Get Shit Done Multi

Spec-driven development system for AI coding assistants with multi-platform support

Supported Platforms: Claude Code · GitHub Copilot CLI · Codex CLI

What It Does

Get Shit Done Multi (GSD Multi) is a template-based installer that deploys working AI assistant skills and agents to multiple platforms with a single command. Instead of manually configuring your Claude Code, GitHub Copilot CLI, or Codex CLI environment, GSD Multi installs a complete spec-driven development system.

This system transforms AI coding into a structured workflow: define your idea, let AI research and plan, then execute with atomic commits and fresh context. You get clean git history, reproducible builds, and human-in-loop verification at key points.

The multi-platform approach means you can use the same workflow across different AI assistants, switching platforms as needed while maintaining project state.

Quick Start

npx get-shit-done-multi

The installer detects your platform (Claude Code, GitHub Copilot CLI, or Codex CLI) and deploys 29 skills and 13 agents. After installation, start your first project with platform-specific commands:

# Claude Code / GitHub Copilot CLI
/gsd-new-project

# Codex CLI
$gsd-new-project

The system guides you through questioning, research, requirements extraction, and roadmap creation. Then execute phase by phase with atomic task plans and clean commits.

Note: Use /gsd- prefix for Claude and Copilot, $gsd- prefix for Codex.

Beta Version

Test the latest features before stable release:

npx get-shit-done-multi@beta

The beta version includes pre-release features from the dev branch.

User Input → Orchestrator → Specialized Agents → Verification

Phases:
┌────────────────┐    ┌────────────────┐    ┌────────────────┐
│ 1. Discuss     │ →  │ 2. Plan        │ →  │ 3. Execute     │

└────────────────┘    └────────────────┘    └────────────────┘
                                                      ↓
┌────────────────┐    ┌────────────────┐    ┌────────────────┐
│ 6. Complete    │ ←  │ 5. Iterate     │ ←  │ 4. Verify      │
│ (Milestone)    │    │ (Next phase)   │    │ (Human check)  │
└────────────────┘    └────────────────┘    └────────────────┘

Each phase produces small, focused plans that execute in fresh context windows to avoid degradation. Human verification happens at natural checkpoints.

GSD Workflow Commands

The complete workflow cycle uses these commands:

• /gsd-new-project or $gsd-new-project — Start new project with guided setup
• /gsd-discuss-phase <N> — Explore phase approach through questions
• /gsd-research-phase <N> — Research implementation patterns
• /gsd-plan-phase <N> — Create atomic execution plans
• /gsd-execute-phase <N> — Execute all plans with fresh context
• /gsd-verify-work — Manual acceptance testing
• /gsd-complete-milestone — Archive and prepare next milestone

See How GSD Works for detailed workflow explanation.

Supported Platforms

• Claude Code - Skills-based system with slash commands (replaces legacy .claude/commands/)
• GitHub Copilot CLI - Conversational interface with agent support
• Codex CLI - OpenAI's command-line interface

All platforms share the same workflow and project state. Switch between platforms mid-project as needed.

Note for Claude users: GSD Multi uses Claude's skills system (.claude/skills/). The legacy commands directory (.claude/commands/) has been deprecated by Claude in favor of skills, which provide the same slash command interface with additional features like frontmatter control and automatic loading. See Platform Specifics for details.

This project (GSD Multi) is a multi-platform fork of the original get-shit-done framework by Lex Christopherson.

Fork Point: v1.6.4 (https://github.com/glittercowboy/get-shit-done/releases/tag/v1.6.4)

Version Timeline:

• v1.7.0 (2026-01-19): Multi-CLI support experiments (Codex CLI added)
• v1.8.0 (2026-01-20): Milestone archiving and mapping improvements
• v2.0.0 (current): Full multi-platform + template system achievement

Key Differences:

• Original: Claude-only with direct .md skills
• GSD Multi: Multi-platform support (Claude, Copilot, Codex) using templating system
