* 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
|
|

|
|
| 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
|
