What it does
Agent Browser is an agent skill from HHU3637kr/skills. Headless browser automation for AI agents using agent-browser CLI. Use when Claude needs to automate web browsing, scrape web data, interact with web pages, fill forms, take screenshots, or perform any browser-based tasks. Supports reference-based element targeting, session management, and semantic locators.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `references/commands.md`, `references/troubleshooting.md` and `references/workflows.md`).
It sits in Productivity & Automation, covering Browser automation, Authentication and Forms and invoices.
When your agent uses it
- Claude needs to automate web browsing
- Scrape web data
- Interact with web pages
- Take screenshots
Example prompts
- “/agent-browser”
Requirements
- Python 3
- Node.js
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Open a page
- Get snapshot with refs
- Interact using refs
- Repeat as needed
What it can do on your machine
Read from SKILL.md and the folder at commit a2cccf6. 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
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
npmnpx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm and npx, 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 1.9k tokens when it runs, and up to ~9.6k if it reads all its reference files. Until then it costs about 81 tokens; SKILL.md has 402 words of instructions outside code blocks.
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); the scripts in this folder 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 (~1,928 tokens).
