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 | $0.00004 | $0.00460 |
| Opus 5.5 | $0.00002 | $0.00184 |
| Sonnet 5.5 | $0.00001 | $0.00092 |
| Haiku 4.5 | $0.00000 | $0.00046 |
Grade A, and why
security 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.
This is a copy
98% identical to security — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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.
- 1mo ago First seen · 90 lines · 4 tokens per session scan A 9e8bc8c6f30c
security is a command published in the GitHub repository Fmarzochi/EGC (67 stars, last pushed today), licensed Apache-2.0. It adds 4 tokens to every session and 460 once invoked, about $0.0000 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 98% identical to security, differing in 2 lines, and is treated as a copy.
