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 | $0.00267 | $0.00267 |
| Opus 5.5 | $0.00107 | $0.00107 |
| Sonnet 5.5 | $0.00053 | $0.00053 |
| Haiku 4.5 | $0.00027 | $0.00027 |
Grade A, and why
xbsl 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 9d 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.
This is a copy
89% identical to elemctl AGENTS.md — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Agent instructions
If a local CLAUDE.md is present, read it for additional repository conventions.
The documentation policy below applies to every checkout.
Documentation
Required skill: tooling-docs-writing. Before creating, editing or proofreading
documentation, load and apply this skill automatically, without waiting for the task
to name it. Use it together with humanizer when that skill is available.
This applies to both English and Russian documentation: website pages under docs/,
README and contributor guides, changelogs, reference pages, frontmatter and package
annotations, and user-facing CLI/MCP help and descriptions in source files. For
generated pages, edit the source and regenerate the output. Keep RU/EN editions
consistent and run the existing checks relevant to the changed documentation.
Resolve tooling-docs-writing from the runtime's installed skills. If it is not
listed, check ~/.codex/skills/tooling-docs-writing/SKILL.md and
~/.agents/skills/tooling-docs-writing/SKILL.md. If it cannot be found, report that
it is missing; do not silently skip it or claim that it was applied.
The skill is the source of the editorial rules; do not maintain a separate copy here.
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.
