SigMap

Ranks codebase files against a natural language query using TF-IDF, extracts function and class signatures from the top matches, and generates compact context files for AI assistants.

What you can do

  • Query-driven file ranking: Ask "Where is auth handled?" and get the top 5 most relevant files with relevance scores.
  • Token reduction: Compress 80K+ token repos down to 2K-4K tokens with 40-98% reduction.
  • Adapter outputs: Generate CLAUDE.md, .cursorrules, copilot-instructions.md, AGENTS.md, and more.
  • Validation: Confirm the right files are in scope before a big refactor or debug session.
  • Groundedness scoring: Judge whether an AI response is grounded in actual codebase context.
  • MCP server: 9 on-demand tools for Claude Code and Cursor integration.
  • Zero dependencies: Works offline with no external services.

Prerequisites

npm install -g sigmap
sigmap --health

Or use without installing: npx sigmap

Example Requests

  • "Run sigmap to generate a CLAUDE.md for this repo."
  • "Ask sigmap which files handle payment processing."
  • "Validate that the right files are in scope for this auth refactor."
  • "Set up sigmap as an MCP server for Claude Code."

Regenerate context files after major structural changes to keep AI answers accurate.
