get_notifications

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

The description only says 'get' which matches the readOnlyHint annotation, so there is no contradiction. However, it discloses no additional behavioral traits such as filtering, ordering, pagination, or whether the list is sorted or limited. With annotations present, the bar is lower, but the description adds no value beyond the annotation.

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 a single, concise sentence that immediately conveys the operation. It is front-loaded and contains no filler, earning a perfect score for efficiency.

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?

The tool is simple with no parameters, but the description is too sparse to be actionable in a rich context with many sibling tools. It doesn't clarify what type of notifications are returned, how they are generated, or whether they are system alerts or user messages, making it incomplete for effective selection.

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?

There are zero parameters, and the schema coverage is 100%, so the description need not explain parameters. The baseline of 4 is appropriate since no parameter information is needed.

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 clearly states the action (获取/get) and the resource (消息通知列表/message notification list), making the tool's purpose clear. However, it does not differentiate from sibling tools like get_notification_log or get_messages, which also relate to notifications.

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 is provided on when to use this tool versus alternatives. The description offers no context, prerequisites, or examples, leaving the agent to infer usage from the name alone.

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