Get manga details

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is clear. The description adds context about the prerequisite step and the fact that it returns 'full details', which goes beyond the annotations without contradicting them.

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 two sentences: first states the main purpose, second provides crucial usage guidance. No fluff or repetition. Every sentence earns its place.

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 simple get-by-ID tool with one parameter and informative annotations, the description is adequate. It explains what the tool does and how to get the ID. The lack of output schema is mitigated by the mention of 'full details', though it could be more specific about the response structure.

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% with a description for the id parameter ('MyAnimeList numeric ID.'). The description merely restates that the id is a mal_id, adding minimal value. Baseline 3 is appropriate given high schema coverage.

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 the verb 'Get' and resource 'full details for one manga', and explicitly ties it to the parameter mal_id. It distinguishes from sibling tools like search_manga (which finds IDs) and get_top_manga (which lists popular manga).

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?

The description includes explicit guidance to 'Obtain the mal_id from search_manga first', telling the agent when to use this tool and what prerequisite step is needed. It implies this tool is for single manga lookup after search, which differentiates it from listing or aggregate tools.

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