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 | $0.01551 | $0.01551 |
| Opus 5 | $0.00776 | $0.00776 |
| Sonnet 5 | $0.00310 | $0.00310 |
| Haiku 4.5 | $0.00155 | $0.00155 |
Grade A, and why
infinite-brain-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 8d 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.

The opening of the file, as written. The whole thing — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Infinite Brain OS, Working Repo (Codex)
This repo is the operating system for running a business with AI agents. You have full write autonomy here. Codex does the heavy lifting; this file orients it.
If the task touches architecture, routing, knowledge structure, sessions, swarms, or planning, orient from this file and the doctrine first.
Forced startup for every non-trivial chat
For every non-trivial session that reads or writes repo state, do this before substantive work:
- Read
knowledge/ai-architecture/canon/doctrine-card.md. It is the compressed operating projection of core-doctrine: the hard rules, the control spine, the entity types, and the drill-down pointers. - If the task touches a knowledge domain, read
_system/retrieval-routing-map.mdand load the namespaces it routes to, entering each through itsINDEX.md. - For architecture-touching, contract-touching, or canon-touching work,
knowledge/ai-architecture/canon/core-doctrine.mdand_system/README.mdare mandatory reads. - Start the session ledger unless the task is truly trivial and leaves no durable change.
A trivial task is a one-line factual lookup or a no-file explanation. Hard rule: if the task creates, edits, moves, or deletes any file, it is non-trivial.
Forced session discipline
Unless the task is truly trivial, every chat session uses the sessions/ layer: register
under sessions/active/, declare a transcript path under sessions/logs/, keep running
notes, write a closeout review under sessions/reviews/, then move the record to
sessions/closed/. The contract is _system/session-ledger-rules.md; the technique is
entities/skills/manage-ai-session.md.
If a chat operates inside a swarm sprint, dual-write: sessions/ for the conversation
trail, swarms/Sprints/... for execution artifacts and receipts.
Disposable test artifacts default to outputs/, never to knowledge surfaces.
The eleven entities
Everything you build is one of eleven typed entities:
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.

infinite-brain-os AGENTS.md is an instructions file published in the GitHub repository starmynd-org/infinite-brain-os (248 stars, last pushed 12d ago), licensed MIT. It adds 1,551 tokens to every session, about $0.0078 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
