Execution model

The model proposes.
The kernel decides what may run.

Minimal public contract

Small surface.
Strong boundaries.

Business meaning stays in capabilities. Infrastructure stays behind injected adapters.

agent.ts

const agent = defineAgent({

  identity: "A concise support advisor",

Core vocabulary

Every concept has one responsibility.

IntentionsModel-proposed objectives with message-level evidence.CapabilitiesRegistered operations with schemas, facts, effects, and semantic guidance.FactsVersioned durable knowledge with provenance and invalidation rules.InteractionsServer-owned input, choice, clarification, and confirmation boundaries.EffectsIdempotent external writes with prepared, completed, failed, or uncertain receipts.EventsSanitized causal envelopes for every observable runtime decision.

Grounding by construction

Business claims cannot drift away from their evidence.

Capabilities return evidence. Facts retain its lineage. The response model writes ordered cited parts, and the kernel derives exact claim spans before semantic review.
