Commands

no-mistakes-rust-no-inline-tests <src_dir> [<src_dir>...]

Options:

• --src-max <lines>
• --test-max <lines>

Requires tokei and jq.

no-mistakes-rust-max-file-size is an alias for this command.

no-mistakes-agents-md-max-size [options] [<max_lines>] [<max_chars>]

Fails when AGENTS.md or CLAUDE.md files exceed the configured size limits. Defaults are 200 lines and 12000 characters.
