What it does

Agent Browser is an agent skill from OmniUltraX/omnipanel. Browser automation CLI for AI agents. Use when the user needs to inspect, test, or automate browser behavior: navigating pages, filling forms, clicking buttons, taking screenshots, extracting page data, testing web apps, dogfooding Open Design previews, QA, bug hunts, or reviewing app quality. Prefer local Open Design preview URLs unless the user explicitly asks for external browsing.

Its SKILL.md is about 1.5k 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: A single AI spanning the entire DevSecOps workflow. OmniPanel is your personal engineering operating system—where terminal, SSH, databases, Docker, monitoring, and AI work…

When your agent uses it

  • The user needs to inspect
  • Automate browser behavior: navigating pages
  • Clicking buttons
  • Taking screenshots

Example prompts

  • “/agent-browser”

Requirements

  • Node.js

Workflow steps

10 steps, taken from the first numbered list in SKILL.md.

  1. Verify agent-browser is installed.
  2. Redirect upstream docs to temp files; quote only relevant lines.
  3. Ensure CDP is reachable, starting Chrome with open -na if needed.
  4. Connect with agent-browser connect http://127.0.0.1:9223.
  5. Open the local preview URL.
  6. Snapshot before selecting elements.
  7. Use selectors/refs from the latest snapshot; do not guess.
  8. Re-snapshot after navigation or UI state changes.
  9. Capture one screenshot when visual confirmation matters.
  10. Report title, URL, key visible text, screenshot path, and any uncertainty.

What it can do on your machine

Read from SKILL.md and the folder at commit d0be677. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • rg
    • curl
    • npm

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

  • Network

    No URLs in SKILL.md. Its commands use curl and npm, which can reach the network depending on how they are called.

    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 1.5k tokens when it runs. Until then it costs about 100 tokens; SKILL.md has 402 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~100
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 402 words (~1,516 tokens).

“Use agent-browser for local Open Design preview validation: inspect rendered state, click/type when requested, and capture one screenshot when visual evidence matters. Keep the browser local-first unless the user explicitly asks for external browsing.”
