Animation Principles - Troubleshooting

Animation Principles - Troubleshooting is a skill for Claude Code, Codex from dylantarre/animation-principles. It costs 25 tokens per session (654 once invoked), scanned A, original, MIT.

A symptom-based guide for finding problems in animation. It links feelings such as weightlessness, stiffness, unclear action, or lifelessness to principles that may need adjustment.

In plain words
What is it for?
Use it to troubleshoot timing, curved motion, anticipation, overlap, secondary movement, staging, and the sense of weight or clarity in an animation.
Why use it?
It helps developers and animators diagnose why movement feels wrong instead of changing timing or effects at random.

Token cost

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 - Troubleshooting 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.

Animation Troubleshooting Guide

Something's off. Use this to find and fix it.

Symptom-Based Diagnosis

"It feels floaty/weightless"

Check:

  • Slow in/out - Is spacing too even? Add bunching at start/end
  • Timing - Need more frames for weight? Fewer for snap?
  • Squash/stretch - Impact reaction visible?
  • Follow through - Settling properly or just stopping?

Fix: Add 2-4 frames to settle. Increase spacing variation. Add impact squash.

"It feels stiff/robotic"

Check:

  • Arcs - Are paths too straight?
  • Overlap - Is everything moving at once?
  • Secondary action - Is it present?
  • Anticipation - Too uniform?

Fix: Offset timing between body parts. Curve your motion paths. Vary anticipation amounts.

"I can't tell what's happening"

Check:

  • Staging - Silhouette clear?
  • Anticipation - Is viewer prepared for action?
  • Timing - Too fast to read?
  • Exaggeration - Key poses pushed enough?

Fix: Simplify composition. Add anticipation frames. Extend key poses. Push silhouette.

"It feels dead/lifeless"

Check:

  • Secondary action - Present and supporting?
  • Overlap - Different parts moving differently?
  • Timing - Varied or monotonous?
  • Appeal - Character design working?

Fix: Layer in secondary actions. Offset everything by 1-3 frames. Vary timing between actions.

"It feels cartoony when it should be subtle" (or vice versa)

Check:

  • Exaggeration - Calibrated to style?
  • Squash/stretch - Amount appropriate?
  • Timing - Snappy vs. naturalistic?
  • Anticipation - Size matches style?

Fix: Dial exaggeration to match reference. Adjust squash/stretch ratios. Match timing to style guide.

"Something feels wrong but I can't identify it"

Check:

  • Arcs - Track every moving part. Find the broken curve.
  • Volume - Is squash/stretch preserving mass?
  • Twins - Are poses too symmetrical?
  • Spacing - Graph your drawings. Find the anomaly.

Fix: Often it's one broken arc or inconsistent spacing. Track paths obsessively.
