🏗️ Skill Architecture

All skills follow a modular, flat structure for maximum clarity and AI compatibility.

Directory Structure

└── <skill-name>/
    ├── SKILL.md        # Entry point: Goals, Process, Constraints
    └── references/     # Detailed implementation guides

Core Design Principles

1. Single Responsibility: Each skill focuses on one technology or framework
2. LLM-Optimized: Documents are structured for AI context windows with semantic headings
3. Production-Ready: Working code snippets, not placeholders
4. Version-Aware: All packages use latest stable versions (as of 2026-03-31)

🎯 Development Philosophy

"Simplicity is the ultimate sophistication."

• Minimalist Approach: Focus on user experience, not engineering abstractions
• Modern Best Practices: Latest stable releases with version documentation
• Type Safety: Leverage Dart 3+ features (pattern matching, records, sealed classes)
• Zero Placeholder Policy: All code snippets are production-ready

🚀 Recent Updates (2026-04-02)

fl-chart — Flutter Data Visualization (v1.2.0)

• ✅ 6 chart types: LineChart, BarChart, PieChart, ScatterChart, RadarChart, CandlestickChart
• ✅ Quick start examples for all chart types with production-ready code
• ✅ Common config patterns: titles/axes, grid, border, extra lines, touch interactivity, animations, pan/zoom
• ✅ Advanced patterns: stacked bars with per-layer tooltip, multi-series gradient lines, donut chart touch expansion, multi-dataset radar overlay, horizontal bar rotation
• ✅ 7 reference files: full API property tables for each chart type + shared base components

Previous Updates (2026-04-01)

Fleet Mode Quality Audit — All 36 Skills

• ✅ 36 SKILL.md files audited and standardized to Agent Skill Best Practices
• ✅ Gerund naming enforced (applying-*, managing-*, testing-*)
• ✅ Third-person descriptions with trigger keywords for precise AI activation
• ✅ 500-line limit enforced — flutter-bloc (594→147 lines) and flutter-riverpod (625→162 lines) split with new references/ files

Riverpod 3.0 Full Coverage

• ✅ Breaking changes: == equality for all state comparisons, fresh Notifier instances on rebuild (resource leak risk), FamilyNotifier removed, Ref generics removed
• ✅ Consumer vs ConsumerWidget: decision table; prefer Consumer + ref.watch().select() for surgical rebuilds
• ✅ New APIs: generic providers, @Dependencies scoping, AsyncValue sealed + progress, weak listeners, overrideWithBuild
• ✅ Mutations (experimental): tsx.get() pattern, exhaustive 4-state switch (Idle/Pending/Error/Success)
• ✅ Offline Persistence (experimental): riverpod_sqflite, persist() in build(), StorageOptions

effective-dart — Dart 3.7–3.10 Features

• ✅ Dot shorthands (3.10): .blue instead of Color.blue, .all(16) instead of EdgeInsets.all(16)
• ✅ Null-aware collection elements (3.8): [?nullable] auto-excludes nulls
• ✅ Wildcard variables (3.7): non-binding _, multiple _ in same scope
• ✅ New lints (3.9): switch_on_type, unnecessary_unawaited, @awaitNotRequired

openapi-to-dart — Reframed as Manual Implementation Guide

• ✅ Removed code-generation framing; now covers Dio client setup, Equatable vs Freezed decision table, Service/Repository layers, DioException → ApiError mapping
