FAQ

Does it call an LLM or need an API key? No. Rules are pattern-based TypeScript in src/rules/, with no runtime dependencies.

Why exit code 2? Usage or git error (for example, two diff-source flags at once, which src/cli.ts rejects).

Where does config come from? --config, else .fakegreenrc.json, .fakegreenrc, or the fakegreen key in package.json.
