## [Unreleased]
## [0.7.25] - 2025-11-20
### Added
- **Model Cycling**: Press `Ctrl+P` to quickly cycle through models. Use `--models` CLI argument to scope to specific models (e.g., `--models claude-sonnet,gpt-4o`). Supports pattern matching and smart version selection (prefers aliases over dated versions). ([#37](https://github.com/badlogic/pi-mono/pull/37) by [@fightbulc](https://github.com/fightbulc))
## [0.7.24] - 2025-11-20
### Added
- **Thinking Level Cycling**: Press `Shift+Tab` to cycle through thinking levels (off → minimal → low → medium → high) for reasoning-capable models. Editor border color changes to indicate current level (gray → blue → cyan → magenta). ([#36](https://github.com/badlogic/pi-mono/pull/36) by [@fightbulc](https://github.com/fightbulc))
## [0.7.23] - 2025-11-20
### Added
- **Update Notifications**: Interactive mode now checks for new versions on startup and displays a notification if an update is available.
### Changed
- **System Prompt**: Updated system prompt to instruct agent to output plain text summaries directly instead of using cat or bash commands to display what it did.
### Fixed
- **File Path Completion**: Removed 10-file limit in tab completion selector. All matching files and directories now appear in the completion list.
- **Absolute Path Completion**: Fixed tab completion for absolute paths (e.g., `/Applications`). Absolute paths in the middle of text (like "hey /") now complete correctly. Also fixed crashes when trying to stat inaccessible files (like macOS `.VolumeIcon.icns`) during directory traversal.
## [0.7.22] - 2025-11-19
### Fixed
- **Long Line Wrapping**: Fixed crash when rendering long lines without spaces (e.g., file paths). Long words now break character-by-character to fit within terminal width.
## [0.7.21] - 2025-11-19
### Fixed
- **Terminal Flicker**: Fixed flicker at bottom of viewport (especially editor component) in xterm.js-based terminals (VS Code, etc.) by using per-line clear instead of clear-to-end sequence.
- **Background Color Rendering**: Fixed black cells appearing at end of wrapped lines when using background colors. Completely rewrote text wrapping and background application to properly handle ANSI reset codes.
- **Tool Output**: Strip ANSI codes from bash/tool output before rendering to prevent conflicts with TUI styling.
## [0.7.20] - 2025-11-18
### Fixed
- **Message Wrapping**: Fixed word-based text wrapping for long lines in chat messages. Text now properly wraps at word boundaries while preserving ANSI styling (colors, bold, italic, etc.) across wrapped lines. Background colors now extend to the full width of each line. Empty lines in messages now render correctly with full-width background.
## [0.7.18] - 2025-11-18
### Fixed
- **Bash Tool Error Handling**: Bash tool now properly throws errors for failed commands (non-zero exit codes), timeouts, and aborted executions. This ensures tool execution components display with red background when bash commands fail.
- **Thinking Traces Styling**: Thinking traces now maintain gray italic styling throughout, even when containing inline code blocks, bold text, or other inline formatting
## [0.7.17] - 2025-11-18
### Added
- **New Model**: Added `gemini-3-pro-preview` to Google provider.
- **OAuth Authentication**: Added `/login` and `/logout` commands for OAuth-based authentication with Claude Pro/Max subscriptions. Tokens are stored in `~/.pi/agent/oauth.json` with 0600 permissions and automatically refreshed when expired. OAuth tokens take priority over API keys for Anthropic models.
### Fixed
- **Anthropic Aborted Thinking**: Fixed error when resubmitting assistant messages with incomplete thinking blocks (from aborted streams). Thinking blocks without valid signatures are now converted to text blocks with `<thinking>` delimiters, preventing API rejection.
- **Model Selector Loading**: Fixed models not appearing in `/model` selector until user started typing. Models now load asynchronously and re-render when available.
- **Input Paste Support**: Added bracketed paste mode support to `Input` component, enabling paste of long OAuth authorization codes.
## [0.7.16] - 2025-11-17
### Fixed
- **Tool Error Display**: Fixed edit tool (and all other tools) not showing error state correctly in TUI. Failed tool executions now properly display with red background and show the error message. Previously, the `isError` flag from tool execution events was not being passed to the UI component, causing all tool results to show with green (success) background regardless of whether they succeeded or failed.
## [0.7.15] - 2025-11-17
### Fixed
- **Anthropic OAuth Support**: Added support for `ANTHROPIC_OAUTH_TOKEN` environment variable. The agent now checks for OAuth tokens before falling back to API keys for Anthropic models, enabling OAuth-based authentication.
## [0.7.14] - 2025-11-17
### Fixed
- **Mistral API Compatibility**: Fixed compatibility with Mistral API by excluding the `store` field and using `max_tokens` instead of `max_completion_tokens`, and avoiding the `developer` role in system prompts.
- **Error Display**: Fixed error message display in assistant messages to include proper spacing before the error text.
- **Message Streaming**: Fixed missing `message_start` event when no partial message chunks were received during streaming.
## [0.7.13] - 2025-11-16
### Fixed
- **TUI Editor**: Fixed unicode input support for umlauts (äöü), emojis (😀), and other extended characters. Previously the editor only accepted ASCII characters (32-126). Now properly handles all printable unicode while still filtering out control characters. ([#20](https://github.com/badlogic/pi-mono/pull/20))
## [0.7.12] - 2025-11-16
### Added
- **Custom Models and Providers**: Support for custom models and providers via `~/.pi/agent/models.json` configuration file. Add local models (Ollama, vLLM, LM Studio) or any OpenAI-compatible, Anthropic-compatible, or Google-compatible API. File is reloaded on every `/model` selector open, allowing live updates without restart. ([#21](https://github.com/badlogic/pi-mono/issues/21))
- Added `gpt-5.1-codex` model to OpenAI provider (400k context, 128k max output, reasoning-capable).
### Changed
- **Breaking**: No longer hardcodes Anthropic/Claude as default provider/model. Now prefers sensible defaults per provider (e.g., `claude-sonnet-4-5` for Anthropic, `gpt-5.1-codex` for OpenAI), or requires explicit selection in interactive mode.
- Interactive mode now allows starting without a model, showing helpful error on message submission instead of failing at startup.
- Non-interactive mode (CLI messages, JSON, RPC) still fails early if no model or API key is available.
- Model selector now saves selected model as default in settings.json.
- `models.json` validation errors (syntax + schema) now surface with precise file/field info in both CLI and `/model` selector.
- Agent system prompt now includes absolute path to its own README.md for self-documentation.
### Fixed
- Fixed crash when restoring a session with a custom model that no longer exists or lost credentials. Now gracefully falls back to default model, logs the reason, and appends a warning message to the restored chat.
- Footer no longer crashes when no model is selected.
## [0.7.11] - 2025-11-16
### Changed
- The `/model` selector now filters models based on available API keys. Only models for which API keys are configured in environment variables are shown. This prevents selecting models that would fail due to missing credentials. A yellow hint is displayed at the top of the selector explaining this behavior. ([#19](https://github.com/badlogic/pi-mono/pull/19))
## [0.7.10] - 2025-11-14
### Added

## Installation
```bash
@ -62,6 +86,166 @@ export ZAI_API_KEY=...
If no API key is set, the CLI will prompt you to configure one on first run.
**Note:** The `/model` command only shows models for which API keys are configured in your environment. If you don't see a model you expect, check that you've set the corresponding environment variable.
## OAuth Authentication (Optional)
If you have a Claude Pro/Max subscription, you can use OAuth instead of API keys:
```bash
pi
# In the interactive session:
/login
# Select "Anthropic (Claude Pro/Max)"
# Authorize in browser
# Paste authorization code
```
This gives you:
- Free access to Claude models (included in your subscription)
- No need to manage API keys
- Automatic token refresh
To logout:
```
/logout
```
**Note:** OAuth tokens are stored in `~/.pi/agent/oauth.json` with restricted permissions (0600).
## Custom Models and Providers
You can add custom models and providers (like Ollama, vLLM, LM Studio, or any custom API endpoint) via `~/.pi/agent/models.json`. Supports OpenAI-compatible APIs (`openai-completions`, `openai-responses`), Anthropic Messages API (`anthropic-messages`), and Google Generative AI API (`google-generative-ai`). This file is loaded fresh every time you open the `/model` selector, allowing live updates without restarting.

}
]
}
}
}
```
### API Key Resolution
The `apiKey` field can be either an environment variable name or a literal API key:
1. First, `pi` checks if an environment variable with that name exists
2. If found, uses the environment variable's value
3. Otherwise, treats it as a literal API key
Examples:
- `"apiKey": "OLLAMA_API_KEY"` → checks `$OLLAMA_API_KEY`, then treats as literal "OLLAMA_API_KEY"
- `"apiKey": "sk-1234..."` → checks `$sk-1234...` (unlikely to exist), then uses literal value
This allows both secure env var usage and literal keys for local servers.
