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, token-efficient instruction skill: real commands, a sensible workflow with a failure-summarization step, and clear guardrails and output expectations. The main improvements are adding the concrete flags for test filtering and release builds, and an explicit retry loop after build or test failures.
Suggestions
Replace the vague "Apply filters when a specific test target or case is known" with the concrete syntax, e.g., "Use `swift test --filter <TestTarget>` or `--filter <TestCaseClassName>`".
Name the release-build flag explicitly ("`swift build -c release`") so the guidance is copy-paste executable rather than requiring the reader to recall the flag.
Add a brief feedback loop after the build/test steps (e.g., "If the build fails, fix the top blocker from the error output and rebuild before running or testing") to close the validation gap.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is a lean, 46-line set of imperative lists with no explanations of concepts Claude already knows, matching anchor 4. Not 5 because the Quick Start section ("Use this skill when `Package.swift` is the primary entrypoint...") restates the frontmatter description's trigger conditions — a minor instance of over-explanation that could be trimmed. | 4 / 5 |
Actionability | Concrete, real commands appear throughout ("Read `Package.swift`", "Use `swift build`", "Use `swift run <product>`", "Use `swift test`"), matching anchor 4. Not 5 because "Apply filters when a specific test target or case is known" and "Use release mode only when the user explicitly needs it" omit the actual flags (e.g., `swift test --filter <TestCase>`, `swift build -c release`), leaving minor execution gaps. | 4 / 5 |
Workflow Clarity | A clear five-step sequence (inspect → build → run → test → summarize failures) closes with an explicit failure taxonomy for diagnosis, matching anchor 4. Not 5 because there is no explicit validate-and-retry feedback loop (e.g., 'if the build fails, fix the reported module and rebuild'); not 3 because the destructive/batch validation cap does not apply and the sequence plus failure categories cover most checkpoints. | 4 / 5 |
Progressive Disclosure | The body is under 50 lines, cleanly sectioned (Quick Start, Workflow, Guardrails, Output Expectations), self-contained, and makes no references to external files — and no bundle directories exist. This meets the rubric's simple-skill exception allowing a 5 for well-organized sections without external references. | 5 / 5 |
