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 | $0.02214 | $0.02214 |
| Opus 5.5 | $0.00886 | $0.00886 |
| Sonnet 5.5 | $0.00443 | $0.00443 |
| Haiku 4.5 | $0.00221 | $0.00221 |
Grade A, and why
OmoiOS 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md — AI Coding Agent Guide for OmoiOS
This document helps AI coding agents (Claude Code, Cursor, Copilot Workspace, Windsurf, etc.) understand and contribute to OmoiOS efficiently.
What is OmoiOS?
OmoiOS is a spec-driven, multi-agent orchestration system. Users describe a feature, OmoiOS plans it (requirements → design → tasks), executes it with autonomous AI agents in isolated sandboxes, and creates a PR. The core promise: "Start a feature before bed. Wake up to a PR."
Production: Frontend at https://omoios.dev, API at https://api.omoios.dev

| Document | Purpose | When to read |
|---|---|---|
| ARCHITECTURE.md | System design, service map, data flow | Before any backend work |
| UI.md | Frontend routes, components, state, design system | Before any frontend work |
| backend/CLAUDE.md | Backend conventions, patterns, anti-patterns | Before writing Python |
| CLAUDE.md | Monorepo structure, dev commands, ports | Always |
| CONTRIBUTING.md | Branch conventions, PR process, testing | Before submitting changes |
| docs/rules/ | Per-mistake rules — tripwires we've already hit (SQLAlchemy session handling, reserved column names, feature flag gotchas) | Before editing dependencies, route handlers, or models |

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.
- 1mo ago First seen · 171 lines · 2,214 tokens per session scan A 38fb1a751b3c
OmoiOS AGENTS.md is an instructions file published in the GitHub repository kivo360/OmoiOS (81 stars, last pushed 14d ago), licensed Apache-2.0. It adds 2,214 tokens to every session, about $0.0089 per session on Opus 5.5. 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.
