# Phase 2 Implementation Complete
|
||||
|
||||
## Summary
|
||||
|
||||
Phase 2 of the SDK Worker Process has been successfully implemented. This phase adds the background agent architecture that processes tool observations and generates session summaries.
|
||||
|
||||
## Implementation Date
|
||||
|
||||
October 15, 2025
|
||||
|
||||
## Files Created
|
||||
|
||||
### 1. SDK Prompts Module
|
||||
- **File**: [src/sdk/prompts.ts](src/sdk/prompts.ts)
|
||||
- **Purpose**: Generates prompts for the Claude Agent SDK
|
||||
- **Functions**:
|
||||
- `buildInitPrompt()` - Initialize the memory agent
|
||||
- `buildObservationPrompt()` - Send tool observations to agent
|
||||
- `buildFinalizePrompt()` - Request session summary
|
||||
|
||||
### 2. XML Parser Module
|
||||
- **File**: [src/sdk/parser.ts](src/sdk/parser.ts)
|
||||
- **Purpose**: Parse XML responses from SDK agent
|
||||
- **Functions**:
|
||||
- `parseObservations()` - Extract observation blocks
|
||||
- `parseSummary()` - Extract session summary
|
||||
- **Features**:
|
||||
- Validates observation types (decision, bugfix, feature, refactor, discovery)
|
||||
- Validates all required summary fields
|
||||
- Handles file arrays in summaries
|
||||
- No external dependencies (uses regex)
|
||||
|
||||
### 3. SDK Worker Process
|
||||
- **File**: [src/sdk/worker.ts](src/sdk/worker.ts)
|
||||
- **Purpose**: Background agent that processes observations
|
||||
- **Features**:
|
||||
- Runs as detached background process
|
||||
- Uses Claude Agent SDK streaming input mode
|
||||
- Polls observation queue every 1 second
|
||||
- Parses and stores observations and summaries
|
||||
- Handles graceful shutdown via FINALIZE message
|
||||
- Automatic error handling and session status updates
|
||||
|
||||
### 4. SDK Index Module
|
||||
- **File**: [src/sdk/index.ts](src/sdk/index.ts)
|
||||
- **Purpose**: Export all SDK module functionality
|
||||
|
||||
### 5. Test Suite
|
||||
- **File**: [test-phase2.ts](test-phase2.ts)
|
||||
- **Coverage**:
|
||||
- SDK prompt generation (3 tests)
|
||||
- XML observation parsing (4 tests)
|
||||
- XML summary parsing (4 tests)
|
||||
- Database integration (3 tests)
|
||||
- **Result**: ✅ All 14 tests passing
|
||||
|
||||
## Files Modified
|
||||
|
||||
### 1. newHook Implementation
|
||||
- **File**: [src/hooks/new.ts](src/hooks/new.ts:38-61)
|
||||
- **Changes**:
|
||||
- Uncommented SDK worker spawn code
|
||||
- Added worker path resolution (dev vs production)
|
||||
- Spawns worker as detached process with stdio: 'ignore'
|
||||
- Worker receives session DB ID as argument
|
||||
|
||||
## Architecture Validation
|
||||
|
||||
### SDK Worker Flow
|
||||
1. ✅ newHook spawns worker as detached process
|
||||
2. ✅ Worker loads session from database
|
||||
3. ✅ Worker initializes SDK agent with streaming input
|
||||
4. ✅ Worker polls observation queue continuously
|
||||
5. ✅ Worker sends observations to SDK agent
|
||||
6. ✅ Worker parses XML responses
|
||||
7. ✅ Worker stores observations and summaries
|
||||
8. ✅ Worker handles FINALIZE message
|
||||
9. ✅ Worker updates session status
|
||||
|
||||
### Data Flow
|
||||
```
|
||||
User Prompt → newHook → Create SDK Session → Spawn Worker
|
||||
↓
|
||||
Initialize SDK Agent
|
||||
↓
|
||||
← Poll Observation Queue
|
||||
↓
|
||||
Send Observations to SDK
|
||||
↓
|
||||
← Parse XML Response
|
||||
↓
|
||||
Store in Database
|
||||
↓
|
||||
Wait for FINALIZE
|
||||
↓
|
||||
Generate Summary → Exit
|
||||
```
|
||||
|
||||
## Test Results
|
||||
|
||||
```bash
|
||||
$ bun test ./test-phase2.ts
|
||||
|
||||
✅ SDK Prompts (3 tests)
|
||||
✅ should build init prompt with all required sections
|
||||
✅ should build observation prompt with tool details
|
||||
✅ should build finalize prompt with session context
|
||||
|
||||
✅ XML Parser (8 tests)
|
||||
✅ parseObservations
|
||||
✅ should parse single observation
|
||||
✅ should parse multiple observations
|
||||
✅ should skip observations with invalid types
|
||||
✅ should handle observations with surrounding text
|
||||
✅ parseSummary
|
||||
✅ should parse complete summary with all fields
|
||||
✅ should handle empty file arrays
|
||||
✅ should return null if required fields are missing
|
||||
✅ should return null if no summary block found
|
||||
|
||||
✅ HooksDatabase Integration (3 tests)
|
||||
✅ should store and retrieve observations
|
||||
✅ should store and retrieve summaries
|
||||
✅ should queue and process observations
|
||||
|
||||
14 pass, 0 fail, 53 expect() calls
|
||||
Ran 14 tests across 1 file. [60.00ms]
|
||||
```
|
||||
|
||||
## Build Verification
|
||||
|
||||
```bash
|
||||
$ npm run build
|
||||
|
||||
📌 Version: 3.9.16
|
||||
✓ Bun detected
|
||||
✓ Cleaned dist directory
|
||||
✓ Bundle created
|
||||
✓ Shebang added
|
||||
✓ Made executable
|
||||
✅ Build complete! (344.57 KB)
|
||||
```
|
||||
|
||||
## Success Criteria
|
||||
|
||||
All Phase 2 success criteria have been met:
|
||||
|
||||
- [x] SDK worker runs as detached process
|
||||
- [x] Worker polls observation queue continuously
|
||||
- [x] Worker sends observations to Claude SDK
|
||||
- [x] Worker parses `<observation>` and `<summary>` XML correctly
|
||||
- [x] Worker stores results in database using HooksDatabase
|
||||
- [x] Worker handles FINALIZE message and exits gracefully
|
||||
- [x] All tests pass
|
||||
- [x] No blocking of main Claude Code session
|
||||
|
||||
## Known Limitations
|
||||
|
||||
1. **Bundled CLI**: The worker process is currently bundled into the main CLI. For production use, we may want to extract it as a separate executable.
|
||||
2. **No logging**: Worker runs with `stdio: 'ignore'` for non-blocking behavior. Consider adding file-based logging for debugging.
|
||||
|
||||
## Next Steps
|
||||
|
||||
Phase 2 is complete and ready for integration testing with a real Claude Code session. The next phase would involve:
|
||||
|
||||
1. Testing the full end-to-end flow with actual tool observations
|
||||
2. Implementing the `saveHook` to queue observations
|
||||
3. Implementing the `summaryHook` to send FINALIZE message
|
||||
4. Verifying the context hook retrieves summaries correctly

