moarcode

You design, Claude writes, Codex reviews, and Gemini doesn't get installed

Why

I have found Claude to be pretty good at writing code, but it's not as conscientious as I'd like. I've found Codex to be excellent at reviewing code, but a fussy and not particularly inspired writer.

I like to discuss an idea with Claude until we've got a decent implementation plan, get Codex to weigh in on that plan, and then just let them go at it, Claude writing, Codex reviewing.

I would like to weigh in only when absolutely needed after that point, so we sandbox this into a Docker container, and let them go at it. This is my workflow for doing that.

Get it running

Step one: clone this repo to somewhere on your machine

Step two: Conceptually, you add a moarcode directory to your project, and then run ./develop.sh:

cd your-project
.../path/to/moarcode/install.sh
cd ./moarcode
./develop.sh

install.sh copies moarcode to your project, adds it to .gitignore, and prepends some information about it to your CLAUDE.md. You will also need to confirm the project name at this point: it's used to name Docker images and volumes, so you can run moarcode in multiple projects simultaneously.

When you run ./develop.sh it'll get you to log in to Codex and then Claude, caching your session credentials in ./moarcode/.credentials/.

Claude starts in fully autonomous mode. It reads IMPLEMENTATION.md for its plan. The default plan starts with M0: understand the codebase and draft milestones with you.

Upgrading

When you pull updates to the moarcode repo, upgrade your existing projects:

cd your-project
.../path/to/moarcode/upgrade.sh

This updates scripts, the Dockerfile, and config files while preserving your project state (DIARY.md, IMPLEMENTATION.md, CODEX-DIARY.md, credentials, and project name). If you've customized the workflow templates (CLAUDE.md, CODEX-REVIEW-PROMPT.md), it'll show you a diff and ask before overwriting.

Use --yes to skip prompts (also the default in non-interactive/CI contexts).

Advice

• After compaction, I'd consider just restarting the container. You should have enough state, and if you don't, Claude likes to play a bit faster and looser with what you've asked it
• You may need to remind Claude it needs to take code reviews from Codex. It knows it's meant to, but it can be a little over enthusiastic

Requirements

Docker, Git, a Claude account, an OpenAI account.
