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

Annotations already declare readOnly, openWorld, and non-destructive behavior. The description adds meaningful context beyond that: the access constraint of owned/shared agents, the presence of a nested trust score, the fact that a provisional score is null, and the limitation that it is not a safety certification.

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?

Two short sentences, front-loaded with the tool's action and scope. The second sentence adds useful limitations without repeating the schema or annotations. It is appropriately sized, though 'nested trust score' could be slightly clearer.

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?

An output schema exists, so return values need not be explained, and annotations cover the safety profile. Still, with many sibling tools and zero schema parameter documentation, the description leaves gaps about when to use this versus get_agent_status and how agent_id/api_key affect access.

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 0%, so the description would need to explain agent_id and api_key. It does not describe either parameter's meaning, format, or whether api_key is required for access. It only implies an ownership/sharing condition indirectly.

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 names a specific verb and resource: reading operational status and a nested trust score. It also clarifies that it is not an identity/safety certification, which sharpens scope. However, it does not distinguish itself from close siblings such as get_agent_status.

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?

It gives an access condition ('owned or explicitly shared') and a negative scope ('not identity/safety certification'), which implies some when-not-to-use guidance. But it does not name alternatives or explain when to choose this tool over get_agent_status or agent_health_checks.

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