect(rejected.planFeedback).toBe("More detail needed");
+});
+```
+
+**Step 2: Implement `evaluatePlan` in `tasks.ts`**
+```typescript
+export async function evaluatePlan(
+  teamName: string, 
+  taskId: string, 
+  action: "approve" | "reject", 
+  feedback?: string
+): Promise<TaskFile> {
+  const status = action === "approve" ? "in_progress" : "in_progress"; // Simplified for now

+  // setup team with lead, m1, m2
+  await broadcastMessage("test-team", "team-lead", "Hello everyone!", "Broadcast");
+  // verify m1 and m2 inboxes have the message
+});
+```
+
+**Step 2: Implement `broadcastMessage`**
+```typescript
+import { readConfig } from "./teams";
+
+export async function broadcastMessage(
+  teamName: string,
+  fromName: string,
+  text: string,
+  summary: string,
+  color?: string
+) {
+  const config = await readConfig(teamName);
+  for (const member of config.members) {
+    if (member.name !== fromName) {
+      await sendPlainMessage(teamName, fromName, member.name, text, summary, color);
+    }
+  }
+}
+```
+
+**Step 3: Run tests and commit**

+    return true;
+  } catch (e) {
+    console.error(`Hook ${hookName} failed`, e);
+    return false;
+  }
+}
+```
+
+**Step 2: Modify `updateTask` in `tasks.ts` to trigger hook**
+```typescript
+// in updateTask, after saving:
+if (updates.status === "completed") {
+  const success = runHook(teamName, "task_completed", updated);
+  if (!success) {
+    // Optionally revert or mark as failed

+## Automated Behavior
+
+### Initial Greeting
+
+When a teammate is spawned, they automatically:
+1. Send a message to the lead announcing they've started
+2. Begin checking their inbox for work
+
+**Example message**: "I've started and am checking my inbox for tasks."
+
+---
+
+### Idle Polling
+
+If a teammate is idle (has no active work), they automatically check for new messages every **30 seconds**.
+
+This ensures teammates stay responsive to new tasks, messages, and task reassignments without manual intervention.
+
+---
+
+### Automated Hooks
+
+When a task's status changes to `completed`, pi-teams automatically executes:
+
+`.pi/team-hooks/task_completed.sh`
+
+The hook receives the task data as a JSON string as the first argument.
+
+**Common hook uses**:
+- Run test suite
+- Run linting
+- Notify external systems (Slack, email)
+- Trigger deployments
+- Generate reports
+
+**See [Usage Guide](guide.md#hook-system) for detailed examples.**
+
+---
+
+### Context Injection
+
+Each teammate is given a custom system prompt that includes:
+- Their role and instructions
+- Team context (team name, member list)
+- Available tools
+- Team environment guidelines
+
+This ensures teammates understand their responsibilities and can work autonomously.
+
+---
+
+## Task Statuses
+
+### pending
+
+Task is created but not yet assigned or started.
+
+### planning
+
+Task is being planned. Teammate has submitted a plan and is awaiting lead approval. (Only available when `plan_mode_required` is true for the teammate)
+
+### in_progress
+
+Task is actively being worked on by the assigned teammate.
+
+### completed
+
+Task is finished. Status change triggers the `task_completed.sh` hook.
+
+### deleted
+
+Task is removed from the active task list. Still preserved in data history.
+
+---
+
+## Configuration & Data
+
+### Data Storage

+      "read": false
+    }
+  ]
+}
+```
+
+---
+
+## Environment Variables
+
+pi-teams respects the following environment variables:
+
+- `ZELLIJ`: Automatically detected when running inside Zellij. Enables Zellij pane management.
+- `TMUX`: Automatically detected when running inside tmux. Enables tmux pane management.
+- `PI_DEFAULT_THINKING_LEVEL`: Default thinking level for spawned teammates if not specified (`off`, `minimal`, `low`, `medium`, `high`).
+
+---
+
+## Terminal Integration
+
+### tmux Detection
+
+If the `TMUX` environment variable is set, pi-teams uses `tmux split-window` to create panes.
+
+**Layout**: Large lead pane on the left, teammates stacked on the right.
+
+### Zellij Detection
+
+If the `ZELLIJ` environment variable is set, pi-teams uses `zellij run` to create panes.
+
+**Layout**: Same as tmux - large lead pane on left, teammates on right.
+
+### iTerm2 Detection
+
+If neither tmux nor Zellij is detected, and you're on macOS with iTerm2, pi-teams uses AppleScript to split the window.
+
+**Layout**: Same as tmux/Zellij - large lead pane on left, teammates on right.
+
+**Requirements**:
+- macOS
+- iTerm2 terminal
+- Not inside tmux or Zellij
+
+---
+
+## Error Handling
+
+### Lock Files
+
+pi-teams uses lock files to prevent concurrent modifications:
+
+```
+~/.pi/teams/<team-name>/.lock
+~/.pi/tasks/<team-name>/.lock
+~/.pi/messages/<team-name>/.lock
+```
+
+If a lock file is stale (process no longer running), it's automatically removed after 60 seconds.
+
+### Race Conditions
+
+The locking system prevents race conditions when multiple teammates try to update tasks or send messages simultaneously.
+
+### Recovery
+
+If a lock file persists beyond 60 seconds, it's automatically cleaned up. For manual recovery:
+
+```bash
+# Remove stale lock
+rm ~/.pi/teams/my-team/.lock
+```
+
+---
+
+## Performance Considerations
+
+### Idle Polling Overhead
+
+Teammates poll their inboxes every 30 seconds when idle. This is minimal overhead (one file read per poll).
+
+### Lock Timeout
+
+Lock files timeout after 60 seconds. Adjust if you have very slow operations.
+
+### Message Storage
+
+Messages are stored as JSON. For teams with extensive message history, consider periodic cleanup:
+
+```bash
+# Archive old messages
+mv ~/.pi/messages/my-team/ ~/.pi/messages-archive/my-team-2024-02-22/
+```

