Codex Automation

About

Delegates intensive implementation tasks to the Codex CLI, enabling a 'vibe coding' environment where features are designed and then executed without constant approval prompts. This skill provides a specialized automation mode that allows Claude to implement plans, fix bugs, and refactor code autonomously. With configurable sandbox levels—ranging from read-only analysis to workspace-wide write access—it balances safety with efficiency, making it ideal for developers who want to focus on high-level architecture while offloading repetitive coding and execution steps to a specialized automation engine.
