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

The annotations already disclose that the tool is destructive, idempotent, and not read-only, and the description adds useful operational context beyond that: it requires a connected account and the catalog:write OAuth scope, notes account tier limits, and advises re-reading the listing if the link changes. It does not explicitly spell out that existing title and slug values are overwritten, but the verb 'Set' plus the destructive annotation makes the risk clear.

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 description is short and front-loaded: the first sentence states the core action, followed by a usage note, authorization requirement, and limit warning. Every sentence contributes relevant information without unnecessary wording.

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 mutation with an output schema and annotations, the description covers purpose, authorization, account-tier limits, and the link-change caveat. It still leaves a gap around how to obtain listingId and what happens when the listing is not linked to a cultivar, but the core behavioral context is otherwise present.

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 0%, so the description needs to compensate for the single listingId parameter but does not explain its format, source, or how to obtain it. The phrase 'one owned listing' does add the ownership constraint, but it leaves the parameter largely undocumented beyond what the schema property name already conveys.

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 states a specific verb and resource: setting one owned listing's title and URL slug to the name of its linked cultivar reference. This is clearly distinct from generic listing updates and from the link_listing_to_cultivar sibling, so an agent can distinguish the tool without opening the schema.

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?

The description implies when the tool is relevant by referring to a listing's linked cultivar reference and noting that the listing should be read again if the link changes. However, it does not explicitly name alternatives such as update_listing for manual edits or link_listing_to_cultivar for establishing the link, nor does it state when not to use this tool.

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