animation

animation is a skill for Claude Code from MonumentalSystems/Atlas-Agent-Teams. It costs 15 tokens per session (1,473 once invoked), scanned A, original, MIT.

Reference material for making 3D objects move convincingly. It covers timing, keyframes, poses, weight, anticipation, and other principles that make actions clear and natural.

In plain words
What is it for?
Planning character and object animations, shaping motion with keyframes, improving readability, and applying established animation principles.
Why use it?
It helps animators avoid stiff or confusing movement by giving structure to posing, timing, and transitions. It also describes workflows such as blocking, breakdowns, and filling in intermediate frames.

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 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.

Animation Principles

The 12 Principles of Animation

  • Squash and Stretch: Convey weight, flexibility, and impact
  • Anticipation: Prepare audience for upcoming actions
  • Staging: Present action clearly and unmistakably
  • Straight Ahead vs Pose to Pose: Different animation workflows
  • Follow-Through and Overlapping Action: Natural movement flow
  • Slow In and Slow Out: Natural acceleration and deceleration
  • Arcs: Natural curved paths of motion
  • Secondary Action: Reinforce primary action with complementary movements
  • Timing: Number of frames for action
  • Exaggeration: Enhance actions for clarity and appeal
  • Solid Drawing: 3D form and weight
  • Appeal: Engaging and memorable characters

Additional Principles

  • Weight: Convey mass and gravity
  • Balance: Maintain equilibrium
  • Rhythm: Create pleasing patterns of movement
  • Personality: Infuse character into movement
  • Readability: Ensure actions are clear and understandable

Keyframe Animation Techniques

Keyframing Workflow

  • Blocking: Establish key poses that define the action
  • Breakdowns: Add intermediate poses to define timing
  • In-Betweening: Fill in frames between keys
  • Polishing: Refine curves and add secondary motion
  • Review: Check animation from multiple angles

Key Types

  • Pose Keys: Define the main poses of an action
  • Timing Keys: Define the timing and spacing
  • Breakdown Keys: Define the transition between poses
  • In-Between Keys: Fill in the motion between breakdowns

Keyframe Spacing

  • Linear: Constant speed
  • Ease In: Slow start, accelerates
  • Ease Out: Fast start, decelerates
  • Ease In Out: Slow start and end, fast middle
  • Custom: Custom spacing for specific effects

Procedural Animation

Procedural Techniques

  • Physics-Based: Use physics simulation for realistic movement
  • Inverse Kinematics: Calculate joint positions from end effector
  • Forward Kinematics: Calculate end effector from joint positions
  • Constraint-Based: Use constraints to drive animation
  • Mathematical Functions: Use sine waves, noise, etc.

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 is a skill published in the GitHub repository MonumentalSystems/Atlas-Agent-Teams (21 stars, last pushed 29d ago), licensed MIT. It adds 15 tokens to every session and 1,473 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.
