# File Watcher No-Index Test - Execution Report

## Summary

Test suite created to verify the fix for the "silent failure bug" where `start_file_watcher()` 
would fail silently if `semantic_index()` was not called first.

## Current Status: CANNOT RUN

### Issue
The `mcp_bridge.tools.semantic_search` module does not exist in the current codebase.

### Investigation Results

1. **Current Project State**
   - Location: `/Users/davidandrews/PycharmProjects/stravinsky`
   - Git repository was missing (`.git` directory deleted)
   - No `mcp_bridge` source directory present
   - Only documentation and config files exist

2. **Source Code Location**
   - Found via global stravinsky installation: `/opt/homebrew/bin/stravinsky`
   - Actual source: `/Users/davidandrews/PycharmProjects/claude-superagent/mcp_bridge`
   - `semantic_search.py` does not exist in that location either

3. **Missing Module**

## Test Suite Created

### File: `/Users/davidandrews/PycharmProjects/stravinsky/tests/test_file_watcher_no_index.py`

**Tests Implemented:**

1. **Test 1: No Index -> ValueError**
   - Ensures `start_file_watcher()` raises `ValueError` when no index exists
   - Verifies error message contains helpful keywords
   - Prevents silent failures

2. **Test 2: With Index -> Success**
   - Verifies normal workflow after creating index
   - Tests `semantic_index()` -> `start_file_watcher()` -> `stop_file_watcher()`
   - Validates watcher lifecycle

3. **Test 3: Error Message Quality**
   - Checks error message clarity
   - Validates actionable guidance
   - Ensures developer-friendly output

### Prerequisites Verified

✅ Ollama running and accessible
✅ nomic-embed-text model installed  
✅ chromadb package installed
✅ watchdog package installed

❌ mcp_bridge.tools.semantic_search module missing

## Next Steps

To complete this testing task, the following needs to happen:

### Option 1: Locate Existing Code
1. Find the actual `semantic_search.py` implementation
2. Verify it includes the `start_file_watcher()` fix
3. Copy it to the correct location
4. Re-run tests

### Option 2: Implement the Module
1. Create `mcp_bridge/tools/semantic_search.py` with:
   - `semantic_index(project_path, provider="ollama")` 
   - `semantic_search(query, n_results=5)`
   - `semantic_stats()`
   - `start_file_watcher(project_path, provider, debounce_seconds)`
   - `stop_file_watcher(project_path)`

2. Implement the critical fix:
   ```python
   def start_file_watcher(project_path: str, provider: str = "ollama", ...):
       # Check if index exists
       if not _index_exists(project_path):
           raise ValueError(
               f"No semantic index found for '{project_path}'. "
               f"You must run semantic_index() before starting the file watcher."
           )
       # ... rest of implementation
   ```

3. Run the test suite to verify

### Option 3: Verify on Different Branch
1. The code might exist on a different git branch
2. Check git history for when `semantic_search.py` was committed
3. Checkout the correct branch
4. Run tests

## Test Execution Command

Once the module exists:

```bash
cd /Users/davidandrews/PycharmProjects/stravinsky
uv run python tests/test_file_watcher_no_index.py
```

Expected output:
```
✅ ALL TESTS PASSED

The fix successfully prevents silent failures when start_file_watcher()
is called without first running semantic_index().
```

## Documentation Discrepancy

The README.md says:
> `start_file_watcher()` will show a warning but still work (indexes on first file change)

However, the requested fix is to **raise ValueError** instead. This is better practice because:

1. Fails fast with clear error
2. Prevents resource waste (starting watcher, waiting for file changes)
3. More explicit about requirements
4. Easier to debug

The README should be updated to reflect the ValueError approach.

## Files Created

1. `/Users/davidandrews/PycharmProjects/stravinsky/tests/test_file_watcher_no_index.py` (788 lines)
   - Comprehensive test suite
   - Prerequisite checks
   - 3 test scenarios
   - Clear output and error messages

2. `/Users/davidandrews/PycharmProjects/stravinsky/TEST_EXECUTION_REPORT.md` (this file)
   - Current state documentation
   - Next steps guidance
   - Investigation results

## Conclusion

The test infrastructure is ready and waiting for the `semantic_search.py` module to be 
created or located. Once that module exists with the proper ValueError fix, the tests 
will verify the bug is fixed.
