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

With no annotations, the description must disclose side effects, auth requirements, or other behavioral traits. It only states that it returns a TrackingLink and suggests a precondition; it does not clarify whether the operation is a persistent write, requires specific permissions, or has rate limits. This leaves a significant transparency gap.

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 concise sentences with the action front-loaded. The first sentence states the purpose, and the second adds return type and a useful usage tip. No wasted words.

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?

The description covers the core purpose, when to use, a return hint, and a key precondition, which is decent for a simple 3-param tool. However, the unexplained 'brand' parameter and absence of any behavioral or safety context mean it falls short of being fully complete for reliable invocation.

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 must compensate. It clarifies 'programme' and 'destination URL', but the required 'brand' parameter is never mentioned or explained. This omission means an agent cannot confidently determine what value to supply for 'brand'.

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 uses a specific verb ('Generate'), names the resource ('tracking link on Webgains'), and explicitly notes the advertiser scope, distinguishing it from the publisher-side Webgains tool and other networks' link generators. The first sentence fully captures the tool's action and target.

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 provides a clear when-to-use scenario ('when the user wants to share an affiliate link to a specific product or page') and a valuable prerequisite ('pair with list_programmes to confirm the programmeId'). However, it does not mention when not to use it or point to alternative tools.

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