Single tool with adequate schema but weak descriptions and no error guidance. verify_agent has a clear name and proper input schema (target: string), but the description (95 chars) lacks WHEN to use it, prerequisites, or what the return fields mean. No parameter description for 'target' beyond the tool description. Output schema is undocumented, LLMs cannot plan downstream calls without knowing the structure of response_obj fields (agent_id, self_verified, attestation_level, etc.). No error handling guidance; exceptions are caught silently and degrade gracefully, but the LLM receives no actionable recovery hints. Naming is good (verb_noun pattern), but overall definition quality is below production baseline.

• Add a detailed tool description (150-250 chars) explaining: 'Verify a Creduent agent's identity and attestation status by querying the Creduent Registry. Use this to validate agent credentials before trusting their capabilities. Accepts agent:// URIs or domain names. Returns verification status, public key, and attestation level.'
• Document the 'target' parameter: 'The agent identifier as an agent:// URI (e.g., agent://idevsec/steward) or domain (e.g., creduent.idevsec.com). Required format: valid URI or FQDN.'
• Document the output schema with field descriptions: agent_id (string, the resolved agent identifier), self_verified (boolean, whether the agent's self-signature is valid), creduent_attested (boolean, whether the registry attests the agent), attestation_level (enum: unregistered|verified|...), public_key (string, agent's Ed25519 public key), endpoint (string, agent's service endpoint), capabilities (array of strings), checked_at (ISO 8601 timestamp).
• Add error handling guidance: return structured errors like {error: 'registry_offline', message: 'Creduent Registry unreachable. Retry in 30s or verify agent offline using self-signature only.', retryable: true} instead of silently degrading.
• Migrate from STDIO to HTTP+SSE or Streamable HTTP transport to enable remote client access and hosted deployment.
