agent-browser

agent-browser is a command for coding agents from zot24/skills. It costs 0 tokens per session (728 once invoked), scanned A, original, no licence file.

A command-line tool for controlling web browsers from an AI coding agent. A command-line tool is a program you run from a terminal by typing commands.

In plain words
What is it for?
Use it for browser automation tasks such as opening pages, interacting with websites, and checking web behaviour.
Why use it?
It lets an agent carry out browser tasks through a defined command interface instead of relying only on manual clicking.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add commands/zot24/skills/agent-browser
Clone the repo
git clone --depth 1 https://github.com/zot24/skills

Or install agent-browser, the plugin that ships this one along with the rest of its 1 skill, 1 command.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agent-browser scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
