# Install verified Codex planning and completion loops with LazyCodex

Add Codex commands, skills, hooks, diagnostics, and sub-agent roles for deep repository initialization, planning, execution, and evidence-backed completion.

## Prerequisites

Node.js, npm or npx, Codex

## Installation

Use the upstream install or setup path that matches your environment:
- npx lazycodex-ai install
- One line. No global install, no npm i -g. Always use npx:
- npx lazycodex-ai install --no-tui --codex-autonomous
- npx lazycodex-ai doctor

Requirements and caveats from upstream:
- | programming | Strict TypeScript, Rust, Python, or Go discipline |

Basic usage or getting-started notes:
- The npx installer above stays the primary path. As an additive, experimental
- alternative you can install from inside Codex itself: type /plugins, open the
- **Add Marketplace** tab ("Add a marketplace from a Git repo or local root."),
