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 | $0.04554 | $0.04554 |
| Opus 5.5 | $0.01822 | $0.01822 |
| Sonnet 5.5 | $0.00911 | $0.00911 |
| Haiku 4.5 | $0.00455 | $0.00455 |
Grade A, and why
synadia-agents CLAUDE.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 13d 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 — 329 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file orients Claude Code when working anywhere in this repo. For
language-specific deep dives, defer to the package-level CLAUDE.md (e.g.
client-sdk/python/CLAUDE.md) and to per-package READMEs.
What this repo is
The home for everything around the Synadia Agent Protocol for NATS — language
SDKs that callers use, agent plugins that host the protocol, and example
apps that exercise both. The root README.md covers the user-facing
view: layout, subject namespace, wire shape, quickstart. Read it before
making changes that touch user-visible surface.
The protocol spec is not vendored here. Canonical source:
synadia-ai/synadia-agent-sdk-docs
— always link to the GitHub URL when reasoning about wire shape. Local
docs/protocol-mapping.md files inside each SDK translate spec → impl;
they are not the spec itself.
Reference agents — canonical implementations
Every SDK in this repo ships a spec-compliant reference agent that
implements the full §12 agent-checklist (service registration, prompt
endpoint, status endpoint, heartbeats on agents.hb.*.*.*, terminator
semantics). When reasoning about wire shape, expected on-the-wire
behaviour, or testing a new SDK / agent, read these first — they are
the authoritative on-the-wire counterpart to the spec doc.
- TypeScript:
agent-sdk/typescript/src/testing/reference-agent.ts— theReferenceAgentclass, importable from third-party packages via@synadia-ai/agent-service/testing(post-SDK-split — pre-split it lived under@synadia-ai/agents/testing). Runnable script:client-sdk/typescript/examples/_run-reference-agent.ts. - Python:
agent-sdk/python/examples/_reference_agent.py— a runnable echo agent with conversation memory, used as the test harness for the numbered demos and as a wire-compat counterparty. (Moved with the host-side split intosynadia-ai-agent-service; pre- split it lived underclient-sdk/python/examples/.)
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.

synadia-agents CLAUDE.md is an instructions file published in the GitHub repository synadia-ai/synadia-agents (86 stars, last pushed today), licensed Apache-2.0. It adds 4,554 tokens to every session, about $0.0182 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.
