About
Deep Plan is a specialized Claude Code skill designed to bridge the gap between high-level ideas and production-ready code. It orchestrates a rigorous multi-stage workflow—including automated codebase and web research, interactive stakeholder interviews, and cross-model validation using Gemini or OpenAI—to generate detailed, sectionized implementation plans. By integrating Test-Driven Development (TDD) principles and splitting complex features into manageable segments, it ensures your development phase is guided by a robust, peer-reviewed technical architecture that minimizes architectural debt.
