agent-browser

Browser automation CLI for AI agents. Use when the user needs to interact with websites, including navigating pages, filling forms, clicking buttons, taking screenshots, extracting data, testing web apps, or automating any browser task. Triggers include requests to "open a website", "fill out a form", "click a button", "take a screenshot", "scrape data from a page", "test this web app", "login to a site", "automate browser actions", or any task requiring programmatic web interaction.

What it does

Automates browser tasks by interacting with web pages through a CLI. It supports opening URLs, taking interactive snapshots of elements, filling forms, clicking elements, waiting for conditions, taking screenshots, and extracting data. It also includes features for session management, authentication flows, and diffing page states to verify changes.

How it works

Follows a core workflow: navigate with agent-browser open <url>, take a snapshot with agent-browser snapshot -i to obtain element refs (e.g., @e1, @e2), perform interactions using those refs (e.g., agent-browser fill @e1 "text", agent-browser click @e3), and re-snapshot after DOM changes. Commands can be chained with && to persist the browser session across commands. The Essential Commands section enumerates navigation, interaction, data retrieval, and wait operations as concrete commands, including options for scoping, taking screenshots, and generating PDFs. It supports advanced workflows like authentication with saved profiles, state persistence, and session management via named sessions. It also provides diffing capabilities to compare snapshots or pages, and includes security-related features like content boundaries and domain allowlists.

When to use it

Use when you need programmatic web interaction such as opening websites, filling forms, clicking buttons, taking screenshots, scraping data, testing web apps, or automating any browser task. Triggers include requests to open, fill, click, take a screenshot, scrape, test, login, automate, or other browser actions.

What it can touch

The skill declares tools under the allowed-tools: Bash(npx agent-browser:), Bash(agent-browser:). Interactions are performed via commands like agent-browser open, agent-browser fill, agent-browser click, agent-browser snapshot, agent-browser screenshot, agent-browser diff, and related CLI options. It also references managing sessions, authentication, and state files.

Caveats

License is MIT. Security features are opt-in, and there are guidance sections for content boundaries, domain allowlists, and action policies. Refs become invalid when navigation occurs and require re-snapshotting. There are environment-variable and policy-based configurations noted for advanced usage.

From the SKILL.md

# Browser Automation with agent-browser ## Core Workflow Every browser automation follows this pattern: 1. **Navigate**: `agent-browser open <url>` 2. **Snapshot**: `agent-browser snapshot -i` (get element refs like `@e1`, `@e2`) 3. **Interact**: Use refs to click, fill, select 4. **Re-snapshot**: After navigation or DOM changes, get fresh refs ```bash agent-browser open https://example.com/form agent-browser snapshot -i # Output: @e1 [input type="email"], @e2 [input type="password"], @e3 [button] "Submit" agent-browser fill @e1 "user@example.com" agent-browser fill @e2 "password123" agent-browser click @e3 agent-browser wait --load networkidle agent-browser snapshot -i # Check result ``` ## Command Chaining Commands can be chained with `&&` in a single shell invocation. The browser persists between commands via a background daemon, so chaining is safe and more efficient than separate calls. ```bash # Chain open + wait + snapshot in one call agent-browser open https://example.com && agent-browser wait --load networkidle && agent-browser snapshot -i # Chain multiple interactions agent-browser fill @e1 "user@example.com" && agent-browser fill @e2 "password123" && agent-browser click

About this skill
What does the agent-browser skill do?

Browser automation CLI for AI agents. Use when the user needs to interact with websites, including navigating pages, filling forms, clicking buttons, taking screenshots, extracting data, testing web apps, or automating any browser task. Triggers include requests to "open a website", "fill out a form", "click a button", "take a screenshot", "scrape data from a page", "test this web app", "login to a site", "automate browser actions", or any task requiring programmatic web interaction.

How do I install it?

Run `npx skills add majiayu000/claude-skill-registry --skill agent-browser-coralshades-acm-ai --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 majiayu000/claude-skill-registry, a repository with 534 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.
