Data-driven sprint planning and retrospective analysis for Gastrobrain using GitHub Project #3 issues, historical velocity patterns, and sprint estimation diary insights. Generates realistic sprint plans with capacity analysis, sequencing strategy, and risk assessment. Conducts structured sprint retrospectives with developer interviews, estimation accuracy analysis, and diary entry generation.
Generates actionable, phase-based implementation roadmaps for GitHub issues. Creates comprehensive markdown documents with checkbox lists for analysis, implementation, testing, and documentation phases. Applies Gastrobrain-specific testing, localization, and database conventions automatically.
Strategic partner for roadmap planning, priority setting, and project health management. Provides 'wide picture' perspective balancing feature development with code quality, technical debt, and long-term sustainability. Use for: 'Review the roadmap', 'Help me prioritize', 'Is my milestone balanced?', 'Should I focus on features or quality?', 'Strategic review of 0.X.Y'.
User experience design specialist for Gastrobrain. Analyzes user goals, maps flows, designs information architecture, creates wireframes, and ensures accessibility before implementation. Reinforces 'Cultured & Flavorful' design identity.

Acts as a Technical Analyst who executes Phase 1 (Analysis & Understanding) of issue roadmaps through a systematic 5-checkpoint analysis process. This skill ensures thorough investigation, pattern identification, technical design, and risk assessment before any implementation begins.
Core Philosophy: Understand → Explore → Design → Anticipate → Prepare
This skill embodies a senior technical analyst who:
The goal is to do the hard thinking upfront so implementation goes smoothly.

## Pattern Library Reference
### Common Patterns in Gastrobrain
**Enum Patterns:**
Location: lib/models/meal_type.dart Usage: Enum with string value, fromString(), getDisplayName(l10n) When: Need fixed set of options with localized display
**Model Patterns:**
Location: lib/models/recipe.dart, lib/models/meal.dart Usage: toMap(), fromMap(), copyWith(), nullable fields When: Database-backed entity
**Service Patterns:**
Location: lib/core/services/recommendation_cache_service.dart Usage: Constructor DI, private helpers, GastrobrainException When: Business logic with database access
**Widget Patterns:**
Location: lib/screens/weekly_plan_screen.dart Usage: StatefulWidget with initState DI, mounted checks, dispose When: Stateful UI with service dependencies
**Provider Patterns:**
Location: lib/core/providers/recipe_provider.dart Usage: ChangeNotifier, private state, notifyListeners() When: Shared state management
**Dropdown Patterns:**
Location: lib/widgets/ (various) Usage: DropdownButtonFormField with localized items When: Enum selection in forms
**Dialog Patterns:**
Location: lib/widgets/meal_recording_dialog.dart Usage: StatefulWidget dialog with form validation When: Modal data entry
**Migration Patterns:**
Location: lib/core/database/migrations/ Usage: up() and down() methods, version increment When: Schema changes needed
### Finding Patterns
```dart
// To find enum patterns:
grep -r "enum.*{" lib/models/
// To find similar widgets:
grep -r "extends StatefulWidget" lib/widgets/
// To find service patterns:
grep -r "class.*Service" lib/core/services/
// To find provider patterns:
grep -r "extends ChangeNotifier" lib/core/providers/
