clickup_send_chat_reply

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

Annotations already declare readOnlyHint=false (write) and destructiveHint=false. Description adds that it posts a reply, returns confirmation with reply id, and lists error codes (400, 404). It does not detail all side effects, but overall sufficient.

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?

Well-structured with clear sections: purpose, when to use/not use, returns, example, error handling. Every sentence is necessary. No fluff.

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?

Covers core usage and error handling but omits explanation of optional parameters. Given the tool's complexity (many optional fields), more detail would help agents use it correctly. Output schema exists, so return values are covered.

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%, so description must compensate. Only 'message_id' and 'content' are mentioned in the example; optional parameters like 'assignee', 'followers', 'workspace_id' are not described. The description adds minimal value beyond the schema for parameter understanding.

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: 'Post a threaded reply under an existing Chat message.' It uses specific verb 'Post' and resource 'threaded reply' and distinguishes from sibling 'clickup_send_chat_message' by stating when NOT to use it.

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?

Explicit when-to-use ('To respond within a message's thread') and when-NOT-to-use ('To start a new top-level message — use clickup_send_chat_message'). Provides clear guidance on alternative tool.

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