Deep Plan is a specialized Claude Code skill that orchestrates a rigorous research, interview, and review process to create detailed, TDD-oriented implementation plans.

What are the technical requirements?

Deep Plan requires Python 3.11 or higher and the 'uv' package manager to run its underlying automation scripts and tools.

Can Deep Plan analyze my existing codebase?

Yes, its research protocol includes specific steps for codebase analysis, allowing the AI to understand your existing patterns and constraints before proposing a plan.

Do I need external API keys to use this skill?

While Deep Plan supports Gemini and OpenAI for external reviews, it can also utilize Claude Opus subagents or skip the external review step if external keys are not configured.

How does the auto-resume feature work?

The skill saves session snapshots to your planning directory. If a session is interrupted or you use the /clear command, Deep Plan can detect the state and resume from the last completed step.

生产力与工作流

Orchestrates a multi-step, AI-assisted implementation planning workflow featuring research, stakeholder interviews, and multi-LLM reviews.

Deep Plan is a sophisticated planning skill for Claude Code designed to reduce technical debt and architectural errors through rigorous pre-implementation analysis. It guides developers through a systematic lifecycle—validating environments, conducting codebase and web research, interviewing stakeholders for clarity, and performing cross-model reviews using Gemini or OpenAI. The final output is a structured, sectionized implementation plan optimized for Test-Driven Development (TDD), ensuring that complex features are well-reasoned and thoroughly vetted before the first line of code is written. It is particularly effective for teams moving from vague requirements to concrete technical specifications.
