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
feat(coding-agent): support searching/resuming sessions by ID
- Session picker (pi -r) now searches session IDs in addition to message content
- --session flag accepts UUID prefix (e.g., pi --session a8ec1c2a)
- Documented in README.md

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
- 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.