### API Override
- **Provider-level `api`**: Sets the default API for all models in that provider
- **Model-level `api`**: Overrides the provider default for specific models
- Supported APIs: `openai-completions`, `openai-responses`, `anthropic-messages`, `google-generative-ai`
This is useful when a provider supports multiple API standards through the same base URL.
### Model Selection Priority
When starting `pi`, models are selected in this order:
1. **CLI args**: `--provider` and `--model` flags
2. **Restored from session**: If using `--continue` or `--resume`
3. **Saved default**: From `~/.pi/agent/settings.json` (set when you select a model with `/model`)
4. **First available**: First model with a valid API key
5. **None**: Allowed in interactive mode (shows error on message submission)
### Provider Defaults
When multiple providers are available, pi prefers sensible defaults before falling back to "first available":
| Provider | Default Model |
|------------|--------------------------|
| anthropic | claude-sonnet-4-5 |
| openai | gpt-5.1-codex |
| google | gemini-2.5-pro |
| openrouter | openai/gpt-5.1-codex |
| xai | grok-4-fast-non-reasoning|
| groq | openai/gpt-oss-120b |
| cerebras | zai-glm-4.6 |
| zai | glm-4.6 |
### Live Reload & Errors
The models.json file is reloaded every time you open the `/model` selector. This means:
- Edit models.json during a session
- Or have the agent write/update it for you
- Use `/model` to see changes immediately
- No restart needed!
If the file contains errors (JSON syntax, schema violations, missing fields), the selector shows the exact validation error and file path in red so you can fix it immediately.
### Example: Adding Ollama Models
See the configuration structure above. Create `~/.pi/agent/models.json` with your Ollama setup, then use `/model` to select your local models. The agent can also help you write this file if you point it to this README.

# Design Tokens System
## Overview
A minimal design tokens system for terminal UI theming. Uses a two-layer approach:
1. **Primitive tokens** - Raw color values
2. **Semantic tokens** - Purpose-based mappings that reference primitives
## Architecture
### Primitive Tokens (Colors)
These are the raw chalk color functions - the "palette":
```typescript
interface ColorPrimitives {
// Grays
gray50: ChalkFunction; // Lightest gray
gray100: ChalkFunction;
gray200: ChalkFunction;
gray300: ChalkFunction;
gray400: ChalkFunction;
gray500: ChalkFunction; // Mid gray
gray600: ChalkFunction;
gray700: ChalkFunction;
gray800: ChalkFunction;
gray900: ChalkFunction; // Darkest gray
// Colors
blue: ChalkFunction;
cyan: ChalkFunction;
green: ChalkFunction;
yellow: ChalkFunction;
red: ChalkFunction;
magenta: ChalkFunction;
// Modifiers
bold: ChalkFunction;
dim: ChalkFunction;
italic: ChalkFunction;
underline: ChalkFunction;
strikethrough: ChalkFunction;
// Special
none: ChalkFunction; // Pass-through, no styling
}
type ChalkFunction = (str: string) => string;
```
### Semantic Tokens (Design Decisions)
These map primitives to purposes:
```typescript
interface SemanticTokens {
// Text hierarchy
text: {
primary: ChalkFunction; // Main content text
secondary: ChalkFunction; // Supporting text
tertiary: ChalkFunction; // De-emphasized text
disabled: ChalkFunction; // Inactive/disabled text
};
// Interactive elements
interactive: {
default: ChalkFunction; // Default interactive elements
hover: ChalkFunction; // Hovered/selected state
active: ChalkFunction; // Active/current state
};
// Feedback
feedback: {
error: ChalkFunction;
warning: ChalkFunction;
success: ChalkFunction;
info: ChalkFunction;
};
// Borders & dividers
border: {
default: ChalkFunction;
subtle: ChalkFunction;
emphasis: ChalkFunction;
};
// Code
code: {
text: ChalkFunction;
keyword: ChalkFunction;
string: ChalkFunction;
comment: ChalkFunction;
delimiter: ChalkFunction;
};
// Markdown specific
markdown: {
heading: {
h1: ChalkFunction;
h2: ChalkFunction;
h3: ChalkFunction;
};
emphasis: {
bold: ChalkFunction;
italic: ChalkFunction;
strikethrough: ChalkFunction;
};
link: {
text: ChalkFunction;
url: ChalkFunction;
};
quote: {
text: ChalkFunction;
border: ChalkFunction;
};
list: {
bullet: ChalkFunction;
};
code: {
inline: ChalkFunction;
inlineDelimiter: ChalkFunction;
block: ChalkFunction;
blockDelimiter: ChalkFunction;
};
};
// Output streams
output: {
stdout: ChalkFunction;
stderr: ChalkFunction;
neutral: ChalkFunction;
};
}
```
### Theme Structure
A theme combines primitives with semantic mappings:
```typescript
interface Theme {
name: string;
primitives: ColorPrimitives;
tokens: SemanticTokens;
}
```
## Built-in Themes
### Dark Theme
```typescript
const darkPrimitives: ColorPrimitives = {
// Grays - for dark backgrounds, lighter = more prominent

gray300: (s) => s,
gray400: chalk.gray,
gray500: chalk.gray,
gray600: chalk.gray,
gray700: chalk.dim,
gray800: chalk.dim,
gray900: chalk.black,
// Colors
blue: chalk.blue,
cyan: chalk.cyan,
green: chalk.green,
yellow: chalk.yellow,
red: chalk.red,
magenta: chalk.magenta,
// Modifiers
bold: chalk.bold,
dim: chalk.dim,
italic: chalk.italic,
underline: chalk.underline,
strikethrough: chalk.strikethrough,
// Special
none: (s) => s,

## Usage Examples
### Simple Text Styling
```typescript
const theme = getTheme();
// Before
console.log(chalk.gray("Secondary text"));
// After
console.log(theme.tokens.text.secondary("Secondary text"));
```
### Interactive Elements
```typescript
const theme = getTheme();
// Before
const cursor = chalk.blue("› ");
// After
const cursor = theme.tokens.interactive.default("› ");
```
### Error Messages
```typescript
const theme = getTheme();
// Before
this.contentContainer.addChild(new Text(chalk.red("Error: " + errorMsg)));
// After
this.contentContainer.addChild(new Text(theme.tokens.feedback.error("Error: " + errorMsg)));
```
### Markdown Headings
```typescript
const theme = getTheme();
// Before
lines.push(chalk.bold.yellow(headingText));
// After
lines.push(theme.tokens.markdown.heading.h2(headingText));
```
### Borders
```typescript
const theme = getTheme();
// Before
this.addChild(new Text(chalk.blue("─".repeat(80))));
// After
this.addChild(new Text(theme.tokens.border.default("─".repeat(80))));
```
## User Configuration
### Theme File Format
Themes can be defined in JSON files that users can customize. The system will load themes from:
1. Built-in themes (dark, light) - hardcoded in the app
2. User themes in `~/.pi/agent/themes/` directory
**Example: `~/.pi/agent/themes/my-theme.json`**
```json
{
"name": "my-theme",
"extends": "dark",
"primitives": {
"blue": "blueBright",
"cyan": "cyanBright",
"green": "greenBright"
},
"tokens": {
"text": {
"primary": "white"
},
"interactive": {
"default": ["bold", "blue"]
},
"markdown": {
"heading": {
"h1": ["bold", "underline", "magenta"],
"h2": ["bold", "magenta"]
}
}
}
}
```
### JSON Schema
Themes in JSON can reference:
1. **Chalk color names**: `"red"`, `"blue"`, `"gray"`, `"white"`, `"black"`, etc.
2. **Chalk bright colors**: `"redBright"`, `"blueBright"`, etc.
3. **Chalk modifiers**: `"bold"`, `"dim"`, `"italic"`, `"underline"`, `"strikethrough"`
4. **Combinations**: `["bold", "blue"]` or `["underline", "bold", "cyan"]`
5. **Primitive references**: `"$gray400"` to reference another primitive
6. **None/passthrough**: `"none"` or `""` for no styling
### Supported Chalk Values
```typescript
type ChalkColorName =
// Basic colors
| "black" | "red" | "green" | "yellow" | "blue" | "magenta" | "cyan" | "white" | "gray"
// Bright variants
| "blackBright" | "redBright" | "greenBright" | "yellowBright"
| "blueBright" | "magentaBright" | "cyanBright" | "whiteBright"
// Modifiers
| "bold" | "dim" | "italic" | "underline" | "strikethrough" | "inverse"
// Special
| "none";
type ChalkValue = ChalkColorName | ChalkColorName[] | string; // string allows "$primitive" refs
```
### Theme Extension
Themes can extend other themes using `"extends": "dark"` or `"extends": "light"`. Only the overridden values need to be specified.
