Purpose

This skill handles root SE architecture tasks, including system design, creating Architecture Decision Records (ADRs), performing trade-off analyses, and selecting tech stacks. It integrates with OpenClaw's core engine to output structured artifacts like diagrams, documents, or JSON reports.

When to Use

Use this skill when starting a new system design, evaluating architectural decisions, or resolving trade-offs in tech choices. Apply it during project kickoffs, refactoring, or when scaling systems, especially for complex applications involving microservices, cloud infrastructure, or distributed systems.

Key Capabilities

• Generate ADRs in Markdown format with sections for context, decision, and consequences.
• Analyze trade-offs using predefined models (e.g., CAP theorem for distributed systems).
• Recommend tech stacks based on inputs like requirements, constraints, and performance metrics.
• Produce system design diagrams via integration with tools like PlantUML.
• Support iterative refinement of designs through feedback loops.

Usage Patterns

Invoke the skill via OpenClaw CLI or API for interactive or scripted workflows. Start with a command to initialize a design session, then chain subcommands for analysis. For example, pipe outputs to other tools for visualization. Always provide inputs as JSON files for consistency. Use environment variables for authentication, like $OPENCLAW_API_KEY, to secure requests.
