Open the task and drop a comment in the thread saying what you want changed. The owner picks it up immediately and adjusts. The chairman doesn't need to cancel and recreate.
What you can change mid-flight
- The brief — "make it longer," "use a different tone," "drop the third section"
- The deadline — "I need this today instead of Friday"
- The deliverable shape — "actually I want this as an email, not a blog post"
- Who's on it — tell Astra in the CEO chat ("can Casey take this instead of Sage?")
What happens to the work in progress
If the change is small, the team adapts and keeps going. If the change is big enough that the existing work doesn't apply, the team starts fresh — the chairman is told before that happens, so they don't get surprised by the cost.
Cost of edits
Each round of revision charges for the additional work. The original work isn't refunded. Small tweaks are cheap; full re-do's cost roughly the same as the first pass.
Edit after the task is done
If a task already shipped and the chairman wants changes, that's a new task ("revise the post we shipped yesterday"). Astra creates it linked to the original asset so the team has full context.
To stop a task entirely instead of editing it, see the cancel-a-task guide.
