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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false and destructiveHint=false, so the safety profile is fully covered. The description adds essentially nothing beyond a redirect to describe_operation — no pagination behavior, filtering semantics, or response shape.

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 the first sentence is duplicated verbatim and contributes zero information. Brevity here comes from under-specification rather than efficiency.

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 list endpoint with an opaque two-parameter schema, no output schema, and no annotations gap to lean on, the description omits everything an agent needs: what entities are, whether results are paginated, how to filter, and what a response looks like.

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 the schema itself is almost opaque: 'query' is a free-form object with no defined properties and 'params' is an empty object. The description supplies no meaning for either parameter, leaving the agent with no way to know what to pass.

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 restates the HTTP method and path already present in the name and title ('GET /api/entities' appears twice) without saying what an entity is, what is returned, or how it differs from get_entities_by_id. It is effectively a tautology of the tool name.

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 guidance on when to call this versus siblings such as get_entities_by_id or the many other collection GETs. The only actionable pointer is that describe_operation supplies native request schemas, which hints at a prerequisite but does not describe usage conditions or exclusions.

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