update_mymangalist

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

No annotations provided, and the description only says 'updates' without disclosing important behavioral traits such as authentication, idempotency, error handling (e.g., manga not in list), rate limits, or whether it's a partial or full update.

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 sentence followed by an Arg block that largely duplicates the schema. While structured, it is not maximally concise; the Arg block could be omitted or shortened since the schema already provides details.

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 11 parameters, no output schema, and no annotations, the description lacks essential context: no return value description, no error scenarios, no authentication requirements, and no behavioral details. It is incomplete for an update tool.

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%, so the schema itself documents parameters well. The description adds marginal value by listing possible status values and repeating schema info, but does not add new semantic context beyond what the schema provides.

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 it updates a manga's status in the user's MyAnimeList, but it implies only 'status' when the tool can update many fields like score, volumes, etc. However, the Args list compensates, and sibling tools like update_myanimelist differentiate by resource.

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 on when to use this tool vs alternatives, no prerequisites (e.g., authentication, manga must be in list), and no when-not-to-use conditions. The sibling tools are not mentioned or compared.

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