send_my_chat_message

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

No annotations are present, and the description does not disclose behavioral traits beyond the basic action. It does not mention idempotency, required permissions, side effects, or what the output schema returns, leaving significant gaps.

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 concise: a single sentence followed by a clear args list with no redundancy. Every sentence adds value, and the format is front-loaded with the main action. No wasted words.

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 presence of an output schema (though not shown), the description does not need to explain return values. However, it lacks context about when to use this tool over other message-related tools (e.g., create_agent_chat_message). It also fails to clarify whether the message is sent to all chat participants or only those mentioned, leaving ambiguity.

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?

With 0% schema description coverage, the description effectively explains all three parameters. It adds meaningful constraints, especially for 'recipients' (non-empty, comma-separated, at least one name). For 'chat_id' and 'content', it provides basic context ('The chat room ID', 'Message text') that adds value beyond the schema's type-only definitions.

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 action: 'Send a message in a chat room.' It uses a specific verb and resource, making the purpose clear. However, it does not differentiate from sibling tools like create_agent_chat_message or list_my_chat_messages, which could cause confusion.

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 guidance is provided on when to use this tool versus alternatives, such as when to send vs create a message. The description imposes a constraint on recipients (non-empty) but does not explain the intended context for this tool.

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