Problem Statement

Some MCP tools may have placeholder implementations or incomplete functionality that prevents comprehensive testing. Need to identify and implement any missing functionality to ensure all tests can pass with real implementations.

Solution Design

Audit Strategy

• Review all 26 tools for placeholder implementations
• Identify incomplete or stub functions
• Replace mock responses with real functionality
• Ensure no TODO or unimplemented macros remain

Tools to Audit

Priority 1 - Core Tools

• repository_stats: Verify comprehensive statistics
• trace_path: Ensure real path finding algorithms
• find_dependencies: Complete dependency analysis
• find_references: Full reference detection
• explain_symbol: Comprehensive symbol information
• search_symbols: Complete search with inheritance

Priority 2 - Analysis Tools

• analyze_complexity: Real complexity calculations
• trace_data_flow: Complete data flow analysis
• analyze_transitive_dependencies: Full transitive analysis
• trace_inheritance: Complete inheritance trees
• analyze_decorators: Real decorator analysis
• find_duplicates: Actual duplicate detection algorithms

Priority 3 - Advanced Analysis

• find_unused_code: Real unused code detection
• analyze_security: Actual security vulnerability detection
• analyze_performance: Real performance analysis
• analyze_api_surface: Complete API analysis

Priority 4 - Specialized Tools

• analyze_javascript_frameworks: Real framework detection
• analyze_react_components: Complete React analysis
• analyze_nodejs_patterns: Full Node.js pattern detection

Implementation Requirements

• No placeholder responses or mock data in production paths
• All functions perform their documented purpose
• Error handling for all failure modes
• Performance optimizations where needed
• Comprehensive output data structures

Quality Gates

• Zero TODO comments in production code
• All functions have real implementations
• Test coverage validates actual functionality
• Performance meets documented requirements
• Error scenarios properly handled

Success Criteria

• All 26 tools have complete, functional implementations
• Comprehensive test suite passes with real functionality
• No placeholder or stub code remains
• Performance requirements met with real implementations
