Execute

Update plan.md: If the plan was loaded from plan.md, update the file directly — change - [ ] to - [x] for each completed subtask. This keeps the file in sync with actual progress so that future sessions can resume from where you left off.

Batch Size

• By default, execute up to M size worth of subtasks in one batch, then pause and ask the user whether to continue.
  • For example, if there are three consecutive S subtasks, execute up to two or three of them (roughly M equivalent) before pausing.
  • If a single subtask is M, execute that one subtask and then pause.
  • XS and S subtasks can be grouped together as long as their combined effort does not exceed M.
• If the user explicitly requests a larger batch (e.g. "do all of them", "keep going until done", "execute through step 3"), follow that instruction.

Guidelines

• Follow the plan's order and scope. Do not add work beyond what the plan specifies.
• Keep each step's changes focused and minimal — one subtask at a time.
• If the plan turns out to be wrong or outdated mid-execution, stop and discuss with the user before continuing.
