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 | $0.00022 | $0.00650 |
| Opus 5 | $0.00011 | $0.00325 |
| Sonnet 5 | $0.00004 | $0.00130 |
| Haiku 4.5 | $0.00002 | $0.00065 |
Grade A, and why
trust-reliability 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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Trust & Reliability Animation
Create animations that establish confidence, consistency, and dependable user experiences.
Emotional Goal
Trust develops through predictable, controlled movements that respect user expectations. Reliability means animations behave consistently and never surprise negatively.
Disney Principles for Trust
Squash & Stretch
Minimal stretch (5-10% maximum). Controlled deformation shows stability. Elements should feel solid and grounded, not rubbery.
Anticipation
Subtle but present (50-100ms). Brief preparation signals what's coming without surprises. Users should always know what to expect next.
Staging
Clear, unambiguous presentation. One action at a time. Important elements are obvious. No hidden or confusing movements.
Straight Ahead Action
Avoid for trust-building. Prefer pose-to-pose for predictable, controlled results. Every frame should be intentional.
Follow Through & Overlapping Action
Restrained follow-through. Elements settle quickly without excessive bouncing. Professional, controlled completion of movements.
Slow In & Slow Out
Smooth, symmetrical easing. ease-in-out creates predictable, professional motion. No sudden accelerations or jarring stops.
Arc
Gentle, predictable curves. Consistent arc patterns across similar interactions. Avoid erratic or unexpected paths.
Secondary Action
Minimal and purposeful. Supporting animations should reinforce, not distract. Loading indicators should be calm and steady.
Timing
Moderate, consistent timing (250-400ms). Never too fast (feels rushed) or too slow (feels broken). Same elements should always animate at same speed.
Exaggeration
Very minimal (5-10%). Near-realistic movements feel professional and trustworthy. Subtle refinement over dramatic effect.
Solid Drawing
Maintain perfect proportions. No warping or distortion. Elements should feel stable and well-constructed.
Appeal
Clean, balanced designs. Symmetry suggests stability. Professional aesthetics over playful charm.
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.
- 7d ago First seen · 86 lines · 22 tokens per session scan A 0164d29b747b
trust-reliability is a skill published in the GitHub repository dylantarre/animation-principles (80 stars, last pushed 8mo ago), licensed MIT. It adds 22 tokens to every session and 650 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.
