Extensions can now use async initialization, enabling:
- Dynamic imports (e.g., loading tools from external packages)
- Async setup (config fetching, service connections)
- Lazy-loaded dependencies
Changes:
- ExtensionFactory type now returns void | Promise<void>
- loadExtensionFromFactory is now async, returns Promise<LoadedExtension>
- All factory(api) calls are now awaited
Backwards compatible: sync extensions continue to work unchanged.
- ExtensionAPI: setModel(), getThinkingLevel(), setThinkingLevel() methods
- New preset.ts example with plan/implement presets for model/thinking/tools switching
- Export all UI components from pi-coding-agent for extension use
- docs/tui.md: Common Patterns section with copy-paste code for SelectList, BorderedLoader, SettingsList, setStatus, setWidget, setFooter
- docs/tui.md: Key Rules section for extension UI development
- docs/extensions.md: Exhaustive example links for all ExtensionAPI methods and events
- System prompt now references docs/tui.md for TUI development
Fixes#509, relates to #347
When OAuth refresh fails during model discovery, getApiKey() now returns
undefined instead of throwing. This allows the app to start and fall back
to other providers, so the user can /login to re-authenticate.
fixes#498
Adds sendUserMessage() to the extension API, allowing extensions to send
actual user messages (role: user) rather than custom messages. Unlike
sendMessage(), this always triggers a turn and behaves as if the user
typed the message.
- Add SendUserMessageHandler type and sendUserMessage() to ExtensionAPI
- Wire handler through loader, runner, and all modes
- Implement via prompt() with expandPromptTemplates: false
- Add send-user-message.ts example with /ask, /steer, /followup commands
- Document in extensions.md
fixes#483
Extensions can now replace the built-in footer with a custom component:
- setFooter(factory) replaces with custom component
- setFooter(undefined) restores built-in footer
Includes example extension demonstrating context usage display.
Closes#481
- Setting controls filtering at convertToLlm layer
- Images are always stored in session, filtered dynamically based on current setting
- Toggle mid-session works: LLM sees/doesn't see images already in session
- Fixed SettingsManager.save() to handle inMemory mode for all setters
Closes#492
- Setting controls filtering at convertToLlm layer (defense-in-depth)
- Images are always stored in session, filtered dynamically based on current setting
- Toggle mid-session works: LLM sees/doesn't see images already in session
- Fixed SettingsManager.save() to handle inMemory mode for all setters
Closes#492
- Add sessionId to StreamOptions for providers that support session-based caching
- OpenAI Codex provider uses sessionId for prompt_cache_key and routing headers
- Agent class now accepts and forwards sessionId to stream functions
- coding-agent passes session ID from SessionManager and updates on session changes
- Update ai package README with table of contents, OpenAI Codex OAuth docs, and env vars table
- Increase Codex instructions cache TTL from 15 minutes to 24 hours
- Add tests for sessionId forwarding in ai and agent packages
- Validate working directory exists before spawning to provide clear error message
- Add spawn error handler to prevent uncaught exceptions when shell not found or cwd invalid
- Add tests for both error scenarios
Without these fixes, spawn errors (e.g., ENOENT from missing cwd or shell) would
cause uncaught exceptions that crash the entire agent session instead of being
returned as clean tool errors.

* feat: add copy-link button to share viewer messages
Implements the feature requested in #437:
- Add a small link icon button that appears on hovering over user/assistant
messages in the share viewer
- Clicking the button copies a shareable URL to clipboard with visual feedback
- URL format: base?gistId&leafId=<active-leaf>&targetId=<message-id>
- When loading a URL with leafId and targetId params:
- Navigate to the specified leaf node
- Scroll to and briefly highlight the target message
This enables users to share links to specific messages within a session.
* fix: preserve gist ID format and add clipboard fallback
- Fix URL format to produce ?gistId&leafId=... instead of ?gistId=&leafId=...
(preserves the bare key format expected by the backend)
- Add execCommand fallback for clipboard copy on HTTP contexts where
navigator.clipboard is unavailable
Messages submitted during compaction are queued and delivered after
compaction completes, preserving steer vs follow-up behavior. Extension
commands execute immediately during compaction.