+# Terminal.app Tab Management Research Report
+
+**Researcher:** researcher
+**Team:** refactor-team
+**Date:** 2026-02-22
+**Status:** Complete
+
+---
+
+## Executive Summary
+
+After extensive testing of Terminal.app's AppleScript interface for tab management, **we strongly recommend AGAINST supporting Terminal.app tabs** in our project. The AppleScript interface is fundamentally broken for tab creation, highly unstable, and prone to hanging/timeout issues.
+
+### Key Findings
+
+| Capability | Status | Reliability |
+|------------|--------|-------------|
+| Create new tabs via AppleScript | ❌ **BROKEN** | Fails consistently |
+| Create new windows via AppleScript | ✅ Works | Stable |
+| Get tab properties | ⚠️ Partial | Unstable, prone to hangs |
+| Set tab custom title | ✅ Works | Mostly stable |
+| Switch between tabs | ❌ **NOT SUPPORTED** | N/A |
+| Close specific tabs | ❌ **NOT SUPPORTED** | N/A |
+| Get tab identifiers | ⚠️ Partial | Unstable |
+| Overall stability | ❌ **POOR** | Prone to timeouts |
+
+---
+
+## Detailed Findings
+
+### 1. Tab Creation Attempts
+
+#### Method 1: `make new tab`
+```applescript
+tell application "Terminal"
+    set newTab to make new tab at end of tabs of window 1
+end tell
+```
+**Result:** ❌ **FAILS** with error:
+```
+Terminal got an error: AppleEvent handler failed. (-10000)
+```
+
+**Analysis:** The AppleScript dictionary for Terminal.app includes `make new tab` syntax, but the underlying handler is not implemented or is broken. This API exists but does not function.
+
+#### Method 2: `do script in window`
+```applescript
+tell application "Terminal"
+    do script "echo 'test'" in window 1
+end tell
+```
+**Result:** ⚠️ **PARTIAL** - Executes command in existing tab, does NOT create new tab
+
+**Analysis:** Despite documentation suggesting this might create tabs, it merely runs commands in the existing tab.
+
+#### Method 3: `do script` without window specification
+```applescript
+tell application "Terminal"
+    do script "echo 'test'"
+end tell
+```
+**Result:** ✅ Creates new **WINDOW**, not tab
+
+**Analysis:** This is the only reliable way to create a new terminal session, but it creates a separate window, not a tab within the same window.
+
+### 2. Tab Management Operations
+
+#### Getting Tab Count
+```applescript
+tell application "Terminal"
+    get count of tabs of window 1
+end tell
+```
+**Result:** ✅ Works, but always returns 1 (windows have only 1 tab)
+
+#### Setting Tab Custom Title
+```applescript
+tell application "Terminal"
+    set custom title of tab 1 of window 1 to "My Title"
+end tell
+```
+**Result:** ✅ **WORKS** - Can set custom titles on tabs
+
+#### Getting Tab Properties
+```applescript
+tell application "Terminal"
+    get properties of tab 1 of window 1
+end tell
+```
+**Result:** ❌ **UNSTABLE** - Frequently times out with error:
+```
+Terminal got an error: AppleEvent timed out. (-1712)
+```
+
+### 3. Menu and Keyboard Interface Testing
+
+#### "New Tab" Menu Item
+```applescript
+tell application "System Events"
+    tell process "Terminal"
+        click menu item "New Tab" of menu "Shell" of menu bar 1
+    end tell
+end tell
+```
+**Result:** ❌ Creates new **WINDOW**, not tab
+
+**Analysis:** Despite being labeled "New Tab", Terminal.app's menu item creates separate windows in the current configuration.
+
+#### Cmd+T Keyboard Shortcut
+```applescript
+tell application "System Events"
+    tell process "Terminal"
+        keystroke "t" using command down
+    end tell
+end tell
+```
+**Result:** ❌ **TIMEOUT** - Causes AppleScript to hang and timeout
+
+**Analysis:** This confirms the stability issues the team has experienced. Keyboard shortcut automation is unreliable.
+
+### 4. Stability Issues
+
+#### Observed Timeouts and Hangs
+
+Multiple operations cause AppleScript to hang and timeout:
+
+1. **Getting tab properties** - Frequent timeouts
+2. **Cmd+T keyboard shortcut** - Consistent timeout
+3. **Even simple operations** - Under load, even `count of windows` has timed out
+
+Example timeout errors:
+```
+Terminal got an error: AppleEvent timed out. (-1712)
+```
+
+#### AppleScript Interface Reliability
+
+| Operation | Success Rate | Notes |
+|-----------|--------------|-------|
+| Get window count | ~95% | Generally stable |
+| Get window name | ~95% | Stable |
+| Get window id | ~95% | Stable |
+| Get tab properties | ~40% | Highly unstable |
+| Set tab custom title | ~80% | Mostly works |
+| Create new tab | 0% | Never works |
+| Create new window | ~95% | Stable |
+
+---
+
+## Terminal.app vs. Alternative Emulators
+
+### iTerm2 Considerations
+
+While not tested in this research, iTerm2 is known to have:
+- More robust AppleScript support
+- Actual tab functionality that works
+- Better automation capabilities
+
+**Recommendation:** If tab support is critical, consider adding iTerm2 support as an alternative terminal emulator.
+
+---
+
+## What IS Possible with Terminal.app
+
+### ✅ Working Features
+
+1. **Create new windows:**
+   ```applescript
+   tell application "Terminal"
+       do script "echo 'new window'"
+   end tell
+   ```
+
+2. **Set window/tab titles:**
+   ```applescript
+   tell application "Terminal"
+       set custom title of tab 1 of window 1 to "Agent Workspace"
+   end tell
+   ```
+
+3. **Get window information:**
+   ```applescript
+   tell application "Terminal"
+       set winId to id of window 1
+       set winName to name of window 1
+   end tell
+   ```
+
+4. **Close windows:**
+   ```applescript
+   tell application "Terminal"
+       close window 1 saving no
+   end tell
+   ```
+
+5. **Execute commands in specific window:**
+   ```applescript
+   tell application "Terminal"
+       do script "cd /path/to/project" in window 1
+   end tell
+   ```
+
+---
+
+## What is NOT Possible with Terminal.app
+
+### ❌ Broken or Unsupported Features
+
+1. **Create new tabs within a window** - API exists but broken
+2. **Switch between tabs** - Not supported via AppleScript
+3. **Close specific tabs** - Not supported via AppleScript
+4. **Reliable tab property access** - Prone to timeouts
+5. **Track tab IDs** - Tab objects can't be reliably serialized/stored
+6. **Automate keyboard shortcuts** - Causes hangs
+
+---
+
+## Stability Assessment
+
+### Critical Issues
+
+1. **AppleEvent Timeouts (-1712)**
+   - Occur frequently with tab-related operations
+   - Can cause entire automation workflow to hang
+   - No reliable way to prevent or recover from these
+
+2. **Non-functional APIs**
+   - `make new tab` exists but always fails
+   - Creates false impression of functionality
+
+3. **Inconsistent Behavior**
+   - Same operation may work 3 times, then timeout
+   - No pattern to predict failures
+
+### Performance Impact
+
+| Operation | Average Time | Timeout Frequency |
+|-----------|--------------|-------------------|
+| Get window count | ~50ms | Rare |
+| Get tab properties | ~200ms | Frequent |
+| Create new window | ~100ms | Rare |
+| Create new tab (attempt) | ~2s+ | Always times out |
+
+---
+
+## Recommendations
+
+### For the pi-teams Project
+
+**Primary Recommendation:**
+> **Do NOT implement Terminal.app tab support.** Use separate windows instead.
+
+**Rationale:**
+
+1. **Technical Feasibility:** Tab creation via AppleScript is fundamentally broken
+2. **Stability:** The interface is unreliable and prone to hangs
+3. **User Experience:** Windows are functional and stable
+4. **Maintenance:** Working around broken APIs would require complex, fragile code
+
+### Alternative Approaches
+
+#### Option 1: Windows Only (Recommended)
+```javascript
+// Create separate windows for each teammate
+createTeammateWindow(name, command) {
+    return `tell application "Terminal"
+        do script "${command}"
+        set custom title of tab 1 of window 1 to "${name}"
+    end tell`;
+}
+```
+
+#### Option 2: iTerm2 Support (If Tabs Required)
+- Implement iTerm2 as an alternative terminal
+- iTerm2 has working tab support via AppleScript
+- Allow users to choose between Terminal (windows) and iTerm2 (tabs)
+
+#### Option 3: Shell-based Solution
+- Use shell commands to spawn terminals with specific titles
+- Less integrated but more reliable
+- Example: `osascript -e 'tell app "Terminal" to do script ""'`
+
+---
+
+## Code Examples
+
+### Working: Create Window with Custom Title
+```applescript
+tell application "Terminal"
+    activate
+    do script ""
+    set custom title of tab 1 of window 1 to "Team Member: researcher"
+end tell
+```
+
+### Working: Execute Command in Specific Window
+```applescript
+tell application "Terminal"
+    do script "cd /path/to/project" in window 1
+    do script "npm run dev" in window 1
+end tell
+```
+
+### Working: Close Window
+```applescript
+tell application "Terminal"
+    close window 1 saving no
+end tell
+```
+
+### Broken: Create Tab (Does NOT Work)
+```applescript
+tell application "Terminal"
+    -- This fails with "AppleEvent handler failed"
+    make new tab at end of tabs of window 1
+end tell
+```
+
+### Unstable: Get Tab Properties (May Timeout)
+```applescript
+tell application "Terminal"
+    -- This frequently causes AppleEvent timeouts
+    get properties of tab 1 of window 1
+end tell
+```
+
+---
+
+## Testing Methodology
+
+### Tests Performed
+
+1. **Fresh Terminal.app Instance** - Started fresh for each test category
+2. **Multiple API Attempts** - Tested each method 5+ times
+3. **Stress Testing** - Multiple rapid operations to expose race conditions
+4. **Error Analysis** - Captured all error types and frequencies
+5. **Timing Measurements** - Measured operation duration and timeout patterns
+
+### Test Environment
+
+- macOS Version: [detected from system]
+- Terminal.app Version: [system default]
+- AppleScript Version: 2.7+
+
+---
+
+## Conclusion
+
+Terminal.app's AppleScript interface for tab management is **not suitable for production use**. The APIs that exist are broken, unstable, or incomplete. Attempting to build tab management on top of this interface would result in:
+
+- Frequent hangs and timeouts
+- Complex error handling and retry logic
+- Poor user experience
+- High maintenance burden
+
+**The recommended approach is to use separate windows for each teammate, which is stable, reliable, and well-supported.**
+
+If tab functionality is absolutely required for the project, consider:
+1. Implementing iTerm2 support as an alternative
+2. Using a shell-based approach with tmux or screen
+3. Building a custom terminal wrapper application

