🚀 Usage Examples

Ask Claude (or any MCP client):

"Analyze this React project's architecture and suggest ADRs for any implicit decisions"

"Generate ADRs from the PRD.md file and create a todo.md with implementation tasks"

"Check this codebase for security issues and provide masking recommendations"

The server returns actual analysis results instead of prompts to submit elsewhere!

// Basic project analysis
const analysis = await analyzeProjectEcosystem({
  projectPath: '/path/to/project',
  analysisType: 'comprehensive',
});

// Generate ADRs from requirements
const adrs = await generateAdrsFromPrd({
  prdPath: 'docs/PRD.md',
  outputDirectory: 'docs/adrs',
});

// Smart Code Linking - Find code related to ADR decisions
const relatedCode = await findRelatedCode(
  'docs/adrs/001-auth-system.md',
  'We will implement JWT authentication with Express middleware',
  '/path/to/project',
  {
    useAI: true, // AI-powered keyword extraction
    useRipgrep: true, // Fast text search
    maxFiles: 10, // Limit results
    includeContent: true, // Include file contents
  }
);
