Get producer/studio details

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds genuine payload context beyond that: what this returns over the list tool (about text, official site and social media links), which tells the agent why to pay the extra call. It does not mention behavior for invalid or unknown IDs.

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?

Two sentences, both load-bearing: the first states what is returned and how it differs from the list tool, the second states the id prerequisite. Nothing is padded or repeated from the title.

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?

With an output schema present, return values need no prose, and the description covers purpose, delta fields, and id provenance. The only gap for a lookup tool is error behavior on a nonexistent id, which is minor but absent.

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 coverage is 100% and the single id parameter is already documented. The description adds meaning the schema cannot: that the value is a MyAnimeList producer/studio id and where to source it (get_producers), which reduces wrong-id errors.

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 names a specific verb and resource ('Get full details for one anime producer/studio') and explicitly scopes it against the sibling list tool by noting it returns 'the fields get_producers already returns' plus extras. An agent can distinguish this detail endpoint from get_producers without opening either schema.

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?

It gives a clear precondition and call sequence: 'Obtain the mal_id from get_producers.' That routes the agent to the correct discovery tool first. It stops short of stating when-not to use it (e.g., for bulk listing), so it lands just under the explicit-alternatives bar.

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