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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered structurally. The description adds zero behavioral context (no pagination, filtering, or result shape), so it contributes nothing beyond the annotations.

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?

It is short but wasteful: the same endpoint string is repeated verbatim, and the sentence that follows is metadata (operation ID) rather than purpose. Nothing meaningful is front-loaded because nothing meaningful is stated.

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 no output schema, no useful annotation gap-filling, and 0% parameter documentation, the description should explain at least what the endpoint returns and what the query envelope accepts. It provides none of that, only a routing hint to describe_operation.

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% and both parameters are untyped catch-all objects (query, params), so the description carries the full burden of explaining them — and it says nothing. No meaning is added for either parameter, leaving the agent to guess at query syntax.

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 only restates the endpoint path twice and the operation ID; it never says what the resource 'comments/users' represents or what the call returns. An agent learns nothing beyond the name itself and cannot distinguish it from siblings like get_comments_f4c37d690dc3849e975c2997 or get_comments_mentions.

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 when-to-use guidance, no conditions, and no named alternative among the many comment/user siblings. The only actionable hint, 'describe_operation provides native request schemas', is a pointer to another tool rather than usage direction.

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