* fix: background task completion detection and silent notifications
- Fix TS2742 by adding explicit ToolDefinition type annotations
- Add stability detection (3 consecutive stable polls after 10s minimum)
- Remove early continue when sessionStatus is undefined
- Add silent notification system via tool.execute.after hook injection
- Change task retention from 200ms to 5 minutes for background_output retrieval
- Fix formatTaskResult to sort messages by time descending
Fixes hanging background tasks that never complete due to missing sessionStatus.
* fix: improve background task completion detection and message extraction
- Add stability-based completion detection (10s min + 3 stable polls)
- Fix message extraction to recognize 'reasoning' parts from thinking models
- Switch from promptAsync() to prompt() for proper agent initialization
- Remove model parameter from prompt body (use agent's configured model)
- Add fire-and-forget prompt pattern for sisyphus_task sync mode
- Add silent notification via tool.execute.after hook injection
- Fix indentation issues in manager.ts and index.ts
Incorporates fixes from:
- PR #592: Stability detection mechanism
- PR #610: Model parameter passing (partially)
- PR #628: Completion detection improvements
Known limitation: Thinking models (e.g. claude-*-thinking-*) cause
JSON Parse errors in child sessions. Use non-thinking models for
background agents until OpenCode core resolves this.
* fix: add tool_result handling and pendingByParent tracking for resume/external tasks
Addresses code review feedback from PR #638:
P1: Add tool_result type to validateSessionHasOutput() to prevent
false negatives for tool-only background tasks that would otherwise
timeout after 30 minutes despite having valid results.
P2: Add pendingByParent tracking to resume() and registerExternalTask()
to prevent premature 'ALL COMPLETE' notifications when mixing
launched and resumed tasks.
* fix: address code review feedback - log messages, model passthrough, sorting, race condition
- Fix misleading log messages: 'promptAsync' -> 'prompt (fire-and-forget)'
- Restore model passthrough in launch() for Sisyphus category configs
- Fix call-omo-agent sorting: use time.created number instead of String(time)
- Fix race condition: check promptError inside polling loop, not just after 100ms
- Remove unused chat message notification handler
- Remove formatDuration and formatNotifications helpers
- Simplify to event-only handling
- Remove chat.message hook call from main plugin
Background task notifications now rely on event-based system only.