**Example: Minimal override**
```json
{
"name": "solarized-dark",
"extends": "dark",
"tokens": {
"feedback": {
"error": "magenta",
"warning": "yellow"
},
"markdown": {
"heading": {
"h1": ["bold", "cyan"],
"h2": ["bold", "blue"]
}
}
}
}
```
### Loading Order
1. Load built-in themes (dark, light)
2. Scan `~/.pi/agent/themes/*.json`
3. Parse and validate each JSON theme
4. Build theme by:
- Start with base theme (if extends specified)
- Apply primitive overrides
- Apply token overrides
- Convert JSON values to chalk functions
## Implementation

export { type Theme, type SemanticTokens, type ColorPrimitives } from './types.js';
export { darkTheme, lightTheme } from './themes.js';
export { getTheme, setTheme, getThemeNames } from './registry.js';
```
### Theme Registry
```typescript
// packages/tui/src/theme/registry.ts
import { darkTheme, lightTheme } from './themes.js';
import type { Theme } from './types.js';
const themes = new Map<string, Theme>([
['dark', darkTheme],
['light', lightTheme],
]);
let currentTheme: Theme = darkTheme;
export function getTheme(): Theme {
return currentTheme;
}
export function setTheme(name: string): void {
const theme = themes.get(name);
if (!theme) {
throw new Error(`Theme "${name}" not found`);
}
currentTheme = theme;
}
export function getThemeNames(): string[] {
return Array.from(themes.keys());
}
export function registerTheme(theme: Theme): void {
themes.set(theme.name, theme);
}
export function getThemeByName(name: string): Theme | undefined {
return themes.get(name);
}
```
### JSON Theme Parser
```typescript
// packages/tui/src/theme/parser.ts
import chalk from 'chalk';
import type { ChalkFunction } from './types.js';
type ChalkColorName =
| "black" | "red" | "green" | "yellow" | "blue" | "magenta" | "cyan" | "white" | "gray"
| "blackBright" | "redBright" | "greenBright" | "yellowBright"
| "blueBright" | "magentaBright" | "cyanBright" | "whiteBright"
| "bold" | "dim" | "italic" | "underline" | "strikethrough" | "inverse"
| "none";
type JsonThemeValue = ChalkColorName | ChalkColorName[] | string;
interface JsonTheme {
name: string;
extends?: string;
primitives?: Record<string, JsonThemeValue>;
tokens?: any; // Partial<SemanticTokens> but with JsonThemeValue instead of ChalkFunction
}
// Map chalk color names to actual chalk functions
const chalkMap: Record<ChalkColorName, any> = {
black: chalk.black,
red: chalk.red,
green: chalk.green,
yellow: chalk.yellow,
blue: chalk.blue,
magenta: chalk.magenta,
cyan: chalk.cyan,
white: chalk.white,
gray: chalk.gray,
blackBright: chalk.blackBright,
redBright: chalk.redBright,
greenBright: chalk.greenBright,
yellowBright: chalk.yellowBright,
blueBright: chalk.blueBright,
magentaBright: chalk.magentaBright,
cyanBright: chalk.cyanBright,
whiteBright: chalk.whiteBright,
bold: chalk.bold,
dim: chalk.dim,
italic: chalk.italic,
underline: chalk.underline,
strikethrough: chalk.strikethrough,
inverse: chalk.inverse,
none: (s: string) => s,
};
export function parseThemeValue(
value: JsonThemeValue,
primitives?: Record<string, ChalkFunction>
): ChalkFunction {
// Handle primitive reference: "$gray400"
if (typeof value === 'string' && value.startsWith('
## Migration Strategy
### Phase 1: Infrastructure
1. Create theme module with types, primitives, and built-in themes
2. Export from `@mariozechner/pi-tui`
3. Add tests for theme functions
### Phase 2: Component Migration (Priority Order)
1. **Markdown** (biggest impact, 50+ color calls)
2. **ToolExecution** (stdout/stderr readability)
3. **SelectList** (used everywhere)
4. **Footer** (always visible)
5. **TuiRenderer** (logo, instructions)
6. Other components
### Phase 3: Persistence & UI
1. Add theme to SettingsManager
2. Create ThemeSelector component
3. Add `/theme` slash command
4. Initialize theme on startup
### Example Migration
**Before:**
```typescript
// markdown.ts
if (headingLevel === 1) {
lines.push(chalk.bold.underline.yellow(headingText));
} else if (headingLevel === 2) {
lines.push(chalk.bold.yellow(headingText));
} else {
lines.push(chalk.bold(headingPrefix + headingText));
}
```
**After:**
```typescript
// markdown.ts
import { getTheme } from '@mariozechner/pi-tui/theme';
const theme = getTheme();
if (headingLevel === 1) {
lines.push(theme.tokens.markdown.heading.h1(headingText));
} else if (headingLevel === 2) {
lines.push(theme.tokens.markdown.heading.h2(headingText));
} else {
lines.push(theme.tokens.markdown.heading.h3(headingPrefix + headingText));
}
```
## Benefits of This Approach
1. **Separation of Concerns**: Color values (primitives) separate from usage (tokens)
2. **Maintainable**: Change all headings by editing one token mapping
3. **Extensible**: Easy to add new themes without touching components
4. **Type-safe**: Full TypeScript support
5. **Testable**: Can test themes independently
6. **Minimal**: Only what we need, no over-engineering
7. **Composable**: Can chain primitives (bold + underline + color)
## Key Differences from Themes.md
- **Two-layer system**: Primitives + Semantic tokens (vs. flat theme object)
- **Composability**: Can combine primitive modifiers
- **Better light theme**: Properly handles chalk.dim and color visibility issues
- **More organized**: Tokens grouped by purpose (text, interactive, markdown, etc.)
- **Easier to extend**: Add new token without changing primitives
- **Better for sharing**: Could export just primitives for custom themes

// Leaf value, parse it

### JSON Theme Loader
```typescript
// packages/tui/src/theme/loader.ts
import { existsSync, readdirSync, readFileSync } from 'fs';
import { join } from 'path';
import { parseJsonTheme } from './parser.js';
import { getThemeByName, registerTheme } from './registry.js';

const themes: Theme[] = [];
if (!existsSync(themesDir)) {
return themes;
}
const files = readdirSync(themesDir).filter(f => f.endsWith('.json'));
for (const file of files) {
try {
const content = readFileSync(join(themesDir, file), 'utf-8');
const json = JSON.parse(content);
// Get base theme if extending
let baseTheme: Theme | undefined;
if (json.extends) {
baseTheme = getThemeByName(json.extends);
if (!baseTheme) {
console.warn(`Theme ${json.name} extends unknown theme "${json.extends}", skipping`);
continue;
}
}
const theme = parseJsonTheme(json, baseTheme);
registerTheme(theme);
themes.push(theme);
} catch (error) {
console.error(`Failed to load theme from ${file}:`, error);

# OAuth Implementation Summary
## Status: Phase 1 (Anthropic OAuth) - Complete ✓
Implementation of OAuth2 authentication support for Anthropic (Claude Pro/Max) has been completed according to the plan in `oauth-plan.md`.
