Repo Map

Codebase Map Generator

Generate a graph-ranked map of the codebase showing the most important files, dependencies, and call relationships.

What To Do

1. Analyze the repository structure: Use Glob to find all source files, count per directory, identify entry points.

2. Rank files by importance:

   • Fan-in (how many files reference this file) -- higher = more important
   • Fan-out (how many files this file imports) -- moderate = hub file
   • Size and change frequency via git log
   • Entry points (Controllers, Program.cs, App.tsx) rank highest

3. Generate the map as structured summary:

   ## Core (highest rank)
   src/backend/Program.cs                    -- Entry point, DI registration
   src/backend/Services/MatchingService.cs   -- Core matching algorithm (12 refs)
   
   ## API Layer
   src/backend/Controllers/CandidateController.cs -- 8 endpoints
   
   ## Domain
   src/backend/Models/CandidateProfile.cs    -- Central model (18 refs)
   

4. Focus mode: When --focus=<module>, zoom into that module with full dependency graph.

Arguments

• --depth=<n>: Directory tree depth (default: 2)
• --focus=<module>: Focus on specific module
• --format=<md|mermaid|json>: Output format
