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 | $0.00626 |
| Opus 5 | $0.00012 | $0.00313 |
| Sonnet 5 | $0.00005 | $0.00125 |
| Haiku 4.5 | $0.00002 | $0.00063 |
Grade A, and why
Animation Principles - Novice 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Building Your Animation Foundation
You know the basics. Now let's understand how to actually use these 12 principles in your work.
1. Squash and Stretch
What it does: Gives weight and flexibility to objects. Try this: Animate a bouncing ball. Squash it 20-30% on impact, stretch it slightly at peak velocity.
2. Anticipation
What it does: Prepares the viewer for action. Try this: Before a character jumps, have them bend their knees. The bigger the anticipation, the bigger the expected action.
3. Staging
What it does: Directs attention clearly. Try this: Use silhouettes to test your poses. If you can't tell what's happening in shadow, restage it.
4. Straight Ahead vs Pose to Pose
What it does: Two animation methods with different results. Try this: Use pose-to-pose for planned actions (walks, dialogue). Use straight ahead for wild, organic motion (fire, water).
5. Follow Through and Overlapping Action
What it does: Creates natural, fluid movement. Try this: After your character stops, let hair, clothes, and appendages continue moving for a few frames.
6. Slow In and Slow Out
What it does: Adds weight and smoothness. Try this: Add extra frames at the start and end of movements. Fewer frames in the middle means faster motion.
7. Arc
What it does: Makes movement feel natural. Try this: Track your character's hand through a wave. It should draw a smooth curve, not zigzag.
8. Secondary Action
What it does: Adds richness without distraction. Try this: A sad character might wipe their eye while talking. It supports the emotion without stealing focus.
9. Timing
What it does: Controls the mood and physics. Try this: Same action, different frame counts. 4 frames = snappy/light. 12 frames = heavy/deliberate.
10. Exaggeration
What it does: Pushes reality for effect. Try this: Find the real movement, then push it 20% further. Scared? Eyes wider. Angry? Lean more forward.
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 - Novice is a skill published in the GitHub repository dylantarre/animation-principles (80 stars, last pushed 8mo ago), licensed MIT. It adds 24 tokens to every session and 626 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.
