Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00109 | $0.00109 |
| Opus 5 | $0.00055 | $0.00055 |
| Sonnet 5 | $0.00022 | $0.00022 |
| Haiku 4.5 | $0.00011 | $0.00011 |
Grade A, and why
agent-os 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 2d 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
AGENTS.md
Companion doc for Claude Code: CLAUDE.md. Both files describe this repo for different coding agents — keep them in sync.
Default Delivery Rule
- When a task is complete, commit your changes and push to the remote unless the user explicitly says not to.
Git Hygiene
- Do not commit unrelated user changes.
- If the worktree is dirty, stage only the files touched for the current task.
- Do not amend commits unless the user explicitly asks for it.
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.

agent-os AGENTS.md is an instructions file published in the GitHub repository kai-linux/agent-os (5 stars, last pushed 1mo ago), licensed MIT. It adds 109 tokens to every session, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings.
