blender-animation from el4cteo/blender-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add el4cteo/blender-skills/blender-animation@v1.2.0Pins v1.2.0 in mdr.lock. Pin the fingerprint instead.

Animation in Blender 5.2 - slotted/layered actions and the channelbag API, Python keyframing, F-curves, game loops with pop/hitch checks, NLA clips, pose library, mocap/BVH/Mixamo retargeting with auto bone maps, baking control rigs to export skeletons, root motion, per-clip export. Use for any keyframe, action, NLA, mocap, or animation-export task.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Animation
The execution model is in `blender-core` (its `references/bpy-patterns.md` has verified keyframe/driver snippets). Rigs are in `blender-character-rigging`.
## 5.x data model (what changed)
- An **Action** holds **slots** (one per animated ID) and **layers → strips → channelbags → F-curves**. A single action can animate several objects (e.g. a rig and its camera) through different slots.
- Assign: `ob.animation_data.action = act`, then make sure `ob.animation_data.action_slot` is set (picked automatically when a suitable slot exists; otherwise `act.slots.new(id_type="OBJECT", name=ob.name)`).
- F-curves: `cb = anim_utils.action_ensure_channelbag_for_slot(act, slot)`, then `cb.fcurves.ensure(path, index=i, group_name=...)`. `action.fcurves` **no longer exists**.
- The simplest route is still `pb.keyframe_insert("rotation_quaternion", frame=f)`, which creates the action, slot and channelbag.
## Workflow (keyframe animation, studio style)
1. **Blocking**: key poses on every channel (`CONSTANT` interpolation, `bpy.context.preferences.edit.keyframe_new_interpolation_type`) on golden frames (contact, down, passing, up for walks).

How to install
mdr add el4cteo/blender-skills/blender-animation@sha256:74bfbbf2eb941691The line at the top of this page pins the label v1.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
