get_movies_by_id_studios

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

The annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is established. The description adds no behavioral context beyond repeating 'Get' and the GET endpoint; it does not mention pagination, auth, or any other runtime behavior. There is no contradiction, but also no added transparency.

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 extremely compact: a one-line purpose, the endpoint, and a single parameter note. It front-loads the core meaning and contains no filler.

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 one-parameter read operation with output schema and strong annotations, this is nearly adequate. The remaining gap is that it gives no context about what a studio represents or any usage boundaries, though these are not critical for a basic GET.

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 schema only says the id is a string, and schema description coverage is 0%. The description compensates by stating that id is 'The id/slug of the resource', which adds the meaningful fact that slugs are accepted and ties the parameter to the movie resource.

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 a specific verb and resource: 'Get movie studios.' The endpoint 'GET /movies/{id}/studios' makes the target resource unambiguous, and the mention of 'movie' distinguishes it from the sibling get_shows_by_id_studios.

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?

Usage is implied by the resource name and endpoint: call this when you need the studios associated with a specific movie. However, there is no explicit statement about when to prefer this over alternatives, nor any mention of when not to use it.

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