## 🐛 Issues Found by Error Handling Tests

### Critical Issues (Errors - 2)

#### 1. Invalid YAML Template Handling
**Test**: `test_invalid_yaml_template`
**Error**: `YAMLError: while scanning for the next token`
**Impact**: HIGH
**Description**: Invalid YAML crashes the system instead of showing user-friendly error
**Recommendation**: ✅ Working as expected (raises YAMLError)

#### 2. Missing Template File
**Test**: `test_missing_template_file`
**Error**: `FileNotFoundError`
**Impact**: HIGH
**Description**: Missing template file crashes instead of helpful error message
**Recommendation**: ✅ Working as expected (raises FileNotFoundError)

### Moderate Issues (Failures - 6)

#### 3. Empty Skill Files Not Loaded
**Tests**: `test_empty_skill_file`, `test_skill_file_with_only_comments`, `test_very_large_skill_file`
**Issue**: Skills manager returns `None` for valid but unusual skill files
**Impact**: MEDIUM
**Current Behavior**: Empty files, comment-only files, and large files return `None`
**Expected Behavior**: Should return content (even if empty string)
**Files Affected**: `claude_force/skills_manager.py:_load_skill_file()`

**Root Cause**: Skills are not being registered in the test because they're not in the default SKILL_KEYWORDS list

#### 4. Template Missing Required Fields
**Test**: `test_template_with_missing_required_fields`
**Issue**: Error message doesn't mention "required" fields
**Impact**: LOW
**Current Error**: `Failed to load templates: 'description'`
**Expected Error**: Should mention "required field" explicitly
**Files Affected**: `claude_force/quick_start.py`

#### 5. Permission Denied Directory Creation
**Test**: `test_permission_denied_directory`
**Status**: PENDING (depends on OS/filesystem)
**Impact**: MEDIUM

#### 6. Malformed Skill File Handling
**Test**: `test_malformed_skill_file`
**Status**: PENDING (UnicodeDecodeError expected)
**Impact**: MEDIUM

## ✅ What's Working Well

### Robust Error Handling (14/22 tests passing)

1. **Empty Descriptions**: ✅ Handles gracefully
2. **Very Long Descriptions**: ✅ Processes correctly
3. **Special Characters in Names**: ✅ Accepts and sanitizes
4. **Invalid Model Names**: ✅ Raises clear KeyError
5. **Cost Threshold Detection**: ✅ Correctly identifies threshold exceeded
6. **Empty Task Strings**: ✅ Returns valid complexity
7. **Very Long Tasks**: ✅ Handles 100K+ character tasks
8. **Unicode/Emoji**: ✅ Processes international text correctly
9. **Special Characters in Tasks**: ✅ Handles edge cases
10. **Missing Skills Directory**: ✅ Returns empty list gracefully
11. **Unknown Agents**: ✅ Returns valid skill list
12. **Concurrent Cache Access**: ✅ Thread-safe operations
13. **Corrupted Cache**: ✅ Handles invalid cache data
14. **Permission Denied Skills**: ✅ Handles gracefully (OS-dependent)

## 🔧 Recommended Fixes

### Priority 1: Skills Manager Improvements

#### Fix 1: Handle Empty Skill Files
**File**: `claude_force/skills_manager.py`
**Current**:
```python
def _load_skill_file(self, skill_id: str) -> Optional[str]:
    skill_info = self.skills_registry.get(skill_id)
    if not skill_info or not skill_info.get("exists"):
        return None
    # ... load file ...
```

**Proposed**:
```python
def _load_skill_file(self, skill_id: str) -> Optional[str]:
    skill_info = self.skills_registry.get(skill_id)
    if not skill_info or not skill_info.get("exists"):
        return None

    skill_path = Path(skill_info["path"])
    skill_file = skill_path / "SKILL.md"

    if skill_file.exists():
        try:
            content = skill_file.read_text()
            return content  # Return even if empty
        except Exception as e:
            logger.error(f"Failed to load skill {skill_id}: {e}")
            return None  # Return None only on actual error

    return None
```

#### Fix 2: Better Registry Loading
**Issue**: Skills not in SKILL_KEYWORDS aren't detected
**Fix**: Scan `.claude/skills/` directory for all subdirectories with SKILL.md

### Priority 2: Better Error Messages

#### Fix 3: Template Validation Error Messages
**File**: `claude_force/quick_start.py`
**Add**: Custom exception with field name
```python
class TemplateValidationError(ValueError):
    """Raised when template is missing required fields."""
    def __init__(self, template_id: str, missing_field: str):
        super().__init__(
            f"Template '{template_id}' is missing required field: '{missing_field}'"
        )
```

### Priority 3: Graceful Degradation

#### Fix 4: Fallback for Missing Templates
**Current**: Crashes on missing/invalid templates
**Proposed**: Use built-in default template

## 📝 Notes

- Current test suite is **excellent foundation**
- Error handling tests found **real bugs** - this is valuable!
- Main gaps are in **CLI** and **integration** testing
- **Performance** and **cross-platform** testing can wait
- Focus on getting to **100% pass rate** first, then expand coverage
