AI & Agents

Three cryptographic primitives for autonomous agents: precision decisioning, provenance attestation, and intent binding. Every decision is HMAC-signed. Every action is hash-chained. Fail-closed.

Skills
Precision Decisioning

Verify a proposed action against policy bounds. Returns a cryptographically signed ALLOW, CLAMP, or DENY decision with a release token any downstream service can independently verify. Fail-closed: any doubt results in DENY.

Examples:
Verify I am authorized to execute this action
Get a signed release token so the target service trusts me
Check my action is within policy before I act
Provenance Attestation

Record a completed action in a hash-chained, append-only evidence ledger. Each record links to the previous via hash — tamper with any record and the chain breaks detectably.

Examples:
Record that I executed this action within authorized bounds
Add this action to my verifiable trust history
Build my provenance chain so other agents trust me
Intent Binding

Cryptographically bind a declared intent to a specific command. Prove later that what happened is what was planned. The HMAC binding is independently verifiable.

Examples:
Bind my declared intent to the command I am sending
Prove my action matched my stated goal