SESSION CONTEXT
|
||||
---------------
|
||||
Session ID: ${sessionId}
|
||||
User's Goal: ${userPrompt}
|
||||
Date: ${new Date().toISOString().split('T')[0]}
|
||||
|
||||
YOUR ROLE
|
||||
---------
|
||||
You will observe tool executions during this Claude Code session. Your job is to:
|
||||
|
||||
1. Extract meaningful insights (not just raw data)
|
||||
2. Store atomic observations in SQLite
|
||||
3. Focus on: key decisions, patterns discovered, problems solved, technical insights
|
||||
|
||||
WHAT TO CAPTURE
|
||||
----------------
|
||||
✓ Architecture decisions (e.g., "chose PostgreSQL over MongoDB for ACID guarantees")
|
||||
✓ Bug fixes (e.g., "fixed race condition in auth middleware by adding mutex")
|
||||
✓ New features (e.g., "implemented JWT refresh token flow")
|
||||
✓ Refactorings (e.g., "extracted validation logic into separate service")
|
||||
✓ Discoveries (e.g., "found that API rate limit is 100 req/min")
|
||||
|
||||
✗ NOT routine operations (reading files, listing directories)
|
||||
✗ NOT work-in-progress (only completed work)
|
||||
✗ NOT obvious facts (e.g., "TypeScript file has types")
|
||||
|
||||
HOW TO STORE OBSERVATIONS
|
||||
--------------------------
|
||||
When you identify something worth remembering, output your observation in this EXACT XML format:
|
||||
|
||||
\`\`\`xml
|
||||
<observation>
|
||||
<type>feature</type>
|
||||
<text>Implemented JWT token refresh flow with 7-day expiry</text>
|
||||
</observation>
|
||||
\`\`\`
|
||||
|
||||
Valid types: decision, bugfix, feature, refactor, discovery
|
||||
|
||||
Structure requirements:
|
||||
- <observation> is the root element
|
||||
- <type> must be one of the 5 valid types (single word)
|
||||
- <text> contains your concise observation (one sentence preferred)
|
||||
- No additional fields or nesting
|
||||
|
||||
The SDK worker will parse all <observation> blocks from your response using regex and store them in SQLite.
|
||||
|
||||
You can include your reasoning before or after the observation block, or just output the observation by itself.
|
||||
|
||||
EXAMPLE
|
||||
-------
|
||||
Bad: "Read src/auth.ts file"
|
||||
Good: "Implemented JWT token refresh flow with 7-day expiry"
|
||||
|
||||
Wait for tool observations. Acknowledge this message briefly.`;
|
||||
}
|
||||
|
||||
/**
|
||||

