88%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.
A strong, highly executable skill body: concrete code, exact dependencies, a sequenced workflow with validation and a test-failure decision procedure, and a verified one-level reference. The main improvement opportunities are trimming the version-branching and Coverage Check prose and moving the bulk of the inline API tables into a second reference file.
Suggestions
Move the Filters, Terminal Operators, Built-in Testers, and Assertions Reference tables into a references/ file (e.g. references/query-api.md), keeping only 2-3 key examples inline so SKILL.md stays a lean overview.
Condense the version-branching guidance (Vaadin 25.1 vs 25.2, find() vs $()) into a single short 'Version differences' note, leaving detailed per-version API notes to a reference.
Trim the Coverage Check section's rationale paragraphs to the essential instruction (hand off to /coverage-check, do not run the audit here) — the 'triple audit / takes minutes' justification can be one line.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense with high-value, project-specific guidance and almost no explanation of concepts Claude already knows, but version-branching prose (Vaadin 25.1 vs 25.2, find() vs $()) and the multi-paragraph Coverage Check rationale ('Running the audit here would triple it... takes minutes') could be trimmed or consolidated. Not 5 because these passages spend tokens on justification rather than instruction; not 3 because there is no padding and every section carries actionable information. | 4 / 5 |
Actionability | Fully executable throughout: copy-paste code for navigation, find(), test(), Grid, notifications, and ConfirmDialog; exact Maven coordinates per version; the complete UseCase annotation source; filter/terminal-operator/tester tables; and a concrete 10-step workflow. Specific examples cover the common cases (e.g. 'test(find(TextField.class).withCaption("Name").single()).setValue("John")'). | 5 / 5 |
Workflow Clarity | The 10-step Workflow is clearly sequenced with explicit validation checkpoints ('Run tests to verify they pass', 'Run the whole test class afterwards') and a genuine error-recovery feedback loop in 'When a Test Fails' that branches on whether the test mechanics or the spec-vs-code value is wrong, including what not to do (no weakening, no @Disabled). Bootstrap checks (existing UseCase annotation, existing test class) act as a checklist. | 5 / 5 |
Progressive Disclosure | Good structure with a well-signaled, one-level-deep reference (references/UC001ManagePersonsTest.java.md, verified to exist, with its role explained and a path-resolution note). Not 5 because the ~150 lines of Common Patterns, filters/terminal-operator/tester tables, and Assertions Reference are inline API reference that could largely live in a second reference file to keep SKILL.md an overview; not 3 because the single reference that is provided is clearly signaled and content is organized under clean headers. | 4 / 5 |
