## Current Focus

### Phase 0: Current System Analysis
**Status:** COMPLETE ✅
**Completed:** 2026-01-14
**Duration:** ~4 hours (5 parallel agents)

**ALL SUCCESS CRITERIA MET:**
- [x] 5 analysis documents created in `docs/analysis/`
- [x] Hook.plugin_name confirmed (not plugin object) - CRITICAL FINDING
- [x] All 5 tool call sites identified and documented
- [x] Question Gate flow fully mapped
- [x] Integration points identified for Phase 6

**Analysis Documents:**
1. docs/analysis/current-message-schema.md (Agent a511ec4)
2. docs/analysis/hook-system-audit.md (Agent ae7bc88) - CRITICAL: plugin_name verified
3. docs/analysis/error-handling-patterns.md (Agent a301ee0)
4. docs/analysis/tool-system.md (Agent a565ad2) - Question Gate fully mapped
5. docs/analysis/message-building.md (Agent a1491aa)
6. docs/analysis/PHASE0-COMPLETE.md (Summary)

**Key Findings:**
- Hook dataclass uses plugin_name (string) not plugin (object) - NO breaking changes needed
- Question Gate protocol fully documented with exact line numbers
- All 5 tool call sites identified in llm_service.py and tool_executor.py
- Current adapter pattern is solid foundation for multi-provider support
- No custom exception hierarchy exists (needs creation in Phase 1)

### Phase 1: Foundation & Type System
**Status:** READY TO START
**Planned:** 2026-01-15 (next phase)
**Duration:** 4-5 days (sequential, not parallel)

---

## Coverage Status

**Target:** 65% overall
**Current:** TBD (Phase 0 complete, Phase 1 not started)

**Phase Coverage (To be tracked):**
- Phase 0: N/A (analysis phase)
- Phase 1: TBD (target 75-80%)
- Phase 2: TBD (target 75-80%)
- Phase 3: TBD (target 75%)
- Phase 4: TBD (target 70%)
- Phase 5: TBD (target integration testing)
- Phase 6: TBD (target 70%)
- Phase 7: TBD (target 70%)
- Phase 8: TBD (target 80%)
- Phase 9: TBD (target 55%)
- Phase 10: TBD (target 65%+ final)

## Risks & Issues

### Active Blockers
**NONE** ✅ - Phase 0 complete with no blockers

### Risks Identified

**HIGH RISK:**
1. **Phase 6: LLMService Integration** (Days 32-39)
   - 15+ call sites to update
   - 3 sub-phases required (wrapper → explicit → testing)
   - Question Gate must not break
   - Streaming changes affect multiple paths

2. **Phase 5: Integration Updates** (Days 26-31)
   - Touches core files
   - MCP integration must work with both providers
   - All existing tests must pass

**MITIGATION:**
- Phase 6 will use 3-phase approach with feature flag for rollback
- Commit frequently for easy rollback
- Extensive testing after each sub-phase
- Question Gate testing explicitly prioritized

### Mitigation Strategies (From Addendum)
- [x] Priority 0: Hook adapter using plugin_name field - VERIFIED COMPATIBLE ✅
- [ ] Priority 0: 4-tier keyring fallback - Implement in Phase 1
- [ ] Priority 1: Resource lifecycle testing - Implement in Phase 10
- [ ] Priority 2: Tool accumulator migration (3-phase) - Implement in Phase 6

## Key Decisions

### Decisions Made

**2026-01-14: Phase 0 Analysis Complete**
- Hook system verified: uses plugin_name (string), NOT plugin (object)
- No breaking changes needed for hook adapter (Addendum Priority 0 RESOLVED)
- Question Gate flow fully mapped with exact line numbers
- All 5 tool call sites identified for Phase 6 integration
- Current adapter pattern solid foundation for multi-provider support
- Phase 1 will create custom exception hierarchy (none exists currently)

### Pending Decisions
NONE - All Phase 0 questions answered ✅

---

## Next Milestones

- [x] Phase 0 complete: 2026-01-14 ✅ (AHEAD of schedule!)
- [ ] Phase 1 complete: 2026-01-20 (target, 4-5 days)
- [ ] Phase 6 complete: 2026-02-20 (target - highest risk)
- [ ] Final completion: 2026-03-13 (target, 8-9 weeks)

**Timeline Status:** AHEAD OF SCHEDULE ✅
Phase 0 completed in ~4 hours vs. 3-4 days estimated.

## Quality Gates

### Phase 0 Exit Criteria
- All 5 analysis documents complete
- Integration points identified
- Hook system structure verified
- Tool calling flow documented
- Question Gate mechanism understood

### Project Completion Criteria
- All 10 phases complete
- 65%+ test coverage achieved
- All 9 existing plugins work
- Security audit passed
- Performance verified (no regressions)
- Documentation complete

---

## Notes

### Critical Addendum Items
1. **Priority 0:** 4-tier keyring fallback (OS keyring → encrypted file → env vars → plaintext)
2. **Priority 0:** Hook adapter uses plugin_name (not plugin object) to prevent crashes
3. **Priority 1:** Resource lifecycle testing methodology
4. **Priority 2:** Tool accumulator migration with 3-phase approach (wrapper → explicit → testing)

### Known Complexities
- Phase 4: OpenAI SDK integration nuances (6-7 days)
- Phase 5: Integration updates touch core files (HIGH RISK)
- Phase 6: LLMService integration with 15+ call sites (HIGH RISK, 3 sub-phases)
- Phase 8: Must maintain compatibility with all 9 existing plugins

**Next Update:** Phase 1 kickoff (Foundation & Type System)
**Status:** Phase 0 COMPLETE ✅
**Next Agent:** Phase1FoundationModels (Day 1-2 of Phase 1)
