feat: Implement Phase 1 of SDK agent architecture with hook integration
- Added CLI commands for context, new session, save observation, and summary. - Created HooksDatabase for managing SDK sessions and observations. - Implemented migration 004 to add new tables: sdk_sessions, observation_queue, observations, and session_summaries. - Developed hook functions for context display, session initialization, observation queuing, and session finalization. - Added comprehensive tests for database schema and hook functionality. - Documented Phase 1 implementation in PHASE1-COMPLETE.md.

# 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
|
||||
|
||||

||||
### Modified Files
|
||||

|
||||
- [src/services/sqlite/index.ts](src/services/sqlite/index.ts:13) - Exported HooksDatabase
|
||||

|
||||
|
||||
## 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.
