claudex: Autonomous Claude and Codex review loop for software planning

Repositorypromptadvisers/claudexTool

claudex links Claude Code and Codex into an automated terminal loop. Claude creates development plans from short prompts, while Codex reviews them across multiple rounds covering architecture, security, and operations before Claude revises.

Key points

  1. Two-model architecture: Claude acts as the writer and planner, while Codex serves as an independent critic.
  2. Multi-stage perspective reviews: Review rounds sequentially adopt senior engineering, security, and ops perspectives.
  3. Single-window execution: Operates inside Claude Code via a slash command (/claudex:plan) without manual intervention.
  4. Requirements: Demands the Claude Code CLI alongside a ChatGPT subscription (Plus, Pro, Team, or Enterprise) for Codex authentication.
  5. Maintenance model: The open GitHub repository is a v1 teaching artifact, with ongoing releases hosted in an external Skool community.

Why it matters

Autonomous coding agents frequently suffer from blind spots when validating their own proposals. Cross-examining outputs using two distinct models with predefined review lenses significantly hardens technical implementation plans before code is generated.

Analysis

The project targets a major flaw in self-correcting LLM setups: models struggle to break out of their own reasoning ruts. Using Codex to stress-test Claude's architectural proposals introduces valuable friction. However, prospective users should note its lifecycle status: the GitHub repository serves as a foundational v1 educational release, while active maintenance and feature updates are directed toward a commercial Skool community.
