JustEvery_ Code

 

 

Code is a fast, local coding agent for your terminal. It's a community-driven fork of openai/codex focused on real developer ergonomics: Browser integration, multi-agents, theming, and reasoning control — all while staying compatible with upstream.

 

Why Code

• 🌐 Browser Integration - CDP support, headless browsing, screenshots
• 📝 Diff Viewer - Side-by-side diffs with syntax highlighting
• 🤖 Multi-Agent Commands - /plan, /solve, /code with agent panels
• 🎨 Theme System - /themes with live preview and accessibility
• 🧠 Reasoning Control - /reasoning for dynamic effort adjustment
• 🔌 MCP support – Extend with filesystem, DBs, APIs, or your own tools.
• 🔒 Safety modes – Read-only, approvals, and workspace sandboxing.
• 🔁 Backwards compatible – Supports ~/.codex/* or default ~/.coder/*

 

Simple interface	Unified diffs

Browser control	Assist with Claude & Gemini

 

Quickstart

Run

npx -y @just-every/code

Install & Run

npm install -g @just-every/code
code // or `coder` if you're using VS Code

Note: If another tool already provides a code command (e.g. VS Code), our CLI is also installed as coder. Use coder to avoid conflicts.

Authenticate (one of the following):

• Sign in with ChatGPT (Plus/Pro/Team; uses models available to your plan)
  • Run code and pick "Sign in with ChatGPT"
  • Stores creds locally at ~/.coder/auth.json (also reads legacy ~/.codex/auth.json)
• API key (usage-based)
  • Set export OPENAI_API_KEY=xyz and run code

Install Claude & Gemini (optional)

Code supports orchestrating other AI CLI tools. Install these and config to use alongside Code.

npm install -g @anthropic-ai/claude-code @google/gemini-cli && claude "Just checking you're working! Let me know how I can exit." && gemini -i "Just checking you're working! Let me know how I can exit."

 

Commands

Browser

# Connect code to external Chrome browser (running CDP)
/chrome        # Connect with auto-detect port
/chrome 9222   # Connect to specific port

# Switch to internal browser mode
/browser       # Use internal headless browser
/browser https://example.com  # Open URL in internal browser

Agents

# Plan code changes (Claude, Gemini and GPT-5 consensus)
# All agents review task and create a consolidated plan
/plan "Stop the AI from ordering pizza at 3AM"

# Solve complex problems (Claude, Gemini and GPT-5 race)
# Fastest preferred (see https://arxiv.org/abs/2505.17813)
/solve "Why does deleting one user drop the whole database?"

# Write code! (Claude, Gemini and GPT-5 consensus)
# Creates multiple worktrees then implements the optimal solution
/code "Show dark mode when I feel cranky"

General

# Try a new theme!
/themes

# Change reasoning level
/reasoning low|medium|high

# Start new conversation
/new

CLI reference

code [options] [prompt]

Options:
  --model <name>        Override the model (gpt-5, claude-opus, etc.)
  --read-only          Prevent file modifications
  --no-approval        Skip approval prompts (use with caution)
  --config <key=val>   Override config values
  --oss                Use local open source models
  --sandbox <mode>     Set sandbox level (read-only, workspace-write, etc.)
  --help              Show help information
  --debug             Log API requests and responses to file
  --version           Show version number

 

Memory & project docs

Code can remember context across sessions:

1. Create an AGENTS.md or CLAUDE.md file in your project root:

# Project Context
This is a React TypeScript application with:
- Authentication via JWT
- PostgreSQL database
- Express.js backend

## Key files:
- `/src/auth/` - Authentication logic
- `/src/api/` - API client code  
- `/server/` - Backend services

2. Session memory: Code maintains conversation history
3. Codebase analysis: Automatically understands project structure

 

Non-interactive / CI mode

For automation and CI/CD:

# Run a specific task
code --no-approval "run tests and fix any failures"

# Generate reports
code --read-only "analyze code quality and generate report"

# Batch processing
code --config output_format=json "list all TODO comments"

 

Model Context Protocol (MCP)

Code supports MCP for extended capabilities:

• File operations: Advanced file system access
• Database connections: Query and modify databases
• API integrations: Connect to external services
• Custom tools: Build your own extensions

Configure MCP in ~/.codex/config.toml:

[[mcp_servers]]
name = "filesystem"
command = "npx"
args = ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/project"]

 

Configuration

Main config file: ~/.codex/config.toml

# Model settings
model = "gpt-5"
model_provider = "openai"

# Behavior
approval_policy = "on_request"  # untrusted | on-failure | on-request | never
model_reasoning_effort = "medium" # low | medium | high
sandbox_mode = "workspace_write"

# UI preferences see THEME_CONFIG.md
[tui.theme]
name = "light-photon"

# Add config for specific models
[profiles.gpt-5]
model = "gpt-5"
model_provider = "openai"
approval_policy = "never"
model_reasoning_effort = "high"
model_reasoning_summary = "detailed"

Environment variables

• CODEX_HOME: Override config directory location
• OPENAI_API_KEY: Use API key instead of ChatGPT auth
• OPENAI_BASE_URL: Use alternative API endpoints

 

FAQ

How is this different from the original?

This fork adds browser integration, multi-agent commands (/plan, /solve, /code), theme system, and enhanced reasoning controls while maintaining full compatibility.

Can I use my existing Codex configuration?

Yes! This fork is fully backward compatible with existing ~/.codex/ configurations.

Does this work with ChatGPT Plus?

Absolutely. Use the same "Sign in with ChatGPT" flow as the original.

Is my data secure?

Yes. Authentication stays on your machine, and we don't proxy your credentials or conversations.
