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

Annotations already declare readOnly=true, idempotent=true, destructive=false, and closed-world, so the safety profile is covered. The description adds only the operation ID and a pointer to describe_operation, revealing nothing about filtering behavior, pagination, or what the free-form query object accepts.

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?

Very short, but the endpoint string is duplicated verbatim, which is pure waste. What remains (operation ID, describe_operation pointer) is front-loaded but thin.

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, 0% parameter coverage, and nested free-form objects, the description should carry substantial weight; instead it delegates nearly everything to describe_operation. An agent cannot tell what the tool returns, how results are shaped, or how to filter.

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 opaque: 'query' is a free-form additionalProperties object and 'params' is an empty object. The description does not compensate at all beyond deferring to describe_operation, leaving the agent unable to construct a query without another call.

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 just restates the endpoint 'GET /api/review/entries' twice. It does convey the resource (review entries) fetched via GET, but gives no information about what a review entry is or how it differs from the many other get_* siblings.

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 guidance is a pointer that 'describe_operation provides native request schemas,' which is a next-step hint rather than a statement of when to use this tool versus alternatives like get_review_runs_by_id_* or get_review_readiness_*.

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