browser-testing

Drive real browsers via Chrome DevTools MCP: navigate pages, capture snapshots, run responsive checks, and collect console/perf traces. Use when the user mentions: 'validate UI change in Chrome', 'capture a screenshot', 'run responsive checks', or 'collect console logs'. Trigger terms: browser testing, DevTools, console logs, screenshot, responsive testing

Quality

Content

92%Weight 40%Scale 1-5

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

The body is a tight, well-structured operator guide with strong validation feedback loops and concrete tooling. The only gap is that a few tool signatures are abbreviated and no fully copy-paste runnable code blocks are provided.

Suggestions

Add complete argument shapes for click/type/wait_for (e.g. the exact { uid } payload) so every tool call is copy-paste ready.

Include one small fenced example of a full evaluate_script assertion to anchor the inline guidance.

Note that the testing-config.md reference lives outside the skill bundle, or move it into ./references/ so the link resolves within the skill.

DimensionReasoningScore

Conciseness

Lean and efficient — 'Screenshots are expensive. MAX 3 per session, reserved for failures' and a terse tool list assume Claude's competence; every token earns its place with no concept padding.

5 / 5

Actionability

Gives concrete tool names with argument shapes (e.g. navigate_page — { type: 'url', url }, evaluate_script — { function: '() => ...' }) and a specific edge case (?q=nonexistent), but click/type/wait_for lack full arg signatures and there are no copy-paste runnable fenced blocks, leaving minor gaps.

4 / 5

Workflow Clarity

A clearly sequenced workflow with explicit validation feedback loops ('any error: fix source, rebuild, reload, restart from navigate', 'Every test must pass before writing the updated result.json', 'Do not stop on partial green').

5 / 5

Progressive Disclosure

Well-organized sections under 50 lines with a single clearly signaled one-level reference (testing-config.md); no bundle files exist, so the simple-skill structure is appropriate and easy to navigate.

Description

100%Weight 40%Scale 1-5

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 concise, specific, and explicitly answers both what the skill does and when to use it, with natural trigger phrases and a distinct niche. It is a strong example of the form.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'navigate pages, capture snapshots, run responsive checks, and collect console/perf traces' — giving comprehensive coverage of the skill's capabilities.

5 / 5

Completeness

Clearly states both 'what' (drive real browsers, navigate, snapshots, responsive checks, console/perf traces) and 'when' via concrete 'Use when the user mentions…' trigger phrases.

5 / 5

Trigger Term Quality

Explicit quoted trigger phrases ('validate UI change in Chrome', 'capture a screenshot', 'run responsive checks', 'collect console logs') plus a trigger-terms list with synonyms (browser testing, DevTools, console logs, screenshot, responsive testing) cover natural user language comprehensively.

5 / 5

Distinctiveness Conflict Risk

A clear niche — browser automation via Chrome DevTools MCP — with distinct triggers and minimal overlap risk against other skills.
