newcode 0.1.15

AI-powered code generation agent platform

NewCode

An AI-powered code generation and modification agent for the terminal.

NewCode is a fork of code-puppy by Michael Pfaffenberger, customized for the fedstew workflow. We wanted a clean, professional CLI agent with opinionated defaults, streamlined prompts, and a focus on practical code generation without the playful branding.

What changed from code-puppy

• Removed all dog/puppy-themed branding and emojis in favor of a clean, professional interface
• Renamed "Pack" multi-agent system to use functional names (Orchestrator, Tracker, Executor, Reviewer, etc.)
• Rewrote all agent system prompts for clarity and professionalism
• Increased output validation retries from 3 to 10 for more robust model interactions
• Updated configuration keys and display names throughout
• Published to PyPI as newcode instead of code-puppy

Installation

pip install newcode

Or with uv:

uv pip install newcode

Quick Start

# Run the agent
newcode

# Or use the short alias
nc

On first run, you'll be guided through a setup wizard to configure your API keys and preferences.

Requirements

• Python 3.11 - 3.13
• An API key for at least one supported provider (OpenAI, Anthropic, Cerebras, Google Gemini, etc.)

Features

• Multi-model support: OpenAI, Anthropic Claude, Google Gemini, Cerebras, and more
• Multi-agent workflows with specialized agents (Orchestrator, Tracker, Executor, Reviewer, QA Checker, Workspace Manager, Merger)
• File operations: read, write, edit, delete with diff previews and permission prompts
• Shell command execution with safety controls
• Browser-based terminal via built-in API server
• Scheduled task execution with a background daemon
• Plugin system with lifecycle callbacks and event-based hooks
• Interactive TUI menus for configuration, model selection, and task management
• Session auto-save and restore
• MCP (Model Context Protocol) server support

Configuration

Configuration is stored in ~/.config/newcode/puppy.cfg (XDG-compliant paths). The setup wizard handles initial configuration. You can also use CLI commands:

# Inside the agent REPL:
/config          # Show current configuration
/model           # Switch models
/agent           # Switch agents
/scheduler       # Manage scheduled tasks
/colors          # Customize terminal colors

Agents

Agent	Purpose
Code Agent	General-purpose code generation and modification (default)
Orchestrator	Multi-agent workflow coordination
