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.

A well-structured, highly actionable skill body with a clear verify-driven workflow and good progressive disclosure. The main trim opportunity is the inline Quick Reference table, which overlaps with the dedicated reference file.

Suggestions

Shorten the inline Quick Reference table to the most-used commands and defer the full list to references/command-reference.md to reduce token duplication.

DimensionReasoningScore

Conciseness

Largely lean and command-forward with minimal prose, but the 20-row Quick Reference table duplicates much of references/command-reference.md that already exists, so it could be trimmed; fits anchor 4 rather than 5.

4 / 5

Actionability

Fully executable, copy-paste-ready commands across many concrete scenarios (click, form fill, upload, zoom, drag, fuzz); matches the anchor-5 example.

5 / 5

Workflow Clarity

Explicit 'Look → Act → Verify' loop with re-screenshot validation checkpoints and stale-coordinate guidance forms a clear feedback loop; matches the anchor-5 example.

5 / 5

Progressive Disclosure

Well-organized sections with a single clearly-signaled, one-level-deep reference (references/command-reference.md) for full argument syntax; tutorial inline, bulk syntax external; matches the anchor-5 example.

Description

95%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.

A strong, specific description with explicit trigger guidance and a clear, distinctive niche. The only weakness is the second-person voice ('you need to'), which costs it the top specificity anchor per the rubric's voice rule.

Suggestions

Rephrase in third person to avoid the voice penalty, e.g. 'Use when visually interacting with a GUI' or 'Use when the user needs to visually interact with a GUI'.

DimensionReasoningScore

Specificity

Lists multiple concrete actions ('test buttons, fill forms, verify visual layouts, fuzz web pages, automate user flows, take screenshots, or perform end-to-end QA'), which is comprehensive, but the second-person phrasing 'Use when you need to' triggers the voice penalty, reducing the score by 1 from the anchor-5 match.

4 / 5

Completeness

Explicitly answers both 'what' (visually interact with a GUI) and 'when' via a concrete 'Use when you need to...' trigger clause; matches the anchor-5 example.

5 / 5

Trigger Term Quality

Comprehensive natural terms users would actually say — 'test buttons', 'fill forms', 'take screenshots', 'fuzz web pages', 'automate user flows', 'end-to-end QA' — with synonym coverage; matches the anchor-5 example.

5 / 5

Distinctiveness Conflict Risk

Clear niche — visual GUI interaction explicitly contrasted with shell/API — with distinct triggers and minimal overlap risk; matches the anchor-5 example.
