## User Input

$ARGUMENTS
```

You **MUST** consider the user input before proceeding (if not empty).

## Goal

Analyze test failure reports, identify root causes, and fix implementation issues while preserving semantic protocol compliance.

## Operating Constraints

1. **USE CODER MODE**: Always switch to `coder` mode for code fixes
2. **SEMANTIC PROTOCOL**: Never remove semantic annotations ([DEF], @TAGS). Only update code logic.
3. **TEST DATA**: If tests use @TEST_ fixtures, preserve them when fixing
4. **NO DELETION**: Never delete existing tests or semantic annotations
5. **REPORT FIRST**: Always write a fix report before making changes

## Execution Steps

### 1. Load Test Report

**Required**: Test report file path (e.g., `specs/<feature>/tests/reports/2026-02-19-report.md`)

**Parse the report for**:
- Failed test cases
- Error messages
- Stack traces
- Expected vs actual behavior
- Affected modules/files

### 2. Analyze Root Causes

For each failed test:

1. **Read the test file** to understand what it's testing
2. **Read the implementation file** to find the bug
3. **Check semantic protocol compliance**:
   - Does the implementation have correct [DEF] anchors?
   - Are @TAGS (@PRE, @POST, @UX_STATE, etc.) present?
   - Does the code match the TIER requirements?
4. **Identify the fix**:
   - Logic error in implementation
   - Missing error handling
   - Incorrect API usage
   - State management issue

### 3. Write Fix Report

Create a structured fix report:

```markdown
# Fix Report: [FEATURE]

**Date**: [YYYY-MM-DD]
**Report**: [Test Report Path]
**Fixer**: Coder Agent

## Summary

- Total Failed Tests: [X]
- Total Fixed: [X]
- Total Skipped: [X]

## Failed Tests Analysis

### Test: [Test Name]

**File**: `path/to/test.py`
**Error**: [Error message]

**Root Cause**: [Explanation of why test failed]

**Fix Required**: [Description of fix]

**Status**: [Pending/In Progress/Completed]

## Fixes Applied

### Fix 1: [Description]

**Affected File**: `path/to/file.py`
**Test Affected**: `[Test Name]`

**Changes**:
```diff
<<<<<<< SEARCH
[Original Code]
=======
[Fixed Code]
>>>>>>> REPLACE
```

**Verification**: [How to verify fix works]

**Semantic Integrity**: [Confirmed annotations preserved]

## Next Steps

- [ ] Run tests to verify fix: `cd backend && .venv/bin/python3 -m pytest`
- [ ] Check for related failing tests
- [ ] Update test documentation if needed
```

### 4. Apply Fixes (in Coder Mode)

Switch to `coder` mode and apply fixes:

1. **Read the implementation file** to get exact content
2. **Apply the fix** using apply_diff
3. **Preserve all semantic annotations**:
   - Keep [DEF:...] and [/DEF:...] anchors
   - Keep all @TAGS (@PURPOSE, @LAYER, @TIER, @RELATION, @PRE, @POST, @UX_STATE, @UX_FEEDBACK, @UX_RECOVERY)
4. **Only update code logic** to fix the bug
5. **Run tests** to verify the fix

### 5. Verification

After applying fixes:

1. **Run tests**:
   ```bash
   cd backend && .venv/bin/python3 -m pytest -v
   ```
   or
   ```bash
   cd frontend && npm run test
   ```

2. **Check test results**:
   - Failed tests should now pass
   - No new tests should fail
   - Coverage should not decrease

3. **Update fix report** with results:
   - Mark fixes as completed
   - Add verification steps
   - Note any remaining issues

## Output

Generate final fix report:

```markdown
# Fix Report: [FEATURE] - COMPLETED

**Date**: [YYYY-MM-DD]
**Report**: [Test Report Path]
**Fixer**: Coder Agent
