53%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 overview with genuinely useful decision matrices and explicit pointers to six real, one-level-deep reference files. Its weaknesses are verbosity from duplicated sections (performance targets appear twice, decision content twice), time-sensitive version/dates inline, and the near-total absence of executable code or commands — the skill tells rather than shows, leaving execution details entirely to the references.
Suggestions
Merge 'Performance Targets' and 'Performance Budgets' into a single section (and fold the 'Quick Decision Matrix' into the 'Framework Quick Comparison' table) to remove duplicated content.
Replace generic 'Actions' and description-only best-practice bullets with at least one concrete, runnable example per major workflow (e.g., a Fastlane command, a Detox config snippet, or a minimal MVVM folder scaffold).
Move time-sensitive version requirements (iOS 17 SDK, Android 15 API 35, 2024-2025 adoption stats) into the relevant reference files or a dedicated 'Current requirements' section, and use consistent 'references/<file>.md' paths in the navigation section.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is bullet-dense rather than padded prose, but it duplicates itself — 'Performance Targets' reappears nearly verbatim in 'Performance Budgets' (launch <2s, memory <100MB, 60 FPS), and the 'Quick Decision Matrix' overlaps the 'Framework Quick Comparison' table. It also embeds time-sensitive data ('Mandatory: iOS 17 SDK (2024), Android 15 API 35 (Aug 2025)', '2024-2025' labels) outside any old-patterns section, and inlines general-knowledge material (HIG/Material conventions) Claude already knows. Not a 2: sections are tight and scannable; not a 4: the duplication and dated stats need trimming. | 3 / 5 |
Actionability | Guidance names concrete tools and numbers (Detox, Appium, Fastlane, Zustand/Riverpod 3/StateFlow, <2s launch, 70% coverage), but there is no executable code, command, or config anywhere — every section describes rather than instructs, and actually building an app would still require the reference files. Not a 2: the decision matrices and named tooling are specific enough to act on; not a 4: nothing here is copy-paste runnable and key implementation details live only in references. | 3 / 5 |
Workflow Clarity | The 'Implementation Checklist' gives arrow-chained sequences for setup, architecture, features, and quality, so a sequence exists, but validation checkpoints are only implicit (the Quality checklist lists test types without any validate-before-proceed gates or error-recovery loops). Not a 2: sequences are well-defined and ordered; not a 4: there are no explicit checkpoints like 'verify build on real device before proceeding to store submission'. | 3 / 5 |
Progressive Disclosure | All six reference files exist, are one level deep, and are well signaled via the 'Reference Navigation' section with per-file descriptions plus inline 'See: references/...' pointers. Not a 5: path formats are inconsistent ('references/mobile-frameworks.md' vs bare 'mobile-ios.md'), and substantial content that belongs in references (Key Best Practices, Performance Budgets, Platform-Specific Guidelines) is inlined in SKILL.md, duplicating the bundle files. | 4 / 5 |
