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

No annotations are provided, so the description must fully disclose behavior. It only mentions a return value ('Returns a TrackingLink') and a prerequisite (check programmeId via list_programmes). It does not disclose authentication needs, potential errors, side effects, or rate limits. For a tool with no annotation safety net, this is a significant 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?

The description is three sentences with clear functions: action, when-to-use, and follow-up guidance. Every sentence adds value, and the information is front-loaded. No redundant or filler content.

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 two-parameter tool, the description covers the main purpose and gives a useful pairing instruction. However, with no output schema and no annotations, it leaves out important context such as what a TrackingLink contains, authentication prerequisites, and failure modes. It is adequate but incomplete.

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 descriptions are absent (0% coverage), so the description must compensate. It offers minimal semantics: 'programme and destination URL' and that programmeId should be confirmed via list_programmes. However, it does not explain acceptable URL formats, constraints, or validation behavior for either parameter, leaving substantial ambiguity.

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 tool's action ('Generate a tracking link on Amazon Creators'), its key inputs ('programme and destination URL'), and its purpose (sharing an affiliate link to a product/page). This distinguishes it from the many sibling generate_tracking_link tools for other networks by naming the network explicitly.

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 guidance on when to use it ('when the user wants to share an affiliate link to a specific product or page on a merchant they have joined') and instructs practitioners to pair with list_programmes to confirm programmeId beforehand. It lacks explicit when-not-to-use or alternative network guidance, but the use case is clearly scoped.

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