List Periodic Notices

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

The annotation readOnlyHint=true already establishes this as a safe, non-mutating read. The description adds nothing beyond that: no indication of scope, filtering, ordering, or result size. With annotations covering the safety profile, the description still fails to contribute any extra behavioral context.

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 phrase is maximally efficient, but in this case the brevity reflects under-specification rather than tight writing. It is front-loaded and waste-free, yet the space saved was not redeployed into useful routing or scoping information.

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?

Because the tool is parameterless, read-only, and has an output schema, very little description is strictly required. Still, the crowded sibling set of notice-listing tools means the description should say which notice category this returns, and it does not; that omission leaves a real gap for correct tool 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?

The tool takes zero parameters and the input schema is empty with additionalProperties=false, so there are no parameter semantics to explain. Per the baseline for zero-parameter tools, a 4 is appropriate; the description neither helps nor harms here.

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 phrase "列出定期通知" names a verb (list) and a resource (periodic notices), so the basic operation is understandable. However, it offers no differentiation from the closely related sibling tools list_realtime_notices, list_expiry_notices, and list_dial_user_expiry_notices, all of which are notice-listing tools. An agent must guess which notice family it actually needs.

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 when-to-use guidance, no exclusions, and no mention of the alternative notice-list tools in the sibling set. The description gives no signal about when periodic notices are the right choice versus realtime or expiry notices.

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