agent-browser

Browse the web for any task — research topics, read articles, interact with web apps, fill forms, take screenshots, extract data, and test web pages. Use whenever a browser would be useful, not just when the user explicitly asks.

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 highly actionable, well-structured CLI reference that leads with a quick-start, groups commands logically, and pairs them with worked examples. Its standout is the explicit bounded-wait guidance with recovery steps, demonstrating strong workflow discipline for a tool prone to hanging.

DimensionReasoningScore

Conciseness

The body is mostly lean command tables with inline comments and no padding of concepts Claude already knows, though the bounded-wait section and several per-command comment restatements add a little that could be trimmed.

4 / 5

Actionability

Every command is concrete, copy-paste ready, and the worked form-submission and data-extraction examples cover common end-to-end cases with real refs and values.

5 / 5

Workflow Clarity

A clear numbered core workflow is followed by an explicit bounded-wait pattern with wall-clock timeout AND max-attempts, plus timeout-recovery guidance (snapshot/screenshot, report, move on) — strong validation and feedback-loop discipline.

5 / 5

Progressive Disclosure

No bundle files exist, so the single well-organized SKILL.md with clear section headers fits the under-50-lines/simple-skill exception loosely; structure is clean and navigable with no nested references.

Description

85%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, third-person description that pairs a comprehensive action list with an explicit proactive usage trigger. It is concise, concrete, and clearly answers both what and when, with only minor synonym coverage and overlap-risk gaps.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'research topics, read articles, interact with web apps, fill forms, take screenshots, extract data, and test web pages' — giving comprehensive coverage of the browser tool's capabilities.

5 / 5

Completeness

Explicitly answers both what it does (the action list) and when to use it via the 'Use whenever a browser would be useful, not just when the user explicitly asks' clause with concrete trigger framing.

5 / 5

Trigger Term Quality

Natural user-facing terms like 'browse the web', 'research topics', 'read articles', 'fill forms', and 'take screenshots' are present, but it lacks synonym breadth and explicit file/extension-style variants for completeness.

4 / 5

Distinctiveness Conflict Risk

The browser-automation niche is fairly distinct and the proactive trigger narrows it, but the broad framing ('any task', 'whenever a browser would be useful') keeps some overlap risk with general web/research skills.
