list_dial_user_expiry_notices

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

The readOnlyHint annotation already indicates this is a safe read-only operation. The description does not add further behavioral context such as pagination, rate limits, or data freshness. However, for a simple list operation with no parameters, the annotation and description together provide sufficient transparency.

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 states the action and target. There is no redundant or extraneous information, making it highly efficient.

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 the tool's simplicity (no parameters, output schema present, read-only), the description is adequate for understanding its function. It could benefit from clarifying what a 'dial user expiry notice' is, but the output schema likely covers the return structure. Overall, the description is mostly complete.

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 input schema has zero parameters, making parameter semantics irrelevant. The description adds no parameter information, but none is needed. The baseline for zero-parameter tools is 4.

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 '列出拨号用户过期通知' clearly states the tool lists dial-up user expiry notices, using the specific verb 'list' and the resource 'dial user expiry notices'. This distinguishes it from general expiry notice lists such as list_expiry_notices, making the 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 provides no guidance on when to use this tool versus alternatives, nor does it mention any exclusions or prerequisites. The only information is the operation itself, without context about when it is appropriate. No alternatives are named or conditions for selection.

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