- Replace per-extension closures with shared ExtensionRuntime
- Split context actions: ExtensionContextActions (required) + ExtensionCommandContextActions (optional)
- Rename LoadedExtension to Extension, remove setter methods
- Change runner.initialize() from options object to positional params
- Derive hasUI from uiContext presence (no separate param)
- Add warning when extensions override built-in tools
- RPC and print modes now provide full command context actions
BREAKING CHANGE: Extension system types and initialization API changed.
See CHANGELOG.md for migration details.
When enabledModels is configured without thinking level suffixes (e.g.,
'claude-opus-4-5' instead of 'claude-opus-4-5:high'), the scoped model's
default 'off' thinking level was overriding defaultThinkingLevel from
settings.
Now thinkingLevel in ScopedModel is optional (undefined means 'not
explicitly specified'). When passing to SDK, undefined values are filled
with defaultThinkingLevel from settings.
Adds StdinBuffer class (adapted from OpenTUI, MIT license) to split
batched stdin into individual sequences before they reach components.
This fixes key presses being dropped when batched with release events,
which commonly occurs over SSH due to network buffering.
- Each handleInput() call now receives a single event
- matchesKey() and isKeyRelease() work correctly without batching awareness
- Properly buffers incomplete escape sequences across chunks
- Handles bracketed paste mode
Addresses #538
When a user edits settings.json while pi is running (e.g., adding
enabledModels), those settings would be lost when pi saved other
changes (e.g., changing thinking level via Shift+Tab).
The fix re-reads the file before saving and merges the current file
contents with in-memory changes, so external edits are preserved.
Adds test coverage for SettingsManager.
Extension UI dialogs (select, confirm, input) now support a timeout option
that auto-dismisses with a live countdown display. Simpler alternative to
manually managing AbortSignal for timed dialogs.
Also adds ExtensionUIDialogOptions type export and updates RPC mode to
forward timeout to clients.
- Enable flag 2 in Kitty protocol for event type reporting
- Add isKeyRelease() and isKeyRepeat() functions
- Parse event type suffix (:1/:2/:3) in Kitty sequences
- Export KeyEventType type
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#495

Google streaming may emit thoughtSignature without thought=true (including empty-text signature-only parts). Treat non-empty thoughtSignature as thinking to avoid leaking reasoning into normal text and retain signature across streaming deltas. Add unit test coverage.
