87%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-structured, highly actionable skill body with executable code, a concrete record schema, and clean one-level-deep progressive disclosure. The main gap is workflow clarity: the numbered steps lack explicit validation checkpoints and error-recovery feedback for batch failure modes like missing artifacts or baselines.
Suggestions
Add explicit validation checkpoints to 'How to use' — e.g., fail fast with a clear message if a required runner artifact or the last-green main-branch baseline is missing before flattening records.
Make the worked example reuse gate_decision() (or at least apply the regression/warn triggers and delta computation) so the runnable script matches the full decision rule rather than only checking budget breaches.
Add a short feedback loop for the no-go path — e.g., on a no-go verdict, surface the offending records and the baseline diff so the CI failure is triageable without re-running the gate.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense and assumes Claude's competence — it never explains what k6/Lighthouse/Web Vitals/CI are — and every section (overview, when-to-use, how-to-use, record schema, decision rule, artifact format, worked example, anti-patterns, references) earns its place without concept-explaining padding. | 3 / 3 |
Actionability | Provides fully executable code — a complete gate_decision() function and a runnable run_perf_gate.py parsing real k6/Lighthouse artifacts — plus a concrete JSON record shape, field source table, and a markdown summary template, all copy-paste ready. | 3 / 3 |
Workflow Clarity | The 'How to use' section gives a clear 5-step sequence, but validation checkpoints are only implicit (the final gate verdict) and there is no error-recovery/feedback loop for batch failure modes such as a missing runner artifact or absent main-branch baseline, which the rubric flags for batch operations. | 2 / 3 |
Progressive Disclosure | SKILL.md is a well-organized overview with a real, one-level-deep bundle file (references/ci-wiring-and-metric-sources.md) signaled clearly in multiple places and a closing References section; deep CI wiring is appropriately split out rather than inlined. | 3 / 3 |
