bilibili_anime_home

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

With no annotations provided, the description carries the burden of behavioral disclosure. It does disclose that the tool operates anonymously and excludes personalized feed items, which is useful. However, it does not mention authentication requirements, rate limits, or the structure of the returned data. Given the simplicity of the tool, this is adequate but not exhaustive.

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, front-loaded with the verb and resource, and lists the returned content types plus an exclusion. Every word earns its place; there is no redundancy or fluff.

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 no-parameter, no-output-schema tool, the description covers what the agent needs to know: what data is returned (the sections) and what is excluded. It does not describe the output format, but that is likely acceptable for a simple home-sections tool. The description is sufficient for calling the tool correctly, though not exhaustive.

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, so the description need not explain parameter meaning. The schema is empty and the description correctly does not attempt to document parameters. This aligns with the baseline of 4 for no-parameter tools.

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 states a clear purpose: 'Get Bilibili anime home sections' and enumerates the content returned (featured titles, latest updates, schedule, popular ranking, new recommendations). It also notes an exclusion (personalized rotating feed items), which adds specificity. However, it does not explicitly distinguish itself from sibling tools like bilibili_popular or bilibili_ranking, relying on the term 'home' to imply a broader scope.

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 a general, anonymous home-section use case but does not explicitly state when to use this tool over alternatives such as bilibili_popular, bilibili_ranking, or bilibili_guochuang_home. It lacks any 'use this when' or 'instead of' guidance, leaving the agent to infer the appropriate context from the content list.

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