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 | $0.01566 | $0.01566 |
| Opus 5.5 | $0.00626 | $0.00626 |
| Sonnet 5.5 | $0.00313 | $0.00313 |
| Haiku 4.5 | $0.00157 | $0.00157 |
Grade C, and why
river-review AGENTS.md scanned grade C with 2 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 11d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
- Do not use destructive commands. The ban covers any command **you** run that rewrites already-pushed branch history (`git push --force` / `-f`, `git push --force-with-lease`) or discards work (`rm -rf`, `git reset --ha Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Do not make direct network calls (curl, wget, fetch) from scripts or code. Allowed CLI tools like `gh` are exempt. How it starts

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.

river-review AGENTS.md is an instructions file published in the GitHub repository s977043/river-review (7 stars, last pushed yesterday), licensed MIT. It adds 1,566 tokens to every session, about $0.0063 per session on Opus 5.5. A static security scan graded it C with 2 findings (recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
