Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00036 | $0.01024 |
| Opus 5 | $0.00018 | $0.00512 |
| Sonnet 5 | $0.00007 | $0.00205 |
| Haiku 4.5 | $0.00004 | $0.00102 |
Grade A, and why
3d-spatial scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

3D Spatial Animation
Apply Disney's 12 animation principles to 3D software, VR/AR, and spatial computing environments.
Quick Reference
| Principle | 3D/Spatial Implementation |
|---|---|
| Squash & Stretch | Lattice deformers, blend shapes |
| Anticipation | IK/FK wind-ups, camera pre-motion |
| Staging | Camera angles, lighting, depth |
| Straight Ahead / Pose to Pose | Layered animation vs blocking |
| Follow Through / Overlapping | Bone chains, physics simulation |
| Slow In / Slow Out | F-curve editing, animation curves |
| Arc | IK handles, motion paths in 3D space |
| Secondary Action | Cloth sim, particle systems, environment |
| Timing | Frame timing, VR 90fps requirements |
| Exaggeration | Stylized deformation, pushed poses |
| Solid Drawing | Volume preservation, silhouettes |
| Appeal | Character design, satisfying motion |
Principle Applications
Squash & Stretch: Use lattice or mesh deformers for organic squash. Blend shapes for facial deformation. Scale bones in hierarchies. Always preserve volume—if Y compresses, X/Z expand.
Anticipation: IK rig wind-ups for character animation. Camera pulls back before push-in. Objects coil before release. VR: telegraph actions clearly for user comfort.
Staging: Camera angle sells the action. Three-point lighting directs focus. Depth of field isolates subjects. In VR, use spatial audio and lighting to guide attention.
Straight Ahead vs Pose to Pose: Block key poses first (pose to pose), then refine (spline). Use layered animation—body first, then overlapping elements. Procedural secondary motion is straight ahead.
Follow Through & Overlapping: Bone chains for tails, hair, capes. Physics simulation for cloth and particles. Delay child bones from parents. Jiggle deformers for organic follow-through.
Slow In / Slow Out: F-curves (Blender), Animation Curves (Unity), Graph Editor (Maya). Tangent handles control easing. Flat tangents = slow, steep = fast. Never leave curves linear.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

3d-spatial is a skill published in the GitHub repository dylantarre/animation-principles (79 stars, last pushed 8mo ago), licensed MIT. It adds 36 tokens to every session and 1,024 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

Make a 3D model animation-ready — add a humanoid skeleton and skin weights to an existing GLB, or generate a rigged avatar from text/images in one call. Use when you or the user want to rig a mesh, auto-rig a GLB, make a model animatable, get a character that plays idle/walk animations, or go from prompt straight to a…

Reverse-engineer any motion reference (a video from X/Twitter, Dribbble, a screen recording, a GIF) into production animation code through frame-level dissection. Use when the user shares a video/URL and says "implement this animation", "recreate this motion", "port this interaction", "how does this animate", "clone…
