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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so safety is fully covered by structured data. The description adds nothing beyond that - no aggregation semantics, no scoping (workspace/portfolio?), no pagination or caching behavior.

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 the operation ID is already in the tool name. The only non-redundant content is the describe_operation pointer, which is buried at the end.

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 and no explanation of the returned statistic shape, plus undocumented query parameters, an agent cannot predict what this call returns or how to filter it. For a stats/aggregation endpoint, that is a material gap.

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?

Two parameters exist with 0% schema description coverage: an untyped 'query' object with free-form additionalProperties and an empty 'params' object. The description gives no hint about what query keys are accepted or what filters the stats endpoint supports, so it fails to compensate for the coverage gap.

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 a verbatim restatement of the endpoint path already given in the title, repeated twice. It conveys that this is a GET for notices statistics, but says nothing about what statistics (counts, by status, by date range) or how it differs from the sibling get_notices_eb8326fe048fba69ff1fd44e.

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 only actionable cue is 'describe_operation provides native request schemas', which points at a sibling tool but does not say when to prefer this tool over get_notices or the other stats endpoints. No conditions, no exclusions, no alternatives for the actual task.

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