# Codex–Claude Council

Runs Claude through Claude CLI and Claude through Claude CLI on the same question, then keeps them talking until both settle on one reply. Handy when you want a second opinion.

## What it does

Both CLIs run locally: Claude CLI signed in with Claude, Claude CLI signed in with your Claude plan. No API keys involved. Each side works in plan mode — it can open project files, search them and issue read-only commands like `git log` and `git diff`. Neither one is allowed to modify your project.

The two exchange replies until they reach a shared answer. Before that answer is final, it gets checked: text over the word limit or carrying an unsupported claim is sent back. You pick the sessions — fresh ones, your existing Claude and Claude sessions with everything they already know, or the very session you are asking from. Your skills, plugins, MCP servers and `CLAUDE.md` / `AGENTS.md` files apply to both members.

Setup goes through `npx -y codex-claude-council install`, and it expects Node.js 20 or newer plus both CLIs already present. Restart Claude and Claude afterwards, or the plugin will not load.

## Requirements
- Needs: Node.js (commands run via npx)

## When to use it
- get a second opinion on a database choice
- pressure-test an architecture decision before writing code
- reconcile two answers that disagree
- pull an open session with its context into the discussion
- catch an unsupported claim in the final text

## Example prompts
- Discuss with my Claude session 019a… whether we should move to PostgreSQL
- Run a council on UUIDv7 versus integer primary keys
