Every section earns its place with concrete examples and actionable patterns. No explanation of what tests are or how testing frameworks work—assumes Claude's competence throughout.

Provides concrete before/after code examples, specific naming patterns, clear tables showing bad vs good names, and executable Python code. The worked example is copy-paste ready and demonstrates the exact transformation expected.

Clear decision tree: try renaming first, then add docstring only if needed. The 'when a docstring earns its place' table provides explicit criteria. The output format gives a structured checklist for the review process.

Well-organized with clear sections progressing from naming → docstrings → inline comments → anti-patterns → output format. Content is appropriately sized for a single file with no need for external references.

Lists multiple specific concrete actions: 'names, docstrings, and comments that explain what behavior is being tested and why' - clearly describes the deliverables and their purpose.

Clearly answers both what ('Writes documentation for test cases — names, docstrings, and comments') and when ('Use when test names are test_1 through test_47, when tests fail and nobody knows what they mean, or when onboarding needs a readable test suite').

Includes natural terms users would say: 'test names', 'test_1 through test_47', 'tests fail', 'readable test suite', 'onboarding', 'docstrings', 'comments' - covers both problem descriptions and technical terms.

Highly specific niche focused on test documentation specifically, with distinct triggers like 'test_1 through test_47' and 'failing test tells you what broke' - unlikely to conflict with general documentation or testing skills.
