Quality

Content

82%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 highly actionable, lean CLI reference with a clear sequenced workflow and well-signaled one-level references. It falls just short of top marks on conciseness and workflow clarity due to minor redundancy and the absence of an explicit error-recovery feedback loop.

DimensionReasoningScore

Conciseness

The body is mostly lean command-reference tables and step blocks assuming Claude's competence; minor redundancy between Step 2's snapshot example and the quick-reference tables keeps it just short of a 5.

4 / 5

Actionability

Fully executable, copy-paste-ready commands cover common cases (open, snapshot -i -c, click @e2, fill @e3, screenshot), and the quick-reference tables enumerate the rest of the CLI surface.

5 / 5

Workflow Clarity

Steps 0–3 are clearly sequenced (check install → classify request → snapshot workflow → verify results) with a verification checkpoint in Step 3, but there is no explicit validate→fix→retry feedback loop for failed interactions.

4 / 5

Progressive Disclosure

Two real one-level-deep references (browser-automation.md, ai-snapshot-workflow.md) are clearly signaled in a functionality table, but the fairly extensive inline command tables could arguably live in a reference file, leaving minor organization gaps.

Description

66%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 specific and action-oriented with strong anti-trigger guidance, but it lacks an explicit positive 'Use when...' trigger clause, capping completeness. Distinctiveness is good thanks to the CLI-specific framing and exclusion list.

Suggestions

Add an explicit positive trigger clause such as 'Use when the user asks to open a page, click elements, fill forms, take screenshots, or check a web app's UI via the agent-browser CLI.'

Include a couple of natural synonyms (e.g. 'page inspection', 'UI testing') to broaden trigger-term coverage.

Tighten 'web-app checks' into concrete actions (e.g. 'verify page state', 'assert element text') to lift specificity toward a 5.

DimensionReasoningScore

Specificity

Names the domain (browser automation) and lists several concrete actions — 'navigation, forms, screenshots, scraping, and web-app checks' — but 'web-app checks' is slightly generic, leaving minor coverage gaps short of a 5.

4 / 5

Completeness

The 'what' is clearly stated ('Browser automation through the repo agent-browser CLI...'), but there is no explicit positive 'Use when...' clause — only an anti-trigger ('Do NOT load for...'), so the 'when' is weakly implied and capped per the guideline.

3 / 5

Trigger Term Quality

Includes natural terms users would say ('navigation, forms, screenshots, scraping') with good coverage, but lacks common synonyms/variants that would push it to a 5.

4 / 5

Distinctiveness Conflict Risk

The 'repo agent-browser CLI' niche plus explicit anti-triggers ('Do NOT load for: sharing URLs, embedding links, or editing screenshot files') make it mostly distinct, with minor overlap risk against the named Browser Use / Playwright alternatives.
