Core agent-browser usage guide. Read this before running any agent-browser commands. Covers the snapshot-and-ref workflow, navigating pages, interacting with elements (click, fill, type, select), extracting text and data, taking screenshots, managing tabs, handling forms and auth, waiting for content, running multiple browser sessions in parallel, and troubleshooting common failures. Use when the user asks to interact with a website, fill a form, click something, extract data, take a screenshot, log into a site, test a web app, or automate any browser task.
npx skills add friday-platform/friday-studio --skill skill --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# agent-browser core Fast browser automation CLI for AI agents. Chrome/Chromium via CDP, no Playwright or Puppeteer dependency. Accessibility-tree snapshots with compact `@eN` refs let agents interact with pages in ~200-400 tokens instead of parsing raw HTML. Most normal web tasks (navigate, read, click, fill, extract, screenshot) are covered here. Load a specialized skill when the task falls outside browser web pages — see [When to load another skill](#when-to-load-another-skill). ## The core loop ```bash agent-browser open <url> # 1. Open a page agent-browser snapshot -i # 2. See what's on it (interactive elements only) agent-browser click @e3 # 3. Act on refs from the snapshot agent-browser snapshot -i # 4. Re-snapshot after any page change ``` Refs (`@e1`, `@e2`, ...) are assigned fresh on every snapshot. They become **stale the moment the page changes** — after clicks that navigate, form submits, dynamic re-renders, dialog opens. Always re-snapshot before your next ref interaction. ## Quickstart ```bash # Install once npm i -g agent-browser && agent-browser install # Take a screenshot of a page agent-browser open https://example.com agent-browser screenshot home.png agent-brow

How do I install it?
Run `npx skills add friday-platform/friday-studio --skill skill --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From friday-platform/friday-studio, a repository with 98 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
