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.

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 | $0.00022 | $0.00892 |
| Opus 5 | $0.00011 | $0.00446 |
| Sonnet 5 | $0.00004 | $0.00178 |
| Haiku 4.5 | $0.00002 | $0.00089 |
Grade A, and why
Animation Principles - Deep Dive 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 9d 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.

Complete Animation Principles Reference
Comprehensive technical guide to Disney's 12 principles with implementation details.
1. Squash and Stretch
Definition: Deformation of objects to show flexibility, weight, and motion.
Technical implementation:
- Volume must remain constant (area preserved)
- Stretch along motion path at velocity peaks
- Squash perpendicular to impact surface
- Ratio guidelines: 20-50% for cartoony, 5-15% for realistic
Applications: Facial expressions, body mechanics, object interactions, impact effects.
2. Anticipation
Definition: Preparatory action preceding main action.
Technical implementation:
- Direction opposite to main action
- Duration proportional to action magnitude
- Typical ratio: 1:3 anticipation to action frames
- Can be minimized for surprise effects
Applications: Jumps, throws, emotional shifts, scene transitions.
3. Staging
Definition: Presentation of idea for maximum clarity.
Technical implementation:
- Silhouette test: action readable as solid black shape
- Single focal point per composition
- Background contrast supports subject
- Camera angle serves story point
Applications: Every shot, pose choice, camera placement, lighting design.
4. Straight Ahead and Pose to Pose
Definition: Two fundamental animation approaches.
Straight ahead: Sequential frame creation. Organic, spontaneous, harder to control timing. Pose to pose: Key poses first, breakdowns second, inbetweens last. Controlled, plannable, can feel stiff. Hybrid: Keys pose-to-pose, overlapping elements straight ahead.
5. Follow Through and Overlapping Action
Definition: Continuation of motion after primary action stops.
Technical implementation:
- Drag: appendages trail behind main mass
- Follow through: continuation past stop point
- Overlap: different parts move at different rates
- Settle: oscillating return to rest
Hierarchy: Root leads, extremities follow. Heavy before light.
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.

Animation Principles - Deep Dive is a skill published in the GitHub repository dylantarre/animation-principles (80 stars, last pushed 8mo ago), licensed MIT. It adds 22 tokens to every session and 892 once invoked, about $0.0001 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.
