# Phase 1 Implementation - Complete ✅
|
|
|
|
Phase 1 of the REFACTOR-PLAN.md has been successfully implemented and tested.
|
|
|
|
## What Was Implemented
|
|
|
|
### 1. Database Schema (Migration 004)
|
|
Created four new tables to support the SDK agent architecture:
|
|
|
|
- **`sdk_sessions`** - Tracks SDK streaming sessions
|
|
- **`observation_queue`** - Message queue for pending observations
|
|
- **`observations`** - Stores extracted observations from SDK
|
|
- **`session_summaries`** - Stores structured session summaries
|
|
|
|
All tables include proper indexes for performance and foreign key constraints for data integrity.
|
|
|
|
### 2. Shared Database Layer
|
|
Created `HooksDatabase` class ([src/services/sqlite/HooksDatabase.ts](src/services/sqlite/HooksDatabase.ts)) that provides:
|
|
|
|
- Simple, synchronous database operations for hooks
|
|
- No complex logic - just basic CRUD operations
|
|
- Optimized SQLite settings (WAL mode, foreign keys enabled)
|
|
- Methods for all hook operations:
|
|
- `getRecentSummaries()` - Retrieve session context
|
|
- `createSDKSession()` - Initialize new session
|
|
- `queueObservation()` - Add observation to queue
|
|
- `storeObservation()` - Save SDK observations
|
|
- `storeSummary()` - Save session summaries
|
|
- And more...
|
|
|
|
### 3. Hook Functions
|
|
Implemented all four hook functions in [src/hooks/](src/hooks/):
|
|
|
|
#### **context.ts** - SessionStart Hook
|
|
- Shows user recent session context on startup
|
|
- Formats summaries in markdown for Claude
|
|
- Exits silently if no context or errors occur
|
|
|
|
#### **save.ts** - PostToolUse Hook
|
|
- Queues tool observations for SDK processing
|
|
- Skips low-value tools (TodoWrite, ListMcpResourcesTool)
|
|
- Non-blocking - returns immediately
|
|
|
|
#### **new.ts** - UserPromptSubmit Hook
|
|
- Initializes SDK session in database
|
|
- Prepares for SDK worker spawn (TODO in Phase 2)
|
|
- Non-blocking - returns immediately
|
|
|
|
#### **summary.ts** - Stop Hook
|
|
- Queues FINALIZE message for SDK
|
|
- Signals SDK to generate session summary
|
|
- Non-blocking - returns immediately
|
|
|
|
### 4. CLI Integration
|
|
Added four new commands to [src/bin/cli.ts](src/bin/cli.ts:227-274):
|
|
|
|
```bash
|
|
claude-mem context # SessionStart hook
|
|
claude-mem new # UserPromptSubmit hook
|
|
claude-mem save # PostToolUse hook
|
|
claude-mem summary # Stop hook
|
|
```
|
|
|
|
All commands read JSON input from stdin and execute the corresponding hook function.
|
|
|
|
### 5. Testing
|
|
Created comprehensive test suite ([test-phase1.ts](test-phase1.ts)) that validates:
|
|
|
|
- ✅ Database schema migration 004 applied correctly
|
|
- ✅ All four tables exist
|
|
- ✅ SDK session creation and retrieval
|
|
- ✅ Observation queue operations
|
|
- ✅ Observation and summary storage
|
|
- ✅ Session status transitions
|
|
|
|
**All tests pass! 🎉**
|
|
|
|
## What's Left for Phase 2
|
|
|
|
The foundation is complete. Next steps:
|
|
|
|
1. **SDK Worker Process** - Implement the background agent that:
|
|
- Polls observation queue
|
|
- Sends observations to Claude SDK
|
|
- Parses XML responses (`<observation>` and `<summary>` blocks)
|
|
- Stores results in database
|
|
|
|
2. **SDK Prompts** - Implement the three prompt builders:
|
|
- `buildInitPrompt()` - Initialize SDK agent
|
|
- `buildObservationPrompt()` - Send tool observation
|
|
- `buildFinalizePrompt()` - Request session summary
|
|
|
|
3. **Process Management** - Update [src/hooks/new.ts](src/hooks/new.ts:35-42) to spawn SDK worker as detached process
|
|
|
|
4. **End-to-End Testing** - Test with real Claude Code session
|
|
|

|
|

|
## Verification
|
|
|
|
To verify Phase 1 implementation:
|
|
|
|
```bash
|
|
# Build
|
|
bun run build
|
|
|
|
# Run tests
|
|
bun test-phase1.ts
|
|
|
|
# Check hook commands exist
|
|
./dist/claude-mem.min.js --help | grep -A 1 'context\|new\|save\|summary'
|
|
```
|
|
|
|
All should pass without errors.
|
|
|
|
## Next Steps
|
|
|
|
Ready to proceed to Phase 2: **SDK Worker Implementation**
|
|
|
|
The architecture is sound, the database layer is working, and all hook functions are ready to integrate with the SDK worker process.
