SIGNET Specification v0.1 — Request for Comments

Today Concert publishes the initial SIGNET specification (v0.1) as a Request for Comments. This is an open invitation: we want the procurement, standards, and AI communities to read, challenge, and improve it.

What v0.1 covers

The specification defines three things in detail:

  1. The five-layer architecture — Experience, Agent, Intelligence, Core Services, and Integration layers, each with defined responsibilities and interfaces.
  2. The GUILD principles — the five properties that every conforming SIGNET network must exhibit.
  3. The harness primitives — prompt and policy, durable state, tool registry, memory and context, verification, sandboxing, and runtime.

How to contribute

The specification is published under a royalty-free licence following the W3C Patent Policy model. Implementing it never requires patent licence negotiations.

Comments on v0.1 are open through the Standards Committee. Reference implementations carry the most weight — in keeping with the principle that technical consensus is proven by working code. Get in touch to join the review.
