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 | $0.00159 | $0.00159 |
| Opus 5.5 | $0.00064 | $0.00064 |
| Sonnet 5.5 | $0.00032 | $0.00032 |
| Haiku 4.5 | $0.00016 | $0.00016 |
Grade A, and why
camofox-browser GEMINI.md 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 it actually says
GEMINI.md — CamoFox Quick Rules
Essential pattern: snapshot-first, ref-driven browser automation with explicit user scope.
Key Rules
- Start with tab open/create, then run snapshot before interacting.
- Use refs (
eN) for click/type/fill/press; selector usage is fallback only. - Re-run snapshot after navigation or major DOM mutation.
- Prefer structured output (
--format json) for automation pipelines. - Use encrypted auth vault injection; never print or persist plaintext secrets.
Context
- Base URL:
http://localhost:9377 - Core entities:
userId,tabId,sessionKey - Common loop: navigate -> snapshot -> act -> snapshot

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.