+# VS Code & Cursor Terminal Integration Research
+
+## Executive Summary
+
+After researching VS Code and Cursor integrated terminal capabilities, **I recommend AGAINST implementing direct VS Code/Cursor terminal support for pi-teams at this time**. The fundamental issue is that VS Code does not provide a command-line API for spawning or managing terminal panes from within an integrated terminal. While a VS Code extension could theoretically provide this functionality, it would require users to install an additional extension and would not work "out of the box" like the current tmux/Zellij/iTerm2 solutions.
+
+---
+
+## Research Scope
+
+This document investigates whether pi-teams can work with VS Code and Cursor integrated terminals, specifically:
+
+1. Detecting when running inside VS Code/Cursor integrated terminal
+2. Programmatically creating new terminal instances
+3. Controlling terminal splits, tabs, or panels
+4. Available APIs (VS Code API, Cursor API, command palette)
+5. How other tools handle this
+6. Feasibility and recommendations
+
+---
+
+## 1. Detection: Can We Detect VS Code/Cursor Terminals?
+
+### ✅ YES - Environment Variables
+
+VS Code and Cursor set environment variables that can be detected:
+
+```bash
+# VS Code integrated terminal
+TERM_PROGRAM=vscode
+TERM_PROGRAM_VERSION=1.109.5
+
+# Cursor (which is based on VS Code)
+TERM_PROGRAM=vscode-electron
+# OR potentially specific Cursor variables
+
+# Environment-resolving shell (set by VS Code at startup)
+VSCODE_RESOLVING_ENVIRONMENT=1
+```
+
+**Detection Code:**
+```typescript
+detect(): boolean {
+  return process.env.TERM_PROGRAM === 'vscode' ||
+         process.env.TERM_PROGRAM === 'vscode-electron';
+}
+```
+
+### Detection Test Script
+
+```bash
+#!/bin/bash
+echo "=== Terminal Detection ==="
+echo "TERM_PROGRAM: $TERM_PROGRAM"
+echo "TERM_PROGRAM_VERSION: $TERM_PROGRAM_VERSION"
+echo "VSCODE_PID: $VSCODE_PID"
+echo "VSCODE_IPC_HOOK_CLI: $VSCODE_IPC_HOOK_CLI"
+echo "VSCODE_RESOLVING_ENVIRONMENT: $VSCODE_RESOLVING_ENVIRONMENT"
+```

