92%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A compact, highly actionable reference: lean prose, copy-paste executable command examples for every option, and a clear preferred-to-fallback structure with a flagged compilation precondition. The only weakness is that the >50-line single file does not progressively disclose any detail into separate bundle files.
Suggestions
Move the per-option command reference (the '--run', '--grep', '--runGlob', '--coverage', '--timeout' subsections) into a references file such as test-options.md, leaving SKILL.md as a concise overview that links to it for the full option catalog.
Add one concrete, executable runTests tool example (e.g. a real tool invocation with files and testNames parameters) so the preferred path is as copy-paste ready as the shell fallback.
Consider a short 'Prerequisites / verification' checklist at the top stating the VS Code - Build watch task must be running, so the compilation requirement reads as an explicit pre-run validation checkpoint rather than a closing note.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean: mostly executable commands and examples with minimal prose, assuming Claude knows Mocha/Electron. Non-obvious clarifications (e.g. that --runGlob targets compiled .js) earn their tokens, fitting the 'every token earns its place' anchor. | 3 / 3 |
Actionability | Shell examples are copy-paste executable for every option with real paths, and the only non-executable example (runTests) is explicitly flagged '(conceptual)' so its flexibility is justified, matching the 'fully executable, copy-paste ready' anchor. | 3 / 3 |
Workflow Clarity | A single unambiguous task with a clear preferred (runTests) -> fallback (shell scripts) -> options structure, plus an explicit compilation precondition and stale-output pitfall. Operations are non-destructive, so the absence of a feedback loop does not cap the score. | 3 / 3 |
Progressive Disclosure | Well-sectioned with easy navigation and a one-level cross-reference to the integration-tests skill, but at ~100 lines it is a single monolithic file with no content split into bundle files. The rubric's '<50 lines, sections-only is fine' exception does not apply and its rationale favors an overview pointing to detailed materials, so this fits the level-2 anchor better than level 3. | 2 / 3 |
