78%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 well-structured, code-first skill body with excellent progressive disclosure and a clear step sequence. Its main weaknesses are two API inaccuracies that break copy-paste executability (the nonexistent @Statistics annotation and the wrong global-config filename) and a missing failure-handling loop in the workflow.
Suggestions
Remove the `@Statistics` annotation from the Step 6 example — jqwik collects statistics via `Statistics.collect()` alone (verified against the jqwik user guide; only `@StatisticsReport` exists, and it controls report formatting), so the example as written will not compile.
Fix the global configuration guidance in Step 7: current jqwik reads @Property defaults from `junit-platform.properties` (legacy `jqwik.properties`), not `jqwik.config.properties` — and verify the exact property key names against the jqwik configuration docs.
Add a short failure-recovery note to Step 8 (e.g., on failure, inspect the shrunk counterexample and rerun with the reported seed via `@Property(seed = ...)`) to close the workflow's feedback loop.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is code-first and lean: each step is a short example plus 1-3 sentences of jqwik-specific API detail Claude cannot be assumed to know, with detail tables delegated to the reference. Minor trimmable tokens remain — the "(more than Hypothesis's 100 or proptest's 256)" cross-library aside and the repeated "Per [jqwik-home]" attribution phrases — so it is efficient-with-minor-trimmings rather than 'every token earns its place'. | 4 / 5 |
Actionability | Most examples are complete and copy-paste ready (Maven/Gradle snippets with pinned version, @Property/@ForAll example, @Provide custom arbitrary, Combinators usage, config table, mvn/gradle test commands). Two gaps keep it below fully-executable: Step 6 annotates the property with `@Statistics`, which does not exist in jqwik's API (collection is via `Statistics.collect()`; only `@StatisticsReport` exists, for formatting), so that example will not compile; and Step 7 names the global config file `jqwik.config.properties`, but jqwik reads defaults from `junit-platform.properties` (legacy `jqwik.properties`). | 4 / 5 |
Workflow Clarity | A clear 8-step sequence (install → basic property → constraints → custom generators → catalog → statistics → configuration → CI) where the final step supplies a runnable verification command (`mvn test` / `gradle test`). Not a 5 because there is no error-recovery feedback loop — no guidance on what to do when a property fails (read the shrunk counterexample, rerun with the reported seed), even though Step 7's seed mechanism provides the pieces. | 4 / 5 |
Progressive Disclosure | Well-signaled one-level-deep structure: the body keeps getting-started material inline and consistently delegates the constraint-annotation table, full Arbitraries catalog, anti-patterns, limitations, and version note to references/jqwik-reference.md, which exists and contains exactly those sections with no nested references. The References section at the bottom aids navigation. Verified against the actual bundle: the referenced path is real. | 5 / 5 |