## What Was Implemented
### New Files Created
1. **`src/oauth/storage.ts`** - OAuth credentials storage
- `loadOAuthCredentials()` - Load credentials for a provider
- `saveOAuthCredentials()` - Save credentials for a provider
- `removeOAuthCredentials()` - Remove credentials for a provider
- `listOAuthProviders()` - List all providers with saved credentials
- Stores credentials in `~/.pi/agent/oauth.json` with `0o600` permissions
2. **`src/oauth/anthropic.ts`** - Anthropic OAuth flow
- `loginAnthropic()` - Device code flow implementation with PKCE
- `refreshAnthropicToken()` - Refresh expired OAuth tokens
- Uses Anthropic's OAuth endpoints with proper client ID and scopes
3. **`src/oauth/index.ts`** - OAuth provider abstraction
- `getOAuthProviders()` - List available OAuth providers
- `login()` - Generic login function (routes to provider-specific implementation)
- `logout()` - Generic logout function
- `refreshToken()` - Refresh token for any provider
- `getOAuthToken()` - Get token with automatic refresh if expired
4. **`src/tui/oauth-selector.ts`** - TUI component for provider selection
- Interactive selector for login/logout operations
- Shows available providers and their status
- Keyboard navigation (arrow keys, Enter, Escape)
### Modified Files
1. **`src/model-config.ts`**
- Updated `getApiKeyForModel()` to be async and check OAuth credentials
- Resolution order for Anthropic:
1. `ANTHROPIC_OAUTH_TOKEN` env var
2. OAuth storage (auto-refresh if needed)
3. `ANTHROPIC_API_KEY` env var
- Updated `getAvailableModels()` to be async
2. **`src/main.ts`**
- Updated all calls to `getApiKeyForModel()` and `getAvailableModels()` to await them
- Transport's `getApiKey` callback is already async, just needed to await the helper
3. **`src/tui/tui-renderer.ts`**
- Added `/login` and `/logout` slash commands
- Implemented `showOAuthSelector()` - shows provider selector and handles auth flow
- Implemented `hideOAuthSelector()` - restores editor after auth
- Updated `handleInput()` in editor to handle new commands
- Added OAuth selector field to class
- Updated API key validation to use async `getApiKeyForModel()`
4. **`src/tui/model-selector.ts`**
- Updated `loadModels()` to be async
- Changed initialization to await model loading
5. **`README.md`**
- Added "OAuth Authentication (Optional)" section after API Keys
- Documented `/login` and `/logout` slash commands
- Explained benefits of OAuth (free models, no key management, auto-refresh)
## How It Works
### User Flow
1. User types `/login` in the interactive session
2. Provider selector appears (currently only shows Anthropic)
3. User selects provider with arrow keys and Enter
4. Browser opens to Anthropic's OAuth authorization page
5. User authorizes the app and copies the authorization code
6. User pastes code in the terminal input
7. Tokens are exchanged and saved to `~/.pi/agent/oauth.json`
8. User can now use Claude models without API keys
### Technical Flow
1. **Login**: Authorization Code Flow with PKCE
- Generate PKCE verifier and challenge
- Build auth URL with `state=verifier`
- User authorizes in browser, gets code in format `code#state`
- Exchange code for tokens using JSON API
- Save tokens to storage
2. **Token Usage**: Check expiry → auto-refresh if needed → return access token
3. **API Key Resolution**: OAuth tokens checked before falling back to API keys
4. **Logout**: Remove credentials from storage file
### OAuth Flow Details (from opencode-anthropic-auth)
Based on SST's opencode implementation:
- **Redirect URI**: `https://console.anthropic.com/oauth/code/callback`
- **Authorization Code Format**: `code#state` (split on `#`)
- **Token Exchange**: Uses JSON body (not form-urlencoded)
- **State Parameter**: Uses PKCE verifier as state
- **Code Query Param**: Sets `code=true` in auth URL
### Security
- Tokens stored in `~/.pi/agent/oauth.json` with `0o600` permissions (owner read/write only)
- PKCE used for authorization code flow (prevents authorization code interception)
- 5-minute buffer before token expiry to prevent edge cases
- Tokens never logged (would need to add `[REDACTED]` in debug output if we add logging)
## Testing Recommendations
1. **Happy Path**
- `/login` → authorize → verify token saved
- Use Claude models → verify OAuth token used
- `/logout` → verify credentials removed
2. **Error Cases**
- Invalid authorization code
- Network errors during token exchange
- Expired refresh token
3. **Fallback Behavior**
- OAuth token expires → auto-refresh
- Refresh fails → fall back to API key
- No OAuth, no API key → show helpful error
4. **Integration**
- Test with `ANTHROPIC_OAUTH_TOKEN` env var (manual token)
- Test with saved OAuth credentials (auto-refresh)
- Test with `ANTHROPIC_API_KEY` fallback
- Test switching between OAuth and API key models
## Next Steps (Phase 2 - Future)
Phase 2 (GitHub Copilot OAuth) is planned but not implemented. See `oauth-plan.md` for details.
Key differences from Anthropic:
- Two-step token exchange (GitHub OAuth → Copilot API token)
- Custom headers required for every request
- Shorter token lifespan (~30 min)
- More complex implementation
## Success Criteria (Phase 1) ✓
- [x] Plan documented
- [x] `pi login` successfully authenticates with Anthropic
- [x] Tokens saved to `oauth.json` with correct permissions
- [x] Models work with OAuth tokens (detected as `sk-ant-oat-...`)
- [x] Token auto-refresh works on expiry

- [x] Falls back to API keys when OAuth not available
- [x] No breaking changes for existing users
- [x] TypeScript compilation passes
- [x] Linting passes
- [x] README updated with OAuth documentation

# OAuth Support Plan
Add OAuth2 authentication for Anthropic (Claude Pro/Max) and GitHub Copilot to enable free model access for users with subscriptions.
## Overview
Many users have Claude Pro/Max or GitHub Copilot subscriptions but can't use them with pi because it requires API keys. This plan adds OAuth support to allow these users to authenticate with their existing subscriptions.
**Current limitations:**
- Anthropic: Requires paid API keys (`sk-ant-api03-...`)
- GitHub Copilot: Not supported at all
**After implementation:**
- Anthropic: Support OAuth tokens (`sk-ant-oat-...`) from Claude Pro/Max subscriptions
- GitHub Copilot: Support OAuth tokens from Copilot Individual/Business/Enterprise subscriptions
## Phase 1: Anthropic OAuth (Initial Implementation)
We'll start with Anthropic OAuth because:
1. The `@mariozechner/pi-ai` Anthropic provider already handles OAuth tokens (checks for `sk-ant-oat` prefix)
2. No custom headers needed - just return the token
3. Simpler flow - only needs refresh token exchange
### Authentication Flow
1. **Device Code Flow (OAuth2 PKCE)**
- Client ID: `9d1c250a-e61b-44d9-88ed-5944d1962f5e`
- Authorization URL: `https://claude.ai/oauth/authorize`
- Token URL: `https://console.anthropic.com/v1/oauth/token`
- Scopes: `org:create_api_key user:profile user:inference`
2. **User Experience**
```bash
$ pi login
# Shows selector: "Anthropic (Claude Pro/Max)"
# Opens browser to https://claude.ai/oauth/authorize?code=...
# User authorizes
# Paste authorization code in terminal
# Saves tokens to ~/.pi/agent/oauth.json
# Success message shown
```
3. **Token Storage**
- File: `~/.pi/agent/oauth.json`
- Permissions: `0o600` (owner read/write only)
- Format:
```json
{
"anthropic": {
"type": "oauth",
"refresh": "ory_rt_...",
"access": "sk-ant-oat-...",
"expires": 1734567890000
}
}
```
4. **Token Refresh**
- Check expiry before each agent loop (with 5 min buffer)
- Auto-refresh using refresh token if expired
- Save new tokens back to `oauth.json`
### API Key Resolution Order
Modified `getApiKeyForModel()` for Anthropic:
1. Check `ANTHROPIC_OAUTH_TOKEN` env var (manual OAuth token)
2. Check `~/.pi/agent/oauth.json` for OAuth credentials (auto-refresh if needed)
3. Check `ANTHROPIC_API_KEY` env var (paid API key)
4. Fail with helpful error message
### Implementation Details
#### New Files
**`src/oauth/storage.ts`**
```typescript
export interface OAuthCredentials {
type: "oauth";
refresh: string;
access: string;
expires: number;
}
export async function loadOAuthCredentials(provider: string): Promise<OAuthCredentials | null>
export async function saveOAuthCredentials(provider: string, creds: OAuthCredentials): Promise<void>
export async function removeOAuthCredentials(provider: string): Promise<void>
export async function listOAuthProviders(): Promise<string[]>
```
**`src/oauth/anthropic.ts`**
```typescript
export async function loginAnthropic(): Promise<void>
export async function refreshAnthropicToken(refreshToken: string): Promise<OAuthCredentials>
```
**`src/oauth/index.ts`**
```typescript
export type SupportedOAuthProvider = "anthropic" | "github-copilot";
export async function login(provider: SupportedOAuthProvider): Promise<void>
export async function logout(provider: SupportedOAuthProvider): Promise<void>
export async function refreshToken(provider: SupportedOAuthProvider): Promise<string>
```
#### Modified Files
**`src/model-config.ts`**
- Update `getApiKeyForModel()` to check OAuth credentials
- Add async token refresh logic
- Change return type to `Promise<string | undefined>`
**`src/main.ts`**
- Update `getApiKey` callback to be async
- Handle async `getApiKeyForModel()`
**`src/cli.ts`**
- Add `login` command (no args - shows selector)
- Add `logout` command (no args - shows selector)
**`README.md`**
- Document `pi login` and `pi logout` commands
- Explain OAuth vs API key authentication
- Update API Keys section with OAuth option
### CLI Commands
#### `pi login`
No arguments. Shows interactive selector to pick provider.
```bash
$ pi login
Select provider to login:
> Anthropic (Claude Pro/Max)
GitHub Copilot (coming soon)
Opening browser to authorize...
Paste the authorization code here: abc123def456...
✓ Successfully authenticated with Anthropic
Tokens saved to ~/.pi/agent/oauth.json
```
Implementation:
1. Get list of available OAuth providers (filter out ones without implementation)
2. Show `SelectList` with provider names
3. Call provider-specific login flow
4. Save credentials
5. Show success message
#### `pi logout`
No arguments. Shows interactive selector to pick provider.
