get_delivery_time_slots

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

No annotations provided, so the description should disclose side effects. It describes the API call and return structure, implying a read operation, but does not explicitly state read-only or mention auth requirements. Adds value with endpoint and return format.

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 structured with sections and is concise. It front-loads the main purpose. However, the parameter section is missing, slightly reducing 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?

For a simple 1-parameter tool with no output schema, the description provides the API endpoint, return structure, and usage examples. It covers the essential aspects, though it lacks error handling or pagination details.

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?

Schema coverage is 0%, and the description only indirectly refers to the parameter as '指定配送方式' (specified delivery method). It does not explain how to obtain the delivery_option_id or any constraints, offering minimal additional meaning.

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 tool retrieves available time slots for a specified delivery method. It provides usage examples and differentiates from siblings like get_delivery_option_detail by focusing on time slots.

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 context for using the tool (confirming slots, analyzing preferences) but does not explicitly mention when not to use it or suggest alternative tools. It lacks exclusion criteria.

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