clickup_get_chat_message_replies

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

With no annotations, the description carries the disclosure burden and does well: it reveals pagination support and the non-obvious behavior that the id may be a reply inside the thread rather than the root, which explains empty results. It omits permission/auth requirements and response shape, keeping it just short of full disclosure.

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?

Front-loaded with the core action, then the URL/routing caveat, then the fallback. Every clause is functional, though the parenthetical listing two URL shapes is dense and could be trimmed slightly.

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?

For a paginated read tool with no output schema, the description covers the ambiguous input case, the pagination capability, the sibling to avoid, and the recovery step when results are empty. An agent has everything needed to call it correctly.

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 coverage is 100%, so the baseline is 3, but the description adds real meaning beyond the schema for message_id: where the id comes from (chat thread URLs), and that it may resolve to a reply rather than a thread root. The remaining params (limit, cursor, content_format, workspace_id) are left entirely to the 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?

States a specific verb and resource ('Get threaded replies for a chat message') plus the keying parameter (message_id). It also explicitly contrasts itself with clickup_get_task and clickup_get_chat_channel_messages, so the agent can separate it from the nearest siblings without reading schemas.

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?

Gives concrete routing rules: chat thread URLs end in a message id and should be passed here, not to clickup_get_task. It also supplies a fallback path — if no replies return, use clickup_get_chat_channel_messages on the channel to find the thread root.

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