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.

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 | $0.00048 | $0.00329 |
| Opus 5 | $0.00024 | $0.00164 |
| Sonnet 5 | $0.00010 | $0.00066 |
| Haiku 4.5 | $0.00005 | $0.00033 |
Grade A, and why
flutter-motion 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 8d 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.
What it actually says
Flutter Motion
Use motion to explain change, causality, continuity, hierarchy, or feedback. Remove motion that communicates none of these.
Specify
- Name the event, property change, user value, trigger, interruption behavior, and completion state.
- Select the least complex Flutter mechanism that satisfies it: implicit animation,
AnimatedSwitcher, explicit controller, hero transition, custom painter, or physics simulation. - Define duration ranges, curve character, sequencing, gesture relationship, and reduced-motion equivalent. Read
references/motion.md. For multi-domain state changes, readreferences/connected-product-workflows.mdand animate only the region whose state changed. - Check how the motion behaves during rapid taps, navigation interruption, rebuilds, route disposal, low frame budgets, and changed accessibility settings.
Implement
- Animate transform and opacity before layout-heavy properties when visually equivalent.
- Dispose controllers and avoid duplicated tickers.
- Preserve semantic state throughout transitions.
- Avoid delayed access to core actions.
- Keep list stagger subtle and bounded; never scale delay linearly across large collections.
- Provide immediate or cross-fade alternatives when reduced motion is requested.
Verify
Test at normal and reduced motion, under interruption, and on the lowest relevant performance tier. Inspect frame behavior when tooling permits. Report unmeasured performance instead of assuming smoothness.
What ships with it
3 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.

flutter-motion is a skill published in the GitHub repository musabekisakov-imj/flutter-design-engineer (4 stars, last pushed 1mo ago), licensed MIT. It adds 48 tokens to every session and 329 once invoked, about $0.0002 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 2026-08-31.

Best practices for Flutter animations using the built-in animation framework. Use when creating, modifying, or reviewing animations, transitions, motion, or animated widgets. Covers implicit animations, explicit animations, page transitions, and Material 3 motion tokens.
data-display-and-selection
Complex data deserves multiple view modes — grid, list, table — chosen by the user based on their task. Row and item selection should use large hit areas (the whole row or card, not just a checkbox). Selected state is communicated through a subtle background colour shift. Mass actions appear when items are selected.…
