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 | $0.00103 | $0.00103 |
| Opus 5.5 | $0.00041 | $0.00041 |
| Sonnet 5.5 | $0.00021 | $0.00021 |
| Haiku 4.5 | $0.00010 | $0.00010 |
Grade B, and why
AgentSec AGENTS.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 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.
Recursive force deletemediumDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
- **Destructive Operations:** Always prompt for human approval before executing destructive actions (e.g. drop table, rm -rf, force push). Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
What it actually says
Agent Guidelines
Security & Tool Execution Guidelines
- Autonomous Shell: Direct shell execution without user confirmation is strictly prohibited.
- Data Protection: Never output or expose API keys, tokens, or private credentials in chat or commits.
- Filesystem Integrity: Restrict write operations to the active project workspace. Do not modify system root or external home paths.
- Destructive Operations: Always prompt for human approval before executing destructive actions (e.g. drop table, rm -rf, force push).
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.
