## 🔍 Gap Analysis

### 1. Missing Unit Tests

#### Quick Start Module
- ❌ **Error Handling**:
  - Invalid template YAML format
  - Missing template files
  - Permission errors during directory creation
  - Disk full errors
  - Empty/whitespace-only descriptions
- ❌ **Edge Cases**:
  - Very long project descriptions (>10K chars)
  - Special characters in project names
  - Templates with circular dependencies
  - Conflicting agent requirements
- ❌ **Template Validation**:
  - Missing required fields in templates
  - Invalid agent references
  - Invalid workflow references
  - Malformed tech_stack entries

#### Hybrid Orchestrator
- ❌ **Error Handling**:
  - API failures/network errors
  - Invalid model names
  - Token limit exceeded scenarios
  - Cost threshold rejection flows
- ❌ **Edge Cases**:
  - Empty task strings
  - Very long tasks (>100K chars)
  - Unicode/emoji in tasks
  - Tasks with only special characters
- ❌ **Integration**:
  - Interaction with parent AgentOrchestrator
  - Actual API calls (mocked, but not tested)
  - Model fallback behavior

#### Skills Manager
- ❌ **Error Handling**:
  - Malformed SKILL.md files
  - Skills directory doesn't exist
  - Permission errors reading skills
  - Corrupted cache
- ❌ **Edge Cases**:

  - Empty skill files
  - Skills with only comments
  - Circular skill dependencies
- ❌ **Performance**:
  - Cache hit rate testing
  - Memory usage with many skills
  - Concurrent access patterns

### 2. Missing Integration Tests

- ❌ **Quick Start + Hybrid**: Initialize project and run agent with hybrid orchestration
- ❌ **Hybrid + Skills**: Run agent with auto-model-selection and progressive skills
- ❌ **Full Pipeline**: Init → Recommend → Run → Cost estimation
- ❌ **CLI Integration**: Test actual command-line interface
  - `claude-force init` with various flags
  - `claude-force run agent` with all orchestration options
  - Error messages and exit codes
  - Interactive mode input/output

### 3. Missing Performance Tests

- ❌ **Load Testing**:
  - 1000+ templates matching performance
  - 100+ skills loading performance
  - Caching effectiveness
- ❌ **Memory Testing**:
  - Memory usage with large templates
  - Skill cache memory limits
  - Leak detection
- ❌ **Concurrency**:
  - Multiple agents running simultaneously
  - Shared skill cache thread safety

### 4. Missing Validation Tests

- ❌ **Data Integrity**:
  - Generated claude.json is valid JSON
  - Generated task.md is valid markdown
  - File permissions are correct
  - Directory structure is complete
- ❌ **Cross-Platform**:
  - Path separators (Windows vs Unix)
  - Line endings (CRLF vs LF)
  - File permissions (644 vs 755)
