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-structured, domain-rich body: nearly everything is non-obvious App Store-specific data delivered via tables, with a clear five-step testing workflow, prioritization matrix, and concrete output templates. Weaknesses are minor — a placeholder sample-size calculation with no real formula, slight redundancy between the framework and test-idea tables, and no explicit loop for handling inconclusive tests.
Suggestions
Replace the fill-in sample-size template with an actual rule-of-thumb formula or a small worked example (e.g., 'required impressions per variant ≈ 16 × p × (1-p) / MDE² for 95% confidence') so Step 3 is executable rather than a placeholder.
Add a short 'If the test is inconclusive' branch to Step 5 (e.g., extend duration once, then fall back to the control and move to the next priority test) to close the error-recovery gap in the workflow.
Trim the 'You are an expert...' role-play opener and merge overlapping guidance between the Test Design Framework and the Common Test Ideas tables to tighten token efficiency.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dominated by dense tables and terse bullets carrying non-obvious domain facts (PPO limits, '35 custom product pages', '90% confidence minimum', '80% of users never scroll past the first 3 screenshots'), which is exactly what Claude doesn't already know. Minor trimmable padding remains — the role-play opener 'You are an expert in App Store product page optimization...' and partial overlap between the Test Design Framework and the Common Test Ideas tables — so it fits anchor 4 ('efficient; minor instances of over-explanation that could be trimmed') rather than anchor 5. | 4 / 5 |
Actionability | Guidance is concrete for an instruction-only skill: exact hypothesis template ('If we [change], then [metric] will [improve] because [reason]'), the App Store Connect click path ('Go to Product Page Optimization → Create a new test → Upload variant assets'), and a copy-paste Test Plan output template. It falls short of anchor 5 because the sample-size step is a fill-in placeholder ('Required sample per variant: ~[N] impressions') with no actual formula or worked example, leaving the key sizing step pseudocode-like. | 4 / 5 |
Workflow Clarity | The five-step Test Design Framework (Hypothesis → Variants → Sample Size → Run → Interpret) is clearly sequenced, with decision checkpoints like 'Aim for 95% confidence before making decisions', 'Monitor but don't stop early', 'Change ONE thing per test', and a results-interpretation sequence that feeds the next test and a 3-month roadmap. Not anchor 5: there is no explicit error-recovery loop (e.g., what to do when a test is inconclusive or significance is never reached), a minor validation gap characteristic of anchor 4. | 4 / 5 |
Progressive Disclosure | No bundle files exist (no references/, scripts/, or assets/ directories), so the skill is a single well-organized file with clear one-level section headers and a Related Skills section pointing to sibling skills (screenshot-optimization, metadata-optimization, app-analytics, aso-audit). The one external reference (app-marketing-context.md) is clearly signaled in the Initial Assessment. It is not a 5 because at ~220 lines the Common Test Ideas tables and expected-impact data are bulk detail that could arguably live in a one-level-deep reference file, a minor organization gap matching anchor 4. | 4 / 5 |