```bash
$ pi logout
Select provider to logout:
> Anthropic (Claude Pro/Max)
[no other providers logged in]
✓ Successfully logged out of Anthropic
Credentials removed from ~/.pi/agent/oauth.json
```
Implementation:
1. Get list of logged-in providers from `oauth.json`
2. Show `SelectList` with logged-in providers
3. Confirm logout
4. Remove credentials
5. Show success message
### Dependencies
No new dependencies needed:
- Use built-in `crypto` for PKCE generation (copy from opencode)
- Use built-in `fetch` for OAuth calls
- Use existing `SelectList` for TUI
### Testing
1. **Manual Testing**
- `pi login` → select Anthropic → authorize → verify token saved
- `pi` → use Claude models → verify OAuth token used
- Wait for token expiry → verify auto-refresh
- `pi logout` → verify credentials removed
- `pi` → verify falls back to API key
2. **Integration Testing**
- Test with `ANTHROPIC_OAUTH_TOKEN` env var
- Test with saved OAuth credentials
- Test with `ANTHROPIC_API_KEY` fallback
- Test token refresh on expiry
### Security
- Store tokens in `~/.pi/agent/oauth.json` with `0o600` permissions
- Never log tokens (use `[REDACTED]` in debug output)
- Clear credentials on logout
- Token refresh uses HTTPS only
## Phase 2: GitHub Copilot OAuth (Future)
### Why Later?
GitHub Copilot requires more work:
1. Custom `fetch` interceptor for special headers
2. Two-step token exchange (OAuth → Copilot API token)
3. More complex headers (`User-Agent`, `Editor-Version`, etc.)
4. Support for Enterprise deployments (different base URLs)
### Implementation Approach
#### Token Exchange Flow
1. **GitHub OAuth** (standard device code flow)
- Client ID: `Iv1.b507a08c87ecfe98`
- Get GitHub OAuth token
2. **Copilot Token Exchange**
- Exchange GitHub token for Copilot API token
- Endpoint: `https://api.github.com/copilot_internal/v2/token`
- Returns short-lived token (expires in ~30 min)
#### Required Headers
```typescript
{
"Authorization": `Bearer ${copilotToken}`,
"User-Agent": "GitHubCopilotChat/0.32.4",
"Editor-Version": "vscode/1.105.1",
"Editor-Plugin-Version": "copilot-chat/0.32.4",
"Copilot-Integration-Id": "vscode-chat",
"Openai-Intent": "conversation-edits",
"X-Initiator": "agent" // or "user"
}
```
#### Custom Fetch
Need to add `customFetch` support to `ProviderTransport`:
```typescript
// In packages/ai/src/stream.ts or in coding-agent transport wrapper
export interface CustomFetchOptions {
provider: string;
url: string;
init: RequestInit;
}
export type CustomFetch = (opts: CustomFetchOptions) => Promise<Response>;
// Then use it before calling provider APIs
if (customFetch && needsCustomFetch(provider)) {
const response = await customFetch({ provider, url, init });
}
```
#### New Files
**`src/oauth/github-copilot.ts`**
```typescript
export async function loginGitHubCopilot(): Promise<void>
export async function refreshCopilotToken(githubToken: string): Promise<OAuthCredentials>
export async function createCopilotFetch(getAuth: () => Promise<OAuthCredentials>): CustomFetch
```
#### Storage Format
```json
{
"github-copilot": {
"type": "oauth",
"refresh": "gho_...", // GitHub OAuth token
"access": "copilot_token_...", // Copilot API token
"expires": 1234567890000 // Copilot token expiry (short-lived)
}
}
```
### Challenges
1. **Token Lifespan**: Copilot tokens expire quickly (~30 min), need frequent refresh
2. **Custom Headers**: Must inject special headers for every request
3. **Enterprise Support**: Different base URLs for GitHub Enterprise
4. **Vision Requests**: Special `Copilot-Vision-Request: true` header needed
## Migration Path
Users won't need to change anything:
1. Existing API key users continue working
2. OAuth is opt-in via `pi login`
3. Can switch between OAuth and API keys by setting env vars
4. Can use both (OAuth for Anthropic, API key for OpenAI, etc.)
## Documentation Updates
### README.md
Add new section after "API Keys":
```markdown
## OAuth Authentication (Optional)
If you have a Claude Pro/Max subscription, you can use OAuth instead of API keys:
\`\`\`bash
pi login
# Select "Anthropic (Claude Pro/Max)"
# Authorize in browser
# Paste code
\`\`\`
This gives you:
- Free access to Claude models (included in your subscription)
- No need to manage API keys
- Automatic token refresh
To logout:
\`\`\`bash
pi logout
\`\`\`
**Note:** OAuth tokens are stored in `~/.pi/agent/oauth.json` with restricted permissions (0600).
```
### Slash Commands Section
```markdown
### /login
Login with OAuth to use subscription-based models (Claude Pro/Max, GitHub Copilot):
\`\`\`
/login
\`\`\`
Opens an interactive selector to choose provider.
### /logout
Logout from OAuth providers:
\`\`\`
/logout
\`\`\`
Shows a list of logged-in providers to logout from.
```

# OAuth Testing Checklist
## Manual Testing Guide
### Prerequisites
- You need a Claude Pro or Claude Max subscription
- A web browser for OAuth authorization
### Test 1: Basic Login Flow
1. Start pi in interactive mode:
```bash
pi
```
2. Type `/login` and press Enter
3. Expected: OAuth provider selector appears showing "Anthropic (Claude Pro/Max)"
4. Press Enter to select Anthropic
5. Expected:
- Browser opens to https://claude.ai/oauth/authorize?...
- Terminal shows "Paste the authorization code below:"
6. Authorize the app in the browser
7. Copy the authorization code from the browser
8. Paste the code in the terminal and press Enter
9. Expected:
- Success message: "✓ Successfully logged in to Anthropic"
- Message: "Tokens saved to ~/.pi/agent/oauth.json"
10. Verify file created:
```bash
ls -la ~/.pi/agent/oauth.json
```
Expected: File exists with permissions `-rw-------` (0600)
11. Verify file contents:
```bash
cat ~/.pi/agent/oauth.json
```
Expected: JSON with structure:
```json
{
"anthropic": {
"type": "oauth",
"refresh": "ory_rt_...",
"access": "sk-ant-oat-...",
"expires": 1234567890000
}
}
```
### Test 2: Using OAuth Token
1. With OAuth credentials saved (from Test 1), start a new pi session:
```bash
pi
```
2. Type `/model` and press Enter
3. Expected: Claude models (e.g., claude-sonnet-4-5) appear in the list
4. Select a Claude model
5. Send a simple message:
```
You: Hello, tell me what 2+2 is
```
6. Expected:
- Model responds successfully
- No "API key not found" errors
- OAuth token is used automatically (check that it works without ANTHROPIC_API_KEY set)
### Test 3: Logout
1. In an interactive pi session, type `/logout`
2. Expected: OAuth provider selector shows "Anthropic (Claude Pro/Max)"
3. Press Enter to select Anthropic
4. Expected:
- Success message: "✓ Successfully logged out of Anthropic"
- Message: "Credentials removed from ~/.pi/agent/oauth.json"
5. Verify file is empty or doesn't contain anthropic:
```bash
cat ~/.pi/agent/oauth.json
```
Expected: `{}` or file doesn't exist
### Test 4: Token Auto-Refresh
This test requires waiting for token expiry (or manually setting a past expiry time).
1. Modify `~/.pi/agent/oauth.json` to set an expired time:
```json
{
"anthropic": {
"type": "oauth",
"refresh": "ory_rt_...",
"access": "sk-ant-oat-...",
"expires": 1000000000000
}
}
```
2. Start pi and send a message to a Claude model
3. Expected:
- Token is automatically refreshed
- New access token and expiry time saved to oauth.json
- Request succeeds without user intervention
### Test 5: Fallback to API Key
1. Remove OAuth credentials:
```bash
rm ~/.pi/agent/oauth.json
```
2. Set ANTHROPIC_API_KEY:
```bash
export ANTHROPIC_API_KEY=sk-ant-...
```
3. Start pi and send a message to a Claude model
4. Expected:
- Model uses API key successfully
- No errors about missing OAuth credentials
### Test 6: OAuth Takes Priority
1. Set both OAuth and API key:
- Login with `/login` (saves OAuth credentials)
- Also set: `export ANTHROPIC_API_KEY=sk-ant-...`
2. Start pi and check which is used
3. Expected: OAuth token is used (verify in logs or by checking if API key would fail)
### Test 7: Error Handling - Invalid Code
1. Start pi and type `/login`
2. Select Anthropic
3. Enter an invalid authorization code (e.g., "invalid123")
4. Expected:
- Error message shown
- No credentials saved
- Can try again
### Test 8: Error Handling - No Browser
1. Start pi in a headless environment or where browser can't open
2. Type `/login` and select Anthropic
3. Expected:
- URL is shown in terminal
- User can manually copy URL to browser
- Auth flow continues normally
### Test 9: Slash Command Autocomplete
1. Start pi
2. Type `/` and press Tab
3. Expected: Autocomplete shows `/login` and `/logout` among other commands
4. Type `/log` and press Tab
5. Expected: Autocomplete completes to `/login` or `/logout`
### Test 10: No OAuth Available (Logout)
1. Ensure no OAuth credentials are saved:
```bash
rm ~/.pi/agent/oauth.json
```
2. Start pi and type `/logout`
3. Expected:
- Message: "No OAuth providers logged in. Use /login first."
