create_chat_message_reply

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

The description states the action and return value but fails to disclose important behavioral traits such as required permissions, error conditions (e.g., if the parent message doesn't exist), or any side effects. With no annotations available, the description carries the full burden but is insufficient.

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 two sentences, direct, and contains no unnecessary information. Every sentence adds value: the first states the purpose, the second states the return value.

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 4 parameters and no output schema, the description provides the core purpose and return value. However, it lacks details on permissions, error handling, and the format of the reply id. It is adequate but not complete for a creation tool.

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?

All four parameters are described in the schema (100% coverage). The description adds context about the response ('Returns the created reply with its id'), but does not significantly enhance the understanding of parameters beyond the schema. Baseline score of 3 is appropriate.

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 action ('Reply to a Chat message'), the resource ('Chat message'), and specifies it creates a threaded response. It also distinguishes itself from siblings by mentioning ClickUp Chat v3 and the unique operation of creating a reply.

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 implies usage ('Reply to a Chat message') but does not explicitly state when to use this tool versus alternatives like 'send_chat_message' or 'create_chat_direct_message'. No exclusions or context about when not to use it are provided.

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