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 | $0.00241 | $0.00241 |
| Opus 5.5 | $0.00096 | $0.00096 |
| Sonnet 5.5 | $0.00048 | $0.00048 |
| Haiku 4.5 | $0.00024 | $0.00024 |
Grade A, and why
skills AGENTS.md scanned grade A with 0 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 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Repository Instructions
Writing Standard
Use ASD-STE100 Simplified Technical English for all technical prose in this repository.
This rule applies to these files and text fields:
SKILL.mdfiles- references and examples
- evaluation prompts and expected behaviors
agents/openai.yamlinterface text- the repository README
- code comments, docstrings, and user-facing diagnostic text
Use these writing rules:
- Use short, direct sentences.
- Use active voice.
- Put one instruction in each sentence.
- Use one term for one concept.
- Use the same term in all files that describe that concept.
- Do not use contractions.
- Do not use idioms, metaphors, or promotional language.
- Do not use
shouldfor a requirement or recommendation. Usemustfor a requirement. Use an imperative verb for an instruction or recommendation. - Keep exact technical names, identifiers, commands, paths, and quoted user text when accuracy requires them.
- Preserve a user prompt in an evaluation when its natural wording is part of the test.
Review this style during normal editing and review. Do not add automated language checks unless a repository owner requests them.
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.
