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

No annotations exist, and the description offers minimal behavioral disclosure. It implies a read-only status check via the response example, but does not confirm idempotency, side effects, or required permissions.

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 short but contains unnecessary formatting with markdown code fences. It could be expressed more succinctly, for example: 'Returns health status including version and timestamp.'

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 parameterless tool, the description is minimally adequate but lacks context. It does not explain the meaning of status values or when this health check differs from sibling tools like 'health_v12'. An example response is provided, but no further details.

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?

There are no parameters, so the schema is fully covered. The description adds a response example showing fields like status, version, and timestamp, which provides some context about what the tool returns, but it is not detailed enough to fully compensate for the lack of output schema.

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 is extremely vague, stating only 'Health'. It does not specify the verb or resource, but the response example suggests it checks service health. This is barely informative and does not distinguish from sibling tools like 'health_v12' or 'slate_health'.

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?

No usage guidelines are provided. The description does not indicate when to use this tool versus alternatives, nor does it give any context about prerequisites or conditions.

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