vfs Virtual Function Signatures -- extract exported function, class, interface, and type signatures from source code with bodies stripped. Why vfs? AI coding agents waste tokens by grepping or reading entire files just to find a function. vfs parses source via AST and tree-sitter, returning only the signatures -- a compact "table of contents" of any codebase. 60-70% fewer tokens per search. It works with any AI coding tool -- Cursor, Claude Code, Antigravity, Windsurf, Cline, Continue, Aider, Copilot, Zed, or your own scripts. No vendor lock-in. How It Works Given a Go project with thousands of lines, asking "where is the login handler?" traditionally means grepping or reading entire files. vfs gives you just the signatures: Each line tells you the file, line number, and full signature -- no function bodies, no imports, no noise. You (or your AI agent) can then read only the exact lines needed. This works across 13 languages: $ vfs ./frontend -f auth src/hooks/useAuth.ts:5: export function useAuth(): AuthContext src/components/LoginForm.tsx:12: export const LoginForm: Rea
