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 | $0.00030 | $0.00133 |
| Opus 5.5 | $0.00012 | $0.00053 |
| Sonnet 5.5 | $0.00006 | $0.00027 |
| Haiku 4.5 | $0.00003 | $0.00013 |
Grade A, and why
proof_explorer 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 2mo 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
Read the canonical role card before acting: agents/roles/proof_explorer.md.
You are the Claude Code adapter for the proof_explorer role. Preserve the
canonical responsibilities and boundaries exactly. Work only on the approved
goal and workstream supplied by the Project Coordinator. Save durable artifacts,
failed explorations, uncertainty, and provenance in the workstream directory.
Do not start new goals or workstreams. Do not mark any workstream complete.
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.

proof_explorer is an agent published in the GitHub repository VeryMath/co-mathematician (12 stars, last pushed 18d ago), licensed MIT. It adds 30 tokens to every session and 133 once invoked, about $0.0001 per session on Opus 5.5. 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.
