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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds some behavioral scope by describing the returned report categories and links, but because an output schema exists, this largely repeats structured return information and says nothing about data freshness, access requirements, or pagination.

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 definition is a single dense sentence that front-loads the product-struggle focus and enumerates the returned content efficiently. It is slightly convoluted with multiple nested lists, but it avoids unnecessary padding.

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?

For a simple one-parameter, read-only tool with full schema coverage and an output schema, the definition is adequate in describing what is returned. However, it omits usage guidance and any operational context, leaving the agent to infer when this tool is preferable to alternatives.

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 product parameter, and the schema explains that it accepts a slug, name, or domain with an example. The description adds no additional meaning about the parameter 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?

The description identifies a specific resource and scope: a summary for one product covering user struggles, counts, problem areas, and linked reports. It is clear what data the tool surfaces, although it is phrased as a list of outputs rather than an explicit verb and does not distinguish itself from siblings like list_products or search_items.

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?

There is no explicit guidance on when to use this tool, when not to use it, or which sibling to choose instead. The agent must infer usage from the description's content list alone.

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