Animation Principles - Intermediate

Animation Principles - Intermediate is a skill for Claude Code, Codex from dylantarre/animation-principles. It costs 25 tokens per session (555 once invoked), scanned A, original, MIT.

An intermediate guide to combining animation principles so that timing, motion, composition, and secondary actions support one another.

In plain words
What is it for?
Use it to plan more complex animations, balance anticipation with follow-through, coordinate staging with secondary action, and apply easing along motion arcs.
Why use it?
It explains how individual techniques interact and highlights common mistakes when combining them.

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.

Security

Grade A, and why

Animation Principles - Intermediate 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 5d 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.

Combining Principles for Stronger Animation

You can apply individual principles. Now learn to weave them together and understand their interdependencies.

Principle Synergies

Squash/Stretch + Timing

Volume preservation is key. Faster motion = more stretch. The timing dictates the degree. A 2-frame anticipation needs less squash than a 6-frame one.

Anticipation + Follow Through

These are mirrors. Anticipation magnitude should roughly match follow through. Big wind-up = big settle. They create rhythmic bookends to any action.

Staging + Secondary Action

Secondary actions must support staging, never compete. If staging says "look at the face," secondary action in hands should point attention there, not away.

Arcs + Slow In/Out

Arcs aren't uniform speeds. Apply easing along the arc path. Spacing should bunch at start/end of the arc, spread in the middle.

Pose to Pose + Straight Ahead

Hybrid approach: Key poses first (pose-to-pose), then animate overlapping elements straight ahead. Best of both: structure with spontaneity.

Common Combination Mistakes

Over-anticipation: When every action has massive wind-up, nothing feels spontaneous. Reserve big anticipation for big payoffs.

Competing secondary actions: Three things moving differently splits attention. Hierarchy matters - one leads, others support.

Uniform timing: Every action at 12 frames feels mechanical. Vary your timing: quick decisions, slow realizations.

Arc neglect in follow through: The main action arcs beautifully, then appendages move linearly. Everything arcs.

The 12 Principles by Function

Physics: Squash/Stretch, Timing, Arcs, Slow In/Out Clarity: Staging, Solid Drawing, Anticipation Interest: Secondary Action, Exaggeration, Appeal Technique: Straight Ahead/Pose to Pose, Follow Through/Overlap

Integration Exercise

Animate a character sitting down:

  1. Staging: Camera angle shows full body profile
  2. Anticipation: Slight upward before descent
  3. Arcs: Hips trace a curved path down
  4. Timing: Faster drop, slower settle
  5. Squash: Compress on contact
  6. Follow Through: Arms/head continue after hips land
  7. Overlapping: Hair settles last
  8. Secondary: Adjusting clothing
  9. Slow Out: Gradual stop to final pose

Animation Principles - Intermediate is a skill published in the GitHub repository dylantarre/animation-principles (79 stars, last pushed 8mo ago), licensed MIT. It adds 25 tokens to every session and 555 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.
