Get a user's profile

get_user_profile

Read-only

Retrieve a user's AniList profile and account settings by exact username or ID. Includes name, bio, avatar, donator status, language/notification preferences, and list options without viewer restrictions.

Instructions

Get an AniList user's public profile: name, about text, avatar, donator status — plus their account settings (title/name-language preferences, notification toggles, list display options). Confirmed live these settings are NOT viewer-gated, so they're included for any user, not just the authenticated caller. Accepts an exact AniList username directly — no need to call search_user first unless you only have a partial/fuzzy name and need to look up the exact one. Need statistics too? Use get_full_user_info instead of also calling get_user_stats separately.

A4.7/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true. The description adds useful behavioral context beyond that: it notes that account settings are NOT viewer-gated and are included for any user, not just the authenticated caller. This is a non-obvious fact that affects expectations. It does not mention response format or potential errors, but with readOnly covered by annotations, this is sufficient.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with the primary purpose, then adds the viewer-gating clarification, and ends with routing to alternatives. Each sentence earns its place with no redundancy or fluff. The structure logically guides an agent from what it does to when to use it.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool is simple (one parameter), has an output schema, and read-only annotations, the description covers everything an agent needs: what data is returned, that no authentication is required, how to supply the parameter, and how to avoid unnecessary search_user calls. It is complete for safe and correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already documents the parameter as 'AniList user ID, or username' (100% coverage). The description adds operational nuance: it accepts an exact username directly and clarifies that search_user is only needed for partial/fuzzy names. This enriches the schema's static definition with usage semantics.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool retrieves an AniList user's public profile and enumerates specific data points (name, about, avatar, donator status, account settings). It explicitly distinguishes itself from get_full_user_info (statistics) and search_user (lookup), so an agent can differentiate it from siblings without inspecting other schemas.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides explicit guidance: states that an exact username can be passed directly and that search_user is only needed for partial/fuzzy names. Also tells the agent to use get_full_user_info instead of calling get_user_stats separately when statistics are needed. This is clear when-to-use and when-not-to-use guidance.

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