Create tasks

create_task

Create one or multiple ClickUp tasks in a single call, passing an array to turn discussion items into a backlog. Each task reports individually so one failure doesn't stop the rest.

Instructions

Create one or many tasks in one go — pass the whole array when breaking a discussion into a backlog, rather than calling this repeatedly. Each task is reported individually; one failure does not abort the rest.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Behavior4/5

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

With no annotations, the description must disclose behavior on its own. It reveals that each task is reported individually and that a single failure does not abort others, which is valuable operational knowledge. It does not go into idempotency or permissions, but this partial-failure semantics raises it above a bare 'create' statement.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence conveys creation, batch capability, a use case, and failure behavior—no redundant words. Well structured.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the nested array schema and absence of output schema, the description gives the critical behavior (non-atomic batch creation) and a use case. It does not elaborate on return format beyond 'reported individually', but that suffices given the simplicity. It hints at when to use it (backlog creation) but doesn't cover all preconditions.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description mentions 'the whole array' but not individual fields. The schema provides descriptions for parent, status, list_id, due_date, priority, and assignees, so the bulk of parameter meaning comes from the schema. The description adds only the batch nuance, hence a mid score.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses the verb 'Create' with 'tasks' and clarifies scope ('one or many in one go'). It distinguishes from repeated calls by suggesting array usage, which separates it from other task operations. The example use case ('breaking a discussion into a backlog') further anchors its purpose.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description tells the agent to pass the whole array and avoid repeated calls, implying batch creation is preferred. It does not explicitly name alternative sibling tools, so exclusions are absent. The context is clear for the creation scenario.

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