## What is SigMap?

SigMap extracts a compact **signature map** of your entire codebase — function names, class hierarchies, exported types — and writes it to `.github/copilot-instructions.md`. Every AI coding assistant reads that file as its first-message context.

This plugin brings SigMap into Neovim with commands, auto-run on save, a statusline widget, and `:checkhealth` integration.

```
Before SigMap: "I don't know your codebase — can you share some files?"
After SigMap:  "I can see your AuthService, UserRepository, 47 API routes…"
```

---

## What's new in v4.0

- Standalone release — independent version cycle from the SigMap CLI core
- Compatible with SigMap CLI v6.0 (graph-boosted retrieval, incremental sig cache)
- Install path corrected: `'manojmallick/sigmap.nvim'` (no `subdir` needed)
