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 | $0.09037 | $0.09037 |
| Opus 5.5 | $0.03615 | $0.03615 |
| Sonnet 5.5 | $0.01807 | $0.01807 |
| Haiku 4.5 | $0.00904 | $0.00904 |
Grade E, and why
cass_memory_system AGENTS.md scanned grade E with 3 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 8d 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.
<!-- bv-agent-instructions-v1 --> Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
1. **Absolutely forbidden commands:** `git reset --hard`, `git clean -fd`, `rm -rf`, or any command that can delete or overwrite code/data must never be run unless the user explicitly provides the exact command and state Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
For any web requests you must make with curl or otherwise, identify yourself honestly: use a User-Agent that names this project, e.g. "cass_memory_system-agent (+https://github.com/Dicklesworthstone/cass_memory_system)". The source is not reproduced here
A licence we could not identify
The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.
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.
