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.
A lean, well-structured procedure with unusually concrete targets and safety gating, but the steps stop short of executable guidance — no commands or scripts to actually run Lighthouse, k6, or HAR analysis. Adding the handful of missing commands would lift actionability without costing conciseness.
Suggestions
Add the actual commands for the key steps, e.g. the Lighthouse mobile-profile invocation, a minimal k6 ramp script, and how to capture/analyze the HAR, so each step is executable as written.
Define "the manifest's limits" (which manifest, where to find it, what the numeric limits are) since step 6 depends on it for approval compliance.
Specify how memory growth is measured in step 4 (tool or DevTools protocol) and add a feedback loop for breached thresholds (e.g., record the regression and file it against the exit criteria table).
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Every line carries a new instruction with concrete numbers ("LCP ≤ 2.5s, INP ≤ 200ms, CLS ≤ 0.1", "Fast 3G", "30 minutes") and no explanation of concepts Claude already knows — nothing to trim, matching the lean-and-efficient anchor. | 5 / 5 |
Actionability | Tools and parameters are named (Lighthouse, web-vitals, k6, HAR, Fast 3G) but no step is executable as written — no Lighthouse/k6 commands, no method for capturing HAR or measuring memory growth, and "the manifest's limits" is undefined — fitting the some-concrete-guidance-but-incomplete anchor; it is above 2 because specific tools and thresholds are given, below 4 because an executor must invent the actual commands. | 3 / 5 |
Workflow Clarity | A clearly numbered 7-step sequence with safety gates ("approved only", "(staging)") and an explicit exit-criteria checkpoint matches the clear-sequence/most-checkpoints anchor; it misses 5 because there are no per-step validation results or feedback loops (e.g., what to do when a p75 threshold is breached). | 4 / 5 |
Progressive Disclosure | The skill is under 50 lines, needs no external reference files (none exist in the bundle), and is organized into clean Procedure and Exit criteria sections, which the rubric's simple-skill guideline scores at 5; nothing that belongs in a separate file is inlined. | 5 / 5 |
