extract-signatureslisted

## What This Does Runs `bash ${CLAUDE_PLUGIN_ROOT}/core/scripts/tools/extract-signatures.sh --file <path>` and returns method stubs only: names, parameters, return types, decorators. Method bodies are replaced with `// ...`. Supports TypeScript and PHP. Always reads live source — no cache. ## When to Use - "How is X structured?" or "What methods does X have?" - Before editing a file — pre-edit recon to understand the API contract - Need function/class signatures without reading full file bodies (~500–2k tokens per file vs full file cost) ## How to Use ```bash bash ${CLAUDE_PLUGIN_ROOT}/core/scripts/tools/extract-signatures.sh --file <path/to/file.ts> ``` Optional flags: - `--kind class|interface|function` — filter by symbol kind - `--repo <repo>` — scope to a specific repository ## Output Format ```typescript // auth.service.ts — signatures only export class AuthService { authenticate(userId: string, tenantId: string): Observable<AuthResult> refreshToken(token: RefreshToken): Observable<AccessToken> logout(): void } ``` Indented signature blocks, one class/interface per section, no method bodies. ## Constraints - NEVER read full files >200 lines without using this skill first - ALWAYS use this before editing a file with complex APIs - NEVER cache or reuse output — always re-run for fresh results - ALWAYS replace method bodies with `// ...` in output
