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 stays within token budget and is appropriately structured for its size. It loses points only on missing filter syntax and the absence of explicit validation checkpoints in the build/run/test loop.
Suggestions
Add the concrete test-filter syntax, e.g. 'swift test --filter MyTest' or '--filter MyTarget', so the 'test narrowly' step is copy-paste ready.
Insert an explicit validation checkpoint between build and run, e.g. 'If swift build fails, fix compile errors before running' or 'If swift test fails, classify the blocker before retrying'.
Optionally show one example failure-summary line per category so the 'Summarize failures' step is unambiguous.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Lean and efficient with no concept explanations Claude already knows; every line ('Use swift build by default', 'Use release mode only when the user explicitly needs it') earns its place. | 3 / 3 |
Actionability | Core commands (swift build, swift run <product>, swift test) are concrete and executable, but 'Apply filters when a specific test target or case is known' omits the filter syntax, leaving a key detail unspecified. | 2 / 3 |
Workflow Clarity | The five-step sequence is clearly ordered, but there are no validation/feedback checkpoints (e.g., build-fails-then-check-X before running), so checkpoints are only implicit. | 2 / 3 |
Progressive Disclosure | Under 50 lines with no bundle files and no need for external references; clear sections (Quick Start, Workflow, Guardrails, Output Expectations) satisfy the simple-skill anchor. | 3 / 3 |
