MiniMax Skills is a collection of development skills, APIs, and configuration formats for AI coding agents. Developers use it to get structured guidance for frontend, backend, Android, iOS, and shader work across several technology stacks. Catalogue entries package its skills, agents, and plugins for use with coding assistants.
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 | $0.00083 | $0.01178 |
| Opus 5.5 | $0.00033 | $0.00471 |
| Sonnet 5.5 | $0.00017 | $0.00236 |
| Haiku 4.5 | $0.00008 | $0.00118 |
Grade A, and why
flutter-dev 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 2mo 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.

Flutter Development Guide
A practical guide for building cross-platform applications with Flutter 3 and Dart. Focuses on proven patterns, state management, and performance optimization.
Quick Reference
Widget Patterns
| Purpose | Component |
|---|---|
| State management (simple) | StateProvider + ConsumerWidget |
| State management (complex) | NotifierProvider / Bloc |
| Async data | FutureProvider / AsyncNotifierProvider |
| Real-time streams | StreamProvider |
| Navigation | GoRouter + context.go/push |
| Responsive layout | LayoutBuilder + breakpoints |
| List display | ListView.builder |
| Complex scrolling | CustomScrollView + Slivers |
| Hooks | HookWidget + useState/useEffect |
| Forms | Form + TextFormField + validation |
Performance Patterns
| Purpose | Solution |
|---|---|
| Prevent rebuilds | const constructors |
| Selective updates | ref.watch(provider.select(...)) |
| Isolate repaints | RepaintBoundary |
| Lazy lists | ListView.builder |
| Heavy computation | compute() isolate |
| Image caching | cached_network_image |
Core Principles
Widget Optimization
- Use
constconstructors wherever possible - Extract static widgets to separate const classes
- Use
Keyfor list items (ValueKey, ObjectKey) - Prefer
ConsumerWidgetoverStatefulWidgetfor state
State Management
- Riverpod for dependency injection and simple state
- Bloc/Cubit for event-driven workflows and complex logic
- Never mutate state directly (create new instances)
- Use
select()to minimize rebuilds
Layout
- 8pt spacing increments (8, 16, 24, 32, 48)
- Responsive breakpoints: mobile (<650), tablet (650-1100), desktop (>1100)
- Support all screen sizes with flexible layouts
- Follow Material 3 / Cupertino design guidelines
Performance
- Profile with DevTools before optimizing
- Target <16ms frame time for 60fps
- Use
RepaintBoundaryfor complex animations - Offload heavy work with
compute()

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-dev is a skill published in the GitHub repository MiniMax-AI/skills (13,743 stars, last pushed 6mo ago), licensed MIT. It adds 83 tokens to every session and 1,178 once invoked, about $0.0003 per session on Opus 5.5. 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.
