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 | $0.00623 |
| Opus 5 | $0.00015 | $0.00311 |
| Sonnet 5 | $0.00006 | $0.00125 |
| Haiku 4.5 | $0.00003 | $0.00062 |
Grade A, and why
Animation Principles - Advanced 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 — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Nuanced Application of Animation Principles
You've internalized the fundamentals. Now explore the subtleties that separate competent from exceptional animation.
Beyond the Basics
Squash and Stretch: The Invisible Application
Facial animation relies on subtle squash/stretch most viewers never consciously see. Brows compress, cheeks stretch, jaw volumes shift. The principle applies to rigid objects too - camera shake and motion blur are perceptual squash/stretch.
Anticipation: When to Subvert It
Lack of anticipation creates surprise, shock, comedy. A punch without wind-up reads as unexpected. Master animators use anticipation's absence as deliberately as its presence.
Staging: Negative Space as Tool
What you don't show matters. Empty frame space creates tension. Cramped staging creates claustrophobia. Staging includes compositional psychology, not just visibility.
Method Selection: Scene-Dependent Choices
Straight ahead for emotional spontaneity in performance. Pose-to-pose for precision timing in action. The choice shapes the final energy. Some scenes demand switching methods mid-shot.
Follow Through: Emotional Resonance
Heavy follow through suggests reluctance, weight, sadness. Minimal follow through suggests alertness, tension. The technical principle carries emotional subtext.
Slow In/Out: Non-Linear Easing
Beyond basic ease curves: snap with overshoot, settle with micro-bounces, hold with drift. Custom spacing graphs for specific emotional beats.
Arcs: Broken Arcs as Choice
Robotic characters, sudden decisions, physical impacts - these break arcs intentionally. The principle teaches natural motion so you can meaningfully deviate.
Secondary Action: Counterpoint
Advanced secondary action can contrast the primary emotion. Happy walk with nervous hand-wringing hints at hidden anxiety. Layers create complexity.
Timing: Frame-by-Frame Psychology
Single frame holds create different impact than two-frame holds. The difference between 8 and 10 frames changes weight perception. Frame-level sensitivity matters.
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 - Advanced 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 623 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.
