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

Annotations already declare readOnlyHint=true, so the read-only nature is covered. The description adds meaningful behavioral context beyond annotations: it discloses that the response contains recipient information and instructs not to disclose it publicly — a privacy caveat that is not present in the structured data. It also notes the links are scoped to the account, which is useful. This exceeds the annotation baseline.

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 contains no filler, but it is structurally awkward: the first sentence is a fragment ('Named links of the catalogue owned by the account') rather than a complete declaration. It does front-load the resource but not the action. The privacy note is useful but could be integrated more clearly.

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?

Given no output schema, the description should clarify what the tool returns. It does mention 'named links' and 'recipients', which hints at the response, but it omits pagination behavior (limit/offset), any mention of required parameters, or details about the link structure. For a simple listing tool this is adequate but not fully complete.

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%, and the description provides no information about any parameter. It does not mention catalogue_id, limit, or offset, nor their meanings or constraints. With zero schema documentation, the description compounds the gap and leaves the agent to infer parameter semantics from names and types alone.

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 is a noun phrase — "Named links of the catalogue owned by the account" — it does not state an action like 'list' or 'retrieve'. It relies entirely on the tool name and title to convey the operation. It is not a tautology, but it is vague and does not tell the agent what the tool does.

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?

No guidance on when to use this tool versus alternatives. There is no mention of when to prefer listing over creating or updating tracking links, nor any contextual cue such as 'use this to fetch existing links'. The description is silent on usage scenarios.

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