75%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-crafted, opinionated decision-guide: every heuristic is concrete and AI-specific rather than restating general refactoring wisdom, and the quick-reference table plus 'Applying this skill' section make it easy to act on. Weaknesses are mild — some narrative prose could be tightened, the heuristics are restated three times, and a worked example would raise actionability further.
Suggestions
Trim the narrative framing (e.g. the two-reader-to-three-reader setup and 'like pulling teeth' metaphor) and drop one of the three restatements of the heuristics — the prose section, the table, or 'Applying this skill' — to tighten conciseness.
Add a short worked example walking one real split decision through the 'understood in isolation?' test to push actionability toward fully executable guidance.
Consider moving the 'Three placement calls' detail (barrels, types, tests) into a reference file, which would shrink SKILL.md below the ~50-line threshold and enable top progressive-disclosure marks.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Largely efficient, skill-specific guidance with no padding about basics Claude knows, but the narrative framing ('like pulling teeth', the two-reader-to-three-reader setup) and a third restatement of the heuristics in 'Applying this skill' are minor over-explanation that could be trimmed. Fits 'efficient; minor instances of over-explanation', not the every-token-earns-its-place anchor at 5. | 4 / 5 |
Actionability | Concrete, specific guidance throughout: the isolation test, a ~300-line threshold, exact import forms ('@/components/Card'), the 'Foo.tsx next to Foo.test.tsx' convention, and a situation→action table. As an instruction-only skill this is actionable without code, but it stops short of fully copy-paste-ready examples, matching 'mostly executable guidance... with minor gaps'. | 4 / 5 |
Workflow Clarity | 'Applying this skill' gives clear per-scenario sequences (deciding, reviewing, structuring new) with the isolation test acting as an explicit checkpoint, and the quick-reference table serves as a checklist. No validation/error-recovery loops are present, so it does not reach the 5 anchor. | 4 / 5 |
Progressive Disclosure | A single well-organized file with clear section headers, a summary table, and no external references — none are needed at this size. The rubric reserves 5 for sub-50-line skills or well-signaled one-level-deep references; at ~90 body lines this fits 'good structure; most content is appropriately placed' with only minor organization gaps. | 4 / 5 |
