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 | $0.06549 | $0.06549 |
| Opus 5.5 | $0.02620 | $0.02620 |
| Sonnet 5.5 | $0.01310 | $0.01310 |
| Haiku 4.5 | $0.00655 | $0.00655 |
Grade B, and why
ibanforge CLAUDE.md scanned grade B with 1 finding 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 today.
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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

AGENTS.md, à côté, dit la même chose pour les autres agents (Codex le lit, pas ce fichier-ci) : règles dures, versions de Node par zone, travaux en cours, et les deux conventions internes (une seule feuille de route, un rapport HTML par chantier). Une règle qui change ici change là-bas, sinon deux agents travaillent sur deux lois.

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.

ibanforge CLAUDE.md is an instructions file published in the GitHub repository cammac-creator/ibanforge (3 stars, last pushed yesterday), licensed MIT. It adds 6,549 tokens to every session, about $0.0262 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
