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-computer-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 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.

Use this skill when a task requires web navigation, browser UI testing, desktop GUI observation, or Windows app control.

Workflow

  1. Observe current state before acting.
  2. Prefer browser tools for web pages and OS/UI tools for native desktop apps.
  3. Use element ids from the most recent observation instead of stale coordinates when possible.
  4. Take one state-changing action at a time, then observe again.
  5. Keep high-risk GUI actions approval-gated.
  6. Use Codex or Playwright guidance as evidence when it is available, but choose tools through model reasoning and schemas.
  7. For local browser sessions, use stored session_id plus observed element_id values.
  8. For live browser sessions, use live_session_id and re-observe after clicks, typing, uploads, downloads, JavaScript, screenshots, or PDF saves.
  9. For Windows UI, use os_active_window and os_observe_ui before os_click_element, os_type_text, or os_send_keys.
  10. Stop on login, captcha, payment, identity verification, destructive confirmation, or unclear UI state.
