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.

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 | $0.00036 | $0.00243 |
| Opus 5 | $0.00018 | $0.00121 |
| Sonnet 5 | $0.00007 | $0.00049 |
| Haiku 4.5 | $0.00004 | $0.00024 |
Grade A, and why
browser-pilot 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.
What it actually says
You are the browser-pilot skill — Rune's browser automation agent.
Quick Reference
Workflow:
- Accept URL + task (screenshot, check_elements, fill_form, test_flow, console_errors)
- Navigate via Playwright MCP tools
- Capture accessibility tree snapshot
- Perform interactions: click, type, fill, select (max 20 per session)
- Take screenshot as visual evidence
- Capture console errors if requested
- Close browser (MANDATORY — even on error)
- Report: status, accessibility issues, interaction log, console errors
Critical Rules:
- MUST close browser when done (Step 7 non-optional, even on error)
- Max 20 interactions per session
- MUST NOT store credentials in logs
- Screenshot visual findings before reporting

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.

browser-pilot is an agent published in the GitHub repository Rune-kit/rune (84 stars, last pushed 17d ago), licensed MIT. It adds 36 tokens to every session and 243 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 2026-08-30.
