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 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 6d 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.

When to Use

  • Automate web interactions (fill forms, click buttons, navigate pages)
  • Perform deep research across multiple web sources
  • Extract structured data from web pages
  • Learn and replay browser workflows as reusable skills
  • Monitor and manage long-running browser automation tasks

Core Tools

run_browser_agent

Execute a browser automation task using AI. Supports skill-based execution, learning mode, and background task execution.

Parameters:

  • task (string, required) - Natural language description of what to do in the browser
  • max_steps (integer, optional) - Maximum number of agent steps (default: from settings)
  • skill_name (string, optional) - Name of a learned skill to use for hints
  • skill_params (string or dict, optional) - Parameters for the skill (JSON string or dict)
  • learn (boolean, optional) - Enable learning mode to discover and extract APIs
  • save_skill_as (string, optional) - Name to save learned skill (requires learn=True)

Returns: Result of the browser automation task. In learning mode, includes skill extraction status.

Examples:

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.
