Delegate coding tasks to OpenAI Codex CLI.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# OpenAI Codex CLI Agent Bridge Delegate code generation, editing, and explanation tasks to the OpenAI Codex CLI. Codex CLI runs GPT-4o in an agentic coding loop with sandboxed code execution. ## When to Use - User wants to generate code using OpenAI's GPT-4o model - Task requires code execution in a sandboxed environment - User wants an alternative to Claude Code using the OpenAI API - User wants to benchmark or compare code generation between providers - Task requires OpenAI-specific features or models ## How to Use ### 1. Install Codex CLI ```powershell # Requires Node.js 18+ npm install -g @openai/codex # Verify codex --version # Set API key $env:OPENAI_API_KEY = "sk-..." ``` ### 2. Run a coding task interactively ```powershell Set-Location "C:\Users\<you>\myproject" codex "Add input validation to all form fields in the React components" ``` ### 3. Non-interactive mode ```powershell # Auto-approve all edits (use with caution) codex --approval-mode auto-edit "Add JSDoc comments to all exported functions in src/" # Full auto mode (applies changes without confirmation) codex --approval-mode full-auto "Fix all ESLint errors in the project" ``` …

How to install
mdr add taracodlabs/aiden/codex@sha256:3052c111d75556c7The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
