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

With no annotations, the description carries full burden. It explicitly states the return fields (reviewer name, rating, title, content), which is transparent. However, it omits details like ordering (chronological?), idempotency, or auth requirements, but for a read-only tool this is fairly thorough.

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 sentences: first fronts the purpose, second lists outputs. No filler words; every sentence earns its place. Exceptionally 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?

No output schema exists, but the description compensates with return field names. It could mention ordering (e.g., 'newest first') or pagination behavior, but for a simple list tool with one parameter, it is largely complete.

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 100% for the single parameter (limit), so baseline is 3. The description adds value by listing the return fields, which the schema omits. This indirectly clarifies the tool's output semantics beyond the parameter.

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 verb 'Get' and the resource 'published reviews for this site (Wix Reviews)', making the purpose unambiguous. No sibling tool appears to handle reviews, so differentiation is inherent.

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?

While the tool is unique among siblings (no other review tools), there is no explicit guidance on when to use it or context like 'Use to display customer feedback.' It meets minimum clarity but misses proactive usage context.

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