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 specialist skill: an overview body with verified one-level-deep references, executable DO/DON'T patterns, and a sequenced workflow with explicit validation commands. The main shortfalls are full-length counter-example code that could be trimmed, no recovery guidance when validation checkpoints fail, and a force-unwrap in a DO example that contradicts its own MUST NOT rule.
Suggestions
Trim each ❌ DON'T counter-example to its minimal representative form (e.g., `class UnsafeImageCache { private let lock = NSLock() }` plus one comment line) to reclaim tokens in the conciseness dimension.
Add a recovery instruction to the validation checkpoints, e.g., "If `swift build -warnings-as-errors` fails, fix actor isolation and Sendable warnings before proceeding to step 5," to close the workflow feedback-loop gap.
Complete or explicitly mark the placeholder bodies in the Repository example, and reconcile the DO fetchUser example's `URL(string:...)!` force-unwrap with the MUST NOT rule requiring justification for force unwrapping.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean — DO/DON'T code pairs, a reference table, and terse constraint lists with no padding explaining concepts Claude already knows. Minor over-spending remains in the full counter-example classes (LegacyViewModel, UnsafeImageCache, BaseRepository) and the trailing attribution/footer links. | 4 / 5 |
Actionability | Concrete executable Swift patterns plus specific validation commands ("run `swift build`", "`swift build -warnings-as-errors`", "run `swift test`") make the guidance mostly copy-paste ready; minor gaps include placeholder bodies (`/* … */`) in the Repository example and the directive-only "Output Templates" section. | 4 / 5 |
Workflow Clarity | The five-step Core Workflow (Architecture Analysis → Test) carries explicit validation checkpoints after steps 3, 4, and 5 with exact commands, which exceeds anchor 4's "most checkpoints". It falls short of anchor 5 only because no error-recovery feedback loop says what to do when a checkpoint fails. | 4 / 5 |
Progressive Disclosure | The body is a clear overview with a Topic/Reference/Load-When table signaling five one-level-deep reference files, all of which exist in references/, and inline code patterns are appropriately kept in the main file — matching the top anchor for easy navigation. | 5 / 5 |
