92%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
An exemplary lean skill body: the red-green-refactor sequence, hard rules, and a verification checklist are all present with no wasted tokens, and test-quality detail is correctly deferred to a well-signaled single reference file. The only improvement space is adding a minimal worked example or command pattern for the test-run step.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The ~20-line body is lean and directive with zero padding and no re-explanation of concepts Claude already knows; every line states a rule, a step, or a verification, matching the 'every token earns its place' anchor. | 5 / 5 |
Actionability | For an instruction-only skill the rules are concrete and directive ('No production code without a failing test first', 'A bug fix starts with a test that reproduces the bug'), but there are no commands or worked examples of the cycle, so it stops short of the 'specific examples cover the common cases' anchor. | 4 / 5 |
Workflow Clarity | The opening line gives the explicit sequence ('Write the test first. Watch it fail. Write the minimal code to pass. Refactor with the tests green.'), 'watch it fail' and the full-suite check act as validation checkpoints, and the 'Before you say it is done' section is an explicit done-checklist with an error-recovery heuristic ('If the test is hard to write... simplify the interface'). | 5 / 5 |
Progressive Disclosure | The under-50-line body is well organized into Rules and a done-checklist, and its single reference (references/writing-good-tests.md, verified to exist) is clearly signaled with a conditional load trigger ('When writing or changing a test, read...') and is one level deep, matching the top anchor. | 5 / 5 |
