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 | $0.00024 | $0.00529 |
| Opus 5 | $0.00012 | $0.00264 |
| Sonnet 5 | $0.00005 | $0.00106 |
| Haiku 4.5 | $0.00002 | $0.00053 |
Grade A, and why
Animation Principles - Quick Start 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 6d 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.

12 Animation Principles in 5 Minutes
The Disney animators codified these principles in the 1930s. They still define quality animation today.
The Principles (30 seconds each)
1. Squash and Stretch Objects compress on impact, elongate in motion. A bouncing ball flattens when it hits ground. Gives life and flexibility.
2. Anticipation Wind-up before action. Crouch before jump. Arm back before throw. Prepares the viewer for what's coming.
3. Staging Present ideas clearly. One idea per shot. The viewer should never wonder where to look.
4. Straight Ahead / Pose to Pose Two animation methods. Straight ahead: draw frame by frame for fluid, spontaneous motion. Pose to pose: draw key frames first for controlled, planned action.
5. Follow Through / Overlapping Action Things don't stop all at once. Hair keeps moving after head stops. Different parts move at different rates.
6. Slow In and Slow Out Movement accelerates and decelerates. More drawings at start and end, fewer in middle. Creates natural weight.
7. Arc Natural motion follows curved paths. Arms swing in arcs. Heads turn in arcs. Straight lines feel robotic.
8. Secondary Action Supporting movements that add richness. Walking while whistling. Talking while gesturing. Enhances without distracting.
9. Timing Number of frames = speed and weight. Fewer frames = faster/lighter. More frames = slower/heavier.
10. Exaggeration Push reality further for impact. Bigger expressions, more dynamic poses. Animation isn't reality - it's reality enhanced.
11. Solid Drawing Three-dimensional thinking. Weight, balance, anatomy. Even 2D characters should feel like they have volume.
12. Appeal Charisma in design. Characters should be interesting to watch. Clear shapes, good proportions, distinctive features.

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 - Quick Start is a skill published in the GitHub repository dylantarre/animation-principles (79 stars, last pushed 8mo ago), licensed MIT. It adds 24 tokens to every session and 529 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.
