create_importlist_movie

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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false. The description does not contradict these and adds the procedural hint to read GET/schema endpoints first, but it does not disclose additional behavioral traits such as side effects, prerequisites, or error behavior.

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 compact and front-loaded: it states the purpose in one sentence, gives the endpoint, and explains how to handle the body parameter. There is no filler or redundant information.

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 that the body is an open object and an output schema exists, directing the agent to read GET/schema endpoints is a reasonable way to handle dynamic fields. The annotations cover safety and idempotency. However, it could be more complete by naming the specific matching GET sibling or clarifying the semantics of an importlist movie.

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 only parameter, body, is an open object with additionalProperties=true and 0% schema description coverage. The description adds value by labeling it as a request payload and directing the agent to the matching GET or /schema endpoint to discover expected fields, but it does not provide concrete field semantics or shape details.

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 and resource explicitly: 'Create ImportListMovies.' and gives the endpoint POST /api/v3/importlist/movie. This makes the tool distinguishable from create_importlist and list_importlist_movie, though it does not explain what an ImportListMovie is.

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 provides no guidance on when to use this tool versus siblings or when not to use it. The instruction to read the matching GET or /schema endpoint is about constructing the request body, not about selecting this tool over alternatives.

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