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 | $0.00026 | $0.01248 |
| Opus 5.5 | $0.00010 | $0.00499 |
| Sonnet 5.5 | $0.00005 | $0.00250 |
| Haiku 4.5 | $0.00003 | $0.00125 |
Grade A, and why
universal-fallback 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 1mo 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.

Universal Animation Principles
Disney's 12 animation principles applied generically across any medium or context.
Quick Reference
| Principle | Universal Application |
|---|---|
| Squash & Stretch | Show impact and flexibility |
| Anticipation | Prepare before action |
| Staging | Direct attention clearly |
| Straight Ahead / Pose to Pose | Continuous vs keyframe approach |
| Follow Through / Overlapping | Elements complete at different rates |
| Slow In / Slow Out | Ease acceleration/deceleration |
| Arc | Natural curved motion paths |
| Secondary Action | Supporting elements reinforce primary |
| Timing | Duration affects perceived weight |
| Exaggeration | Push for clarity and impact |
| Solid Drawing | Maintain form and structure |
| Appeal | Design for engagement and delight |
The 12 Principles Explained
1. Squash & Stretch
Objects deform during action to show impact, weight, and flexibility. Volume remains constant—compression in one axis means expansion in another. The most important principle for showing life and physics.
Application: Anything with mass reacts to force. Soft objects deform more. Rigid objects show less but still respond. Use to show weight, speed, and material properties.
2. Anticipation
Preparation before the main action. Wind-up before pitch. Crouch before jump. Pullback before push. Prepares the audience for what's coming and makes action more readable.
Application: Major actions need setup. The bigger the action, the bigger the anticipation. Can be physical, visual, or timing-based. Skipping anticipation makes motion feel robotic.
3. Staging
Directing attention to what matters. Composition, contrast, motion, and timing work together to make intent clear. One clear idea per moment.
Application: Audiences can only focus on one thing at a time. Use all available tools (position, lighting, motion, timing) to make the important element unmistakable.
4. Straight Ahead & Pose to Pose
Two animation approaches. Straight ahead: draw frame-by-frame for fluid, spontaneous motion. Pose to pose: define key poses, then fill between for control and clarity. Most work combines both.
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.

universal-fallback is a skill published in the GitHub repository dylantarre/animation-principles (117 stars, last pushed 9mo ago), licensed MIT. It adds 26 tokens to every session and 1,248 once invoked, about $0.0001 per session on Opus 5.5. 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.
