clickup_task_create

Create new tasks in ClickUp lists with titles, descriptions, assignees, due dates, priorities, and statuses to organize work and track progress.

Instructions

Create a new task in a ClickUp list. The task starts in the list's default status unless 'status' is supplied. Returns the created task object including its new id, which you can pass to clickup_task_update, clickup_task_get, etc.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
assigneesNoUser IDs to assign to the task. Obtain from clickup_member_list or clickup_user_get. Omit for an unassigned task.
descriptionNoTask body. Markdown supported (headings, links, checkboxes, @mentions). Omit to create the task with no description.
due_dateNoDue date as a Unix timestamp in milliseconds (e.g. 1735689600000 for 2025-01-01). Omit for no due date.
list_idYesID of the list the task will live in. Obtain from clickup_list_list (field: id).
nameYesTask title shown in the list view. Required and non-empty.
priorityNoTask priority: 1=Urgent, 2=High, 3=Normal, 4=Low. Omit for no priority.
statusNoStatus name to start in (case-sensitive; must match a status configured on the list). Omit to use the list's default initial status.
tagsNoTag names to apply. Tags must already exist in the parent space (use clickup_tag_list to see available tags or clickup_tag_create to add new ones).
Behavior4/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does well by specifying the default behavior ('starts in the list's default status unless 'status' is supplied') and the return value ('Returns the created task object including its new id'). It also implies this is a write operation through the word 'Create,' though it doesn't mention permission requirements or rate limits.

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?

The description is perfectly front-loaded with the core purpose in the first sentence, followed by important behavioral details and usage context. Both sentences earn their place - the first defines the tool, the second provides critical information about defaults and return values. Zero wasted words.

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?

For a creation tool with no annotations and no output schema, the description does well by explaining the default status behavior and return value format. It could be more complete by mentioning authentication requirements or error conditions, but given the schema's excellent coverage and the description's behavioral details, it's mostly adequate.

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 schema description coverage is 100%, so the schema already documents all 8 parameters thoroughly. The description adds minimal parameter semantics beyond the schema - it only mentions the 'status' parameter behavior. This meets the baseline expectation when schema coverage is high.

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 clearly states the specific action ('Create a new task') and resource ('in a ClickUp list'), distinguishing it from sibling tools like clickup_task_update or clickup_task_get. It explicitly identifies this as a creation operation rather than modification or retrieval.

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 provides clear context about when to use this tool ('Create a new task') and mentions related tools for follow-up operations ('clickup_task_update, clickup_task_get, etc.'). However, it doesn't explicitly state when NOT to use it or provide alternatives for similar creation operations in other contexts.

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