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 | $0.00029 | $0.00557 |
| Opus 5 | $0.00015 | $0.00279 |
| Sonnet 5 | $0.00006 | $0.00111 |
| Haiku 4.5 | $0.00003 | $0.00056 |
Grade A, and why
Animation Principles - Expert 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.
How it starts
The opening of the file, as written. The whole thing — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Transcending the Principles
Mastery means knowing when to break rules. The principles are training wheels for intuition. Here's how experts leverage, subvert, and transcend them.
Intentional Violations
Anti-Squash/Stretch
Rigid motion creates uncanny, mechanical, or ethereal qualities. Spirited Away's gods move without squash - otherworldly presence. Perfect volume preservation can feel more alien than violations.
Omitted Anticipation
Into the Spider-Verse removes anticipation for snap cuts that feel like comic panels. Absence of anticipation = visual punctuation. Anticipation's removal is a choice, not an error.
Anti-Staging
David Lynch deliberately obscures important elements. Burying the point creates unease, mystery, viewer work. Strategic confusion can be the goal.
Pure Methods
Some masters work exclusively straight ahead (James Baxter's creature animation) or purely pose-to-pose (limited animation's stylized precision). Constraint breeds innovation.
Stopped Follow Through
Freezing follow through mid-motion creates held tension. Anime uses this for impact frames. The principle's interruption is the effect.
Linear Timing
Removing ease creates robotic precision or dreamlike float. Linear spacing isn't wrong - it's a vocabulary choice for specific effects.
Broken Arcs
Jerky, angular paths for insects, robots, or psychological breaks. Spider-Man: Into the Spider-Verse uses broken arcs for Miles vs. smooth arcs for Peter.
Conflicting Secondary Action
Body language contradicting primary action reveals character complexity. Smiling while clenching fists. Agreement words with disagreement gestures.
Wrong Timing
Comedy often uses "incorrect" timing. Delayed reactions, impossibly fast actions, freeze frames - timing violations for comic effect.
Reduced Exaggeration
Hyperrealism in animation (rotoscope, mo-cap) deliberately minimizes exaggeration. The uncanny valley is sometimes the destination.
Flat Drawing
UPA style, Samurai Jack - intentional flatness as graphic design. Solid drawing exists so you can meaningfully reject dimension.
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 - Expert is a skill published in the GitHub repository dylantarre/animation-principles (80 stars, last pushed 8mo ago), licensed MIT. It adds 29 tokens to every session and 557 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.
