list_time_plans

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

The annotations declare readOnlyHint=true, which already indicates a safe read operation. The description adds nothing beyond the verb 'list', with no mention of return format, pagination, or other behavioral traits. It does not contradict annotations, but provides no extra value.

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 extremely short, but it is just a restatement of the tool name. It does not earn its place by adding any information, making it an under-specification rather than a concise, value-adding description.

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 (no parameters, read-only, output schema present), but the description leaves the concept of 'time plans' undefined. It doesn't explain what a time plan is, how it relates to other features, or any detail about the listing behavior. The minimal description is not contextually 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 tool has zero parameters and an empty schema. With 0 parameters, the baseline is 4, and there is nothing to explain. The description need not add parameter semantics.

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 '列出时间计划' is a direct translation of the tool name 'list_time_plans', providing no additional information. It merely restates the name without specifying scope, filtering, or differentiating from other list tools, making it a tautology.

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 gives no guidance on when to use this tool versus alternatives. There is no indication of intended scenarios, preconditions, or exclusions, leaving the agent without context for tool selection.

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