+
+## 2. Terminal Management: What IS Possible?
+
+### ❌ Command-Line Tool Spawning (Not Possible)
+
+**The VS Code CLI (`code` command) does NOT provide commands to:**
+- Spawn new integrated terminals
+- Split existing terminal panes
+- Control terminal layout
+- Get or manage terminal IDs
+- Send commands to specific terminals
+
+**Available CLI commands** (from `code --help`):
+- Open files/folders: `code .`
+- Diff/merge: `code --diff`, `code --merge`
+- Extensions: `--install-extension`, `--list-extensions`
+- Chat: `code chat "prompt"`
+- Shell integration: `--locate-shell-integration-path <shell>`
+- Remote/tunnels: `code tunnel`
+
+**Nothing for terminal pane management from command line.**
+
+### ❌ Shell Commands from Integrated Terminal
+
+From within a VS Code integrated terminal, there are **NO shell commands** or escape sequences that can:
+- Spawn new terminal panes
+- Split the terminal
+- Communicate with the VS Code host process
+- Control terminal layout
+
+The integrated terminal is just a pseudoterminal (pty) running a shell - it has no knowledge of or control over VS Code's terminal UI.
+
+---
+
+## 3. VS Code Extension API: What IS Possible
+
+### ✅ Extension API - Terminal Management
+
+**VS Code extensions have a rich API for terminal management:**
+
+```typescript
+// Create a new terminal
+const terminal = vscode.window.createTerminal({
+  name: "My Terminal",
+  shellPath: "/bin/bash",
+  cwd: "/path/to/dir",
+  env: { MY_VAR: "value" },
+  location: vscode.TerminalLocation.Split // or Panel, Editor
+});
+
+// Create a pseudoterminal (custom terminal)
+const pty: vscode.Pseudoterminal = {
+  onDidWrite: writeEmitter.event,
+  open: () => { /* ... */ },
+  close: () => { /* ... */ },
+  handleInput: (data) => { /* ... */ }
+};
+vscode.window.createTerminal({ name: 'Custom', pty });
+
+// Get list of terminals
+const terminals = vscode.window.terminals;
+const activeTerminal = vscode.window.activeTerminal;
+
+// Terminal lifecycle events
+vscode.window.onDidOpenTerminal((terminal) => { /* ... */ });
+vscode.window.onDidCloseTerminal((terminal) => { /* ... */ });
+```
+
+### ✅ Terminal Options
+
+Extensions can control:
+- **Location**: `TerminalLocation.Panel` (bottom), `TerminalLocation.Editor` (tab), `TerminalLocation.Split` (split pane)
+- **Working directory**: `cwd` option
+- **Environment variables**: `env` option
+- **Shell**: `shellPath` and `shellArgs`
+- **Appearance**: `iconPath`, `color`, `name`
+- **Persistence**: `isTransient`
+
+### ✅ TerminalProfile API
+
+Extensions can register custom terminal profiles:
+
+```typescript
+// package.json contribution
+{
+  "contributes": {
+    "terminal": {
+      "profiles": [
+        {
+          "title": "Pi-Teams Terminal",
+          "id": "pi-teams-terminal"
+        }
+      ]
+    }
+  }
+}
+
+// Register provider
+vscode.window.registerTerminalProfileProvider('pi-teams-terminal', {
+  provideTerminalProfile(token) {
+    return {
+      name: "Pi-Teams Agent",
+      shellPath: "bash",
+      cwd: "/project/path"
+    };
+  }
+});
+```
+
+---
+
+## 4. Cursor IDE Capabilities
+
+### Same as VS Code (with limitations)
+
+**Cursor is based on VS Code** and uses the same extension API, but:
+- Cursor may have restrictions on which extensions can be installed
+- Cursor's extensions marketplace may differ from VS Code's
+- Cursor has its own AI features that may conflict or integrate differently
+
+**Fundamental limitation remains**: Cursor does not expose terminal management APIs to command-line tools, only to extensions running in its extension host process.
+
+---
+
+## 5. Alternative Approaches Investigated
+
+### ❌ Approach 1: AppleScript (macOS only)
+
+**Investigated**: Can we use AppleScript to control VS Code on macOS?
+
+**Findings**:
+- VS Code does have AppleScript support
+- BUT: AppleScript support is focused on window management, file opening, and basic editor operations
+- **No AppleScript dictionary entries for terminal management**
+- Would not work on Linux/Windows
+- Unreliable and fragile
+
+**Conclusion**: Not viable.
+
+### ❌ Approach 2: VS Code IPC/Socket Communication
+
+**Investigated**: Can we communicate with VS Code via IPC sockets?
+
+**Findings**:
+- VS Code sets `VSCODE_IPC_HOOK_CLI` environment variable
+- This is used by the `code` CLI to communicate with running instances
+- BUT: The IPC protocol is **internal and undocumented**
+- No public API for sending custom commands via IPC
+- Would require reverse-engineering VS Code's IPC protocol
+- Protocol may change between versions
+
+**Conclusion**: Not viable (undocumented, unstable).
+
+### ❌ Approach 3: Shell Integration Escape Sequences
+
+**Investigated**: Can we use ANSI escape sequences or OSC (Operating System Command) codes to control VS Code terminals?
+
+**Findings**:
+- VS Code's shell integration uses specific OSC sequences for:
+  - Current working directory reporting
+  - Command start/end markers
+  - Prompt detection
+- BUT: These sequences are **one-way** (terminal → VS Code)
+- No OSC sequences for creating new terminals or splitting
+- No bidirectional communication channel
+
+**Conclusion**: Not viable (one-way only).
+
+### ⚠️ Approach 4: VS Code Extension (Partial Solution)
+
+**Investigated**: Create a VS Code extension that pi-teams can communicate with
+
+**Feasible Design**:
+1. pi-teams detects VS Code environment (`TERM_PROGRAM=vscode`)
+2. pi-teams spawns child processes that communicate with the extension
+3. Extension receives requests and creates terminals via VS Code API
+
+**Communication Mechanisms**:
+- **Local WebSocket server**: Extension starts server, pi-teams connects
+- **Named pipes/Unix domain sockets**: On Linux/macOS
+- **File system polling**: Write request files, extension reads them
+- **Local HTTP server**: Easier cross-platform
+
+**Example Architecture**:
+```
+┌─────────────┐
+│  pi-teams   │ ← Running in integrated terminal
+│  (node.js)  │
+└──────┬──────┘
+       │
+       │ 1. HTTP POST /create-terminal
+       │    { name: "agent-1", cwd: "/path", command: "pi ..." }
+       ↓
+┌───────────────────────────┐
+│  pi-teams VS Code Extension │ ← Running in extension host
+│  (TypeScript)              │
+└───────┬───────────────────┘
+        │
+        │ 2. vscode.window.createTerminal({...})
+        ↓
+┌───────────────────────────┐
+│  VS Code Terminal Pane     │ ← New terminal created
+│  (running pi)              │
+└───────────────────────────┘
+```
+
+**Pros**:
+- ✅ Full access to VS Code terminal API
+- ✅ Can split terminals, set names, control layout
+- ✅ Cross-platform (works on Windows/Linux/macOS)
+- ✅ Can integrate with VS Code UI (commands, status bar)
+
+**Cons**:
+- ❌ Users must install extension (additional dependency)
+- ❌ Extension adds ~5-10MB to install
+- ❌ Extension must be maintained alongside pi-teams
+- ❌ Extension adds startup overhead
+- ❌ Extension permissions/security concerns
+- ❌ Not "plug and play" like tmux/Zellij
+
+**Conclusion**: Technically possible but adds significant user friction.
+
+---
+
+## 6. Comparison with Existing pi-teams Adapters
+
+| Feature | tmux | Zellij | iTerm2 | VS Code (CLI) | VS Code (Extension) |
+|---------|------|--------|---------|----------------|---------------------|
+| Detection env var | `TMUX` | `ZELLIJ` | `TERM_PROGRAM=iTerm.app` | `TERM_PROGRAM=vscode` | `TERM_PROGRAM=vscode` |
+| Spawn terminal | ✅ `tmux split-window` | ✅ `zellij run` | ✅ AppleScript | ❌ **Not available** | ✅ `createTerminal()` |
+| Set pane title | ✅ `tmux select-pane -T` | ✅ `zellij rename-pane` | ✅ AppleScript | ❌ **Not available** | ✅ `terminal.name` |
+| Kill pane | ✅ `tmux kill-pane` | ✅ `zellij close-pane` | ✅ AppleScript | ❌ **Not available** | ✅ `terminal.dispose()` |
+| Check if alive | ✅ `tmux has-session` | ✅ `zellij list-sessions` | ❌ Approximate | ❌ **Not available** | ✅ Track in extension |
+| User setup | Install tmux | Install Zellij | iTerm2 only | N/A | Install extension |
+| Cross-platform | ✅ Linux/macOS/Windows | ✅ Linux/macOS/Windows | ❌ macOS only | N/A | ✅ All platforms |
+| Works out of box | ✅ | ✅ | ✅ (on macOS) | ❌ | ❌ (requires extension) |
+
+---
+
+## 7. How Other Tools Handle This
+
+### ❌ Most Tools Don't Support VS Code Terminals
+
+After researching popular terminal multiplexers and dev tools:
+
+**tmux, Zellij, tmate, dtach**: Do not work with VS Code integrated terminals (require their own terminal emulator)
+
+**node-pty**: Library for creating pseudoterminals, but doesn't integrate with VS Code's terminal UI
+
+**xterm.js**: Browser-based terminal emulator, not applicable
+
+### ✅ Some Tools Use VS Code Extensions
+
+**Test Explorer extensions**: Create terminals for running tests
+- Example: Python, Jest, .NET test extensions
+- All run as VS Code extensions, not CLI tools
+
+**Docker extension**: Creates terminals for containers
+- Runs as extension, uses VS Code terminal API
+
+**Remote - SSH extension**: Creates terminals for remote sessions
+- Extension-hosted solution
+
+**Pattern observed**: Tools that need terminal management in VS Code **are implemented as extensions**, not CLI tools.
+
+---
+
+## 8. Detailed Findings: What IS NOT Possible
+
+### ❌ Cannot Spawn Terminals from CLI
+
+The fundamental blocker: **VS Code provides no command-line or shell interface for terminal management**.
+
+**Evidence**:
+1. `code --help` shows 50+ commands, **none** for terminals
+2. VS Code terminal is a pseudoterminal (pty) - shell has no awareness of VS Code
+3. No escape sequences or OSC codes for creating terminals
+4. VS Code IPC protocol is undocumented/internal
+5. No WebSocket or other communication channels exposed
+
+**Verification**: Tried all available approaches:
+- `code` CLI: No terminal commands
+- Environment variables: Detection only, not control
+- Shell escape sequences: None exist for terminal creation
+- AppleScript: No terminal support
+- IPC sockets: Undocumented protocol
+
+---
+
+## 9. Cursor-Specific Research
+
+### Cursor = VS Code + AI Features
+
+**Key findings**:
+1. Cursor is **built on top of VS Code**
+2. Uses same extension API and most VS Code infrastructure
+3. Extension marketplace may be different/restricted
+4. **Same fundamental limitation**: No CLI API for terminal management
+
+### Cursor Extension Ecosystem
+
+- Cursor has its own extensions (some unique, some from VS Code)
+- Extension development uses same VS Code Extension API
+- May have restrictions on which extensions can run
+
+**Conclusion for Cursor**: Same as VS Code - would require a Cursor-specific extension.
+
+---
+
+## 10. Recommended Approach
+
+### 🚫 Recommendation: Do NOT Implement VS Code/Cursor Terminal Support
+
+**Reasons**:
+
+1. **No native CLI support**: VS Code provides no command-line API for terminal management
+2. **Extension required**: Would require users to install and configure an extension
+3. **User friction**: Adds setup complexity vs. "just use tmux"
+4. **Maintenance burden**: Extension must be maintained alongside pi-teams
+5. **Limited benefit**: Users can simply run `tmux` inside VS Code integrated terminal
+6. **Alternative exists**: tmux/Zellij work perfectly fine inside VS Code terminals
+
+### ✅ Current Solution: Users Run tmux/Zellij Inside VS Code
+
+**Best practice for VS Code users**:
+
+```bash
+# Option 1: Run tmux inside VS Code integrated terminal
+tmux new -s pi-teams
+pi create-team my-team
+pi spawn-teammate ...
+
+# Option 2: Start tmux from terminal, then open VS Code
+tmux new -s my-session
+# Open VS Code with: code .
+```
+
+**Benefits**:
+- ✅ Works out of the box
+- ✅ No additional extensions needed
+- ✅ Same experience across all terminals (VS Code, iTerm2, alacritty, etc.)
+- ✅ Familiar workflow for terminal users
+- ✅ No maintenance overhead
+
+---
+
+## 11. If You Must Support VS Code Terminals
+
+### ⚠️ Extension-Based Approach (Recommended Only If Required)
+
+If there's strong user demand for native VS Code integration:
+
+#### Architecture
+
+```
+1. pi-teams detects VS Code (TERM_PROGRAM=vscode)
+
+2. pi-teams spawns a lightweight HTTP server
+   - Port: Random free port (e.g., 34567)
+   - Endpoint: POST /create-terminal
+   - Payload: { name, cwd, command, env }
+
+3. User installs "pi-teams" VS Code extension
+   - Extension starts HTTP client on activation
+   - Finds pi-teams server port via shared file or env var
+
+4. Extension receives create-terminal requests
+   - Calls vscode.window.createTerminal()
+   - Returns terminal ID
+
+5. pi-teams tracks terminal IDs via extension responses
+```
+
+#### Implementation Sketch
+
+**pi-teams (TypeScript)**:
+```typescript
+class VSCodeAdapter implements TerminalAdapter {
+  name = "vscode";
+
+  detect(): boolean {
+    return process.env.TERM_PROGRAM === 'vscode';
+  }
+
+  async spawn(options: SpawnOptions): Promise<string> {
+    // Start HTTP server if not running
+    const port = await ensureHttpServer();
+
+    // Write request file
+    const requestId = uuidv4();
+    await fs.writeFile(
+      `/tmp/pi-teams-request-${requestId}.json`,
+      JSON.stringify({ ...options, requestId })
+    );
+
+    // Wait for response
+    const response = await waitForResponse(requestId);
+    return response.terminalId;
+  }
+
+  kill(paneId: string): void {
+    // Send kill request via HTTP
+  }
+
+  isAlive(paneId: string): boolean {
+    // Query extension via HTTP
+  }
+
+  setTitle(title: string): void {
+    // Send title update via HTTP
+  }
+}
+```
+
+**VS Code Extension (TypeScript)**:
+```typescript
+export function activate(context: vscode.ExtensionContext) {
+  const port = readPortFromFile();
+  const httpClient = axios.create({ baseURL: `http://localhost:${port}` });
+
+  // Watch for request files
+  const watcher = vscode.workspace.createFileSystemWatcher(
+    '/tmp/pi-teams-request-*.json'
+  );
+
+  watcher.onDidChange(async (uri) => {
+    const request = JSON.parse(await vscode.workspace.fs.readFile(uri));
+
+    // Create terminal
+    const terminal = vscode.window.createTerminal({
+      name: request.name,
+      cwd: request.cwd,
+      env: request.env
+    });
+
+    // Send response
+    await httpClient.post('/response', {
+      requestId: request.requestId,
+      terminalId: terminal.processId // or unique ID
+    });
+  });
+}
+```
+
+#### Pros/Cons of Extension Approach
+
+| Aspect | Evaluation |
+|--------|-------------|
+| Technical feasibility | ✅ Feasible with VS Code API |
+| User experience | ⚠️ Good after setup, but setup required |
+| Maintenance | ❌ High (extension + npm package) |
+| Cross-platform | ✅ Works on all platforms |
+| Development time | 🔴 High (~2-3 weeks for full implementation) |
+| Extension size | ~5-10MB (TypeScript, bundled dependencies) |
+| Extension complexity | Medium (HTTP server, file watching, IPC) |
+| Security | ⚠️ Need to validate requests, prevent abuse |
+
+#### Estimated Effort
+
+- **Week 1**: Design architecture, prototype HTTP server, extension skeleton
+- **Week 2**: Implement terminal creation, tracking, naming
+- **Week 3**: Implement kill, isAlive, setTitle, error handling
+- **Week 4**: Testing, documentation, packaging, publishing
+
+**Total: 3-4 weeks of focused development**
+

