80%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.
The body is highly actionable with executable examples and excellent progressive disclosure via real one-level-deep reference files. It is held back by mild redundancy between the Critical Rules and Constraints sections and by a Test step that lacks explicit validation feedback loops for the cross-platform build/test process.
Suggestions
Consolidate the 'Critical Rules' and 'MUST DO / MUST NOT DO' sections — the overlapping items (Pressable, .get()/.set(), LegendList, expo-image) appear twice, costing tokens without adding guidance.
Strengthen the Test workflow step with explicit validation checkpoints and a feedback loop, e.g. 'run on both iOS and Android; if Perf Monitor drops frames or a crash appears, fix and re-verify before proceeding'.
Add a brief note distinguishing which 2026 architectural facts are stable guidance versus version-pinned specifics (e.g. SDK 53+, RN 0.79+), so time-sensitive entries don't silently decay.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Largely lean and assumes Claude's competence, but includes some minor redundancy — the MUST DO / MUST NOT DO list repeats constraints already stated in the Critical Rules section (Pressable vs Touchable, .get()/.set() vs .value, LegendList over ScrollView), and the 2026 architectural facts are partially restated later. | 4 / 5 |
Actionability | Provides copy-paste-ready executable code for the common cases — LegendList usage, native tabs, animated styles, expo-image — with concrete imports and props, plus explicit 'do/don't' pairs that leave no ambiguity about what to run. | 5 / 5 |
Workflow Clarity | The numbered Setup→Structure→Implement→Optimize→Test workflow is clear, but the Test step lacks explicit validation checkpoints or feedback loops, and the multi-platform build/test cycle for a production mobile app has no 'verify on both platforms before proceeding' gate despite batch/destructive risk in shipping changes. | 3 / 5 |
Progressive Disclosure | SKILL.md is a concise overview with a well-signaled Reference Guide table mapping each context to a one-level-deep reference file (performance-rules.md, expo-router.md, project-structure.md, platform-handling.md, storage-patterns.md), all of which exist in the bundle; navigation is easy and references stay a single level deep. | 5 / 5 |