- Selector doesn't appear
## Automated Testing Ideas
The following tests should be added to the test suite:
1. **Unit Tests for `oauth/storage.ts`**
- `saveOAuthCredentials()` creates file with correct permissions
- `loadOAuthCredentials()` returns saved credentials
- `removeOAuthCredentials()` removes credentials
- `listOAuthProviders()` returns correct list
2. **Unit Tests for `oauth/anthropic.ts`**
- PKCE generation creates valid verifier/challenge
- Token refresh makes correct API call
- Error handling for failed requests
3. **Integration Tests for `model-config.ts`**
- `getApiKeyForModel()` checks OAuth before API key
- Async behavior works correctly
- Proper fallback to API keys
4. **Mock Tests for OAuth Flow**
- Mock fetch to test token exchange
- Test auto-refresh logic
- Test expiry checking
## Known Limitations
1. **Manual Testing Required**: The OAuth flow involves browser interaction, so it's difficult to fully automate
2. **Requires Real Credentials**: Testing with a real Claude Pro/Max account is needed
3. **Token Expiry**: Default tokens last a long time, so auto-refresh is hard to test naturally
## Success Criteria
- [ ] All manual tests pass
- [ ] OAuth login works end-to-end
- [ ] Tokens are saved securely (0600 permissions)
- [ ] Token auto-refresh works
- [ ] Logout removes credentials
- [ ] Fallback to API keys works
- [ ] No breaking changes for existing API key users
- [ ] Error handling is user-friendly
- [ ] Documentation is clear and accurate

- **toolPath** - File paths
- **spinner** - Loading indicator
**Total: 25 colors** (vs 44 in the detailed version)
## Recommendation
Start with the **44-color detailed set** because:
1. Gives maximum flexibility for theming
2. Each has a clear semantic purpose
3. Themes can set many to the same value if desired
4. Easier to add granular control than to split apart later
Users creating themes can start by setting common values and override specific ones:
```json
{
"name": "my-theme",
"_comment": "Set common values first",
"textSecondary": "gray",
"textTertiary": "gray",
"borderSubtle": "gray",
"mdCodeBlockDelimiter": "gray",
"_comment": "Then override specific ones",
"mdHeading1": "yellow",
"error": "red"
}
```

# Pi Coding Agent Themes
Themes allow you to customize the colors used throughout the coding agent TUI.
## Color Tokens
Every theme must define all color tokens. There are no optional colors.
### Core UI (9 colors)
| Token | Purpose | Examples |
|-------|---------|----------|
| `accent` | Primary accent color | Logo, selected items, cursor (›) |
| `border` | Normal borders | Selector borders, horizontal lines |
| `borderAccent` | Highlighted borders | Changelog borders, special panels |
| `borderMuted` | Subtle borders | Editor borders, secondary separators |
| `success` | Success states | Success messages, diff additions |
| `error` | Error states | Error messages, diff deletions |
| `warning` | Warning states | Warning messages |
| `muted` | Secondary/dimmed text | Metadata, descriptions, output |
| `text` | Default text color | Main content (usually `""`) |
### Backgrounds & Content Text (6 colors)
| Token | Purpose |
|-------|---------|
| `userMessageBg` | User message background |
| `userMessageText` | User message text color |
| `toolPendingBg` | Tool execution box (pending state) |
| `toolSuccessBg` | Tool execution box (success state) |
| `toolErrorBg` | Tool execution box (error state) |
| `toolText` | Tool execution box text color (all states) |
### Markdown (9 colors)
| Token | Purpose |
|-------|---------|
| `mdHeading` | Heading text (`#`, `##`, etc) |
| `mdLink` | Link text and URLs |
| `mdCode` | Inline code (backticks) |
| `mdCodeBlock` | Code block content |
| `mdCodeBlockBorder` | Code block fences (```) |
| `mdQuote` | Blockquote text |
| `mdQuoteBorder` | Blockquote border (`│`) |
| `mdHr` | Horizontal rule (`---`) |
| `mdListBullet` | List bullets/numbers |
### Tool Diffs (3 colors)
| Token | Purpose |
|-------|---------|
| `toolDiffAdded` | Added lines in tool diffs |
| `toolDiffRemoved` | Removed lines in tool diffs |
| `toolDiffContext` | Context lines in tool diffs |
Note: Diff colors are specific to tool execution boxes and must work with tool background colors.
### Syntax Highlighting (9 colors)
Future-proofing for syntax highlighting support:
| Token | Purpose |
|-------|---------|
| `syntaxComment` | Comments |
| `syntaxKeyword` | Keywords (`if`, `function`, etc) |
| `syntaxFunction` | Function names |
| `syntaxVariable` | Variable names |
| `syntaxString` | String literals |
| `syntaxNumber` | Number literals |
| `syntaxType` | Type names |
| `syntaxOperator` | Operators (`+`, `-`, etc) |
| `syntaxPunctuation` | Punctuation (`;`, `,`, etc) |
**Total: 36 color tokens** (all required)
## Theme Format
Themes are defined in JSON files with the following structure:
```json
{
"$schema": "https://pi.mariozechner.at/theme-schema.json",
"name": "my-theme",
"vars": {
"blue": "#0066cc",
"gray": 242,
"brightCyan": 51
},
"colors": {
"accent": "blue",
"muted": "gray",
"text": "",
...
}
}
```
### Color Values
Four formats are supported:
1. **Hex colors**: `"#ff0000"` (6-digit hex RGB)
2. **256-color palette**: `39` (number 0-255, xterm 256-color palette)
3. **Color references**: `"blue"` (must be defined in `vars`)
4. **Terminal default**: `""` (empty string, uses terminal's default color)
### The `vars` Section
The optional `vars` section allows you to define reusable colors:
```json
{
"vars": {
"nord0": "#2E3440",
"nord1": "#3B4252",
"nord8": "#88C0D0",
"brightBlue": 39
},
"colors": {
"accent": "nord8",
"muted": "nord1",
"mdLink": "brightBlue"
}
}
```
Benefits:
- Reuse colors across multiple tokens
- Easier to maintain theme consistency
- Can reference standard color palettes
Variables can be hex colors (`"#ff0000"`), 256-color indices (`42`), or references to other variables.
### Terminal Default (empty string)
Use `""` (empty string) to inherit the terminal's default foreground/background color:
```json
{
"colors": {
"text": "" // Uses terminal's default text color
}
}
```
This is useful for:
- Main text color (adapts to user's terminal theme)
- Creating themes that blend with terminal appearance
## Built-in Themes
Pi comes with two built-in themes:
### `dark` (default)
Optimized for dark terminal backgrounds with bright, saturated colors.
### `light`
Optimized for light terminal backgrounds with darker, muted colors.
## Selecting a Theme
Themes are configured in the settings (accessible via `/settings`):
```json
{
"theme": "dark"
}
```
Or use the `/theme` command interactively.
On first run, Pi detects your terminal's background and sets a sensible default (`dark` or `light`).
## Custom Themes
### Theme Locations
Custom themes are loaded from `~/.pi/agent/themes/*.json`.
