browser-use-agent

Instructions for using browser-automation capabilities to inspect pages, search content, manage tabs, extract data, download files, and interact with forms.

In plain words
What is it for?
It helps open and navigate pages, inspect HTML, click and type, select options, upload or download files, handle tabs, take screenshots, and run autonomous browser tasks.
Why use it?
It provides a defined approach for browser tasks when ordinary web access is not enough to complete an interaction.

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

browser-use-agent 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 2d 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.

Browser Use Agent

Purpose

Use this skill for Browser Use-style web automation: autonomous browser task attempts, page state inspection, DOM/HTML extraction, in-page search, tab/session handling, screenshots, downloads, PDFs, and form workflows.

Workflow

  1. Call browser_use_capability_map when deciding whether the Browser Use capability is native, delegated, or still a gap.
  2. Prefer Stram browser_live_* tools for observable navigation, extraction, forms, tabs, downloads, PDFs, and screenshots.
  3. Use browser_live_html when page structure or attributes are needed, browser_live_page_search for literal/regex page text search, and browser_live_find_elements for CSS-selected element lists with attributes.
  4. Re-observe after each state-changing browser action.
  5. Use browser_use_agent_run only after native tools fail repeatedly, a task needs Browser Use's autonomous planner, or the user explicitly asks to use Browser Use.
  6. When delegating, provide a precise task, max step budget, allowed domains where possible, model name, and the reason native tools were insufficient.

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.

browser-use-agent is a skill published in the GitHub repository CodeInfinity1/Stram (10 stars, last pushed 22d ago), licensed MIT. It adds 32 tokens to every session and 696 once invoked, about $0.0002 per session on Opus 5. 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 2026-08-31.
