# PR Summary: Fix SDK Agent Missing Working Directory Context (CWD)
|
|
|
|
## Problem
|
|
The SDK agent lacked spatial awareness because working directory (CWD) information was captured at the hook level but deliberately not passed to the worker service. This caused:
|
|
- SDK agent searching wrong repositories
|
|
- False "file not found" reports even when files existed
|
|
- Inability to match user-requested paths to tool execution paths
|
|
- Inaccurate observations due to spatial confusion
|
|
|
|
## Solution
|
|
Added CWD propagation through the entire data pipeline from hook to SDK agent, enabling spatial awareness.
|
|
|
|
## Technical Changes
|
|
|
|
### Data Flow
|
|
```
|
|
PostToolUseInput.cwd → save-hook → Worker API → SessionManager → SDK Agent → Prompt XML
|
|
```
|
|
|
|
### Files Modified (8 source + 2 build artifacts + 2 docs)
|
|
1. `src/services/worker-types.ts` - Added `cwd?: string` to interfaces
|
|
2. `src/hooks/save-hook.ts` - Extract and pass CWD to worker
|
|
3. `src/services/worker-service.ts` - Accept CWD in observations endpoint
|
|
4. `src/services/worker/SessionManager.ts` - Include CWD in message queue
|
|
5. `src/services/worker/SDKAgent.ts` - Pass CWD to prompt builder
|
|
6. `src/sdk/prompts.ts` - Include `<tool_cwd>` in XML + spatial awareness docs
|
|
7. `tests/cwd-propagation.test.ts` - 8 comprehensive tests (NEW)
|
|
8. `docs/CWD_CONTEXT_FIX.md` - Technical documentation (NEW)
|
|
9. `CHANGELOG.md` - User-facing changelog entry
|
|
|
|
### Example Output
|
|
Before (no spatial awareness):
|
|
```xml
|
|
<tool_used>
|
|
<tool_name>ReadTool</tool_name>
|
|
<tool_time>2025-11-10T19:18:03.065Z</tool_time>
|
|
<tool_input>{"path":"src/index.ts"}</tool_input>
|
|
<tool_output>{"content":"..."}</tool_output>
|
|
</tool_used>
|
|
```
|
|
|
|
After (with spatial awareness):
|
|
```xml
|
|
<tool_used>
|
|
<tool_name>ReadTool</tool_name>
|
|
<tool_time>2025-11-10T19:18:03.065Z</tool_time>
|
|
<tool_cwd>/home/user/awesome-project</tool_cwd>
|
|
<tool_input>{"path":"src/index.ts"}</tool_input>
|
|
<tool_output>{"content":"..."}</tool_output>
|
|
</tool_used>
|
|
```
|
|
|
|
### Init Prompt Enhancement
|
|
Added "SPATIAL AWARENESS" section explaining:
|
|
- Tool executions include working directory (tool_cwd)
|
|
- Which repository/project is being worked on
|
|
- Where files are located relative to project root
|
|
- How to match requested paths to actual execution paths
|
|
|
|
## Testing
|
|
|
|
### Unit Tests
|
|
✅ 8 tests in `tests/cwd-propagation.test.ts` - all passing
|
|
- Interface definitions include cwd
|
|
- Hook extracts cwd from input
|
|
- Worker API accepts cwd
|
|
- SessionManager queues cwd
|
|
- SDK Agent passes cwd to prompts
|
|
- Prompt builder includes tool_cwd element
|
|
- End-to-end flow validation
|
|
|
|
### Build Verification
|
|
✅ All builds successful
|
|
- `plugin/scripts/save-hook.js` includes `cwd:s||""`
|
|
- `plugin/scripts/worker-service.cjs` includes `<tool_cwd>` element
|
|
- `plugin/scripts/worker-service.cjs` includes "SPATIAL AWARENESS" section
|
|
|
|
### Security Scan
|
|
✅ CodeQL: 0 vulnerabilities
|
|
|
|
## Benefits
|
|
|
|
1. **Spatial Awareness**: SDK agent knows which directory/repository it's observing
|
|
2. **Accurate Path Matching**: Can verify if requested paths match executed paths
|
|
3. **Better Observations**: Won't search wrong repositories or report false negatives
|
|
4. **Universal Model Support**: Works with Haiku, Sonnet, and Opus (no premium workaround needed)
|
|
|
|
## Backward Compatibility
|
|
|
|
- ✅ `cwd` is optional (`cwd?: string`) - no breaking changes
|
|
- ✅ Missing `cwd` handled gracefully (defaults to empty string)
|
|
- ✅ Existing observations without `cwd` continue to work
|
|
- ✅ No database migration required (CWD is transient, not persisted)
|
|
|
|
## Evidence from Issue
|
|
|
|
**Test Case**: User requested "Review and understand ai_docs/continuous-improvement/rules.md"
|
|
|
|
**Before Fix**:
|
|
1. File exists at `/Users/.../dev/personal/lunar-claude/ai_docs/...` ✅
|
|
2. Read tool successfully read the file ✅
|
|
3. SDK agent received tool executions but **no CWD** ❌
|
|
4. SDK agent searched **claude-mem repository** instead of lunar-claude ❌
|
|
5. Summary reported: "File does not exist" ❌
|
|
|
|
**After Fix**:
|
|
1. File exists at `/Users/.../dev/personal/lunar-claude/ai_docs/...` ✅
|
|
2. Read tool successfully read the file ✅
|
|
3. SDK agent receives tool executions **with CWD** ✅
|
|
4. SDK agent searches **correct repository (lunar-claude)** ✅
|
|
5. Summary accurate: "Reviewed rules.md in lunar-claude project" ✅
|
