Tech Design Doc

What it does

This skill enables AI agents to generate comprehensive technical design documents for software projects. It structures complex architectural decisions into readable formats that align with industry standards.

When to use it

• Planning a new microservices architecture and needing a high-level overview of components and data flow.
• Documenting API specifications before development begins to ensure team alignment on endpoints and payloads.
• Creating database schema designs with clear explanations of relationships, constraints, and indexing strategies.
• Preparing migration plans for legacy system modernization by outlining step-by-step transition tactics.

Key capabilities

• Generates structured markdown documents containing sections like Overview, Architecture, Data Models, and API Specs.
• Adapts output to specific frameworks (e.g., React, Node.js) or cloud platforms (AWS, Azure).
• Includes diagrams descriptions or Mermaid syntax for visualizing system interactions.
• Tailors tone and depth based on audience, from executive summaries to developer-level implementation details.

Example prompts

• "Create a technical design doc for a real-time chat application using WebSockets and Redis."
• "Draft a design document for migrating our monolithic e-commerce site to a serverless architecture."
• "Write a detailed tech spec including database schema and API endpoints for a fintech payment gateway."

Tips & gotchas

Ensure you provide context about your target stack (e.g., Python/Django, Go/Gin) so the generated doc reflects appropriate patterns. The skill produces text-based documentation; while it can describe diagrams, actual image rendering may require external tools or plugins.
