Get my MAL profile

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

Annotations already declare readOnlyHint and openWorldHint, so safety is clear. The description adds that it returns anime statistics, but does not disclose specifics like response structure or potential empty states. The description provides marginal added value beyond annotations.

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?

A single sentence of 10 words, no redundancy, straight to the point. Every word 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 zero-parameter retrieval tool with no output schema, the description is adequate but vague on what exactly is returned (e.g., username, anime stats list). Could be more specific, but given simplicity, it's minimally acceptable.

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?

No parameters exist, so baseline is 4. The description provides no parameter details, but schema coverage is 100% (no params to describe). No additional meaning needed.

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 retrieves the authenticated user's MyAnimeList profile and anime statistics, with a specific verb ('Get') and resource ('MAL profile'). This distinguishes it from siblings like get_user_profile (which may be for other users) and get_my_anime_list (which is a list, not profile/stats).

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 implies usage for getting own profile and stats, but does not explicitly state when to use it versus alternatives, nor does it mention any prerequisites or exclusions. However, given the zero-parameter design, the context is clear enough.

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