bilibili_session_notifications

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

No annotations are provided, and the description only says '获取通知和设置信息' with a vague Returns clause. It does not disclose side effects, auth requirements, rate limits, or the structure of the returned data, leaving the behavioral profile under-specified.

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 concise and front-loaded with the purpose, followed by an Args list and a Returns line. It avoids excessive prose, though the Returns section is vague and the arg description somewhat duplicates the schema enum.

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?

With three distinct return modes (unread, system, settings), the description gives no details on the shape or content of each return type. There is no output schema and no annotations, so the description should carry more weight but does not.

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 description adds meaning to the single parameter by explicitly defining each enum value: unread=未读消息数量统计 (unread count), system=系统消息列表 (system message list), settings=消息设置 (message settings). This goes beyond the schema's bare enum names and compensates for the 0% schema description coverage.

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 '获取通知和设置信息' (get notifications and settings info), and the Args section clarifies three notification types. It clearly indicates a retrieval action for notifications/settings, but it does not explicitly differentiate from sibling notification-related tools.

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?

No guidance on when to use this tool versus alternatives. It does not mention any sibling tools or provide context for when to prefer this over bilibili_session_list or other notification-related tools.

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