feat(plugin): enhance context management and skill invocation (#239)
* fix(shellcheck): declare and assign separately in router.sh (SC2155)

* feat(plugin): enhance context management and skill invocation

- Update .context-manifest.json to include profile and detailed source information.
- Revise context-scout.md to clarify context root discovery and navigation.
- Modify commands to replace deprecated skills with updated ones (brainstorming → approach, systematic-debugging → debugger).
- Streamline install-context.md for clarity and remove interactive profile selection.
- Improve oac-status.md to provide a more comprehensive status report.
- Add OAC system paths to session-start.sh for better context management.
- Remove obsolete skills and improve documentation for existing commands.

# Lookup: Compatibility Layer Key Learnings
**Purpose**: Important insights from Phase 1-3 development
**Last Updated**: 2026-02-05
---
## TypeScript & Architecture
**TypeScript strict mode works perfectly**
- Zero compilation errors across all 14 source files
- Type safety catches conversion errors early
- Zod + TypeScript prevent runtime issues
**Adapter pattern scales beautifully**
- 3 adapters, 0 duplication, consistent API
- Template method pattern enables reuse
- BaseAdapter provides robust foundation
**Project structure is clean**
- Modular organization enables parallel development
- Function-based folders improve discoverability
- Barrel exports provide clean public API
---
## Code Quality
**Zod schemas are comprehensive**
- All 20+ schemas validated and working
- Runtime validation prevents bad data
- Type inference from schemas reduces duplication
**Pure functions enable testing**
- All mappers are pure functions (ToolMapper, PermissionMapper, etc.)
- Easy to test in isolation
- Deterministic conversion
- 97-100% coverage achieved on mappers
**Registry pattern is powerful**
- Map-based storage + aliases = great DX
- O(1) adapter lookup
- Type-safe registration
---
## Development Process
**Context loading matters**
- Reading standards BEFORE coding prevents rework
- ContextScout saves discovery time
- Persistent session context enables handoffs
**Approval gates prevent mistakes**
- User confirmation before destructive ops
- Incremental execution catches issues early
- Stop on failure prevents cascading errors
**Phase completion tracking**
- Phase 1: ✅ 100% (Foundation)
- Phase 2: ✅ 100% (Adapters + Tests)
- Phase 3: ✅ 100% (Mappers + Tests)
- Overall: 59.4% complete (19/32 subtasks)
---
## Feature Implementation
**Bidirectional conversion is achievable**
- All 3 adapters support roundtrip (OAC ↔ Tool ↔ OAC)
- Lossy conversions handled with clear warnings
- Feature parity matrix guides expectations
**Graceful degradation works**
- Clear warnings guide users on feature loss
- Binary permissions instead of failing
- Temperature ↔ Creativity mapping (approximate but functional)
**Translation Engine orchestration**
- Coordinates all mappers for complete translation
- Collects warnings from all components
- Provides preview/compatibility analysis
---
## Technical Wins
**Type-safe mappers prevent bugs**
- Model ID mapping with fallbacks
- Permission degradation with warnings
- Priority normalization handles edge cases
**Error handling is robust**
- Custom error classes per module
- Descriptive error messages
- Validation at boundaries
**Build system is solid**
- TypeScript compilation fast (~1s)
- All 485 tests pass
- Coverage exceeds 80% on tested modules
---
## Test Coverage Summary
| Category | Tests | Coverage |
|----------|-------|----------|
| Adapters | 236 | 97-99% |
| Mappers | 159 | 97-100% |
| Core | 90 | 98-99% |
| **Total** | **485** | **>80%** |
---
## What Worked Well
✅ Loading context before implementation
✅ Approval gates for safety
✅ Incremental execution (one step at a time)
✅ Template method pattern for adapters
✅ Pure functions for all mappers
✅ Zod validation throughout
✅ Comprehensive test coverage
✅ Conventional commits tracking
---
## What to Improve
⚠️ Could add integration tests earlier
⚠️ Feature parity matrix could be auto-generated
⚠️ CLI tool would help during development
⚠️ AgentLoader/AdapterRegistry need direct unit tests
---
## Remaining Work
**Phase 4 (CLI)**: 6 subtasks
- CLI scaffolding with Commander.js
- convert, validate, migrate, info commands
- Integration tests
**Phase 5 (Documentation)**: 7 subtasks
- 5 migration guides
- Feature matrices
- API documentation
