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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00020 | $0.00749 |
| Opus 5 | $0.00010 | $0.00375 |
| Sonnet 5 | $0.00004 | $0.00150 |
| Haiku 4.5 | $0.00002 | $0.00075 |
Grade A, and why
timing-calibration 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.

Timing Calibration
Get animation speed right using Disney's timing principles.
Problem Indicators
- "Too slow" or "too fast" feedback
- Animations feel inconsistent
- Similar actions have different speeds
- Users wait for animations
- Motion feels robotic or unnatural
Diagnosis by Principle
Timing
Issue: Duration doesn't match action type Fix: Micro-interactions: 100-150ms. Transitions: 200-400ms. Complex reveals: 400-600ms. Never exceed 1s for UI.
Slow In and Slow Out
Issue: Linear timing feels mechanical Fix: Use easing. Ease-out for entrances (fast start, soft landing). Ease-in for exits (soft start, quick finish).
Arcs
Issue: Straight-line motion at wrong speed Fix: Curved paths need more time than straight paths. Increase duration for arc motion.
Staging
Issue: Multiple speeds compete Fix: Similar elements should animate at similar speeds. Create timing harmony.
Secondary Action
Issue: Secondary animations at wrong relative speed Fix: Secondary actions should be slightly slower than primary. Creates natural hierarchy.
Timing Scale
| Category | Duration | Use For |
|---|---|---|
| Instant | 0-100ms | Hover states, micro-feedback |
| Fast | 100-200ms | Buttons, toggles, small elements |
| Normal | 200-300ms | Cards, modals, most transitions |
| Slow | 300-400ms | Page transitions, large elements |
| Deliberate | 400-600ms | Complex reveals, onboarding |
Quick Fixes
- Start with 200ms - Adjust from there
- Larger elements = longer duration - Size affects perceived speed
- Distance affects timing - Longer travel = longer duration
- Create a timing scale - Use 3-4 consistent values
- Test at 2x speed - If too slow works, use it
Troubleshooting Checklist
- Is duration under 400ms for most UI?
- Do similar elements have similar timing?
- Is easing applied (not linear)?
- Does larger movement have longer duration?
- Test: Speed up by 30%—still readable?
- Test: Slow down by 30%—feels sluggish?
- Are users waiting for animations?
- Compare to platform conventions (iOS/Android/Web)
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.

timing-calibration is a skill published in the GitHub repository dylantarre/animation-principles (81 stars, last pushed 8mo ago), licensed MIT. It adds 20 tokens to every session and 749 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 2026-09-03.
