dev-browser

Browser automation with persistent named pages via the dev-browser CLI. Use when users ask to navigate websites, fill forms, take screenshots, extract web data, test web apps, log into sites, or automate browser workflows. Trigger phrases include "go to [url]", "click on", "fill out the form", "take a screenshot", "scrape", "automate", "test the website", "log into", "open the browser", or any browser interaction request.

Quality

Content

93%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, highly actionable tool guide with executable examples and useful gotchas, respecting token budget while remaining copy-paste ready. The only gap is the absence of an explicit success-validation step in the workflow.

Suggestions

Add a brief verification step after the quick-start example (e.g., check `page.url()` or the snapshot return value) to give the workflow an explicit success checkpoint.

Consider noting how to confirm the daemon/page state before a non-trivial script (e.g., re-snapshot to refresh refs) as a lightweight validation loop.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence — it skips explaining what a browser/Puppeteer is and packs only install commands, a quick start, and terse gotchas, so every token earns its place (score-5 anchor).

5 / 5

Actionability

Provides copy-paste ready code in two executable forms (heredoc script and `-e` one-liner) covering getPage/goto/snapshot/click/waitForLoad/url, plus concrete install commands and specific gotchas, matching the fully-executable score-5 anchor.

5 / 5

Workflow Clarity

There is a clear sequence (install -> consult --help -> write script) and the gotchas act as guardrails, but no explicit validation/verification checkpoint for confirming a script succeeded, so it sits at the score-4 anchor rather than 5.

4 / 5

Progressive Disclosure

At under 50 lines with no need for external references (no bundle files present), the content is well-organized into install, quick-start, and gotchas sections, qualifying for the score-5 simple-skill exception.

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 exemplary: it states the tool's purpose concisely, lists concrete capabilities, and provides an explicit 'Use when...' clause with natural trigger phrases. It uses neutral third-person voice and is highly distinct from other skills.

DimensionReasoningScore

Specificity

Lists multiple concrete actions ("navigate websites, fill forms, take screenshots, extract web data, test web apps, log into sites, or automate browser workflows") with comprehensive coverage, matching the score-5 anchor.

5 / 5

Completeness

Explicitly states what ("Browser automation with persistent named pages via the dev-browser CLI") and when ("Use when users ask to..." with concrete trigger phrases), matching the score-5 anchor that requires both clearly and explicitly.

5 / 5

Trigger Term Quality

Includes natural phrases users actually say ("go to [url]", "click on", "fill out the form", "take a screenshot", "scrape", "log into", "open the browser") with synonym coverage, matching the comprehensive score-5 anchor.

5 / 5

Distinctiveness Conflict Risk

Tied to a specific named CLI ("dev-browser") with distinct browser-automation triggers, giving a clear niche and minimal conflict risk with other skills, matching the score-5 anchor.
