browser-automation

Browser automation powers web testing, scraping, and AI agent interactions. The difference between a flaky script and a reliable system comes down to understanding selectors, waiting strategies, and anti-detection patterns. This skill covers Playwright (recommended) and Puppeteer, with patterns for testing, scraping, and agentic browser control. Key insight: Playwright won the framework war. Unless you need Puppeteer's stealth ecosystem or are Chrome-only, Playwright is the better choice in 202

Quality

Content

22%

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

This skill content appears to be severely truncated or incomplete. It establishes a persona and lists pattern names but provides no actual executable code, concrete examples, or complete guidance. The Sharp Edges table has placeholder 'Issue' text instead of actual issues, and solutions are just code comments without implementation. The skill fails to deliver on its promise of teaching browser automation.

Suggestions

Add complete, executable Playwright code examples for each pattern (e.g., show actual test isolation setup, user-facing locator usage, auto-wait implementation)

Fix the Sharp Edges table with actual issue descriptions and complete solution code, not just comment fragments

Remove the persona introduction paragraph - it adds no actionable value and wastes tokens

Add a Quick Start section with a minimal working example that demonstrates the core recommended approach

Dimension	Reasoning	Score
Conciseness	The content has some unnecessary persona framing ('You are a browser automation expert who has debugged thousands...') that doesn't add actionable value. The capabilities list is verbose. However, the patterns/anti-patterns sections are reasonably concise.	2 / 3
Actionability	The skill is severely lacking in concrete, executable guidance. Pattern names are listed but no actual code examples are provided. The Sharp Edges table has solutions that appear truncated (just comments like '# REMOVE all waitForTimeout calls' with no actual code). No copy-paste ready examples exist.	1 / 3
Workflow Clarity	There is no clear workflow or sequence of steps. The content describes concepts (Test Isolation Pattern, Auto-Wait Pattern) but doesn't explain how to implement them. No validation checkpoints or multi-step processes are defined.	1 / 3
Progressive Disclosure	The content has some structure with sections (Patterns, Anti-Patterns, Sharp Edges, Related Skills), but the Sharp Edges table appears malformed/truncated. No references to external files for detailed content. The organization exists but content within sections is incomplete.	2 / 3

Description

32%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

This description reads like introductory documentation rather than a skill selection guide. While it establishes the domain (browser automation with Playwright/Puppeteer) and provides context about framework choice, it lacks explicit trigger conditions and concrete action verbs. The description is also truncated (ends mid-word '202'), suggesting incomplete content.

Suggestions

Add an explicit 'Use when...' clause with trigger terms like 'automate browser', 'web scraping', 'Playwright', 'Puppeteer', 'headless', 'click buttons', 'fill web forms'

Replace conceptual language ('understanding selectors, waiting strategies') with concrete actions ('navigate pages, click elements, extract data, handle authentication, capture screenshots')

Remove the editorial commentary ('Playwright won the framework war', 'Key insight') and focus on actionable capability descriptions

Dimension	Reasoning	Score
Specificity	Names the domain (browser automation) and mentions some actions (web testing, scraping, AI agent interactions) but lacks concrete specific actions like 'click buttons', 'fill forms', 'capture screenshots'. The description focuses more on concepts (selectors, waiting strategies, anti-detection) than actionable capabilities.	2 / 3
Completeness	Describes what the skill covers (browser automation frameworks and patterns) but completely lacks a 'Use when...' clause or any explicit trigger guidance. The description reads more like documentation than selection criteria.	1 / 3
Trigger Term Quality	Includes relevant keywords like 'Playwright', 'Puppeteer', 'browser automation', 'web testing', 'scraping', but misses common user terms like 'headless browser', 'web crawler', 'automate website', 'click', 'navigate', or file extensions.	2 / 3
Distinctiveness Conflict Risk	The mention of Playwright and Puppeteer specifically helps distinguish it, but 'web testing' and 'scraping' could overlap with other testing or data extraction skills. The framework-specific focus provides some distinctiveness.	2 / 3
