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.
* feat(coding-agent): add event bus for tool/hook communication
Adds pi.events API enabling custom tools and hooks to communicate via
pub/sub. Tools can emit events, hooks can listen. Shared EventBus instance
created per session in createAgentSession().
- EventBus interface with emit() and on() methods
- on() returns unsubscribe function
- Threaded through hook and tool loaders
- Documented in hooks.md and custom-tools.md
* fix(coding-agent): wrap event handlers to catch errors
* docs: note async handler error handling for event bus
* feat(coding-agent): add sendMessage to tools, nextTurn delivery mode
- Custom tools now have pi.sendMessage() for direct agent notifications
- New deliverAs: 'nextTurn' queues messages for next user prompt
- Fix: hooks and tools now share the same eventBus (was isolated before)
* fix(coding-agent): nextTurn delivery should always queue, even when streaming
* Add skills system with Claude Code compatibility
* consolidate skills into single module, merge loaders, add <available_skills> XML tags
* add Codex CLI skills compatibility, skip hidden/symlinks
Browse previously submitted prompts using Up/Down arrow keys, similar to
shell history and Claude Code's prompt history feature.
- Up arrow when editor is empty: browse to older prompts
- Down arrow when browsing: return to newer prompts or clear editor
- Cursor movement within multi-line history entries supported
- History is session-scoped, stores up to 100 entries
- Consecutive duplicates are not added to history
Includes 15 new tests for history navigation behavior.