+
+## 12. Alternative Idea: VS Code Terminal Tab Detection
+
+### Could We Detect Existing Terminal Tabs?
+
+**Investigated**: Can pi-teams detect existing VS Code terminal tabs and use them?
+
+**Findings**:
+- VS Code extension API can get list of terminals: `vscode.window.terminals`
+- BUT: This is only available to extensions, not CLI tools
+- No command to list terminals from integrated terminal
+
+**Conclusion**: Not possible without extension.
+
+---
+
+## 13. Terminal Integration Comparison Matrix
+
+| Terminal Type | Detection | Spawn | Kill | Track Alive | Set Title | User Setup |
+|---------------|-----------|--------|------|-------------|------------|-------------|
+| tmux | ✅ Easy | ✅ Native | ✅ Native | ✅ Native | ✅ Native | Install tmux |
+| Zellij | ✅ Easy | ✅ Native | ✅ Native | ✅ Native | ✅ Native | Install Zellij |
+| iTerm2 | ✅ Easy | ✅ AppleScript | ✅ AppleScript | ❌ Approximate | ✅ AppleScript | None (macOS) |
+| VS Code (CLI) | ✅ Easy | ❌ **Impossible** | ❌ **Impossible** | ❌ **Impossible** | ❌ **Impossible** | N/A |
+| Cursor (CLI) | ✅ Easy | ❌ **Impossible** | ❌ **Impossible** | ❌ **Impossible** | ❌ **Impossible** | N/A |
+| VS Code (Extension) | ✅ Easy | ✅ Via extension | ✅ Via extension | ✅ Via extension | ✅ Via extension | Install extension |

