Now on NPM!

Steps:

1. install using: npm install -g @nodemixaholic/7coder
2. find your global root using npm root -g, append '/@nodemixaholic/7coder' to it (could be something slightly differnet on Windows, I'm not sure, I'm on macOS.)
3. change directory to that
4. find the .env.example file in that folder
5. copy it to ".env" and then edit ".env" using your favorite plaintext editor (mine is nano!)
6. you can now use 7coder by typing 7coder in your terminal

Cheat Sheet

Interactive REPL (default)

 index.js

One-shot task (non-interactive)

 index.js --prompt "Create a todo list app in React with localStorage"
 # Short form
 index.js -p "Build a simple HTTP server in Node"

HTTP OpenAI-compatible endpoint (use with Cursor, Windsurf, Continue.dev, etc.)

 index.js --server
 # or set ENABLE_HTTP_SERVER=true in .env

Background / daemon mode (frees your terminal)

 index.js --background --prompt "Refactor the entire backend"

Permission mode control

 index.js --permission-mode=auto     # Light model decides approvals
 index.js --permission-mode=bypass   # Same as --danger
 index.js --permission-mode=denial   # Block everything

Danger mode (no confirmations)

 index.js --danger --prompt "Install dependencies and run tests"

Help

 index.js --help

How Tools Work

7coder has full tool calling with 40+ production-ready tools:

• read_file / write_file / append_file
• run_command / bash_tool / powershell_tool
• glob_tool / grep_tool (fast file search)
• web_fetch_tool / web_search_tool / web_browser_tool
• computer_use (screenshot, mouse, keyboard — cross-platform)
• agent_tool / remove_agent (spawn child AIs)
• Background tasks, cron jobs, MCP resources, git worktrees
• Notebook editing, skill tools, TODO.md, 7CODER.md auto-generation, etc.

All tools are fully functional — no stubs.

In default mode the AI asks for confirmation on risky actions.
In --danger or --permission-mode=bypass it runs instantly.
Even in bypass mode, super-dangerous commands (rm -rf /, format, dd, etc.) are still blocked.

Every tool action is risk-classified by the light model (LOW / MEDIUM / HIGH).

New Permission & Security System

| Mode | Behavior | | --------- | ------------------------------------------- | | default | Interactive y/n prompts (recommended) | | auto | Light model decides approvals automatically | | bypass | No approvals (same as --danger) | | denial | Block every tool call |

Protected files (.env, .gitconfig, package.json, etc.) can never be auto-edited.
Path traversal and dangerous commands are blocked at every level.

New "Computer Use" Feature

Enable with ENABLE_COMPUTER_USE=true in .env.
Gives the AI real mouse/keyboard/screenshot control on Windows 7, Windows 10/11, macOS, and Linux.

Other Killer Features

• 7CODER.md — AI automatically creates and updates this file in the project root with all findings and progress.
• Ralph Wiggum self-iteration loop — still available (ENABLE_RALPH_MODE=true)
• Anti-frustration system — detects when you’re mad and makes the model extra calm/helpful
• HTTP OpenAI endpoint — works with any UI (Open WebUI, VS Code w/ Cline, etc.)
• In-memory agents, background tasks, cron jobs, MCP resources — fully working
• Light model for risk checks, explanations, and moderation (saves tokens)

Compatibility

• Node.js 13.14.0 → latest (no modern JS syntax used)
• Windows 7 SP1 → Windows 11, macOS, Linux
• Any OpenAI-compatible API (OpenAI, Groq, local LLMs, etc.)

Why 7coder?

Because real Claude Code is expensive and doesn’t run on Windows 7.
This is the free, broad-compatibility, semi-open version that delivers almost everything Claude Code does — with better security controls and zero proprietary code.
