get_anime_list

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

With no annotations, the description must disclose behavioral traits. It mentions pagination via limit/offset and lists parameters, but does not state that the tool is read-only, require authentication, or describe rate limits. The word 'fetches' implies a read operation, but this is not explicit.

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 concise, starting with a clear purpose sentence and then listing parameters in a structured Args block. Every sentence is informative, no redundancy, and the format is easy to parse.

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 no output schema, the description does not explain return values. However, it covers all input parameters thoroughly. The tool's role among 14 siblings is partially clarified by the word 'list', but additional context about return structure would improve 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 input schema has 0% description coverage, so the description fully compensates by explaining all 5 parameters: username (user identity), status (options listed), sort (options and default), limit (default and max), offset (default). This adds significant meaning beyond the schema's types and titles.

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 clearly states 'Fetches an anime list for a user from MyAnimeList', specifying the verb and resource. However, it does not differentiate from sibling tools like get_anime or get_anime_ranking, which could cause confusion about which tool to select for list retrieval.

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?

No guidance is provided on when to use this tool versus alternatives such as get_anime or get_seasonal_anime. The description lacks context for tool selection and does not mention prerequisites or exclusions.

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