get_my_bilibili_profile

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

No annotations are present, so the description carries the behavioral disclosure burden. It mentions 'requires login', which is useful, and the 'Get' verb implies a read-only operation. However, it does not describe what happens on missing/invalid auth, rate limits, or any other behavioral edge cases. Minimal but not misleading.

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, 11-word sentence that front-loads the resource and scope, then adds the login requirement. Every word earns its place; there is no fluff or redundancy.

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 zero parameters, an output schema, and a low-complexity operation, the description is largely sufficient. It covers the essential purpose and auth requirement. It could be slightly more complete by explicitly pointing to a sibling for other users' profiles, but nothing critical is missing.

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 tool has zero parameters and schema description coverage is 100%. Per rubric, zero parameters baselines at 4. The description adds no parameter-level detail because none is needed; there is nothing to document.

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?

Description states a specific verb ('Get'), resource ('Bilibili profile information'), and scope ('your own'), clearly distinguishing it from siblings like get_bilibili_user_info which likely fetch other users' info. The 'your own' qualifier makes the tool's purpose unambiguous.

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 notes that login is required, which gives some context, but it does not explicitly compare this tool to alternatives or state when to use it versus get_bilibili_user_info. Usage is largely implied by the 'my' in the name and the self-profile phrasing, but no explicit routing or exclusion is provided.

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