Time Estimates Become Slack Reminders: Plan Focus Time
A task just got a 5-hour estimate in ClickUp. Notis reminds the assignee in Slack: 'This needs 5 hours focused time.' They can block their calendar.
Trigger
Task Time Estimate Updated
Triggers when a task's time estimate is set, changed, or cleared. `changes[]` carries `TimeEstimateChange` entries only; `before` and `after` are millisecond strings or `null`.
Action
Create a reminder
Creates a slack reminder with specified text and time; time accepts unix timestamps, seconds from now, or natural language (e.g., 'in 15 minutes', 'every thursday at 2pm').
Why this helps
Tasks have time estimates in ClickUp but assignees don't know them, so they underestimate complexity and get blindsided by work scope. Context-switching happens mid-task.
- Assignees know scope expectations before starting
- Plan deep work blocks to match estimates
- Reduce scope surprises mid-task
- Help neurodivergent workers estimate focus time accurately
Setup
Build it in a few focused steps.
- 1Connect ClickUp and Slack to Notis via the portal
- 2Create an automation: 'When a time estimate is set on a task in ClickUp, send a Slack reminder to the assignee with the estimate'
- 3Specify reminder timing (immediately, when the task status changes to In Progress, etc.)
- 4Select 'Task Time Estimate Updated' as the trigger
- 5Set a 3-hour estimate on a test task and see the Slack reminder
Questions about this workflow
Should estimates always trigger reminders?
You can filter: 'remind for estimates over 2 hours' or 'remind immediately for all estimates'.
Can we include a 'focus time' action?
Your prompt can say: 'remind them with a calendar link to block the time'—Notis will adapt to available Slack integrations.
What if the estimate changes?
Notis sends an updated reminder when the estimate changes, so the assignee always has current scope info.