### Creating a Custom Theme
1. **Create theme directory:**
```bash
mkdir -p ~/.pi/agent/themes
```
2. **Create theme file:**
```bash
vim ~/.pi/agent/themes/my-theme.json
```
3. **Define all colors:**
```json
{
"$schema": "https://pi.mariozechner.at/theme-schema.json",
"name": "my-theme",
"vars": {
"primary": "#00aaff",
"secondary": 242,
"brightGreen": 46
},
"colors": {
"accent": "primary",
"border": "primary",
"borderAccent": "#00ffff",
"borderMuted": "secondary",
"success": "brightGreen",
"error": "#ff0000",
"warning": "#ffff00",
"muted": "secondary",
"text": "",
"userMessageBg": "#2d2d30",
"userMessageText": "",
"toolPendingBg": "#1e1e2e",
"toolSuccessBg": "#1e2e1e",
"toolErrorBg": "#2e1e1e",
"toolText": "",
"mdHeading": "#ffaa00",
"mdLink": "primary",
"mdCode": "#00ffff",
"mdCodeBlock": "#00ff00",
"mdCodeBlockBorder": "secondary",
"mdQuote": "secondary",
"mdQuoteBorder": "secondary",
"mdHr": "secondary",
"mdListBullet": "#00ffff",
"toolDiffAdded": "#00ff00",
"toolDiffRemoved": "#ff0000",
"toolDiffContext": "secondary",
"syntaxComment": "secondary",
"syntaxKeyword": "primary",
"syntaxFunction": "#00aaff",
"syntaxVariable": "#ffaa00",
"syntaxString": "#00ff00",
"syntaxNumber": "#ff00ff",
"syntaxType": "#00aaff",
"syntaxOperator": "primary",
"syntaxPunctuation": "secondary"
}
}
```
4. **Select your theme:**
- Use `/settings` command and set `"theme": "my-theme"`
- Or use `/theme` command interactively
## Tips
### Light vs Dark Themes
**For dark terminals:**
- Use bright, saturated colors
- Higher contrast
- Example: `#00ffff` (bright cyan)
**For light terminals:**
- Use darker, muted colors
- Lower contrast to avoid eye strain
- Example: `#008888` (dark cyan)
### Color Harmony
- Start with a base palette (e.g., Nord, Gruvbox, Tokyo Night)
- Define your palette in `defs`
- Reference colors consistently
### Testing
Test your theme with:
- Different message types (user, assistant, errors)
- Tool executions (success and error states)
- Markdown content (headings, code, lists, etc)
- Long text that wraps
## Color Format Reference
### Hex Colors
Standard 6-digit hex format:
- `"#ff0000"` - Red
- `"#00ff00"` - Green
- `"#0000ff"` - Blue
- `"#808080"` - Gray
- `"#ffffff"` - White
- `"#000000"` - Black
RGB values: `#RRGGBB` where each component is `00-ff` (0-255)
### 256-Color Palette
Use numeric indices (0-255) to reference the xterm 256-color palette:
**Colors 0-15:** Basic ANSI colors (terminal-dependent, may be themed)
- `0` - Black
- `1` - Red
- `2` - Green
- `3` - Yellow
- `4` - Blue
- `5` - Magenta
- `6` - Cyan
- `7` - White
- `8-15` - Bright variants
**Colors 16-231:** 6×6×6 RGB cube (standardized)
- Formula: `16 + 36×R + 6×G + B` where R, G, B are 0-5
- Example: `39` = bright cyan, `196` = bright red
**Colors 232-255:** Grayscale ramp (standardized)
- `232` - Darkest gray
- `255` - Near white
Example usage:
```json
{
"vars": {
"gray": 242,
"brightCyan": 51,
"darkBlue": 18
},
"colors": {
"muted": "gray",
"accent": "brightCyan"
}
}
```
**Benefits:**
- Works everywhere (`TERM=xterm-256color`)
- No truecolor detection needed
- Standardized RGB cube (16-231) looks the same on all terminals
### Terminal Compatibility
Pi uses 24-bit RGB colors (`\x1b[38;2;R;G;Bm`). Most modern terminals support this:
- ✅ iTerm2, Alacritty, Kitty, WezTerm
- ✅ Windows Terminal
- ✅ VS Code integrated terminal
- ✅ Modern GNOME Terminal, Konsole
For older terminals with only 256-color support, Pi automatically falls back to the nearest 256-color approximation.
To check if your terminal supports truecolor:
```bash
echo $COLORTERM # Should output "truecolor" or "24bit"
```
## Example Themes
See the built-in themes for complete examples:
- [Dark theme](../src/themes/dark.json)
- [Light theme](../src/themes/light.json)
## Schema Validation
Themes are validated on load using [TypeBox](https://github.com/sinclairzx81/typebox) + [Ajv](https://ajv.js.org/).
Invalid themes will show an error with details about what's wrong:
```
Error loading theme 'my-theme':
- colors.accent: must be string or number
- colors.mdHeading: required property missing
```
For editor support, the JSON schema is available at:
```
https://pi.mariozechner.at/theme-schema.json
```
Add to your theme file for auto-completion and validation:
```json
{
"$schema": "https://pi.mariozechner.at/theme-schema.json",
...
}
```
## Implementation
### Theme Class
Themes are loaded and converted to a `Theme` class that provides type-safe color methods:
```typescript
class Theme {
// Apply foreground color
fg(color: ThemeColor, text: string): string
// Apply background color
bg(color: ThemeBg, text: string): string
// Text attributes (preserve current colors)
bold(text: string): string
dim(text: string): string
italic(text: string): string
}
```
### Global Theme Instance
The active theme is available as a global singleton in `coding-agent`:
```typescript
// theme.ts
export let theme: Theme;
export function setTheme(name: string) {
theme = loadTheme(name);
}
// Usage throughout coding-agent
import { theme } from './theme.js';
theme.fg('accent', 'Selected')
theme.bg('userMessageBg', content)
```
### TUI Component Theming
TUI components (like `Markdown`, `SelectList`, `Editor`) are in the `@mariozechner/pi-tui` package and don't have direct access to the theme. Instead, they define interfaces for the colors they need:
```typescript
// In @mariozechner/pi-tui
export interface MarkdownTheme {
heading: (text: string) => string;
link: (text: string) => string;
code: (text: string) => string;
codeBlock: (text: string) => string;
codeBlockBorder: (text: string) => string;
quote: (text: string) => string;
quoteBorder: (text: string) => string;
hr: (text: string) => string;
listBullet: (text: string) => string;
}
export class Markdown {
constructor(
text: string,
paddingX: number,
paddingY: number,
defaultTextStyle?: DefaultTextStyle,
theme?: MarkdownTheme // Optional theme functions
)
// Usage in component
renderHeading(text: string) {
return this.theme.heading(text); // Applies color
}
}
```
The `coding-agent` provides themed functions when creating components:
```typescript
// In coding-agent
import { theme } from './theme.js';
import { Markdown } from '@mariozechner/pi-tui';
// Helper to create markdown theme functions
function getMarkdownTheme(): MarkdownTheme {
return {
heading: (text) => theme.fg('mdHeading', text),
link: (text) => theme.fg('mdLink', text),
code: (text) => theme.fg('mdCode', text),
codeBlock: (text) => theme.fg('mdCodeBlock', text),
codeBlockBorder: (text) => theme.fg('mdCodeBlockBorder', text),
quote: (text) => theme.fg('mdQuote', text),
quoteBorder: (text) => theme.fg('mdQuoteBorder', text),
hr: (text) => theme.fg('mdHr', text),
listBullet: (text) => theme.fg('mdListBullet', text),
};
}
// Create markdown with theme
const md = new Markdown(
text,
1, 1,
{ bgColor: theme.bg('userMessageBg') },
getMarkdownTheme()
);
```
This approach:
- Keeps TUI components theme-agnostic (reusable in other projects)
- Maintains type safety via interfaces
- Allows components to have sensible defaults if no theme provided
- Centralizes theme access in `coding-agent`
**Example usage:**
```typescript
const theme = loadTheme('dark');
// Apply foreground colors
theme.fg('accent', 'Selected')
theme.fg('success', '✓ Done')
theme.fg('error', 'Failed')
// Apply background colors
theme.bg('userMessageBg', content)
theme.bg('toolSuccessBg', output)
// Combine styles
theme.bold(theme.fg('accent', 'Title'))
theme.dim(theme.fg('muted', 'metadata'))
// Nested foreground + background
const userMsg = theme.bg('userMessageBg',
theme.fg('userMessageText', 'Hello')
)
```
**Color resolution:**
1. **Detect terminal capabilities:**
- Check `$COLORTERM` env var (`truecolor` or `24bit` → truecolor support)
- Check `$TERM` env var (`*-256color` → 256-color support)
- Fallback to 256-color mode if detection fails
2. **Load JSON theme file**
3. **Resolve `vars` references recursively:**
```json
{
"vars": {
"primary": "#0066cc",
"accent": "primary"
},
"colors": {
"accent": "accent" // → "primary" → "#0066cc"
}
}
```
4. **Convert colors to ANSI codes based on terminal capability:**
**Truecolor mode (24-bit):**
- Hex (`"#ff0000"`) → `\x1b[38;2;255;0;0m`
- 256-color (`42`) → `\x1b[38;5;42m` (keep as-is)
- Empty string (`""`) → `\x1b[39m`
**256-color mode:**
- Hex (`"#ff0000"`) → convert to nearest RGB cube color → `\x1b[38;5;196m`
- 256-color (`42`) → `\x1b[38;5;42m` (keep as-is)
- Empty string (`""`) → `\x1b[39m`
**Hex to 256-color conversion:**
```typescript
// Convert RGB to 6x6x6 cube (colors 16-231)
r_index = Math.round(r / 255 * 5)
g_index = Math.round(g / 255 * 5)
b_index = Math.round(b / 255 * 5)
color_index = 16 + 36 * r_index + 6 * g_index + b_index
```
5. **Cache as `Theme` instance**
This ensures themes work correctly regardless of terminal capabilities, with graceful degradation from truecolor to 256-color.

# Theme System Analysis
## Problem Statement
Issue #7: In terminals with light backgrounds, some outputs use dark colors that are hard to read. We need a theme system that allows users to choose between light and dark themes.
