create_importlist

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

Annotations already indicate readOnlyHint=false and destructiveHint=false, and the description correctly implies a mutation (create) without contradicting them. The description adds the useful directive to read the matching GET or /schema endpoint first, which hints at how to construct the body, but it does not disclose other behavioral aspects like idempotency semantics (though idempotentHint=true is annotated), required permissions, or the shape of the response.

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 and front-loaded with the purpose, which is good for scannability. However, it is too sparse: it lists arguments but omits any example or clarification that would help an agent. The structure is acceptable but could be improved by elaborating on the body requirements inline instead of only pointing to another endpoint.

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 complexity of an open 'body' object, an agent needs to know which fields to include. The description outsources this to the GET or /schema endpoint, which is a valid workaround but not self-contained. It does not explain the output schema, the behavior of force_save, or how this creation relates to other import-list operations. The presence of many siblings and an output schema (which is not described) further reduces completeness.

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 description provides minimal parameter meaning: 'body' is described as 'Request payload' (tautological) with a pointer to the GET/schema endpoint, and 'force_save' is only labeled as a 'Query parameter' without explaining its purpose. Since schema coverage is 0% and the body is an open object (additionalProperties: true), the description fails to compensate by explaining expected fields or the effect of force_save. This leaves the agent under-informed.

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 states the verb 'Create' and the resource 'ImportList' clearly, which is specific enough to distinguish it from most other create_* tools. It also provides the exact endpoint (POST /api/v3/importlist), adding precision. However, it does not differentiate from closely related siblings like create_importlist_movie or create_importlist_action_by_name, which might cause confusion about which exact operation to invoke.

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?

There is no guidance on when to use this tool versus the many sibling tools. The description does not mention any prerequisites, alternatives, or exclusions. An agent would have to infer from the name that it creates an import list, but it is not told when to prefer this over related create operations or how to handle bulk operations.

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