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 | $0.01180 | $0.01180 |
| Opus 5 | $0.00590 | $0.00590 |
| Sonnet 5 | $0.00236 | $0.00236 |
| Haiku 4.5 | $0.00118 | $0.00118 |
Grade A, and why
cardano-org 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 3d 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 — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md - AI Agent Onboarding for cardano.org
Use
yarnfor all dependency and script management, notnpm: the repo is pinned toyarn.lock, and PRs must not modify that file.
Welcome! This guide enables AI agents (and their operators) to contribute productively and safely to cardano.org. It covers philosophy, repo map, quickstart, quality gates, guardrails, and content rules.
Project Philosophy
- Collective Ownership: cardano.org is managed by a community, not a single entity. All contributions are welcome and valued.
- Incremental Evolution: Prefer small, reviewable, continuously shipped changes. Avoid large, disruptive changes unless discussed and agreed.
- Discussion First: For any non-trivial change, start with a discussion before implementation.
Essential Resources
- README.md: Project overview, setup, and contribution boundaries.
- CONTRIBUTING.md: Contribution guidelines and workflow.
- docs/get-involved/: Guides for all types of contributions (content, code, design, data, community).
- docs/get-involved/style-guide.md: Editorial style guide (spelling, capitalisation, brand-name conventions). Mandatory for all content and code comments.
- glossary/: Per-term definitions rendered at
/glossary/<slug>. Reference these for consistent terminology across docs and UI copy.

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.
