71%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, token-efficient workflow guide with good verification habits, but it is entirely tool-agnostic prose: without a single example command or code snippet for any of the tools it names, Claude must improvise the actual mechanics. Best Practices also duplicates the step list and could be trimmed.
Suggestions
Add one or two copy-paste-ready command examples for the preferred tools, e.g. a playwright-cli navigation/snapshot invocation or the Playwright MCP tool call pattern, so the 'Detect Tool' and 'Interact' steps have concrete mechanics.
Add a brief error-recovery step to the workflow (e.g. what to do when an element reference is stale or the page fails to load: re-capture snapshot, retry once, then report), turning the existing verify-after-interact checkpoint into a full feedback loop.
Merge the Best Practices section into the steps (or cut it) — 'Clean Up', 'Prefer Structured Data', and 'Snapshot First' restate steps 3, 4, and 6 verbatim, so removing the duplication would tighten the skill without losing information.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean with no re-teaching of concepts Claude already knows, but the Best Practices section duplicates the steps almost verbatim ('Clean Up' repeats step 6, 'Prefer Structured Data' repeats step 3, 'Snapshot First' repeats steps 3-4) — minor trimmable redundancy that keeps it below the every-token-earns-its-place anchor. | 4 / 5 |
Actionability | Tactical guidance is concrete ('capture page state... accessibility snapshot', 'use element references from the snapshot', 're-capture page state to verify') but there are no executable commands anywhere — no example invocations of 'playwright-cli', Playwright MCP tools, or even the fallback ('Check what browser tools are available' says what, not how), leaving key execution details missing. | 3 / 5 |
Workflow Clarity | A clearly sequenced 6-step process with an explicit verification checkpoint ('After each interaction, re-capture page state to verify the result') and a fallback path in step 1, but no error-recovery loop (element not found, page load failure), which the 5 anchor requires. Browser interaction is not destructive/batch, so no cap applies. | 4 / 5 |
Progressive Disclosure | The skill is under 50 lines, self-contained with no external references needed, and organized into clear Overview / Instructions / Best Practices sections — per the rubric's simple-skill guideline, well-organized sections alone earn the top score. | 5 / 5 |
