Browser Test Skill

Run end-to-end browser tests on pages affected by a PR or branch changes using the agent-browser CLI.

Use agent-browser Only For Browser Automation

This workflow uses the agent-browser CLI exclusively. Do not use any alternative browser automation system, browser MCP integration, or built-in browser-control tool. If the platform offers multiple ways to control a browser, always choose agent-browser.

Use agent-browser for: opening pages, clicking elements, filling forms, taking screenshots, and scraping rendered content.

Platform-specific hints:

• In Claude Code, do not use Chrome MCP tools (mcp__claude-in-chrome__*).
• In Codex, do not substitute unrelated browsing tools.

Prerequisites

• Local development server running (e.g., bin/dev, rails server, npm run dev)
• agent-browser CLI installed (see Setup below)
• Git repository with changes to test
