# Phase 8.6: Help Tool Extensions
**Estimated Time:** 2 days
**Dependencies:** Phase 8.5
**Status:** ⏭️ Skipped
## Overview
Extend the help tool with action parameter (guidance, stuck, escalate, checkpoint) and signal handlers for intervention.
**Note:** This phase has been skipped as it's not required for the current implementation. The help tool works as-is for basic guidance. Signal handlers and intervention features can be added later if needed.
## What This Phase Accomplishes
- Add `action` parameter to help tool
- Guidance topics (kiwi-overview, permissions, mcps, stuck)
- Signal handlers (route stuck/escalate to appropriate handlers)
- Integration with loop detector
## Files to Modify/Create
- `kiwi_mcp/tools/help.py` (extend)
- `kiwi_mcp/runtime/intervention.py` (new)
- `tests/tools/test_help_signals.py` (new)
## Task Breakdown
1. Extend help tool with action parameter
2. Implement guidance topics
3. Implement signal handlers
4. Integrate with loop detector
5. Write tests
## Success Criteria
- [ ] Help tool accepts action parameter
- [ ] All actions work (guidance, stuck, escalate, checkpoint)
- [ ] Signal handlers route correctly
- [ ] Loop detector integration works
- [ ] Tests cover all actions
