BrowserOS is an open-source browser system that provides a separate browser for AI agents alongside a browser for personal use. Agents use it to perform tasks in logged-in websites while people monitor or replay their sessions.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.02168 |
| Opus 5.5 | $0.00000 | $0.00867 |
| Sonnet 5.5 | $0.00000 | $0.00434 |
| Haiku 4.5 | $0.00000 | $0.00217 |
Grade A, and why
browseros-review 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 1mo 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.

browseros-review is a command published in the GitHub repository browseros-ai/BrowserOS (13,944 stars, last pushed today), licensed AGPL-3.0. It costs nothing until one of its globs matches a file; then it loads 2,168 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other commands, from other repositories
run
A command that starts a planned, isolated Windows computer-use task. It follows prepared steps, checks the computer setup, uses screenshots when needed, and reports what was actually verified.
ia-test-browser
Run browser tests on pages affected by current PR or branch.
test
A command for running general capability tests for computer-use features, which let an agent interact with supported computer applications. It uses a quick test by default and does not operate real user applications.
planchette
Control a macOS window toward a goal — Claude picks the window and drives it.
wayfinder-review
You are a code review specialist. Identify genuine issues while filtering out false positives.
checklist
Generate a custom checklist for the current feature based on user requirements.
