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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive/openWorld=false, so the safety profile is covered. The description adds the cross-space scope but says nothing about ordering ('recent' is undefined), the default of 3 results, or whether results are paginated.

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?

A single ten-word sentence with zero redundancy, and the scope qualifier is placed where it matters, immediately after the resource.

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 simple, fully optional, read-only list tool with rich annotations, complete schema coverage, and no output schema, this is nearly sufficient. The remaining gap is that 'recent' has no defined window or sort order, which an agent would have to guess.

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 100%, so both optional parameters (limit with default 3, only_available with default false) are already fully documented in structured data. The description adds no format or interpretation details beyond the schema, so the baseline 3 applies.

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?

Clear specific verb (List) plus resource (recent reviews) and an explicit scope ('across all parking spaces'), which distinguishes it from the per-space sibling get_parking_reviews. It stops short of naming that sibling, so the differentiation must be inferred from the scope phrase.

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?

Usage is implied: the phrase 'across all parking spaces' suggests this is the cross-space feed as opposed to per-space review retrieval, but neither get_parking_reviews nor any other sibling is named, and there is no explicit when/when-not guidance.

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