    Cynical Sally

    Updated Aug 2026

    Cynical Sally is an AI code reviewer designed to counter the overly-agreeable tone of most AI pair programmers. Instead of cheerleading, she behaves like a brutally honest senior engineer: scoring your code on a 0-10 scale, citing specific lines, and explaining exactly why something is wrong before suggesting a fix. She ships as both a CLI and an MCP server, so the same reviews run inside Claude Code, Cursor, Windsurf, or directly in your terminal. Reviews are evidence-backed — every critique points to the file, line, and reasoning rather than vague 'consider refactoring' nudges — which makes her output useful as a real pre-commit gate rather than another rubber-stamp assistant. For developers using AI to generate large amounts of code, Cynical Sally is a no-nonsense second opinion that catches sloppy patterns before they reach review.
