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 | $0.04962 | $0.04962 |
| Opus 5.5 | $0.01985 | $0.01985 |
| Sonnet 5.5 | $0.00992 | $0.00992 |
| Haiku 4.5 | $0.00496 | $0.00496 |
Grade A, and why
agents-reverse-engineer AGENTS.md scanned grade A 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 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.

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.

agents-reverse-engineer AGENTS.md is an instructions file published in the GitHub repository GeoloeG-IsT/agents-reverse-engineer (22 stars, last pushed 1mo ago), licensed MIT. It adds 4,962 tokens to every session, about $0.0198 per session on Opus 5.5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
