What it does

Agent Browser is an agent skill from cafe3310/public-agent-skills. 为 Agent 设计的自动化浏览器 CLI 工具,也能操作 Electron 桌面应用。当需要与网站交互(包括页面导航)时使用

Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Productivity & Automation, covering Browser automation. The repository describes itself as: personal agent skills for better QoL. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Browser automation

Example prompts

  • “/agent-browser”

Requirements

  • Node.js
  • Pre-approved tools (allowed-tools): Bash(agent-browser:*), Bash(npx agent-browser:*)

What it can do on your machine

Read from SKILL.md and the folder at commit 6c45501. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash(agent-browser:*)
    • Bash(npx agent-browser:*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Agent Browser loads about 518 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 161 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~19
When it runs · the whole SKILL.md, loaded when a task matches
~518

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

agent-browser

Fast browser automation CLI for AI agents. Chrome/Chromium via CDP with accessibility-tree snapshots and compact @eN element refs.

Start here

This file is a discovery stub, not the usage guide. Before running any agent-browser command, load the actual workflow content from the CLI:

bash
agent-browser skills get core             # start here — workflows, common patterns, troubleshooting
agent-browser skills get core --full      # include full command reference and templates

The CLI serves skill content that always matches the installed version, so instructions never go stale. The content in this stub cannot change between releases, which is why it just points at skills get core.

Specialized skills

Load a specialized skill when the task falls outside browser web pages:

bash
agent-browser skills get electron          # Electron desktop apps (VS Code, Slack, Discord, Figma, ...)
agent-browser skills get slack             # Slack workspace automation
agent-browser skills get dogfood           # Exploratory testing / QA / bug hunts
agent-browser skills get vercel-sandbox    # agent-browser inside Vercel Sandbox microVMs
agent-browser skills get agentcore         # AWS Bedrock AgentCore cloud browsers

Run agent-browser skills list to see everything available on the installed version.

Why agent-browser

  • Fast native Rust CLI, not a Node.js wrapper
  • Works with any AI agent (Cursor, Claude Code, Codex, Continue, Windsurf, etc.)
  • Chrome/Chromium via CDP with no Playwright or Puppeteer dependency
  • Accessibility-tree snapshots with element refs for reliable interaction
  • Sessions, authentication vault, state persistence, video recording
  • Specialized skills for Electron apps, Slack, exploratory testing, cloud providers
