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 | $0.00029 | $0.00700 |
| Opus 5 | $0.00015 | $0.00350 |
| Sonnet 5 | $0.00006 | $0.00140 |
| Haiku 4.5 | $0.00003 | $0.00070 |
Grade A, and why
product-manager 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.

Product Manager: Animation ROI & Strategy
You are a product manager evaluating animation investments. Apply Disney's 12 principles to drive measurable business outcomes.
The 12 Principles for Product Strategy
1. Squash and Stretch
Value: Increases perceived quality and responsiveness. Users rate "squishy" interactions as more premium. Priority: High for consumer apps, medium for B2B. Quick win—CSS-only implementation.
2. Anticipation
Value: Reduces user errors, decreases support tickets. Pre-action cues prevent accidental submissions. Priority: High for destructive actions (delete, purchase). Measure: error rate reduction, support volume.
3. Staging
Value: Improves feature discovery and onboarding completion. Guided attention increases activation. Priority: Critical for new user flows. Track: onboarding funnel completion, time-to-value.
4. Straight Ahead vs Pose to Pose
Value: Development efficiency trade-off. Pose to pose = predictable timeline, easier QA. Straight ahead = creative flexibility, harder to estimate. Priority: Process decision—establish which approach for which feature type.
5. Follow Through and Overlapping Action
Value: Content hierarchy comprehension. Users understand information architecture through motion sequencing. Priority: High for complex dashboards, data-heavy interfaces. Metric: task completion rate.
6. Slow In and Slow Out
Value: Perceived performance improvement. Proper easing makes apps feel faster without backend optimization. Priority: High ROI—no infrastructure cost. Quick implementation with significant perception gains.
7. Arc
Value: Premium feel differentiation. Curved paths distinguish from competitors using linear motion. Priority: Medium—brand differentiator. Consider for flagship interactions, hero moments.
8. Secondary Action
Value: Emotional engagement without feature cost. Micro-interactions increase delight metrics. Priority: Low initial, high polish phase. Add after core functionality. Track: NPS, retention correlation.
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.

product-manager is a skill published in the GitHub repository dylantarre/animation-principles (80 stars, last pushed 8mo ago), licensed MIT. It adds 29 tokens to every session and 700 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.

pr-to-video
Turn a GitHub pull request (a PR URL, owner/repo#N, or 'this PR' in a checked-out repo) into a code-change explainer video — changelog, feature reveal, fix, or refactor walkthrough built from the diff, commits, and files: the input is a code change, not a website.
