get_prewarm_pop_points

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states the action without describing read-only nature, authentication needs, rate limits, error behavior, or impact. This is insufficient for an agent to understand side effects.

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 sentence that directly states the tool's purpose. No redundant or unnecessary information, making it highly concise and well-structured.

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?

For a simple list tool with one parameter and no output schema, the description is basic but could be more complete. It does not explain what POP nodes are or what the return format looks like, leaving some ambiguity for the agent.

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 one parameter 'region' with a description '区域标识', which is clear. Schema description coverage is 100%, so the description does not need to add much. It adds no further semantics but is not deficient either.

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 name 'get_prewarm_pop_points' and description '获取预热区域的 POP 节点列表' clearly state that the tool retrieves a list of POP nodes for a prewarm region. It distinguishes itself from the sibling 'get_prewarm_regions' which likely returns regions rather than nodes.

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 implies usage: provide a region to get POP nodes. However, it does not explicitly state when to use this tool over alternatives like 'get_prewarm_regions', nor does it mention prerequisites or exclusions. The guidance is adequate but not thorough.

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