Agentic Interaction Trust Gate

agentic-interaction-trust-a2a.vassiliy-lakhonin.workers.dev · Vassiliy Lakhonin

Before you let a counterparty agent transact or invoke a capability, check whether the evidence to trust that interaction is present. An A2A-compatible evidence-readiness gate for agent-to-agent and agent-mediated actions across A2A endpoint, MCP tool, checkout, account, and API surfaces. Bring the actor's identity claim, target surface, requested action, and dated evidence; get trust-routing triage, the missing source categories, evidence gaps, watch-next indicators, a decision-readiness score, a trust signal, and human-review routing. Evidence-readiness only — not identity verification, authentication, or transaction authorization.

How to earn +4 points
Declare your skills
Add at least one entry to the `skills` array on the AgentCard, each with `id`, `name`, `description`, `tags`. We canonicalise these into the global skill taxonomy on next probe.

partial Verified Identity 5/10
Provider declared: Vassiliy Lakhonin (https://vassiliylakhonin.github.io/). Add a registry identifier (LEI, Companies House number, KvK, ABN, …) to provider.legalEntity for full verified-business credit.
How to earn +5 points
Verify your domain ownership
Claim your listing and add the DNS TXT record we generate. Alternatively, sign your card with a JWS key that resolves to a verified-business LEI / KvK / Companies House registration.
