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

Annotations already declare readOnly, idempotent, openWorld and non-destructive, so the safety profile is covered elsewhere. The description adds nothing beyond that — no note on what the endpoint actually returns, whether results are cached, or what openWorld access to servers implies. The only added statement is that it takes no input, which the schema already shows.

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?

Roughly half the text is boilerplate: the "explicit tool with a fixed endpoint; not a generic endpoint caller" sentence and the search-terms tail add no information. The substantive content could be one 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?

With an output schema present and no parameters, the definition is technically callable, but it leaves the domain meaning of "no API servers" unexplained and provides no hint about result size or shape for an openWorld read.

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?

Zero parameters, so the baseline is 4; the description correctly states "No explicit input parameters required," which is consistent with the empty schema. Nothing further is needed.

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?

It names a specific operation (GET api/Dashboard/GetNoApiServers) but only restates the endpoint path; it never explains what a "no API server" actually is or what the dashboard returns. An agent can match it by name but cannot tell what it does in domain terms, nor distinguish it from hgr_get_noapi_servers or hgr_update_noapi_servers.

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 "Use when" line is circular — use it when a client needs to run this operation — giving no real trigger condition. There is no mention of when to prefer hgr_get_noapi_servers (the near-identical sibling) or any exclusion.

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