# 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/*`

## Quickstart
### Run
```bash
npx -y @just-every/code
```
### Install & Run
```bash
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.
```bash
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
```bash
# 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
```bash
# 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
```bash
# Try a new theme!
/themes
# Change reasoning level
/reasoning low|medium|high
# Start new conversation
/new
```
## CLI reference
```shell
code [options] [prompt]
Options:
--model Override the model (gpt-5, claude-opus, etc.)
--read-only Prevent file modifications
--no-approval Skip approval prompts (use with caution)
--config Override config values
--oss Use local open source models
--sandbox 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:
```markdown
# 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:
```shell
# 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`:
```toml
[[mcp_servers]]
name = "filesystem"
command = "npx"
args = ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/project"]
```
## Configuration
Main config file: `~/.codex/config.toml`
```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.
