Create List in Space

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

Annotations already indicate this is a write operation (not read-only, not destructive). The description adds useful context by specifying the list is folderless, which clarifies the creation scope. However, it does not disclose side effects, required permissions, or return values, leaving some behavioral gaps.

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 a single sentence with no wasted words. It front-loads the main action and context, making it immediately scannable. For its length, every word earns its place.

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 the tool has 7 parameters (2 required) and no output schema, the description is too sparse to be fully contextual. It lacks any indication of what the tool returns, how to handle errors, or what the optional parameters do. The annotations provide some safety context, but the description does not sufficiently cover the operational details an agent needs.

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%, and the description names no parameters. It only hints at the space context through the phrase 'in a ClickUp Space', but does not explain the required 'name' or the optional fields (status, content, assignee, due_date, priority). The description fails to compensate for the 0% schema coverage.

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 (Create), the resource (List), and the scope (folderless in a ClickUp Space), which immediately distinguishes it from the sibling tool create_list_in_folder. The specific term 'folderless' leaves no ambiguity about where the list is created.

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 clearly implies the use case: creating a list directly in a Space rather than in a folder. While it does not explicitly name the alternative 'create_list_in_folder', the contrast is inherent in the word 'folderless'. This provides clear context without exclusions.

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