File-backed plans make coding agents resumable

planning-with-files gives coding agents a Markdown planning system so task state, gates, and progress survive context resets, crashes, and handoffs. Why it matters: Long-running agent work often fails when the plan lives only in chat context. A file-backed plan creates a durable execution record that another session or reviewer can inspect.

Try this: Run a small coding task with a required plan file, explicit completion gates, and a final check that the implementation matches the saved plan.
