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 real value beyond that by disclosing the exact return payload and a reproducibility guarantee — the order matches what the category page and rankings.json publish — though it says nothing about behavior for an invalid or unranked category.

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 tight sentences, front-loaded with the resource and immediately followed by the payload contents; nothing is padding. The repeated 'publish/published' wording is slightly redundant but minor.

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 only two parameters, no nested objects, no output schema and rich annotations, the description is nearly sufficient — it compensates for the missing output schema by listing the fields returned. The remaining gap is sibling disambiguation against get_ranking_for_country, which a mature definition would resolve.

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 category parameter's example ids and the limit's 1-50 range with default 10 are already fully documented in the schema. The description adds only the framing 'one category' and does not clarify ordering or what happens when limit exceeds the ranking length, so 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 names the resource ('the published order of one category') and enumerates the payload fields (rank, product id, name, ChainChoice Score, methodology version, dimension weights, assessment), so an agent knows exactly what it gets back. It stops short of differentiating itself from the sibling get_ranking_for_country, which an agent could easily confuse with a category-only ranking.

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 when-to-use or when-not-to-use guidance at all; the description only says what the tool returns. The most likely misuse case, calling this instead of get_ranking_for_country, is never addressed, and no prerequisites (e.g. resolving a category id first) are stated in prose.

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