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

Annotations already convey the read-only, idempotent, non-destructive profile, so the description gets no credit for those. 'Explicit freshness semantics' promises added behavioral detail but never explains what freshness means or how it is represented, leaving the tool's actual behavior largely undisclosed.

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 a single active sentence with the purpose front-loaded, which is efficient. But the key new idea, 'explicit freshness semantics,' is vague fluff until its actual semantics are specified, so the concision costs real content.

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?

There is no output schema and no mention of what the return payload contains, how freshness is reported, or how key status and identity status relate. For a tool named 'get_agent_identity_status,' the description still leaves the agent guessing at the outcome.

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?

The single required parameter, agent_id, has a strict pattern but no schema description, and coverage is 0%. The description mentions 'Agent ID' but does not clarify whether the parameter is the current agent, a target agent, or how 'current' relates to it, so the parameter's meaning is underdetermined.

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 states a specific action ('Resolve') and resource ('current Agent ID and key status'), so the tool's general job is visible. However, it does not differentiate it from sibling tools like get_agent_id_bootstrap or get_agent_identity_jwks, and 'freshness' is named but never defined.

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?

There is no guidance on when to use this tool versus alternatives such as verify_agent_signature or get_agent_public_profile. The description provides no conditions, exclusions, or hints about the situation where this particular identity-status lookup is the right tool.

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