leave_chat

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

The description explains the delete_history behavior: it clears local history without affecting the other party. However, it does not elaborate on the irreversible nature of leaving a chat or the potential need for permissions.

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 short and to the point, with two sentences plus an argument list. It is well-structured for its size, though the argument format could be more integrated.

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?

Given the tool's simplicity and the presence of an output schema, the description adequately covers the relevant details. It explains the parameters and their effects, making it complete for this task.

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 0%, but the tool description fully explains both parameters: 'chat' is the conversation, and 'delete_history' clears local history only. This adds essential meaning beyond the raw schema.

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's purpose: to exit a group/channel or delete a private chat. It uses specific verbs ('退出' and '删除') and distinguishes from siblings like 'delete_chat'.

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?

No explicit when-to-use or when-not-to-use guidance is provided. The purpose is straightforward, but the description could mention that this tool is for leaving conversations rather than managing them.

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