timing-mastery

timing-mastery is a skill for Claude Code, Codex from dylantarre/animation-principles. It costs 37 tokens per session (725 once invoked), scanned A, original, MIT.

A guide to choosing how long movements, pauses, and transitions should last. In animation, timing changes how an action feels: fast can feel urgent or comic, while slow can feel heavy or dramatic.

In plain words
What is it for?
Use it to set animation durations, pace action sequences, shape dramatic pauses, create comedic beats, and coordinate the timing of main and secondary movements.
Why use it?
It helps prevent motion from feeling rushed, dull, or rhythmically inconsistent.

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

timing-mastery 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 1mo 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.

Timing Mastery

Think like a drummer. Animation is rhythm made visible. The space between beats matters as much as the beats themselves.

Core Mental Model

Before animating anything, ask: How many frames does this deserve?

Timing is the soul of animation. The same motion at different speeds tells completely different stories. Fast = light, urgent, comedic. Slow = heavy, dramatic, thoughtful.

The 12 Principles Through Timing

Timing — The principle itself. Count frames obsessively. A 6-frame action feels snappy. A 24-frame action feels deliberate. Know the vocabulary of duration.

Slow In & Slow Out — Time is elastic at the edges. Actions ease into existence and settle out of motion. The middles can be fast, but beginnings and endings need breath.

Anticipation — Timing creates suspense. Hold the anticipation longer than feels comfortable. The audience's tension builds in the pause before release.

Follow Through & Overlapping Action — Stagger your timing. Not everything arrives at once. Lead with the main action, let secondary elements catch up on their own schedules.

Secondary Action — Time secondary elements to complement, not compete. They should land slightly after the primary beat, like harmony following melody.

Staging — Give the audience time to read. Fast cutting confuses. Hold important poses long enough for comprehension. Clarity requires duration.

Exaggeration — Timing amplifies exaggeration. A long anticipation followed by instant action creates snap. Stretch time to stretch impact.

Squash & Stretch — Speed determines deformation. Fast motion = more stretch. Impact = instant squash. The timing of shape change sells velocity.

Arcs — Speed varies along the arc. Fastest at the bottom of a swing, slowest at the apex. Timing follows the physics of pendulums.

Appeal — Rhythmic motion is appealing. Characters with good timing feel alive. Arrhythmic timing creates unease (useful for villains or horror).

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.