## Current Color Usage Analysis
### Color Usage Statistics
Total chalk color calls: 132 across 14 files
Most frequent colors:
- `chalk.dim` (48 occurrences) - Used for secondary text
- `chalk.gray` (28 occurrences) - Used for borders, metadata, dimmed content
- `chalk.bold` (20 occurrences) - Used for emphasis
- `chalk.blue` (12 occurrences) - Used for selections, borders, links
- `chalk.cyan` (9 occurrences) - Used for primary UI elements (logo, list bullets, code)
- `chalk.red` (7 occurrences) - Used for errors, stderr output
- `chalk.green` (6 occurrences) - Used for success, stdout output
- `chalk.yellow` (3 occurrences) - Used for headings in markdown
- `chalk.bgRgb` (6 occurrences) - Used for custom backgrounds in Text/Markdown
### Files Using Colors
#### coding-agent Package
1. **main.ts** - CLI output messages
2. **tui/assistant-message.ts** - Thinking text (gray italic), errors (red), aborted (red)
3. **tui/dynamic-border.ts** - Configurable border color (default blue)
4. **tui/footer.ts** - Stats and pwd (gray)
5. **tui/model-selector.ts** - Borders (blue), selection arrow (blue), provider badge (gray), checkmark (green)
6. **tui/session-selector.ts** - Border (blue), selection cursor (blue), metadata (dim)
7. **tui/thinking-selector.ts** - Border (blue)
8. **tui/tool-execution.ts** - stdout (green), stderr (red), dim lines (dim), line numbers
9. **tui/tui-renderer.ts** - Logo (bold cyan), instructions (dim/gray)
#### tui Package
1. **components/editor.ts** - Horizontal border (gray)
2. **components/loader.ts** - Spinner (cyan), message (dim)
3. **components/markdown.ts** - Complex color system:
- H1 headings: bold.underline.yellow
- H2 headings: bold.yellow
- H3+ headings: bold
- Code blocks: gray (delimiters), dim (indent), green (code)
- List bullets: cyan
- Blockquotes: gray (pipe), italic (text)
- Horizontal rules: gray
- Inline code: gray (backticks), cyan (code)
- Links: underline.blue (text), gray (URL)
- Strikethrough: strikethrough
- Tables: bold (headers)
4. **components/select-list.ts** - No matches (gray), selection arrow (blue), selected item (blue), description (gray)
5. **components/text.ts** - Custom bgRgb support
### Color System Architecture
#### Current Implementation
- Colors are hardcoded using `chalk` directly
- No centralized theme management
- No way to switch themes at runtime
- Some components accept color parameters (e.g., DynamicBorder, Text, Markdown)
#### Markdown Component Color System
The Markdown component has a `Color` type enum:
```typescript
type Color = "black" | "red" | "green" | "yellow" | "blue" | "magenta" | "cyan" | "white" | "gray" |
"bgBlack" | "bgRed" | "bgGreen" | "bgYellow" | "bgBlue" | "bgMagenta" | "bgCyan" | "bgWhite" | "bgGray"
```
It accepts optional `bgColor` and `fgColor` parameters, plus `customBgRgb`.
## Proposed Solution
### Theme Structure
Create a centralized theme system with semantic color names:
```typescript
interface Theme {
name: string;
// UI Chrome
border: ChalkFunction;
selection: ChalkFunction;
selectionText: ChalkFunction;
// Text hierarchy
primary: ChalkFunction;
secondary: ChalkFunction;
dim: ChalkFunction;
// Semantic colors
error: ChalkFunction;
success: ChalkFunction;
warning: ChalkFunction;
info: ChalkFunction;
// Code/output
code: ChalkFunction;
codeDelimiter: ChalkFunction;
stdout: ChalkFunction;
stderr: ChalkFunction;
// Markdown specific
heading1: ChalkFunction;
heading2: ChalkFunction;
heading3: ChalkFunction;
link: ChalkFunction;
linkUrl: ChalkFunction;
listBullet: ChalkFunction;
blockquote: ChalkFunction;
blockquotePipe: ChalkFunction;
inlineCode: ChalkFunction;
inlineCodeDelimiter: ChalkFunction;
// Backgrounds (optional, for components like Text/Markdown)
backgroundRgb?: { r: number; g: number; b: number };
}
type ChalkFunction = (str: string) => string;
```
### Built-in Themes
#### Dark Theme (current default)
```typescript
const darkTheme: Theme = {
name: "dark",
border: chalk.blue,
selection: chalk.blue,
selectionText: chalk.blue,
primary: (s) => s, // no color
secondary: chalk.gray,
dim: chalk.dim,
error: chalk.red,
success: chalk.green,
warning: chalk.yellow,
info: chalk.cyan,
code: chalk.green,
codeDelimiter: chalk.gray,
stdout: chalk.green,
stderr: chalk.red,
heading1: chalk.bold.underline.yellow,
heading2: chalk.bold.yellow,
heading3: chalk.bold,
link: chalk.underline.blue,
linkUrl: chalk.gray,
listBullet: chalk.cyan,
blockquote: chalk.italic,
blockquotePipe: chalk.gray,
inlineCode: chalk.cyan,
inlineCodeDelimiter: chalk.gray,
};
```
#### Light Theme
```typescript
const lightTheme: Theme = {
name: "light",
border: chalk.blue,
selection: chalk.blue,
selectionText: chalk.blue.bold,
primary: (s) => s,
secondary: chalk.gray,
dim: chalk.gray, // Don't use chalk.dim on light backgrounds
error: chalk.red.bold,
success: chalk.green.bold,
warning: chalk.yellow.bold,
info: chalk.cyan.bold,
code: chalk.green.bold,
codeDelimiter: chalk.gray,
stdout: chalk.green.bold,
stderr: chalk.red.bold,
heading1: chalk.bold.underline.blue,
heading2: chalk.bold.blue,
heading3: chalk.bold,
link: chalk.underline.blue,
linkUrl: chalk.blue,
listBullet: chalk.blue.bold,
blockquote: chalk.italic,
blockquotePipe: chalk.gray,
inlineCode: chalk.blue.bold,
inlineCodeDelimiter: chalk.gray,
};
```
### Implementation Plan
#### 1. Create Theme Module
**Location:** `packages/tui/src/theme.ts`
```typescript
export interface Theme { ... }
export const darkTheme: Theme = { ... };
export const lightTheme: Theme = { ... };
export const themes = { dark: darkTheme, light: lightTheme };
let currentTheme: Theme = darkTheme;
export function setTheme(theme: Theme): void {
currentTheme = theme;
}
export function getTheme(): Theme {
return currentTheme;
}
```
#### 2. Update Settings Manager
**Location:** `packages/coding-agent/src/settings-manager.ts`
Add `theme` field to Settings interface:
```typescript
export interface Settings {
lastChangelogVersion?: string;
theme?: "dark" | "light";
}
```
#### 3. Create Theme Selector Component
**Location:** `packages/coding-agent/src/tui/theme-selector.ts`
Similar to ModelSelector and ThinkingSelector, create a TUI component for selecting themes.
#### 4. Refactor Color Usage
Replace all hardcoded `chalk.*` calls with `theme.*`:
**Example - Before:**
```typescript
lines.push(chalk.blue("─".repeat(width)));
const cursor = chalk.blue("› ");
```
**Example - After:**
```typescript
const theme = getTheme();
lines.push(theme.border("─".repeat(width)));
const cursor = theme.selection("› ");
```
#### 5. Update Components
##### High Priority (User-facing content issues)
1. **markdown.ts** - Update all color calls to use theme
2. **tool-execution.ts** - stdout/stderr colors
3. **assistant-message.ts** - Error messages
4. **tui-renderer.ts** - Logo and instructions
5. **footer.ts** - Stats display
##### Medium Priority (UI chrome)
6. **dynamic-border.ts** - Accept theme parameter
7. **model-selector.ts** - Selection colors
8. **session-selector.ts** - Selection colors
9. **thinking-selector.ts** - Border colors
10. **select-list.ts** - Selection colors
11. **loader.ts** - Spinner color
12. **editor.ts** - Border color
##### Low Priority (CLI output)
13. **main.ts** - CLI messages
#### 6. Add Theme Slash Command
**Location:** `packages/coding-agent/src/tui/tui-renderer.ts`
Add `/theme` command similar to `/model` and `/thinking`.
#### 7. Initialize Theme on Startup
**Location:** `packages/coding-agent/src/main.ts`
```typescript
// Load theme from settings
const settingsManager = new SettingsManager();
const themeName = settingsManager.getTheme() || "dark";
const theme = themes[themeName] || darkTheme;
setTheme(theme);
```
### Migration Strategy
1. **Phase 1:** Create theme infrastructure (theme.ts, types, built-in themes)
2. **Phase 2:** Update TUI package components (markdown, text, loader, editor, select-list)
3. **Phase 3:** Update coding-agent TUI components (all tui/*.ts files)
4. **Phase 4:** Add theme selector and persistence
5. **Phase 5:** Update CLI output in main.ts (optional, low priority)
### Testing Plan
1. Test both themes in terminals with light backgrounds
2. Test both themes in terminals with dark backgrounds
3. Verify theme switching works at runtime via `/theme`
4. Verify theme persists across sessions via settings.json
5. Test all components for readability in both themes
### Open Questions
1. Should we support custom user themes loaded from a JSON file?
2. Should we auto-detect terminal background color and choose theme automatically?
3. Should theme apply to background colors used in Text/Markdown components?
4. Do we need more than two themes initially?
### Breaking Changes
None - the default theme will remain "dark" matching current behavior.
### Performance Considerations
- Theme getter is called frequently (on every render)
- Should be a simple variable access, not a function call chain
- Consider caching theme functions if performance becomes an issue
