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 | $0.00021 | $0.00766 |
| Opus 5 | $0.00010 | $0.00383 |
| Sonnet 5 | $0.00004 | $0.00153 |
| Haiku 4.5 | $0.00002 | $0.00077 |
Grade A, and why
comfort-safety 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 7d 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.

The opening of the file, as written. The whole thing — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Comfort & Safety Animation
Create animations that reassure, protect, and make users feel secure.
Emotional Goal
Comfort comes from predictable, gentle motion that never startles. Safety means animations that communicate protection, stability, and user control.
Disney Principles for Comfort
Squash & Stretch
Minimal, soft (5-10%). Gentle give without instability. Like a cushion—absorbs impact, maintains structure.
Anticipation
Clear, reassuring preparation (150-200ms). Users always know what's coming. No surprises, no hidden actions.
Staging
Enclosed, protected compositions. Clear boundaries. Safe spaces. Visual hierarchy that guides without overwhelming.
Straight Ahead Action
Avoid. Safety requires predictability. Every movement should be controlled and expected.
Follow Through & Overlapping Action
Gentle, cushioned settling. Soft landings. Elements ease into place like being tucked in.
Slow In & Slow Out
Smooth, gentle curves throughout. No sudden changes. ease-in-out for predictable, comfortable motion.
Arc
Soft, natural curves. Cradling, embracing paths. Motion that wraps around rather than cuts through.
Secondary Action
Reassuring cues only. Checkmarks, shields, locks. Visual confirmation of safety and completion.
Timing
Moderate, unhurried (300-450ms). Time to process and feel safe. Never rushed or abrupt.
Exaggeration
None to minimal. Realistic, grounded movements. Comfort requires believability.
Solid Drawing
Stable, balanced forms. Low center of gravity. Shapes that feel grounded and secure.
Appeal
Warm, muted colors. Soft edges. Familiar, comfortable aesthetics. Nothing aggressive or sharp.
Timing Recommendations
| Element | Duration | Easing |
|---|---|---|
| Transitions | 300-400ms | ease-in-out |
| Feedback | 200-250ms | ease-out |
| Confirmation | 350-450ms | ease-out |
| Protection reveal | 400-500ms | ease-in-out |

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.

comfort-safety is a skill published in the GitHub repository dylantarre/animation-principles (80 stars, last pushed 8mo ago), licensed MIT. It adds 21 tokens to every session and 766 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.
