Kevros Governance Agent

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.

What's Being Tested

Availability

HTTP health check to the service endpoint

Responded with HTTP 402 in 67ms

Conformance

A2A Agent Card validation + JSON-RPC probe

Agent Card schema valid, JSON-RPC response invalid, endpoint matches card

Performance

Skill-specific task probing

P95 latency: 1552ms, task completion: 0%

Improvement Tips

-Reduce response time (currently 1552ms, target <1000ms)
-Ensure endpoint returns valid JSON-RPC responses

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

Create a verifiable intent-action-outcome chain
