82%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.
The body is a lean, well-organized set of testing principles that assumes competence and gives concrete, directive rules with a clear TDD workflow and verification steps. Its main limitation is the absence of worked examples that would make the guidance fully concrete for an instruction-only skill.
Suggestions
Add one or two short worked examples (e.g., a tiny Arrange-Act-Assert test and a mock-at-I/O-boundary snippet) to lift actionability toward fully executable guidance.
Include a brief checklist for the TDD cycle and regression-test addition so the workflow has an explicit feedback/re-run checkpoint beyond the VERIFY step.
Consider splitting the Data Layer Testing detail into a short reference section or file if the skill grows, to keep the overview lean.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense, principle-driven, and free of padding or basic concept explanations (e.g., it never explains what a test is); every line states a rule that earns its place, assuming Claude's competence. | 5 / 5 |
Actionability | Guidance is concrete and directive ("Structure each test as Arrange, one Act, and Assert", "Mock direct external I/O boundaries", "Each test creates and cleans up its own state"), but as an instruction-only skill it lacks illustrative examples that would push it to fully copy-paste-ready clarity. | 4 / 5 |
Workflow Clarity | The TDD cycle is explicitly sequenced with a verify checkpoint ("RED ... GREEN ... REFACTOR ... VERIFY: run the repository's applicable regression checks"), and regression guidance includes re-running characterization evidence; the overall skill is a principle collection rather than one workflow, so it stops short of the checklist-driven 5. | 4 / 5 |
Progressive Disclosure | Content is organized into clearly labeled sections (TDD, Quality Requirements, Test Design Rules, Mock and Boundary Rules, Data Layer Testing, Verification Requirements, Test Organization, Regression Testing) with no nested references and appropriate single-level structure; it sits at the boundary of the simple-skill exception rather than cleanly qualifying for 5. | 4 / 5 |
