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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is fully covered structurally. The description adds nothing beyond that — no mention of pagination behavior, page size limits, total result caps (pn max 1000), or whether auth is required for a public endpoint.

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 short sentence with no waste, but it is under-specified rather than genuinely concise; the bracket tag '[发现]' consumes space without adding information for the agent.

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 paginated list endpoint with no output schema, the description should at least explain paging semantics and what a result item looks like. Neither is present, leaving the agent to guess how to page through results or what fields come back.

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 description coverage is 0%, and both parameters (pn, ps) are entirely undocumented in the schema. The description never mentions pagination at all, so the agent cannot infer that pn is a page number or ps is page size without guessing from abbreviations — a clear gap that the description was responsible for filling.

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 gives a concrete verb and resource (读取热门视频列表), so an agent knows this returns a list of trending videos. However, it never distinguishes itself from close siblings like bilibili_search_hot or bilibili_ranking, which could plausibly return overlapping content.

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?

There is no guidance on when to use this versus bilibili_search_hot, bilibili_ranking, or bilibili_my_feed. No prerequisites (login/auth) or exclusions are stated.

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