Codex Plugin for Claude Code
OpenAI
Codex Plugin for Claude Code lets you invoke OpenAI Codex from inside Claude Code for reviews, adversarial checks, and delegated background tasks.
Key features
- Codex Code Review Slash Commands: /codex:review runs a normal Codex read-only review of uncommitted changes or a branch against a base ref like main.
- Adversarial Review: /codex:adversarial-review runs a steerable review that questions the design and pressure-tests assumptions, tradeoffs, and failure modes.
- Delegated Rescue Tasks: /codex:rescue hands off tasks to a codex-rescue subagent so Codex can investigate bugs, try fixes, or continue previous Codex threads.
- Session Hand-Off: /codex:transfer moves the current Claude Code session over to Codex for continued work, keeping context intact.
- Background Job Management: /codex:status, /codex:result, and /codex:cancel manage long-running Codex jobs kicked off in the background.
- Zero-Setup Onboarding: /codex:setup detects whether Codex is installed and logged in and can offer to install it via npm if missing.
Best for
- Second-Opinion Code Review: Ask Codex to review the same uncommitted changes Claude Code just produced before shipping.
- Adversarial Design Review: Pressure test a chosen implementation for auth, data-loss, rollback, race-condition, or reliability risks before merge.
- Delegating Bug Investigations: Hand off a bug investigation to Codex in the background while continuing other work in Claude Code.
- Multi-Agent Coding Workflow: Route different types of tasks (fixes, refactors, reviews) to whichever agent is best suited without leaving Claude Code.
- Branch Reviews Before Merge: Run /codex:review base main to get a Codex review of the entire feature branch as part of your PR process.
Juggler
Julian Storer
A native desktop workbench for AI coding agents with branching conversation trees, inspectable tool calls and editable context.
Key features
- Branching Conversation Trees: Fork the session at any point, recursively, so competing approaches and tangents run side by side without polluting the main context.
- Miller Column Navigation: A Finder-style column layout lays out tool calls, item properties and nested sub-threads for long reading and editing sessions.
- Transaction Inspector: Open any model transaction to see the assembled system prompt, messages, tool definitions, output, token use, timing and stop reason.
- The Context Surgeon: Fold history into a new thread, move or copy items between branches, expand a branch back into its parent, and undo structural changes.
- Local or Remote Sessions: Run the desktop app locally or the headless binary on the machine holding the code, then attach from the app, a browser or a phone.
- Durable Sessions: Sessions are stored on disk as live-synced Yjs documents, so quits, relaunches and dropped connections do not lose the conversation.
- Automatic Context Sizing: Juggler measures the full request before each call, reserves room for the answer and compacts older history before limits become an error.
- Inspectable MCP Tools: Follow an MCP handoff end to end - schema offered, arguments generated, approval, result and errors - with server status, logs and per-tool filtering.
- JavaScript Extension SDK: Context items, LLM loop strategies, slash commands, viewers and Pinboard tabs are extensions you can fork or replace, under a permissive Apache-2.0 SDK.
Best for
- Exploring Competing Fixes: Branch a thread into two sub-threads to try different approaches to the same bug and compare results before committing.
- Auditing Agent Behavior: Inspect exactly what the model received and returned when an agent makes a surprising edit to the codebase.
- Remote Development: Run the server on a dev box or GPU machine where the repository lives and drive the same live session from a laptop or browser.
- Long Refactors: Keep a multi-hour session alive across quits and reconnects, with the agent paused awaiting approval for its next step.
- Provider Comparison: Drive Claude Code, Codex, Copilot, Gemini and local Ollama models through one interface to compare behavior on the same task.
- Custom Tooling: Write JavaScript extensions that add slash commands, file viewers or new LLM loop strategies to the workbench.