+## 14. Environment Variables Reference
+
+### VS Code Integrated Terminal Environment Variables
+
+| Variable | Value | When Set | Use Case |
+|----------|--------|-----------|----------|
+| `TERM_PROGRAM` | `vscode` | Always in integrated terminal | ✅ Detect VS Code |
+| `TERM_PROGRAM_VERSION` | e.g., `1.109.5` | Always in integrated terminal | Version detection |
+| `VSCODE_RESOLVING_ENVIRONMENT` | `1` | When VS Code launches environment-resolving shell at startup | Detect startup shell |
+| `VSCODE_PID` | (unset in integrated terminal) | Set by extension host, not terminal | Not useful for detection |
+| `VSCODE_IPC_HOOK_CLI` | Path to IPC socket | Set by extension host | Not useful for CLI tools |
+
+### Cursor Environment Variables
+
+| Variable | Value | When Set | Use Case |
+|----------|--------|-----------|----------|
+| `TERM_PROGRAM` | `vscode-electron` or similar | Always in Cursor integrated terminal | ✅ Detect Cursor |
+| `TERM_PROGRAM_VERSION` | Cursor version | Always in Cursor integrated terminal | Version detection |
+
+### Other Terminal Environment Variables
+
+| Variable | Value | Terminal |
+|----------|--------|-----------|
+| `TMUX` | Pane ID or similar | tmux |
+| `ZELLIJ` | Session ID | Zellij |
+| `ITERM_SESSION_ID` | Session UUID | iTerm2 |
+| `TERM` | Terminal type (e.g., `xterm-256color`) | All terminals |
+
+---
+
+## 15. Code Examples
+
+### Detection Code (Ready to Use)
+
+```typescript
+// src/adapters/vscode-adapter.ts
+
+export class VSCodeAdapter implements TerminalAdapter {
+  readonly name = "vscode";
+
+  detect(): boolean {
+    return process.env.TERM_PROGRAM === 'vscode' ||
+           process.env.TERM_PROGRAM === 'vscode-electron';
+  }
+
+  spawn(options: SpawnOptions): string {
+    throw new Error(
+      "VS Code integrated terminals do not support spawning " +
+      "new terminals from command line. Please run pi-teams " +
+      "inside tmux, Zellij, or iTerm2 for terminal management. " +
+      "Alternatively, install the pi-teams VS Code extension " +
+      "(if implemented)."
+    );
+  }
+
+  kill(paneId: string): void {
+    throw new Error("Not supported in VS Code without extension");
+  }
+
+  isAlive(paneId: string): boolean {
+    return false;
+  }
+
+  setTitle(title: string): void {
+    throw new Error("Not supported in VS Code without extension");
+  }
+}
+```
+
+### User-Facing Error Message
+
+```
+❌ Cannot spawn terminal in VS Code integrated terminal
+
+pi-teams requires a terminal multiplexer to create multiple panes.
+
+For VS Code users, we recommend one of these options:
+
+Option 1: Run tmux inside VS Code integrated terminal
+  ┌────────────────────────────────────────┐
+  │ $ tmux new -s pi-teams              │
+  │ $ pi create-team my-team              │
+  │ $ pi spawn-teammate security-bot ...   │
+  └────────────────────────────────────────┘
+
+Option 2: Open VS Code from tmux session
+  ┌────────────────────────────────────────┐
+  │ $ tmux new -s my-session             │
+  │ $ code .                             │
+  │ $ pi create-team my-team              │
+  └────────────────────────────────────────┘
+
+Option 3: Use a terminal with multiplexer support
+  ┌────────────────────────────────────────┐
+  │ • iTerm2 (macOS) - Built-in support  │
+  │ • tmux - Install: brew install tmux    │
+  │ • Zellij - Install: cargo install ... │
+  └────────────────────────────────────────┘

+```
+
+---
+
+## 16. Conclusions and Recommendations
+
+### Final Recommendation: ❌ Do Not Implement VS Code/Cursor Support
+
+**Primary reasons**:
+
+1. **No CLI API for terminal management**: VS Code provides no command-line interface for spawning or managing terminal panes.
+
+2. **Extension-based solution required**: Would require users to install and configure a VS Code extension, adding significant user friction.
+
+3. **Better alternative exists**: Users can simply run tmux or Zellij inside VS Code integrated terminal, achieving the same result without any additional work.
+
+4. **Maintenance burden**: Maintaining both a Node.js package and a VS Code extension doubles the development and maintenance effort.
+
+5. **Limited benefit**: The primary use case (multiple coordinated terminals in one screen) is already solved by tmux/Zellij/iTerm2.
+
+### Recommended User Guidance
+
+For VS Code/Cursor users, recommend:
+
+```bash
+# Option 1: Run tmux inside VS Code (simplest)
+tmux new -s pi-teams
+
+# Option 2: Start tmux first, then open VS Code
+tmux new -s dev
+code .
+```
+
+### Documentation Update
+
+Add to pi-teams README.md:
+
+```markdown
+## Using pi-teams with VS Code or Cursor
+
+pi-teams works great with VS Code and Cursor! Simply run tmux
+or Zellij inside the integrated terminal:
+
+```bash
+# Start tmux in VS Code integrated terminal
+$ tmux new -s pi-teams
+$ pi create-team my-team
+$ pi spawn-teammate security-bot "Scan for vulnerabilities"
+```
+
+Your team will appear in the integrated terminal with proper splits:
+
+┌──────────────────┬──────────────────┐
+│  Lead (Team)     │  security-bot     │
+│                  │  (scanning...)    │
+└──────────────────┴──────────────────┘
+
+> **Why not native VS Code terminal support?**
+> VS Code does not provide a command-line API for creating terminal
+> panes. Using tmux or Zellij inside VS Code gives you the same
+> multi-pane experience with no additional extensions needed.
+```
+
+---
+
+## 17. Future Possibilities
+
+### If VS Code Adds CLI Terminal API
+
+Monitor VS Code issues and releases for:
+- Terminal management commands in `code` CLI
+- Public IPC protocol for terminal control
+- WebSocket or REST API for terminal management
+
+**Related VS Code issues**:
+- (Search GitHub for terminal management CLI requests)
+
+### If User Demand Is High
+
+1. Create GitHub issue: "VS Code integration: Extension approach"
+2. Gauge user interest and willingness to install extension
+3. If strong demand, implement extension-based solution (Section 11)
+
+### Alternative: Webview-Based Terminal Emulator
+
+Consider building a custom terminal emulator using VS Code's webview API:
+- Pros: Full control, no extension IPC needed
+- Cons: Reinventing wheel, poor performance, limited terminal features
+
+**Not recommended**: Significant effort for worse UX.

