Signature Map

Use this skill to navigate declarations before broad repo scans.

Runtime files

• scripts/sigmap
• scripts/generate-signatures.sh
• scripts/sigmapgen/main.go

Recommended workflow

1. Refresh once:

./scripts/sigmap refresh --root <repo_root>

2. Query declarations:

./scripts/sigmap name <SymbolName> --root <repo_root> --no-refresh
./scripts/sigmap search "<regex>" --field all --icase --root <repo_root> --no-refresh
./scripts/sigmap open "<relative/file::symbol>" --root <repo_root> --context 60 --no-refresh

3. Diagnose when needed:

./scripts/sigmap doctor --root <repo_root>

Use rg for call-site search; use sigmap for declaration lookup.
