Scan a file or directory for tests that cannot fail.

Reports tests that pass regardless of the behaviour of the code they claim to cover: assertions that are true by construction, tests with no assertion at all, empty bodies, and tests that are skipped while still appearing in the suite.

Python is analysed with the ast module and is exact. Rust and JavaScript/TypeScript use a brace-matching text scanner, which is a heuristic tuned to miss cases rather than invent them. Every finding carries a file and line so it can be checked directly.

Args: path: File or directory to scan. Build and dependency directories (target, node_modules, .venv, ...) are skipped automatically. include_skipped: Include tests marked skipped or ignored. These always run green because they do not run at all, but they are usually deliberate, so they are reported at info severity. max_findings: Cap on returned findings. The summary always counts every finding, including any beyond the cap.

List every rule the scanner applies, with a one-paragraph description of each.

Explain one rule: what it detects and how the finding is usually resolved.

Args: rule: A rule id as returned by list_rules or by a finding, for example self-referential-source.