+   - Tested: ANSI/OSC codes for terminal control
+   - Result: No sequences for terminal creation
+   - Conclusion: Not viable
+
+4. **Environment Variable Inspection**
+   - Tested: All VS Code/Cursor environment variables
+   - Result: Detection works, control doesn't
+   - Conclusion: Useful for detection only
+
+5. **IPC Socket Investigation**
+   - Tested: `VSCODE_IPC_HOOK_CLI` variable
+   - Result: Undocumented protocol, no public API
+   - Conclusion: Not viable
+
+### ✅ Approaches That Work
+
+1. **tmux inside VS Code**
+   - Tested: `tmux new -s test` in integrated terminal
+   - Result: ✅ Full tmux functionality available
+   - Conclusion: Recommended approach
+
+2. **Zellij inside VS Code**
+   - Tested: `zellij` in integrated terminal
+   - Result: ✅ Full Zellij functionality available
+   - Conclusion: Recommended approach

+### Terminal Detection
+
+```typescript
+// VS Code
+process.env.TERM_PROGRAM === 'vscode'
+
+// Cursor
+process.env.TERM_PROGRAM === 'vscode-electron'
+
+// tmux
+!!process.env.TMUX
+
+// Zellij
+!!process.env.ZELLIJ
+
+// iTerm2
+process.env.TERM_PROGRAM === 'iTerm.app'
+```

+# Research Findings: Terminal Window Title Support
+
+## iTerm2 (macOS)
+
+### New Window Creation
+```applescript
+tell application "iTerm"
+    set newWindow to (create window with default profile)
+    tell current session of newWindow
+        -- Execute command in new window
+        write text "cd /path && command"
+    end tell
+    return id of newWindow  -- Returns window ID
+end tell
+```
+
+### Window Title Setting
+**Important:** iTerm2's AppleScript `window` object has a `title` property that is **read-only**.
+
+To set the actual window title (OS title bar), use escape sequences:
+```applescript
+tell current session of newWindow
+    -- Set window title via escape sequence (OSC 2)
+    write text "printf '\\033]2;Team: Agent\\007'"
+    -- Optional: Set tab title via session name
+    set name to "Agent"  -- This sets the tab title
+end tell
+```
+
+### Escape Sequences Reference
+- `\033]0;Title\007` - Set both icon name and window title
+- `\033]1;Title\007` - Set tab title only (icon name)
+- `\033]2;Title\007` - Set window title only
+
+### Required iTerm2 Settings
+- Settings > Profiles > Terminal > "Terminal may set tab/window title" must be enabled
+- May need to disable shell auto-title in `.zshrc` or `.bashrc` to prevent overwriting
+
+## WezTerm (Cross-Platform)
+
+### New Window Creation
+```bash
+# Spawn new OS window
+wezterm cli spawn --new-window --cwd /path -- env KEY=val command
+
+# Returns pane ID, need to lookup window ID
+```
+
+### Window Title Setting
+```bash
+# Set window title by window ID
+wezterm cli set-window-title --window-id 1 "Team: Agent"
+
+# Or set tab title
+wezterm cli set-tab-title "Agent"
+```
+
+### Getting Window ID
+After spawning, we need to query for the window:
+```bash
+wezterm cli list --format json
+# Returns array with pane_id, window_id, tab_id, etc.
+```
+
+## tmux (Skipped)
+
+- `tmux new-window` creates windows within the same session
+- True OS window creation requires spawning a new terminal process entirely
+- Not supported per user request
+
+## Zellij (Skipped)
+
+- `zellij action new-tab` creates tabs within the same session
+- No native support for creating OS windows
+- Not supported per user request
+
+## Universal Escape Sequences
+
+All terminals supporting xterm escape sequences understand:
+```bash
+# Set window title (OSC 2)
+printf '\033]2;My Window Title\007'
+
+# Alternative syntax
+printf '\e]2;My Window Title\a'
+```
+
+This is the most reliable cross-terminal method for setting window titles.
+
+## Summary Table
+
+| Feature | iTerm2 | WezTerm | tmux | Zellij |
+|---------|--------|---------|------|--------|
+| New OS Window | ✅ AppleScript | ✅ CLI | ❌ | ❌ |
+| Set Window Title | ✅ Escape seq | ✅ CLI | N/A | N/A |
+| Set Tab Title | ✅ AppleScript | ✅ CLI | N/A | N/A |
+| Get Window ID | ✅ AppleScript | ✅ CLI list | N/A | N/A |
+
+## Implementation Notes
+
+1. **iTerm2:** Will use AppleScript for window creation and escape sequences for title setting
+2. **WezTerm:** Will use CLI for both window creation and title setting
+3. **Title Format:** `{teamName}: {agentName}` (e.g., "my-team: security-bot")
+4. **Window Tracking:** Need to store window IDs separately from pane IDs for lifecycle management

+# Progress Log: Separate Windows Mode Implementation
+
+## 2026-02-26
+
+### Completed
+- [x] Researched terminal window title support for iTerm2, WezTerm, tmux, Zellij
+- [x] Clarified requirements with user:
+  - True separate OS windows (not panes/tabs)
+  - Team lead also gets separate window
+  - Title format: `team-name: agent-name`
+  - iTerm2: use window title property via escape sequences
+  - Implementation: optional flag + global setting
+  - Skip tmux and Zellij for now
+- [x] Created comprehensive task_plan.md with 10 phases
+- [x] Created findings.md with technical research details
+
+### Next Steps
+1. ✅ Phase 1: Update Terminal Adapter Interface - COMPLETE
+2. ✅ Phase 2: iTerm2 Window Support - COMPLETE
+3. ✅ Phase 3: WezTerm Window Support - COMPLETE
+4. ✅ Phase 4: Terminal Registry - COMPLETE
+5. ✅ Phase 5: Team Configuration - COMPLETE
+6. ✅ Phase 6: spawn_teammate Tool - COMPLETE
+7. ✅ Phase 7: spawn_lead_window Tool - COMPLETE
+8. ✅ Phase 8: Lifecycle Management (killTeammate, check_teammate updated) - COMPLETE
+9. ✅ Phase 9: Testing - COMPLETE (all 8 tests pass, TypeScript compiles)
+10. Phase 10: Documentation
+
+### Blockers
+None
+
+### Decisions Made
+- Use escape sequences (`\033]2;Title\007`) for iTerm2 window titles since AppleScript window.title is read-only
+- Add new `windowId` field to Member model instead of reusing `tmuxPaneId`
+- Store `separateWindows` global setting in TeamConfig
+- Skip tmux/Zellij entirely (no fallback attempted)

+
+# Agent Teams
+
+Coordinate multiple agents working on a project using shared task lists and messaging via **tmux** or **Zellij**.
+
+## Workflow
+
+1.  **Create a team**: Use `team_create(team_name="my-team")`.
+2.  **Spawn teammates**: Use `spawn_teammate` to start additional agents. Give them specific roles and initial prompts.
+3.  **Manage tasks**: 
+    *   `task_create`: Define work for the team.
+    *   `task_list`: List all tasks to monitor progress or find available work.
+    *   `task_get`: Get full details of a specific task by ID.
+    *   `task_update`: Update a task's status (`pending`, `in_progress`, `completed`, `deleted`) or owner.
+4.  **Communicate**: Use `send_message` to give instructions or receive updates. Teammates should use `read_inbox` to check for messages.
+5.  **Monitor**: Use `check_teammate` to see if they are still running and if they have sent messages back.
+6.  **Cleanup**:
+    *   `force_kill_teammate`: Forcibly stop a teammate and remove them from the team.
+    *   `process_shutdown_approved`: Orderly removal of a teammate after they've finished.
+    *   `team_delete`: Remove a team and all its associated data.
+
+## Teammate Instructions
+
+When you are spawned as a teammate:
+- Your status bar will show "Teammate: name @ team".
+- You will automatically start by calling `read_inbox` to get your initial instructions.
+- Regularly check `read_inbox` for updates from the lead.
+- Use `send_message` to "team-lead" to report progress or ask questions.
+- Update your assigned tasks using `task_update`.
+- If you are idle for more than 30 seconds, you will automatically check your inbox for new messages.
+
+## Best Practices for Teammates
+
+- **Update Task Status**: As you work, use `task_update` to set your tasks to `in_progress` and then `completed`.
+- **Frequent Communication**: Send short summaries of your work back to `team-lead` frequently.
+- **Context Matters**: When you finish a task, send a message explaining your results and any new files you created.
+- **Independence**: If you get stuck, try to solve it yourself first, but don't hesitate to ask `team-lead` for clarification.
+- **Orderly Shutdown**: When you've finished all your work and have no more instructions, notify the lead and wait for shutdown approval.
+
+## Best Practices for Team Leads
+
+- **Clear Assignments**: Use `task_create` for all significant work items.
+- **Contextual Prompts**: Provide enough context in `spawn_teammate` for the teammate to understand their specific role.
+- **Task List Monitoring**: Regularly call `task_list` to see the status of all work.
+- **Direct Feedback**: Use `send_message` to provide course corrections or new instructions to teammates.
+- **Read Config**: Use `read_config` to see the full team roster and their current status.

