get_review_trends

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

No annotations provided, so description carries full burden. It warns that this server is an introspection stub and the actual endpoint is hosted, which is useful. However, it does not explain what 'review topic trends' means or any aggregation behavior.

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 front-load purpose and scope, then clarify stub vs hosted. No wasted words.

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?

Despite 100% schema coverage, the description lacks explanation of output format, meaning of 'review topic trends', and why an agent would choose this. The stub notice is helpful but incomplete for a tool with 7 parameters and no output schema.

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% with detailed descriptions for all 7 parameters. The description adds minimal extra value beyond 'six-month review topic trends' which implies a time range, but parameters already allow custom dates.

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 starts with '[Catalog / read]' and 'Six-month review topic trends,' clearly indicating a read operation for review trends over a six-month period. It distinguishes from sibling tools like get_product_reviews or get_sales_and_traffic.

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 guidance on when to use this tool vs alternatives. The description only notes it's a hosted endpoint stub, but does not explain use cases or when to choose it over other review-related tools.

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