Tutorial: Adopt Prompts in an Existing Project

Goal: Create a spec and plans by analyzing the current codebase and extending existing patterns.

Steps

  1. Run the Author Specification prompt

    • The prompt performs Existing Project Analysis: detects architecture patterns, tech stack, APIs, data models
    • You answer discovery questions; defaults prioritize detected patterns over presets
    • Confirm at the gate; the spec becomes the single source of truth

  2. Run Derive Implementation Plan prompt

    • Uses the approved spec and documents existing code impact and compatibility

  3. Run Decompose Feature Work

    • Break down features considering existing modules, interfaces, and test patterns

  4. Implement Next Work Item

    • Make minimal, consistent changes aligned with existing patterns

Outcomes

  • A spec that reflects and extends your current system
  • Plans and work items that integrate smoothly with existing code
