Part of Agentic Primitives — the open-source trust substrate for agentic applications: identity that can sign, authority checked at act time, evidence the owner carries. Developer kit · All packages
The layer between candidate found and authorized provider is working (spec 336): a probe carrying a minimized
projection of an intent, the provider's response (offer · decline · needs-clarification · referral ·
temporarily-unavailable · human-ux-required — business facts, never errors), a firm offer signed over RFC 8785
canonical bytes, an acceptance that pins the offer's digest and can broaden nothing, the mandate requirement the
work will need (RFC 9396 shape — a description, never authority), the execute command, and the receipt that binds
intent, offer, mandate, executing agent and outcome by digest.
Pure. No transport, no keys, no LLM. Two deterministic reducers (decide → events, evolve → state) for the engagement
and offer state machines; models may suggest facts, they never transition state. Signing goes through the caller's signer.
