get_anime_list

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

With no annotations provided, the description carries the full burden of behavioral disclosure. 'Fetch' implies a read-only operation, but there is no mention of authentication requirements, rate limits, pagination behavior, error handling, or what the response contains. The description is too sparse to convey meaningful behavioral context.

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 a single, clear sentence of eight words. Every word contributes meaning, and it is appropriately front-loaded with the core action and target. There is no unnecessary 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?

For a tool with 5 parameters, no output schema, and no annotations, the description is too minimal. It fails to convey pagination options, sorting behavior, status filtering, or return value expectations. The description is a bare minimum and leaves significant gaps for an agent to navigate correctly.

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 description does not mention any parameters. The input schema covers 60% of parameters (limit, offset, username have descriptions), but status and sort lack explanations beyond their enum values. Since the description adds no semantic context for these parameters, the overall parameter semantics are incomplete.

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 'Fetch an anime list for a MAL user' uses a specific verb ('Fetch') and resource ('anime list') with a clear scope ('for a MAL user'), which distinguishes it from sibling tools like get_anime_ranking or get_manga_list. It fully clarifies what the tool does.

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?

There is no guidance on when to use this tool versus alternatives. The description does not mention any exclusions, prerequisites, or context for choosing it over other list/ranking tools, leaving the agent to infer usage from the name alone.

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