Code quality fixer — format, lint, docstrings, dead code removal

Paste Python, JavaScript, or TypeScript code and get a clean, production-ready version back. Routes: (1) FORMAT — consistent indentation, quote style, trailing commas, blank line normalization (PEP 8 for Python, prettier-style for JS/TS); (2) LINT — flag common bugs: undefined vars, bare excepts, mutable default args, == vs ===, unused imports; (3) DOCSTRINGS — generate concise Google-style docstrings for every function/class that lacks one; (4) DEAD CODE — find unreachable code, unused variables, and commented-out blocks. One input: start with 'Task: format', 'Task: lint', 'Task: docstrings', or 'Task: deadcode' then paste the code. Deterministic stdlib analysis — no LLM, no network, your code never leaves the sandbox. Delivered in seconds.
