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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states what information is reported but does not mention whether the operation is read-only, any authentication requirements, rate limits, or potential side effects. For a health check, one would expect it to be safe, but that is not stated. The description provides minimal behavioral context beyond the listed fields.

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 concise sentence that front-loads the primary purpose ('FREE service health') and lists the key attributes. It is efficient with no fluff. It could arguably be expanded slightly to include usage guidance, but as a standalone statement it is appropriately sized and structured.

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?

Given the tool has no parameters and no output schema, the description is expected to carry more weight. It lists what is covered (network, uptime, supported venues, exec status) but does not explain the format of the response, how to interpret 'exec status', or any caveats. While it is minimally complete for a simple health check, the lack of any mention of output structure or additional context leaves some gaps.

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 tool has zero parameters, and the schema is trivially complete (100% coverage). Since there are no parameters to explain, the description does not need to add parameter semantics. This is a baseline 4 for a parameterless tool, as there is nothing further the description could clarify.

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 the tool as a health status check for the service, listing specific aspects (network, uptime, supported venues, exec status). It is distinguishable from siblings like farm_baddebt or farm_summary, which imply different concerns, though it doesn't name an explicit verb like 'get' or 'check'. Overall, the purpose is clear and specific.

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 explicit guidance on when to use this tool versus alternatives. Given the large set of sibling tools (farm_*, each with distinct functions), the description does not explain scenarios where health is the appropriate query, nor does it mention any exclusions or prerequisites. The usage context is only implied by the tool's name and description.

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