affiliate_rewardful_generate_tracking_link

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

No annotations are provided, so the description carries the burden. It adds value by stating 'Returns a TrackingLink' and advising to confirm programmeId via list_programmes. However, it does not disclose whether the operation has side effects (e.g., creates a record on Rewardful), requires authentication, or handles errors. The return type is named but not detailed, which is a moderate gap given no output schema.

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 three tight sentences, each providing distinct value: action, usage scenario, and return/prerequisite. It is front-loaded with the core purpose and wastes no 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?

For a tool with three required parameters, no annotations, and no output schema, the description covers the main purpose, a usage context, the return type, and a prerequisite. However, the brand parameter is left undefined, and the TrackingLink return type is not detailed. Overall, it is sufficiently complete for a simple link generation tool, with only minor gaps.

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?

The input schema has zero descriptions, so the description must compensate. It mentions 'programme' (programmeId) and 'destination URL' (destinationUrl), but the 'brand' parameter is completely unexplained. Since all three parameters are required and the schema provides no meanings, this omission leaves the agent guessing about a required input. The description also gives no format or validation hints for the mentioned parameters.

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 states the action ('Generate a tracking link'), the resource ('on Rewardful'), and the key inputs ('programme and destination URL'). It also mentions the return type, which helps distinguish it from other network-specific tools. The description differentiates from siblings by specifying 'on Rewardful'.

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 gives explicit usage context: 'Use this when the user wants to share an affiliate link to a specific product or page on a merchant they have joined.' It also provides a prerequisite by suggesting pairing with list_programmes to confirm the programmeId. However, it does not explicitly name alternatives or when not to use this tool, but the 'on Rewardful' phrasing implicitly distinguishes it from sibling network tools.

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