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.
The body is a well-organized, lean instruction sheet with concrete commands, exact import paths, and a built-in verify-against-docs checkpoint, which is highly effective for a code-usage skill. Its main weaknesses are the fully-fragment code example and time-sensitive SDK-version pinning woven into the main guidance rather than isolated in a versioning section.
Suggestions
Make the Host/RNHostView example a complete, copy-paste-ready React component (wrapped in a function returning the JSX) so it is fully executable as written.
Move the SDK 55 scoping and versioned doc URLs into a dedicated 'SDK versions' or 'old patterns' section so the main guidance is version-stable and the version pin does not penalize conciseness.
Add brief error-recovery guidance (e.g., what to check when a SwiftUI tree does not render or the rebuild fails) to turn the implicit checkpoint into an explicit feedback loop.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and assumes competence — terse bullets, one compact code example, no conceptual padding (e.g., it never explains what SwiftUI is). It falls short of a 5 because it embeds time-sensitive version pinning ("apply to SDK 55 only" plus v55.0.0 URLs) outside any 'old patterns'/'deprecated' section, which the guidelines penalize; it is above a 3 because there is no unnecessary explanation to trim. | 4 / 5 |
Actionability | Concrete, executable guidance dominates: an exact install command ("npx expo install @expo/ui"), precise import paths, doc-fetch URL patterns per component, and the Host/RNHostView example with complete imports. It is not a 5 because the JSX example is a fragment without a component wrapper, so it is not fully copy-paste runnable as-is; it is above a 3 because nothing is pseudocode or high-level hand-waving. | 4 / 5 |
Workflow Clarity | The install → native rebuild → usage sequence is clear, and the "fetch its docs to confirm the API" instruction acts as an explicit checkpoint before using components. It is not a 5 because there is no error-recovery guidance (what to do when a rebuild fails or a View does not render) — the missing-view/modifier fallback only appears at the end as an aside; it is above a 3 because checkpoints are present and no destructive/batch operations apply. | 4 / 5 |
Progressive Disclosure | The skill is under 50 lines with no bundle files (references/, scripts/, assets/ are absent), and the content is organized into clear sections (Installation, Instructions) with one-level-deep, clearly signaled external doc references. Per the rubric's simple-skill exception, this earns the top anchor with well-organized sections alone. | 5 / 5 |
