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 | $0.03254 | $0.03254 |
| Opus 5.5 | $0.01302 | $0.01302 |
| Sonnet 5.5 | $0.00651 | $0.00651 |
| Haiku 4.5 | $0.00325 | $0.00325 |
Grade A, and why
ls-apis 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 2mo 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.
Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.

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.
- 2mo ago First seen · 293 lines · 3,254 tokens per session scan A 14ba9348e780
ls-apis AGENTS.md is an instructions file published in the GitHub repository koalyptus/ls-apis (1 stars, last pushed today), licensed MIT. It adds 3,254 tokens to every session, about $0.0130 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 2026-08-31.
