Transfers context to a new focused session instead of compacting.
User provides a goal, hook generates a prompt with relevant context,
creates a new session with parent tracking, and loads the prompt
as a draft in the editor for review.
Inspired by Amp's handoff feature.
CustomToolContext now has:
- isIdle() - check if agent is streaming
- hasQueuedMessages() - check if user has queued messages
- abort() - abort current operation (fire-and-forget)
Changed abort() signature from Promise<void> to void in both
HookContext and CustomToolContext. The abort is fire-and-forget:
it calls session.abort() without awaiting, so the abort signal
is set immediately while waitForIdle() runs in the background.
Fixes#388
HookContext (all events):
- isIdle() - read-only state check
- hasQueuedMessages() - read-only state check
- abort() - fire-and-forget, does not wait
HookCommandContext (slash commands only):
- waitForIdle() - waits for agent to finish
- newSession(options?) - create new session
- branch(entryId) - branch from entry
- navigateTree(targetId, options?) - navigate session tree
Session control methods moved from HookAPI (pi.*) to HookCommandContext (ctx.*)
because they can deadlock when called from event handlers that run inside
the agent loop (tool_call, tool_result, context events).
HookAPI additions:
- pi.newSession(options?) - create new session with optional setup callback
- pi.branch(entryId) - branch from a specific entry
- pi.navigateTree(targetId, options?) - navigate the session tree
HookContext additions:
- ctx.isIdle() - check if agent is streaming
- ctx.waitForIdle() - wait for agent to finish
- ctx.abort() - abort current operation
- ctx.hasQueuedMessages() - check for queued user messages
These enable hooks to programmatically manage sessions (handoff, templates)
and check agent state before showing interactive UI.
Fixes#388
- Remove session_before_new and session_new hook events
- Add reason: 'new' | 'resume' to session_before_switch and session_switch events
- Remove 'new' reason from custom tool onSession (use 'switch' for both /new and /resume)
- Rename reset() to newSession(options?) in AgentSession
- Add NewSessionOptions with optional parentSession for lineage tracking
- Rename branchedFrom to parentSession in SessionHeader
- Rename RPC reset command to new_session with optional parentSession
- Update example hooks to use new event structure
- Update documentation and changelog
Based on discussion in #293
Strip all Unicode format characters (category Cf) before passing to
string-width. These are invisible control characters that crash
string-width but have no visible width anyway.
Closes#390
- Add optional 'export' section to theme JSON with pageBg, cardBg, infoBg
- If not specified, colors are auto-derived from userMessageBg
- Add export colors to dark.json and light.json
- Update theme-schema.json and TypeBox schema
- Add documentation to docs/theme.md
- Add margin-top back to tool-output for spacing between header and content
- Add theme property to HookUIContext interface
- Implement in interactive, RPC, and no-op contexts
- Add status-line.ts example hook
- Document styling with theme colors in hooks.md
The white-space: pre-wrap on .tool-output was preserving template
literal whitespace (newlines and indentation). The pre elements
inside still have pre-wrap for actual code content.
* Add ctx.ui.setStatus(key, text) API for hooks to display status in footer
- Add setStatus to HookUIContext interface
- Implement in interactive mode (FooterComponent)
- Implement in RPC mode (fire-and-forget)
- Add no-op implementations for headless contexts
- Multiple statuses displayed on single line, sorted by key
- Supports ANSI styling (hooks handle their own colors)
* Remove setStatus from changelog for now
* Fix hook status API to follow TUI rules
- Sanitize status text: replace newlines, tabs, carriage returns with spaces
- Truncate combined status line to terminal width using truncateToWidth
- Update JSDoc to document sanitization and truncation behavior
- Remove unused createHookUIContext method
- Add missing setStatus to test mock
* Add setStatus to changelog
* Use dim ellipsis for hook status truncation for consistency with footer style

Added glob pattern support (e.g., github-copilot/*, *sonnet*) to --models
and enabledModels. Patterns are matched against both provider/modelId and
just modelId, so *sonnet* works without requiring anthropic/*sonnet*.
The existing fuzzy substring matching for non-glob patterns is preserved.

When creating a new session, initial model and thinking level were set
on the agent but never saved to session file. This caused --resume to
default thinking level to 'off'.
