animation-editing

Preview, validate, and bake bone-rotation edits on AnimSequences with constraint awareness and retarget safety. Use when the user asks to edit/pose/adjust an animation's bones, raise an arm, create a swing/wave/dance/pose, mirror or copy a pose, set joint limits, or learn bone constraints. Load together with animsequence (keyframes) and skeleton (structure).

animsequence

Create and edit AnimSequence keyframes and tracks — add/remove keyframes, set bone tracks, query sequence info, and bake edits (AnimSequenceService). Use when the user asks to create a new animation sequence, add keyframes/tracks, or edit raw animation data. For constraint-aware bone posing, also load animation-editing.

blueprints

Create and modify Blueprint assets, variables, functions, components, event dispatchers, and interfaces. Use when the user asks to create a Blueprint/BP, add a variable or component to a Blueprint, make an event dispatcher/delegate, implement a Blueprint interface, or inspect a Blueprint's class/components. For node-level graph wiring, also load blueprint-graphs.

behavior-trees

Create, inspect, and edit Behavior Tree and Blackboard assets — composites, tasks, decorators, services, node properties, blackboard key bindings, key CRUD and metadata, tree round-trips and validation (BehaviorTreeService + BlackboardService). Use when the user asks to build a Behavior Tree, add BT nodes or decorators, bind blackboard keys, author a blackboard, or validate/repair a BT asset.

Animation Editing Skill

Covers the profile → preview → validate → bake workflow for safe bone edits with correct bone-space handling and constraint validation.

Load companion skills: animsequence (basic keyframe creation), skeleton (structure, retargeting), animation-blueprint (state machines / AnimGraph). Skills load via the engine's AgentSkillToolset (ListSkills / GetSkills) — there is no vibeue-skills-manager tool. Run the VibeUE services below with execute_python_code (unreal.<Service>.<method>()).

🛡️ Safe discovery — never unreal.load_asset() in loops (memory crash 0xC0000005). Use SkeletonService.list_skeletons(path), AnimSequenceService.find_animations_for_skeleton(skeleton), AnimSequenceService.list_anim_sequences(path, skeleton_filter) — they query metadata without loading.

⚠️ Critical Rules

1. Always specify bone space

Every bone rotation must state its coordinate space. Default to "local" for user intent.