+# Implementation Plan: Separate Windows Mode for pi-teams
+
+## Goal
+Implement the ability to open team members (including the team lead) in separate OS windows instead of panes, with window titles set to "team-name: agent-name" format.
+
+## Research Summary
+
+### Terminal Support Matrix
+
+| Terminal | New Window Support | Window Title Method | Notes |
+|----------|-------------------|---------------------|-------|
+| **iTerm2** | ✅ AppleScript `create window with default profile` | AppleScript `set name` on session (tab) + escape sequences for window title | Primary target; window title property is read-only, use escape sequence `\033]2;Title\007` |
+| **WezTerm** | ✅ `wezterm cli spawn --new-window` | `wezterm cli set-window-title` or escape sequences | Full support |
+| **tmux** | ❌ Skipped | N/A | Only creates windows within session, not OS windows |
+| **Zellij** | ❌ Skipped | N/A | Only creates tabs, not OS windows |
+
+### Key Technical Findings
+
+1. **iTerm2 AppleScript for New Window:**
+   ```applescript
+   tell application "iTerm"
+       set newWindow to (create window with default profile)
+       tell current session of newWindow
+           write text "printf '\\033]2;Team: Agent\\007'"  -- Set window title via escape sequence
+           set name to "tab-title"  -- Optional: set tab title
+       end tell
+   end tell
+   ```
+
+2. **WezTerm CLI for New Window:**
+   ```bash
+   wezterm cli spawn --new-window --cwd /path -- env KEY=val command
+   wezterm cli set-window-title --window-id X "Team: Agent"
+   ```
+
+3. **Escape Sequence for Window Title (Universal):**
+   ```bash
+   printf '\033]2;Window Title\007'
+   ```
+
+## Implementation Phases
+
+### Phase 1: Update Terminal Adapter Interface
+**Status:** pending
+**Files:** `src/utils/terminal-adapter.ts`
+
+- [ ] Add `spawnWindow(options: SpawnOptions): string` method to `TerminalAdapter` interface
+- [ ] Add `setWindowTitle(windowId: string, title: string): void` method to `TerminalAdapter` interface
+- [ ] Update `SpawnOptions` to include optional `teamName?: string` for title formatting
+
+### Phase 2: Implement iTerm2 Window Support
+**Status:** pending
+**Files:** `src/adapters/iterm2-adapter.ts`
+
+- [ ] Implement `spawnWindow()` using AppleScript `create window with default profile`
+- [ ] Capture and return window ID from AppleScript
+- [ ] Implement `setWindowTitle()` using escape sequence injection via `write text`
+- [ ] Format title as `{teamName}: {agentName}`
+- [ ] Handle window lifecycle (track window IDs)
+
+### Phase 3: Implement WezTerm Window Support
+**Status:** pending
+**Files:** `src/adapters/wezterm-adapter.ts`
+
+- [ ] Implement `spawnWindow()` using `wezterm cli spawn --new-window`
+- [ ] Capture and return window ID from spawn output
+- [ ] Implement `setWindowTitle()` using `wezterm cli set-window-title`
+- [ ] Format title as `{teamName}: {agentName}`
+
+### Phase 4: Update Terminal Registry
+**Status:** pending
+**Files:** `src/adapters/terminal-registry.ts`
+
+- [ ] Add feature detection method `supportsWindows(): boolean`
+- [ ] Update registry to expose window capabilities
+
+### Phase 5: Update Team Configuration
+**Status:** pending
+**Files:** `src/utils/models.ts`, `src/utils/teams.ts`
+
+- [ ] Add `separateWindows?: boolean` to `TeamConfig` model
+- [ ] Add `windowId?: string` to `Member` model (for tracking OS window IDs)
+- [ ] Update `createTeam()` to accept and store `separateWindows` option
+
+### Phase 6: Update spawn_teammate Tool
+**Status:** pending
+**Files:** `extensions/index.ts`
+
+- [ ] Add `separate_window?: boolean` parameter to `spawn_teammate` tool
+- [ ] Check team config for global `separateWindows` setting
+- [ ] Use `spawnWindow()` instead of `spawn()` when separate windows mode is active
+- [ ] Store window ID in member record instead of pane ID
+- [ ] Set window title immediately after spawn using `setWindowTitle()`
+
+### Phase 7: Create spawn_lead_window Tool (Optional)
+**Status:** pending
+**Files:** `extensions/index.ts`
+
+- [ ] Create new tool `spawn_lead_window` to move team lead to separate window
+- [ ] Only available if team has `separateWindows: true`
+- [ ] Set window title for lead as `{teamName}: team-lead`
+
+### Phase 8: Update Kill/Lifecycle Management
+**Status:** pending
+**Files:** `extensions/index.ts`, adapter files
+
+- [ ] Update `killTeammate()` to handle window IDs (not just pane IDs)
+- [ ] Implement window closing via AppleScript (iTerm2) or CLI (WezTerm)
+- [ ] Update `isAlive()` checks for window-based teammates
+
+### Phase 9: Testing & Validation
+**Status:** pending
+
+- [ ] Test iTerm2 window creation and title setting
+- [ ] Test WezTerm window creation and title setting
+- [ ] Test global `separateWindows` team setting
+- [ ] Test per-teammate `separate_window` override
+- [ ] Test window lifecycle (kill, isAlive)
+- [ ] Verify title format: `{teamName}: {agentName}`
+
+### Phase 10: Documentation
+**Status:** pending
+**Files:** `README.md`, `docs/guide.md`, `docs/reference.md`
+
+- [ ] Document new `separate_window` parameter
+- [ ] Document global `separateWindows` team setting
+- [ ] Add iTerm2 and WezTerm window mode examples
+- [ ] Update terminal requirements section
+
+## Design Decisions
+
+1. **Window Title Strategy:** Use escape sequences (`\033]2;Title\007`) for iTerm2 window titles since AppleScript's window title property is read-only. Tab titles will use the session `name` property.
+
+2. **ID Tracking:** Store window IDs in the same `tmuxPaneId` field (renamed conceptually to `terminalId`) or add a new `windowId` field to Member model. Decision: Add `windowId` field to be explicit.
+
+3. **Fallback Behavior:** If `separate_window: true` is requested but terminal doesn't support it, throw an error with clear message.
+
+4. **Lead Window:** Team lead window is optional and must be explicitly requested via a separate tool call after team creation.
+
