send_chat_message_event_by_id_api_v1_chats

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

With no annotations, the description bears full responsibility for disclosing behavior. It merely states 'Send', implying a mutation, but does not specify whether this is a write operation, what side effects occur, or if authentication is required. The lack of detail leaves the agent guessing about safety and impact.

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 short (6 words), but this brevity reflects under-specification rather than conciseness. It fails to earn its place by providing any actionable information beyond the name.

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?

Despite having an output schema, the tool has 4 required parameters with no schema descriptions, no annotations, and a description that adds no context. For a tool of this complexity (nested objects, event semantics), the description is grossly incomplete.

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%, meaning none of the 4 required parameters (id, message_id, data, type) are explained. The description itself adds zero semantic value—it does not describe what each parameter represents or how they should be used. The agent must infer from names alone.

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 'Send Chat Message Event By Id' is essentially a restatement of the tool name and does not clarify what constitutes a 'chat message event' versus a regular message. Among siblings like post_new_message_api_v1_channels and update_chat_message_by_id_api_v1_chats, it fails to differentiate its purpose.

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 usage guidance is provided. The description does not indicate when to use this tool over alternatives such as post_new_message_api_v1_channels or update_chat_message_by_id_api_v1_chats, nor does it mention any prerequisites or context.

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