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 1-3

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

A lean, highly actionable CLI reference with clear workflows and a thoughtful bounded-wait safety pattern. Its one weakness is structure: everything is inline with no progressive disclosure, which is appropriate for a command reference but does not satisfy the highest rubric anchor.

Suggestions

Move the full command catalog (Interactions, Get information, Cookies & Storage, etc.) into a references/COMMANDS.md and keep SKILL.md as a quick-start overview with a one-level-deep link, to satisfy progressive disclosure.

If keeping commands inline, add a short 'Full reference' pointer at the top so the overview/navigation intent of the rubric is met even without splitting files.

DimensionReasoningScore

Conciseness

The body is overwhelmingly terse command references with one-line inline comments; the only prose section (bounded waits) conveys non-obvious operational failure modes Claude would not already know, so every token earns its place.

3 / 3

Actionability

Commands are fully executable and copy-paste ready ('agent-browser fill @e2 "text"', 'agent-browser snapshot -i'), with worked examples for form submission and data extraction rather than pseudocode.

3 / 3

Workflow Clarity

A clear 4-step core workflow with re-snapshot guidance, plus an explicit validation/feedback loop in the bounded-wait section (timeout, snapshot on TIMEOUT, report and move on rather than re-wait).

3 / 3

Progressive Disclosure

Content is well-organized into labeled sections, but the ~190-line body is entirely inline with no bundle files or one-level-deep references to split out the command catalog; the simple-skills (<50 line) exemption does not apply, matching the score-2 anchor where content that could be separate is inline.

Description

100%Weight 40%Scale 1-3

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 enumerates concrete capabilities and provides an explicit, broad usage trigger. It avoids vague fluff and clearly distinguishes the skill's niche.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'research topics, read articles, interact with web apps, fill forms, take screenshots, extract data, and test web pages' — matching the score-3 anchor far better than the single-action score-2 example.

3 / 3

Completeness

Explicitly answers both what (the enumerated web actions) and when ('Use whenever a browser would be useful, not just when the user explicitly asks'), which is the score-3 pattern with an explicit trigger clause.

3 / 3

Trigger Term Quality

Uses natural phrases a user would actually say ('Browse the web', 'read articles', 'fill forms', 'take screenshots', 'extract data', 'browser would be useful') with good coverage rather than technical jargon.

3 / 3

Distinctiveness Conflict Risk

Browser automation is a clear niche with distinct triggers, unlikely to fire for unrelated skills; the 'whenever a browser would be useful' framing scopes it cleanly.
