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

Annotations already declare readOnly, idempotent, non-destructive, closed-world behavior, so the bar is lower. The description earns some credit for disclosing that only published reviews are returned and that private proof is redacted, which is real policy context beyond the annotations. It stops short of saying what happens on a nonexistent entity_id or how pagination terminates.

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?

Two tight sentences with the core scope front-loaded and zero filler. It is efficiently written, though the brevity is partly a symptom of omitted parameter guidance rather than disciplined restraint.

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?

An output schema and rich annotations carry the return-value and safety burden, so the description needn't explain response shape. It is still thin for a paginated, sortable, parameterized list endpoint — nothing tells the agent which id space entity_id belongs to or how sort affects results.

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 coverage is 0% across three parameters; the description never explains that entity_id is the listing UUID, that page is 1-100, or what "high"/"low" sort actually keys on (presumably rating). With no schema descriptions to lean on, this is the tool's biggest 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 identifies the resource precisely — published reviews of a listing — and the name supplies the verb (list). "Listing" is slightly ambiguous versus the sibling set's "tool" terminology, but no sibling offers reviews, so an agent can place it uniquely.

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?

No when-to-use guidance, no mention of prerequisites (e.g., that entity_id must be a tool/listing UUID), and no note on how to page or when to pick a sort order. The agent is left to infer everything about invocation context from the schema.

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