Ark Architecture Skill
Design architecture for Ark features following existing patterns and principles.
Process
- Analyze Current Solution - Use the ark-analysis skill to examine relevant parts of the codebase
- Identify Patterns - Find existing idioms, data models, and service structures to reuse
- Design for Reuse - Extend existing components rather than creating new ones
- Enable Incremental Updates - Break changes into small, independent pieces
- Flag One-Way Decisions - Raise questions on choices that are hard to reverse
Principles
- Reuse over creation - Extend existing services, models, and patterns
- Follow existing idioms - Match current code style, naming, and structure
- Incremental delivery - Design so features can be shipped in stages
- Reversibility - Identify and question decisions that lock in future options
Conventions
- Watch endpoints: Use
?watch=truequery param for SSE streaming (Kubernetes-style) - Service ports: Use named ports (e.g.,
port: mcp) rather than port numbers
Output
Architecture documents should include:
- Component diagram showing how new pieces fit with existing ones
- Data model extending current schemas
- API design following existing conventions
- List of one-way decisions requiring team input
- Implementation phases for incremental delivery
