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

Annotations already flag readOnly=false and destructive=false, so the description's 'Create' is consistent. However, idempotentHint=true contradicts the implication that each call creates a distinct task. The description adds return value info but lacks deeper behavioral context like rate limits or authentication requirements beyond the API key parameter.

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?

Two sentences, front-loaded with purpose, then inputs and outputs. Every sentence is valuable with no waste.

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?

With an output schema present, the description sufficiently covers inputs and outputs. However, the mention of a non-existent 'assignee' parameter creates a gap, and the description does not explain the idempotency hint or the openWorldHint.

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 baseline is 3. However, the description mentions 'assignee' as an optional parameter, but the schema does not include any assignee property. This discrepancy undermines clarity and could mislead an agent. The description adds no additional meaning beyond the schema's own parameter descriptions.

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 verb 'Create' and resource 'task in a ClickUp list', specifies required inputs, and distinguishes from sibling tools like clickup_get_task and clickup_list_tasks.

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?

While it doesn't explicitly state when to use or not to use, the context is clear: it's for creating a new task. The sibling list contains no other creation tools for tasks, so ambiguity is low.

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