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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that results are paginated and that a cursor comes from a previous response, which is useful but largely mirrors what the cursor parameter already conveys; no further behavioral context (rate limits, auth) is added.

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 purpose is front-loaded in the first sentence, followed by parameter clarifications. It is compact, though the repetition of id and cursor details that already appear in the schema is slightly redundant.

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 the annotations cover the read-only/open-world profile. The description adequately covers what the tool returns (alternatives, tags, related discussions) and how to page through it, leaving little the agent still needs.

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 already documents all five parameters. The description restates the id and cursor semantics without adding format or edge-case guidance, which is the expected baseline when the schema does the heavy lifting.

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 gives a specific verb and resource: 'Returns paginated alternatives, tags, and related discussions for a Product Hunt product.' That is more informative than the bare name, though the differentiation from sibling tool producthunt_product is only handled by a routing sentence rather than by contrasting scope.

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?

It names an explicit alternative and the condition that selects it: 'Use producthunt_product to retrieve Product Hunt product details.' There is no explicit statement of when NOT to use this tool, but the routing to the detail tool gives clear context for selection.

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