get_review_by_id

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

No annotations are provided, so the description carries the full burden. 'Fetch' implies a read operation, but there is no disclosure of error behavior, authentication needs, or what distinguishes a 'segment' from a regular review. The description essentially restates the tool name without adding meaningful behavioral context.

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?

The description is a single, direct sentence that is front-loaded with the action and resource. No unnecessary words or repetition, making it highly concise.

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?

Given the simple signature and presence of an output schema, the description is minimally adequate. However, it does not distinguish this tool from closely named siblings like get_review or get_reviews_by_ids, leaving potential ambiguity about when to use this specific fetch-by-ID variant.

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?

The input schema covers the sole parameter (review_id) with a description ('Review segment ID'), providing 100% coverage. The tool description adds no additional meaning beyond this, so the baseline score of 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?

The description clearly states the action ('Fetch') and the specific resource ('a single review segment by its ID'), making it distinct from sibling tools like get_reviews_by_ids and get_review_by_event. The verb+resource structure is specific and unambiguous.

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 description implies usage when a review segment ID is available, but it does not explicitly state when to choose this tool over alternatives like get_review or get_review_by_event, nor does it offer exclusions. Guidance is purely implied by the tool's name and description.

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