AgentNetworkProtocol (ANP) is an open-source protocol suite that defines how software agents identify each other, discover services, negotiate, exchange secure messages, and collaborate. It is intended for developers building networks of interacting intelligent agents. The catalogue entries are instructions for working with ANP.

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 | $0.01213 | $0.01213 |
| Opus 5.5 | $0.00485 | $0.00485 |
| Sonnet 5.5 | $0.00243 | $0.00243 |
| Haiku 4.5 | $0.00121 | $0.00121 |
Grade A, and why
AgentNetworkProtocol 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 14d 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 — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repository Guidelines
Shared rules
Engineering work follows AI Coding Rules. Behavior changes and verification follow the relevant Verification Policy sections; production behavior needs owning unit coverage and applicable System/product E2E review. If Harness is absent, use local docs/tests/CI and disclose missing acceptance evidence.

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.
