72%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A tight, well-organized instruction skill that respects token budget and structure, but its workflow lacks explicit validation/retry checkpoints and its guidance omits the concrete commands needed to run focused tests. Strong on conciseness and disclosure.
Suggestions
Add the actual focused-rerun command syntax (e.g., `xcodebuild test -only-testing:Target/Class/test` or `swift test --filter`) so the guidance is copy-paste ready.
Insert an explicit validation checkpoint in the workflow (e.g., confirm the build compiles before running tests; rerun only failed tests to distinguish flakes from real failures).
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Lean and efficient with no padding or explanation of concepts Claude already knows; every section (Arguments, Workflow, Guardrails) earns its place. | 3 / 3 |
Actionability | The guidance is concrete (detect xcodebuild vs swift test, classify failures into named categories) but stops short of executable commands or examples for focused reruns (e.g., the actual -only-testing syntax), leaving key details missing. | 2 / 3 |
Workflow Clarity | Steps are clearly sequenced, but running a test suite is a batch operation and there is no explicit validation/retry checkpoint (e.g., confirm a successful build before testing, rerun only failures to confirm flakes), so workflow clarity is capped at 2. | 2 / 3 |
Progressive Disclosure | Under 50 lines, single-purpose, with no need for external references, and well-organized into Arguments/Workflow/Guardrails sections — meeting the simple-skill allowance for a top score with no bundle files. | 3 / 3 |
