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 | $0.00602 | $0.00602 |
| Opus 5.5 | $0.00241 | $0.00241 |
| Sonnet 5.5 | $0.00120 | $0.00120 |
| Haiku 4.5 | $0.00060 | $0.00060 |
Grade A, and why
stoa 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.
How it starts
The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md — STOA Platform
This repo uses CLAUDE.md as the canonical AI agent contract. AGENTS.md exists
as the cross-agent entry point for any AI coding assistant (Claude Code, Codex,
Cursor, Aider, etc.).
Contract
AI agents working in this repository must:
- Read
CLAUDE.mdat the repo root for project rules, architecture, runtime versions, workflow, and GO/NOGO gates. It is the single source of truth — this file does not duplicate its content to avoid drift. - Read the component-scoped
CLAUDE.mdinside the directory you are editing (e.g.stoa-gateway/CLAUDE.md,control-plane-api/CLAUDE.md,control-plane-ui/CLAUDE.md) when touching that service. - Load
.claude/docs/<topic>.mdon demand when a rule inCLAUDE.mdreferences it. These docs are protocols, examples, and gotcha tables — never auto-loaded, only pulled in when the topic is in scope. - Follow the same rules regardless of the tool brand. The
.claude/storage path is a naming convention, not a tool lock-in; any AI agent is expected to honor the rules defined there.
Language
Write in English by default: pull request titles and descriptions, review comments, commit messages, code comments, docs and any public communication. See the Language section of CONTRIBUTING.md. Conversations with the maintainer outside the repository may use another language; what is committed or published stays in English.

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.
