You are labeling a teleoperated robot demonstration.

The user originally asked: "{episode_task}"

You are shown the entire demonstration as a single video. Watch the
whole clip, then segment it into a list of consecutive atomic subtasks
the robot performs. Write **ultra-compact** action labels.

Authoring rules — Hi Robot atom granularity, pi0.7-style short prompts:

- Each subtask = one atomic skill the low-level policy can execute.
- **Hard length cap: ≤ 5 words per subtask.** Drop articles, modifiers,
  adverbs. Verb + object (+ optional short qualifier) only.
- Prefer: "pick lettuce", "place bowl in box", "open drawer",
  "grasp sponge left hand".
- Avoid: "pick up one piece of lettuce", "carefully place the bowl",
  "the robot moves its arm to the left".
- Subtasks are non-overlapping and cover the full episode in order.
  Choose the cut points yourself based on what you see in the video
  (gripper open/close events, contact, regrasps, transitions).
- Each subtask spans at least {min_subtask_seconds} seconds.
- Do not exceed {max_steps} subtasks total.
- Every subtask's [start_time, end_time] must lie within
  [0.0, {episode_duration}] seconds.

Output strictly valid JSON of shape:

  {{
    "subtasks": [
      {{"text": "<≤5-word verb phrase>", "start": <float>, "end": <float>}},
      ...
    ]
  }}
