Get producers/studios

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

Annotations already declare readOnlyHint and openWorldHint, so the description adds little beyond stating the tool returns 'Jikan IDs and counts'. No contradictions, but minimal additional behavioral insight.

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 concise sentences with no wasted words. Purpose is front-loaded, and the key usage hint is provided immediately.

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 full schema descriptions, output schema presence, and annotations, the description is sufficient. It explains the tool's core functionality and search capability, missing only explicit mention of pagination or sorting.

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?

All 5 parameters have schema descriptions (100% coverage). The description only reinforces the `q` parameter's purpose. Baseline 3 is appropriate as the description adds marginal value over the schema.

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?

Description clearly states 'List or search anime producers and studios with their Jikan IDs and counts', specifying the verb and resource. It distinguishes itself from sibling tools like 'get_anime_genres' or 'get_top_anime' by focusing on producers/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?

Provides guidance to 'Use `q` to search by name', indicating when to use search vs list. However, it does not explicitly state when not to use this tool or mention alternatives, though the context makes it clear that this is the dedicated tool for producers/studios.

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