Skill: lion504/agent-browser-core-1-0-1 (version 1.0.0)

--- name: agent-browser-core description: OpenClaw skill for the agent-browser CLI (Rust-based with Node.js fallback) enabling AI-friendly web automation with snapshots, refs, and structured commands. --- # Agent Browser Skill (Core) ## Purpose Provide an advanced, production-ready playbook for using agent-browser to automate web tasks via CLI and structured commands. ## Best fit - You need deterministic automation for AI agents. - You want compact snapshots with refs and JSON output. - You prefer a fast CLI with Node.js fallback. ## Not a fit - You require a full SDK or custom JS integration. - You must stream large uploads or complex media workflows. ## Quick orientation - Read `references/agent-browser-overview.md` for install, architecture, and core concepts. - Read `references/agent-browser-command-map.md` for command categories and flags. - Read `references/agent-browser-safety.md` for high-risk controls and safe mode rules. - Read `references/agent-browser-workflows.md` for recommended AI workflows. - Read `references/agent-browser-troubleshooting.md` for common issues and fixes. ## Required inputs - Installed agent-browser CLI and browser runtime. - Target URLs and workflow steps. - Session or profile strategy if authentication is required. ## Expected output - A clear command sequence and operational guardrails for automation. ## Operational notes - Snapshot early, act via refs, then snapshot again after DOM changes. - Use `--json` for machine parsing and scripting. - Use waits and load-state checks before actions. - Close tabs or sessions when done to release resources. ## Safe mode defaults - Do not use `eval`, `--allow-file-access`, custom `--executable-path`, or arbitrary `--args` without explicit approval. - Avoid `network route`, `set credentials`, and cookie/storage mutations unless the task requires it. - Allowlist domains and block localhost or private network targets. ## Security notes - Treat tokens and credentials as secrets. - Avoid `--allow-file-access` unless explicitly required.

> Note: Command availability can vary by version. Use `agent-browser help` to confirm.

## Safe defaults (typical)
- `open`, `click`, `dblclick`, `fill`, `type`, `press`, `hover`, `select`
- `check`, `uncheck`, `scroll`, `screenshot`, `snapshot`, `close`
- `back`, `forward`, `reload`
- `wait`, `wait --text`, `wait --url`, `wait --load networkidle`
- `get text`, `get html`, `get value`, `get attr`, `get title`, `get url`
- `find role`, `find text`, `find label`, `find placeholder`

## Sensitive / explicit approval
- `eval` (arbitrary JS execution)
- `download <selector> <path>` (writes to disk)
- `set credentials`, `cookies`, `storage` (stateful secrets)
- `network route` / `network requests` (traffic interception)
- `set headers`, `--proxy` (traffic manipulation)
- `--allow-file-access` (local file access)
- `--executable-path`, `--args`, `--cdp` (custom runtime control)

## Debug and state
- `trace start/stop`, `console`, `errors`, `highlight`
- `state save`, `state load` (treat state files as sensitive)

## Tabs and frames
- `tab`, `tab new`, `tab <n>`, `tab close`
- `frame <selector>`, `frame main`

content: # Agent Browser Overview

## 1) What it is
- A fast Rust-based headless browser automation CLI with a Node.js fallback.
- Designed for AI agents to navigate, click, type, and snapshot pages via structured commands.
- Uses a background daemon and Playwright for browser control.

## 2) Install and setup (hardened)
- Pin the version you trust:
  - `npm install -g agent-browser@<version>`
- Prefer a dedicated environment or container for installs.
- Avoid running with elevated OS privileges.
- Install browser runtime:
  - `agent-browser install`
- Linux dependencies (if needed):
  - `agent-browser install --with-deps`
  - or `npx playwright install-deps chromium`

## 3) Browser engines
- Chromium is the default browser engine.
- Firefox and WebKit are supported through Playwright.

## 4) Snapshot concept
- `snapshot` returns a structured view with stable element refs.
- Refs are designed for compact, deterministic automation.

## 5) Sessions
- The CLI supports multiple sessions so agents can isolate work.

## 6) Security posture
- Treat the CLI as high privilege; run with strict allowlists.
- Avoid file access and arbitrary script execution unless required.
- Keep profiles and state files ephemeral by default.

content: # Safety and Risk Controls

## High-risk capabilities
- `eval` (arbitrary JavaScript)
- `--allow-file-access` (local file access)
- `--executable-path`, `--args`, `--cdp` (custom runtime control)
- `network route` / `set headers` / `--proxy` (traffic manipulation)
- `set credentials`, cookies, storage, and state files (secret handling)

## Safe mode checklist
1. Allowlist target domains; block localhost and private networks.
2. Disallow `eval` unless explicitly required.
3. Disallow local file access unless explicitly required.
4. Avoid downloads and filesystem writes by default.
5. Use ephemeral sessions; avoid persistent profiles when possible.
6. Redact tokens in logs and outputs.

## Escalation policy
- Require explicit human approval before using any high-risk capability.
- Record the reason and scope of the approval (which URLs, which action).

## Supply-chain hygiene
- Pin CLI version and review upgrades.
- Install in a dedicated environment.
- Avoid running with elevated OS privileges.

content: # Troubleshooting

## CLI runs but no browser opens
- Run `agent-browser install` to download Chromium.
- On Linux, run `agent-browser install --with-deps` if dependencies are missing.

## Native binary not available
- The CLI falls back to the Node.js daemon automatically.
- Ensure Node.js is installed and available.

## Debugging
- Use `--headed` to see the browser UI.
- Use `--debug` for verbose logs.

## Instability in DOM targeting
- Resnapshot after any navigation or DOM changes.
- Prefer refs from `snapshot` over brittle CSS selectors.


path: references/agent-browser-workflows.md
content: # Agent Browser Workflows

## 1) Snapshot-first loop
1. `open <url>`
2. `snapshot -i` and extract refs
3. Act using refs: `click @e12`, `fill @e14 "text"`
4. `snapshot -i` again after DOM changes

## 2) JSON mode for agents
- Prefer `snapshot -i` and `--json` outputs for deterministic parsing.
- Keep a local map of ref -> intent.

## 3) Authentication and reuse
- Log in once and `state save`.
- Reuse with `state load` in later runs.
- Treat state files as secrets and rotate when needed.

## 4) Stability tips
- Wait for load state before actions: `wait --load networkidle`.
- Use `wait --text` or `wait --url` for dynamic flows.
- Prefer refs from `snapshot` over brittle CSS selectors.

## 5) Safe automation loop
- Validate URL against an allowlist before `open`.
- Avoid `eval` and file access unless explicitly approved.
- Prefer read-only operations when possible.
