Break one step into tickable subtasks
Some steps are really several small actions. Add subtasks and your team gets a short, tickable list right inside the step — so nothing in the “obvious” part of the work quietly gets skipped.
Start your free trial. No credit card required.
Detail without a wall of steps
You could split every little action into its own step — but then a five-minute task reads like a twenty-step procedure. Subtasks keep the step list clean while still spelling out the small moves inside a step, so newer teammates know exactly what “done” means.
- “Prep the room” — and hope everyone remembers what that means
- The little things get skipped under time pressure
- No way to see which parts actually got done
- Each small action is spelled out and tickable
- Optionally, none of them can be skipped
- Every tick shows who did it and when
From workflow template to ticked-off run
Add subtasks to a step
Open any step in your Workflow, add a subtask, type its title, and add more. Drag to reorder the list until it reads the way the work actually happens.
Start a Run
Every time you run the Workflow, that step arrives with its own fresh copy of the subtasks — ready for this run, unchecked and waiting.
Tick them off
Whoever is working the step checks each subtask as they go. If you want, the step can't be marked complete until the whole list is done.
Make the whole list a requirement
Flip on Require list completion before completing step and the step becomes a real gate: it won't complete until every subtask is checked. Try to finish early and Manifestly stops you with a clear reason instead of letting a half-done step slip through.
- Set it per step — require the list on the steps that matter, leave it optional elsewhere.
- The same rule guards approval steps: an approver can't sign off with subtasks still open.
- Leave it off for a gentle guide the team can tick at their own pace.
Every tick is on the record
A subtask isn't just a checkbox that flips — when someone checks it, Manifestly stamps who completed it and when. Completed items show struck through with a completion note, and each check, un-check, and edit is captured in the run's activity. Un-check a subtask and it drops back onto the list, no drama.
- Completion is attributed to the exact person who ticked it.
- Timestamps and edits land in the run activity feed for a clean audit trail.
- Titles auto-link URLs and support the same tokens as your step content.
Subtask or step? A simple rule of thumb
Reach for a subtask when…
- The actions all belong to one person, in one sitting.
- You just need a reminder of the small moves, not separate tracking.
- You want the step list to stay short and readable.
Reach for a full step when…
- It needs its own assignee, due date, or approval.
- It should capture data in a form field.
- It gates later steps or drives conditional logic.
Check them off from anywhere
Subtasks aren't stuck in the browser. Tick them from Slack while you work, or complete them programmatically through the v2 API — the same endpoints AI agents use over MCP to work a run to plan.
- Complete or un-complete a subtask and the required-list gate updates with it.
- Agents see the same list, titles, positions, and completion state you do.
# Mark a subtask complete on a run step
POST /api/v2/runs/812/run_steps/6/subtasks/42
{ "action": "complete" }
# → response records who and when
{
"id": 42,
"title": "Log serial numbers",
"completed_at": "2026-08-10T09:15:04Z",
"completed_by_id": 137
}
Where a subtask list earns its keep
Setup & prep steps
A single “get the space ready” step with the small checks folded in.
Test the A/V, lay out materials, set out refreshments — all ticked before the step closes.
Inspections & QA
A verification step that must not be finished with anything skipped.
Require the list so a shipment can't be signed off until every check is done.
Onboarding touches
The little welcome tasks that ride along with one bigger step.
Confirm details, send the packet, schedule the check-in — each attributed to who did it.
