wechat_send_multiple_messages

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

No annotations are provided, so the description carries the full behavioral disclosure burden. It only says messages are sent consecutively, without covering delivery timing, ordering guarantees, rate limits, authentication needs, or failure behavior, though the schema does document a delay parameter.

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, front-loaded sentence with zero wasted words. It clearly and efficiently conveys the core purpose without redundancy.

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 tool with four parameters and no annotations, the description is too sparse. While an output schema exists so return values need not be explained, behavioral details such as what 'consecutive' means operationally, how the delay works, and how search_pages affects the send are left entirely to the schema or omitted.

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 description coverage is 100%, so all four parameters are already fully documented in the input schema. The description adds no additional parameter meaning beyond what the schema provides, matching the baseline score for high-coverage schemas.

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 states a specific verb (发送) and resource (多条消息) with a clear scope constraint (单个好友或群聊). It implicitly distinguishes itself from the sibling wechat_send_to_multiple_friends (multiple recipients) and wechat_send_message (single message), but does not name either alternative explicitly.

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?

Usage is only implied: use this tool when sending multiple messages to one chat. The description offers no explicit when-to-use guidance, no prerequisites, and no direct comparison to the single-message sibling wechat_send_message.

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