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

Annotations declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds the aggregate-rollup nature of the results, which is useful context beyond annotations. However, it mentions nothing about the built-in suppression floor mentioned in the schema, result format, or pagination 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?

A single front-loaded sentence with zero waste. It states the tool's purpose and the key distinguishing characteristic (aggregate rollups) in one compact clause.

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?

With an output schema present, return values need not be explained, and annotations cover safety. The description is adequate but thin for a 9-parameter tool: it does not clarify that topic is an exact-slug filter, that group_by changes the aggregation granularity, or how the suppression floor behaves, leaving the agent to rely entirely on the 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 description coverage is 100%, so the schema documents all 9 parameters including the suppression-floor behavior of min_launches. Baseline 3 is appropriate; the description adds no parameter syntax or meaning beyond what the schema already provides.

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?

States a specific verb (Search) and resource (Product Hunt trends dataset) with a clarifying parenthetical that it is aggregate category-over-time launch rollups. This distinguishes it from sibling product-level tools (datasets_producthunt_products_search) and maker tools, though it does not name those siblings explicitly.

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 when NOT to use it, and no routing to alternatives like datasets_producthunt_products_search or datasets_producthunt_makers_search. The description tells you what the tool is but not when to choose it over siblings.

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