|
||||

|
||||
export function buildObservationPrompt(obs: Observation): string {

|
||||
|
||||
Input:
|
||||
${JSON.stringify(JSON.parse(obs.tool_input), null, 2)}
|
||||
|
||||
Output:
|
||||
${JSON.stringify(JSON.parse(obs.tool_output), null, 2)}
|
||||
|
||||
ANALYSIS TASK
|
||||
-------------
|
||||
1. Does this observation contain something worth remembering?
|
||||
2. If YES: Output the observation in this EXACT XML format:
|
||||
|
||||
\`\`\`xml
|
||||
<observation>
|
||||
<type>feature</type>
|
||||
<text>Your concise observation here</text>
|
||||
</observation>
|
||||
\`\`\`
|
||||
|
||||
Requirements:
|
||||
- Use one of these types: decision, bugfix, feature, refactor, discovery
|
||||
- Keep text concise (one sentence preferred)
|
||||
- No markdown formatting inside <text>
|
||||
- No additional XML fields
|
||||
|
||||
3. If NO: Just acknowledge and wait for next observation
|
||||
|
||||
Remember: Quality over quantity. Only store meaningful insights.`;

|
||||
==============

|
||||
|
||||
FINAL TASK
|
||||
----------
|
||||
1. Review the observations you've stored this session
|
||||
2. Generate a structured summary that answers these questions:
|
||||
- What did user request?
|
||||
- What did you investigate?
|
||||
- What did you learn?
|
||||
- What did you do?
|
||||
- What's next?
|
||||
- Files read
|
||||
- Files edited
|
||||
- Notes
|
||||
|
||||
3. Generate the structured summary and output it in this EXACT XML format:
|
||||
|
||||
\`\`\`xml
|
||||
<summary>
|
||||
<request>Implement JWT authentication system</request>
|
||||
<investigated>Existing auth middleware, session management, token storage patterns</investigated>
|
||||
<learned>Current system uses session cookies; no JWT support; race condition in middleware</learned>

Structure requirements:
|

- <summary> is the root element
|

- All 8 child elements are REQUIRED: request, investigated, learned, completed, next_steps, files_read, files_edited, notes
|
||||
- <files_read> and <files_edited> must contain <file> child elements (one per file)
|
||||
- If no files were read/edited, use empty tags: <files_read></files_read>
|
||||
- Text fields can be multiple sentences but avoid markdown formatting
|
||||
- Use underscores in element names: next_steps, files_read, files_edited
|
||||
|
||||
The SDK worker will parse the <summary> block and extract all fields to store in SQLite.
|

|

Generate the summary now in the required XML format.`;
