Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full behavioral burden. It usefully discloses the returned proof contents and notes that the chain transaction is included only when enabled, but it omits authentication behavior, permission requirements, and what happens when no anchored proof exists.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact and front-loads the proof identity and contents. The dense enumeration of proof components is appropriate, though slightly long as a single sentence.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a two-parameter getter with no output schema or annotations, the description does well by naming the returned proof fields and pointing to a verification specification. It still lacks preconditions, auth context, and error behavior, but the core retrieval semantics are covered.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 50%, with only api_key documented structurally. The description implies agent_id through 'an agent's latest anchored identity record' but does not explain its required format, and it never mentions the api_key parameter or its auth role.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies a specific resource: the agent's latest anchored identity record and its proof bundle. It enumerates the proof components, so an agent understands what the tool retrieves. It does not explicitly differentiate itself from nearby siblings such as verify_agent_card or get_agent.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description says the proof can be verified with the spec, but it does not explain when to use this tool versus alternatives like verify_agent_card or get_agent. There are no explicit inclusion/exclusion conditions or prerequisites.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
