youfiliate_get_smart_link

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

Annotations already indicate read-only and idempotent behavior. The description reinforces this with 'Does NOT modify the link' and adds details about returned data (geo rules, deep link config, click stats) and common errors, providing behavioral context beyond annotations.

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 concise (three sentences plus error hint) and front-loads the core purpose. Every sentence adds value, with 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?

Given the tool's simplicity (one required param) and the existence of an output schema, the description adequately covers purpose, behavior, and common errors. It could briefly mention the response_format parameter, but overall it is sufficiently 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%, but the description does not explain the parameters (id UUID format, response_format enum). It only mentions 'by ID' without elaboration. The description should compensate for the missing schema descriptions but fails to do so.

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 retrieves full details of a single smart link by ID, listing specific configuration elements (geo rules, deep link config, click stats) and explicitly notes it does not modify. This distinguishes it from list and stats-only sibling tools.

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 includes a common error scenario and suggests using youfiliate_list_smart_links if the ID is not found, providing guidance on when not to use this tool. However, it doesn't explicitly contrast with youfiliate_get_smart_link_stats or other similar tools.

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