dev-browser is a CLI skill for browser automation with persistent page state and sandboxed JavaScript scripts.
About
The dev-browser skill provides browser automation through a CLI that runs sandboxed JavaScript scripts with persistent page state. Triggers include navigating websites, filling forms, taking screenshots, extracting web data, testing web apps, logging into sites, and phrases like go to a URL, click on, fill out the form, scrape, or automate browser workflows. Installation uses npm install -g dev-browser followed by dev-browser install to set up the local browser environment. Usage defers to dev-browser --help for command discovery and script execution patterns. The tool targets agents and developers who need repeatable browser interactions without building a full Playwright or Puppeteer integration from scratch each session. Persistent page state lets multi-step flows continue across commands rather than restarting a clean browser every time. Because SKILL.md is intentionally minimal, agents should inspect CLI help output for subcommands, script APIs, and options at runtime rather than assuming undocumented flags.