Windows Terminal does not support the Kitty keyboard protocol, so
Shift+Enter cannot be distinguished from Enter. Document that users
should use Ctrl+Enter for multi-line input instead.
- Add Windows Terminal note in Terminal Setup section
- Update Keyboard Shortcuts table with Windows note
- Show Windows-specific hint in /hotkeys command
- Remove per-thinking-level model variants (gpt-5.2-codex-high, etc.)
- Remove thinkingLevels from Model type
- Provider clamps reasoning effort internally
- Omit reasoning field when thinking is off
fixes#472
Only fall back to 256color for truly limited terminals (dumb, empty, linux).
Virtually all modern terminals support truecolor, no need to be conservative.
- Add LoginDialogComponent with proper borders (top/bottom DynamicBorder)
- Refactor all OAuth providers to use racing approach (browser callback vs manual paste)
- Add onEscape handler to Input component for cancellation
- Add abortable sleep for GitHub Copilot polling (instant cancel on Escape)
- Show OS-specific click hint (Cmd+click on macOS, Ctrl+click elsewhere)
- Clear content between login phases (fixes GitHub Copilot two-phase flow)
- Use InteractiveMode's showStatus/showError for result messages
- Reorder providers: Anthropic, ChatGPT, GitHub Copilot, Gemini CLI, Antigravity
Previously, users had to wait up to 60 seconds for the browser callback
to timeout before being prompted to paste the authorization code. This
was problematic for SSH/VPS sessions where the callback cannot work.
Now the paste input is shown immediately alongside the browser flow:
- Browser callback and manual paste race - whichever completes first wins
- Desktop users: browser callback succeeds, input is cleaned up
- SSH/VPS users: paste code immediately without waiting
Changes:
- Add cancelWait() to OAuth server for early termination of polling loop
- Add onManualCodeInput callback that races with browser callback
- Show paste input immediately in TUI for openai-codex provider
- Clean up input on success, error, or when browser callback wins

SettingsManager was created after extension loading, so extensions
defined in settings.json were never loaded. Move SettingsManager.create
before discoverAndLoadExtensions and merge settings extensions with
CLI --extension args.
- Accept ExtensionFactory[] for inline extensions (merged with discovery)
- Mark preloadedExtensions as @internal (CLI implementation detail)
- Update sdk.md with inline extension example
- Update CHANGELOG
- Auto-migrate commands/ to prompts/ on startup
- Warn if hooks/ or tools/ directories contain custom extensions
- Show deprecation warnings in interactive mode with keypress to continue
- Update CHANGELOG and docs with full migration guide
Breaking changes:
- Settings: 'hooks' and 'customTools' arrays replaced with 'extensions'
- CLI: '--hook' and '--tool' flags replaced with '--extension' / '-e'
- API: HookMessage renamed to CustomMessage, role 'hookMessage' to 'custom'
- API: FileSlashCommand renamed to PromptTemplate
- API: discoverSlashCommands() renamed to discoverPromptTemplates()
- Directories: commands/ renamed to prompts/ for prompt templates
Migration:
- Session version bumped to 3 (auto-migrates v2 sessions)
- Old 'hookMessage' role entries converted to 'custom'
Structural changes:
- src/core/hooks/ and src/core/custom-tools/ merged into src/core/extensions/
- src/core/slash-commands.ts renamed to src/core/prompt-templates.ts
- examples/hooks/ and examples/custom-tools/ merged into examples/extensions/
- docs/hooks.md and docs/custom-tools.md merged into docs/extensions.md
New test coverage:
- test/extensions-runner.test.ts (10 tests)
- test/extensions-discovery.test.ts (26 tests)
- test/prompt-templates.test.ts
Discovery rules:
1. extensions/*.ts or *.js - direct files
2. extensions/*/index.ts or index.js - subdirectory with index
3. extensions/*/package.json with pi field - load declared paths
No recursion beyond one level. Complex packages use package.json manifest.
Added PiManifest type for future theme/skill bundling support.
17 tests covering all discovery scenarios.
