Generates and manages structured implementation roadmaps and system overviews for complex coding tasks.
Codex Technical Planner is a specialized skill for Claude Code designed to bridge the gap between ideation and execution. It enables developers to draft, save, and manage structured markdown plans that define technical intent, scope, requirements, and risks. By storing these plans in a centralized local directory ($CODEX_HOME/plans) rather than the project repository, it ensures your codebase remains clean while providing a robust framework for tracking multi-step engineering tasks. Whether you need a granular checklist for a feature rollout or a high-level architectural overview, this skill provides the templates and discovery tools to keep your development workflow organized.
