playwright-skill

Complete browser automation with Playwright. Auto-detects dev servers, writes clean test scripts to /tmp. Test pages, fill forms, take screenshots, check responsive design, validate UX, test login flows, check links, automate any browser task. Use when user wants to test websites, automate browser interactions, validate web functionality, or perform any browser-based testing. Do NOT use for quick page debugging or network inspection (use chrome-devtools instead).

Quality

Content

65%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is highly actionable with executable scripts and a clear core workflow, but it is verbose through section duplication and lacks real bundle files for its progressive-disclosure references. Tightening the repeated guidance and providing the referenced API_REFERENCE.md would lift the weaker dimensions.

Suggestions

Remove the duplication between "CRITICAL WORKFLOW", "How It Works", and the Tips section so each guideline appears once at the point of use.

Actually provide API_REFERENCE.md (and ensure lib/helpers.js / run.js exist) so the progressive-disclosure references resolve, or drop the references and keep everything inline intentionally.

Add an explicit verification checkpoint to the workflow (e.g., confirm the dev server responded before writing/running the test script) to close the validation gap.

DimensionReasoningScore

Conciseness

Mostly efficient executable code, but the "How It Works" section duplicates the "CRITICAL WORKFLOW" and the Tips section reiterates detect-servers-first, /tmp, parameterized URLs, and visible-browser guidance already stated above; not score 3 because repetition pads the body, not score 1 because it avoids explaining basic Playwright concepts.

2 / 3

Actionability

Full copy-paste-ready scripts and exact commands ("cd $SKILL_DIR && node run.js /tmp/playwright-test-*.js") with parameterized URLs and env-var credentials; not the level below because the examples are complete and executable rather than pseudocode or partial.

3 / 3

Workflow Clarity

A numbered "CRITICAL WORKFLOW" with server-detection branching is present, but verification checkpoints are mostly implicit and the duplicated How-It-Works/Tips sections muddy the canonical path; not score 3 because there is no explicit validate-then-proceed feedback loop, not score 1 because the sequence is clearly ordered.

2 / 3

Progressive Disclosure

Sections exist and an API_REFERENCE.md link is signaled, but the body is a ~450-line monolith with six full inline code patterns, and the referenced files (API_REFERENCE.md, lib/helpers.js, run.js) are not present in the bundle; not score 3 because content is not appropriately split and references do not resolve, not score 1 because references are only one level deep and clearly signaled.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is specific, trigger-rich, and complete with both positive and negative use guidance in third-person voice. It clearly carves out a Playwright browser-automation niche distinct from chrome-devtools.

DimensionReasoningScore

Specificity

Lists many concrete actions — "Test pages, fill forms, take screenshots, check responsive design, validate UX, test login flows, check links" — matching the multiple-specific-actions anchor; not the level below because it goes well beyond naming a domain plus a few actions.

3 / 3

Completeness

Explicitly answers both what (the enumerated actions) and when ("Use when user wants to test websites..."), plus a negative trigger; not the level below because the when-clause is explicit, not implied.

3 / 3

Trigger Term Quality

Natural user phrasing is well covered ("test websites, automate browser interactions, validate web functionality, browser-based testing"); not the level below because it includes common variations rather than only a few relevant keywords.

3 / 3

Distinctiveness Conflict Risk

Clear Playwright niche with a "Do NOT use for quick page debugging or network inspection (use chrome-devtools instead)" disambiguation, making conflict unlikely; not the level below because it is distinguishable from adjacent skills rather than only somewhat specific.
