clickup_comment_reply

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

With no annotations, the description carries full burden. It mentions that replies appear indented and returns the created object with id, but lacks details on auth requirements, rate limits, or side effects like notification behavior (though schema covers assignee notification).

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 with three sentences, each adding essential information: action, behavior, and alternative. No unnecessary 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 no output schema and 100% parameter coverage, the description sufficiently explains the tool's purpose, behavior, and return value (new id). It lacks explicit mention of prerequisites like having a valid parent comment_id, but that is inferred from the parameter description.

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 three parameters are fully described in the schema with 100% coverage. The description adds no extra meaning beyond what is already in the schema, so a 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 ('Post a threaded reply'), the resource ('under an existing ClickUp comment'), and distinguishes itself from the sibling tool clickup_comment_create by specifying that it is for replies, not top-level comments.

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 explicitly tells when to use this tool (for threaded replies) and provides a direct alternative for a common scenario ('For a top-level comment, use clickup_comment_create instead'), guiding the agent away from misuse.

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