mission rerun requires --task <id>.

Error message

mission rerun requires --task <id>.

What it means

Post-parse validation: the rerun action was selected but no --task id was provided. rerun re-executes exactly one task, so the id is mandatory.

Solutions

  1. Add --task <id>: mission rerun mission.md --task t1
  2. Verify the task id exists in the summary via mission status --json
  3. Use resume (not rerun) to continue an interrupted mission

Example fix

# before
mission rerun mission.md
# after
mission rerun mission.md --task t1
Defensive patterns

Strategy: validation

Validate before calling

if (action === 'rerun' && !args.includes('--task') && !args.some(a => a.startsWith('--task='))) {
  failEarly('rerun requires --task <id>');
}

Prevention

When it happens

Trigger: `mission rerun mission.md` with no --task flag, or --task given without a value so it isn't recorded.

Common situations: Assuming rerun re-runs all failed tasks; --task at the end of the command with the value missing or swallowed by another flag.
