Pose Library Design

Use this skill when producing pose_library artifacts.

Pose Categories

• Neutral: idle, breathe, listening.
• Attention: look_up, look_down, look_left, look_right.
• Emotion: happy, sad, surprised, worried, determined.
• Action: reach, point, hold, jump, flap, walk_contact, walk_passing.
• Mouth: closed, small_o, wide_open, smile, frown, phoneme-ish shapes.

Acting Pattern

Use timed pose sequences:

anticipation -> action -> hold -> settle

Do not continuously animate every part. Holds make the acting readable.

Pose Data Pattern

{
  "pose": "surprised",
  "parts": {
    "head": { "rotation": -6, "y": -4 },
    "pupil_left": { "x": 4, "y": -6 },
    "mouth": "small_o"
  },
  "hold_frames": 18,
  "transition": "back.out"
}

Quality Checklist

• Required emotions have poses.
• Required actions have poses or cycles.
• Reused cycles have contact and passing poses.
• Poses name only changed parts; defaults come from the rig.
