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#350
- CustomAgentTool renamed to CustomTool
- ToolAPI renamed to CustomToolAPI
- ToolContext renamed to CustomToolContext
- ToolSessionEvent renamed to CustomToolSessionEvent
- Added CustomToolContext parameter to execute() and onSession()
- CustomToolFactory now returns CustomTool<any, any> for type compatibility
- dispose() replaced with onSession({ reason: 'shutdown' })
- Added wrapCustomTool() to convert CustomTool to AgentTool
- Session exposes setToolUIContext() instead of leaking internals
- Fix ToolExecutionComponent to sync with toolOutputExpanded state
- Update all custom tool examples for new API
Breaking change: CustomAgentTool.dispose() removed. Use onSession with
reason 'shutdown' instead for cleanup.
- Add 'shutdown' to SessionEvent.reason for custom tools
- Remove dispose() method from CustomAgentTool interface
- Make emitToolSessionEvent() public on AgentSession
- Emit shutdown event to tools in InteractiveMode.shutdown()
- Update custom-tools.md with new API and examples
- Add selectedBg theme color for active line highlight
- Fix filter modes:
- no-tools: default minus tool results (still hides label/custom)
- user-only: just user messages
- labeled-only: just labeled entries
- all: everything
- Update theme.md with new color tokens (50 total)
Both auto_compaction_end and executeCompaction were manually adding
CompactionSummaryMessageComponent instead of using addMessageToChat,
which caused missing spacers. Now both use addMessageToChat for
consistent spacing and expansion state handling.
- Move compaction.ts to src/core/compaction/compaction.ts
- Extract branch summarization to src/core/compaction/branch-summarization.ts
- Add index.ts to re-export all compaction utilities
- Update all imports across the codebase
- Check response.stopReason instead of catching errors for abort detection
- Return result object from _generateBranchSummary instead of throwing
- Fix summary attachment: attach to navigation target position, not old branch
- Support root-level summaries (parentId=null) in branchWithSummary
- Remove setTimeout hack for re-showing tree selector on abort
- Show ├─ for non-last siblings, └─ for last sibling
- Show │ gutter for descendants of non-last siblings
- Properly handle multiple roots display shift
- At indent 0: stay flat unless parent branches
- At indent 1: children go to indent 2 (visual grouping)
- At indent 2+: stay flat for single-child chains
- Remove gutter/connector complexity for now
- Only indent when parent has siblings (branch point)
- gutterLevels array tracks which levels need │ vs spaces
- connector: none/branch/last for ├─/└─ display
- Tool results show formatted call info like [read: path:1-10], [bash: cmd]
- Skip assistant messages with stopReason error/aborted
- Skip assistant messages with only tool calls (no text)
- Format built-in tools like tool-execution.ts (read, write, edit, bash, grep, find, ls)
- Custom tools show truncated JSON args
- Label editing with 'l' key
- Ctrl+O cycles through filters: default -> user-only -> labeled-only -> all
- Preserve cursor position when toggling filters
- Labels shown at front of node
- Normalize tabs/newlines in content
- extractContent limited to 200 chars for performance
- truncateToWidth on all rendered lines
- Iterative flattenTree to avoid stack overflow
- Linear chain optimization (no indent for single-child chains)
- Add TreeSelectorComponent with ASCII tree visualization
- Add AgentSession.navigateTree() for switching branches
- Add session_before_tree/session_tree hook events
- Add SessionManager.resetLeaf() for navigating to root
- Change leafId from string to string|null for consistency with parentId
- Support optional branch summarization when switching
- Update buildSessionContext() to handle null leafId
- Add /tree to slash commands in interactive mode
Major changes:
- Replace monolithic SessionEvent with reason discriminator with individual
event types: session_start, session_before_switch, session_switch,
session_before_new, session_new, session_before_branch, session_branch,
session_before_compact, session_compact, session_shutdown
- Each event has dedicated result type (SessionBeforeSwitchResult, etc.)
- HookHandler type now allows bare return statements (void in return type)
- HookAPI.on() has proper overloads for each event with correct typing
Additional fixes:
- AgentSession now always subscribes to agent in constructor (was only
subscribing when external subscribe() called, breaking internal handlers)
- Standardize on undefined over null throughout codebase
- HookUIContext methods return undefined instead of null
- SessionManager methods return undefined instead of null
- Simplify hook exports to 'export type * from types.js'
- Add detailed JSDoc for skipConversationRestore vs cancel
- Fix createBranchedSession to rebuild index in persist mode
- newSession() now returns the session file path
Updated all example hooks, tests, and emission sites to use new event types.
When custom renderer returns a component with its own background,
don't wrap it in another background box. The nested bg resets
were causing padding to lose its background color.
