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

With no annotations, the description carries the burden and discloses important behavior: newest-first ordering, that the link itself is never shown again, and the owner/office access restriction. It still does not explicitly declare read-only status or pagination behavior, so it is strong but not fully comprehensive.

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 brief, front-loaded with the resource and ordering, and every sentence adds useful information about return fields, privacy, or access. There is no wasted text.

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 listing tool with an output schema, the description covers ordering, key returned fields, privacy behavior, and access restrictions. It is nearly complete, though it could mention pagination or explicit read-only behavior.

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 only implies that customer_id selects the customer. It does not add format or validation details beyond what the parameter name already suggests, leaving the single required parameter under-specified.

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 clearly identifies the resource (a customer's hub links) and the scope/order (newest first), and it enumerates the fields returned. An agent can distinguish it from hub_createLink and hub_revokeLink without inspecting schemas.

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?

It states an access restriction ('Owner or office only'), which is useful context, but it does not explicitly say when to use this tool versus alternatives like hub_createLink or hub_revokeLink. Usage is implied rather than stated.

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