 {vocabulary_block}Authoring rules — Hi Robot atom granularity, pi0.7-style short prompts:
 
-- Each subtask = one atomic skill the low-level policy can execute.
-- Write each subtask as an IMPERATIVE COMMAND, starting with a verb:
-  move, reach, pick up, grasp, place, put, push, pull, open, close,
-  turn, press, lift, insert, pour...
+- Each subtask = one COMPOSITE atomic skill the low-level policy can
+  execute end-to-end. A "skill" bundles its own approach motion with
+  its terminal action — do NOT split the approach off as its own
+  subtask. The whole-arm policy already learns to reach as part of
+  every manipulation primitive.
+- Write each subtask as an IMPERATIVE COMMAND, starting with one of
+  these verbs (extend only when none fits):
+    pick up <obj>           — approach + grasp + lift in one subtask
+    put <obj> on/in <loc>   — transport + release in one subtask
+    place <obj> on/in <loc> — synonym of "put"; pick one and stay consistent
+    push <obj>              — contact + linear shove
+    pull <obj>              — contact + linear retract
+    turn <knob/dial/handle> — rotary actuation
+    press <button>          — single-press contact
+    open <drawer/door/lid>  — full open motion
+    close <drawer/door/lid> — full close motion
+    pour <src> into <dst>   — tilt + flow
+    insert <obj> into <slot>— alignment + push-fit
+    go to <loc>             — ONLY when no grasp / actuation follows
+                             (e.g. a pure relocation between phases).
+                             If the next subtask grasps something at
+                             that location, drop "go to ..." and just
+                             write "pick up ..." instead.
+- Forbidden ultra-fine splits — the VLM is NOT allowed to emit these
+  as standalone subtasks; fold them into the parent composite:
+    "move to X"   → fold into "pick up X" (or whatever follows)
+    "reach for X" → fold into "pick up X"
+    "grasp X"     → fold into "pick up X"
+    "lift X"      → fold into "pick up X" (or "put X on Y" if it's
+                    the transport phase of a place)
+    "release X"   → fold into "put X on Y" (or "place X in Y")
 - Keep it SHORT — a verb phrase, not a sentence. Drop articles
   ("the", "a") and adverbs ("carefully", "slowly"). Add a "how"
   detail (which hand, which grasp point) ONLY when it is needed to
-  disambiguate.
+  disambiguate. Every subtask must begin with one of the verbs
+  above (no leading nouns, no "then", no "first").
 - NEVER use third person. Never write "the robot", "the arm", "the
   gripper moves", "it picks up" — the robot is implied. Command it,
   do not describe it.

+- Each subtask spans at least {min_subtask_seconds} seconds. If a

+- Do not exceed {max_steps} subtasks total. Fewer, larger composites
+  are preferred over many micro-steps.
 - Every subtask's [start_time, end_time] must lie within
   [0.0, {episode_duration}] seconds.
