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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds one genuinely useful behavioral fact — that the per-category reports are a free *preview* and the full list lives behind the returned page/pricing links. It says nothing about what happens with an unknown slug or about limits on counts.

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 sentence, front-loaded with the payload's core value ('what users struggle with') before the enumeration. It is dense and slightly overstuffed with parenthetical category lists and link caveats, but nearly every clause carries information the agent needs because there is no output schema.

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 no output schema and annotations covering safety, the description must carry the return-shape burden and largely does: counts, problem areas, four report categories, source links, and page/pricing links. Only failure behavior for an unrecognized product slug is left unaddressed.

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% and the single `product` parameter already documents the accepted slug/name/domain format with an example (grafana). The description only says 'one product' and adds no further semantics, so the baseline 3 applies.

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 enumerates exactly what the tool returns for a single product: struggle counts, main problem areas, per-category preview reports (pain points, feature requests, workarounds, switching reasons) and links. That makes the resource and content unmistakable. It never explicitly contrasts itself with list_products or search_items, so it stops short of a 5.

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?

Usage is only implied: the tool is a per-product overview with free-preview categories plus links to the full list. There is no statement of when to reach for this versus list_products (enumerate products) or search_items (find specific items), and no prerequisites or exclusions are given.

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