70%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 rigorous, well-sequenced analysis workflow with strong statistical hygiene, explicit validation checkpoints, rollback rules, and a complete output template — the workflow clarity is exemplary for an instruction-only skill. The main costs are length (a duplicated trigger list and a ~100-line inline report template) and the absence of any progressive disclosure: the output format and platform tables belong in reference files.
Suggestions
Remove or merge the 'Examples' section (lines 373–382), which nearly duplicates the 'When to Use This Skill' list (lines 27–36) — keep one trigger list.
Move the Phase 5 output template and the per-platform expected-columns tables into references/ files (e.g. OUTPUT_TEMPLATE.md, PLATFORM_FORMATS.md) linked from a short summary, cutting SKILL.md roughly in half.
Add a short executable snippet or named tool invocation for the statistical significance and sample-size calculations so the A/B guidance is copy-paste ready rather than directive-only.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense with domain-specific guidance and never explains concepts Claude already knows, but the ~100-line Phase 5 output template and placeholder-heavy tables inflate length, and the 'Examples' section duplicates the 'When to Use This Skill' trigger list almost verbatim — matching 'mostly efficient but could be tightened'. | 3 / 5 |
Actionability | Concrete, executable guidance throughout: per-platform expected columns, the CAC formula, a pre-registered statistical-test spec (alpha, power, MDE, stopping rule), rollback criteria, a full report template, and an exact output filename convention. Minor gaps remain — e.g. the statistical calculations are directed ('use a justified bootstrap or model') without any snippet or command — so it is mostly rather than fully executable. | 4 / 5 |
Workflow Clarity | The Phase 0→5 sequence is explicit with real validation checkpoints at each stage: privacy masking before analysis, non-comparability marking, pre-registered A/B analysis decisions, stop/rollback rules on every budget scenario, changes gated as 'proposals unless separately authorized', and monitor→re-evaluate feedback loops plus checklists in the action plan — matching the anchor for explicit validation, feedback loops, and checklists. | 5 / 5 |
Progressive Disclosure | No bundle files exist; everything is inline in a single ~370-line file. Sections are well organized, but the Phase 5 output template and per-platform format tables are natural candidates for separate reference files that are not split out, fitting 'content that should be separate is inline'. It is not a 2 because structure and headers are clear and nothing is buried. | 3 / 5 |
