Sous-Chef, a Claude Code plugin where Fable reviews, Codex implements

Sous-Chef is a plugin for Claude Code that introduces a two-agent workflow: Fable reviews code and Codex implements changes. It automates code review and implementation cycles within the Claude Code environment.

Background

- **Sous-Chef** is a plugin for **Claude Code** (Anthropic’s terminal-based coding assistant that uses its Claude AI model), letting a second AI agent named **Fable** review code changes while **Codex** (OpenAI’s coding model) implements them. - The approach splits review and implementation between two different AI models — a pattern known as "multi-agent" coding — to catch errors one model alone might miss. - **Fable** is an evaluation framework (also by the same author, Tomáš Čupr) that scores code quality; here it acts as a reviewer that can reject or approve work done by Codex. - This matters because it tests a practical workflow where one AI audits another’s output, aiming to produce more reliable code than a single model acting alone — a live experiment in AI self‑supervision during development.

    Newer Claude models sometimes invent extra keys in tool call arguments, breaking validation in Pi's edit tool. The author suspects post-training for Claude Code's forgiving harness makes alternative schemas fail. This suggests closed RL training can degrade general tool-use reliability.

    Simon Willison released llm-coding-agent 0.1a0, an experimental coding agent built on his LLM library. The agent provides tools for reading, editing, searching files and executing commands, and ships with a Python API and CLI. It was developed using Claude Code (Fable 5) via TDD with a spec-first approach, and is available as a slop-alpha on PyPI.
