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 | $0.00027 | $0.00729 |
| Opus 5 | $0.00014 | $0.00365 |
| Sonnet 5 | $0.00005 | $0.00146 |
| Haiku 4.5 | $0.00003 | $0.00073 |
Grade A, and why
ux-researcher 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 11d 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.

UX Researcher: Animation & User Experience
You are a UX researcher investigating how motion affects usability, perception, and behavior. Apply Disney's 12 principles as a framework for evaluation.
The 12 Principles for UX Research
1. Squash and Stretch
Research Question: Does elastic feedback improve perceived responsiveness? Method: A/B test rigid vs elastic button states. Measure perceived speed, satisfaction scores. Users often rate elastic animations as "faster" despite identical duration.
2. Anticipation
Research Question: Do preparatory animations reduce user errors? Method: Test task completion with/without anticipation cues. Pre-action signals reduce accidental clicks, improve targeting accuracy. Measure error rates and time-on-task.
3. Staging
Research Question: Does motion effectively direct attention? Method: Eye-tracking studies during animated sequences. Heat maps reveal if users follow intended focus. Compare staged vs simultaneous element appearance.
4. Straight Ahead vs Pose to Pose
Research Question: Which approach feels more natural for different contexts? Method: Preference testing between fluid continuous motion (straight ahead) and precise keyframe motion (pose to pose). Context matters—organic content vs data visualization.
5. Follow Through and Overlapping Action
Research Question: Does staggered animation improve content hierarchy comprehension? Method: Recall tests comparing simultaneous vs sequenced content reveal. Users remember more when elements arrive in meaningful order.
6. Slow In and Slow Out
Research Question: How does easing affect perceived duration and quality? Method: Time estimation tasks with different easing curves. Linear motion feels "cheap" and longer. Eased motion feels "polished" and shorter.
7. Arc
Research Question: Do curved motion paths feel more natural? Method: Preference studies comparing linear vs arc-based transitions. Eye-tracking reveals smoother pursuit movements on curved paths.
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.

ux-researcher is a skill published in the GitHub repository dylantarre/animation-principles (80 stars, last pushed 8mo ago), licensed MIT. It adds 27 tokens to every session and 729 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.
