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 | $0.00091 | $0.02258 |
| Opus 5 | $0.00046 | $0.01129 |
| Sonnet 5 | $0.00018 | $0.00452 |
| Haiku 4.5 | $0.00009 | $0.00226 |
Grade A, and why
diagram-animation 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 12d 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.

Diagram & Data Animation
Make structure and data legible by revealing it over time — one idea per beat. Build progressive node/edge reveals, flowing connectors, and animated charts (bars grow, lines draw, numbers count up) for web or video.
When to use
- Architecture, flow, or sequence diagrams that build step by step.
- Animated charts: bars grow, lines draw on, numbers count up.
- "How it works" walkthroughs and process explainers.
- Showing data or signal flowing along connectors.
Core principle: progressive disclosure
Never show everything at once. Reveal in this order: nodes → edges → labels. Highlight the active element and dim the rest (focus + context). Pace to comprehension, not flash — hold each step 0.5–1.5s so it lands. Keep a consistent visual grammar: color means meaning, and that mapping never changes mid-piece.
Quick reference
| Goal | Mechanism | Easing |
|---|---|---|
| Node appear | scale 0.8→1 + opacity, transform-origin:center |
back.out(1.5) / easeOut |
| Edge connect | stroke-dashoffset len→0 |
easeInOut, 0.4–0.7s |
| Flowing data | animate stroke-dashoffset looping + traveling dot |
linear, infinite |
| Bar grow | scaleY 0→1, transform-origin:bottom |
easeOut, stagger 0.06s |
| Line chart | path stroke-dashoffset len→0 |
easeInOut, 0.8–1.2s |
| Count-up | interpolate value with eased t |
easeOutCubic |
| Highlight | active full-opacity, others opacity:.35 |

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

diagram-animation is a skill published in the GitHub repository iart-ai/explainer-video-skills (20 stars, last pushed 2mo ago), licensed MIT. It adds 91 tokens to every session and 2,258 once invoked, about $0.0005 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.
