What is Claude Forge?

Claude Forge is an open-source development environment for Claude Code that provides 11 specialized agents, 36 slash commands, 15 skill workflows, and 14 automation hooks. Often described as "oh-my-zsh for Claude Code", it transforms Claude Code from a basic CLI into a full-featured development environment. One install gives you agents, commands, skills, hooks, and 8 rule files -- all pre-wired and ready to go.

Think of it as oh-my-zsh for Claude Code: the same way oh-my-zsh enhances your terminal, Claude Forge supercharges your AI coding assistant.

⚡ Quick Start

# 1. Clone
git clone --recurse-submodules https://github.com/daeha76/claude-forge.git
cd claude-forge

# 2. Install (macOS / Linux)
./install.sh

# 2. Install (Windows PowerShell)
.\install.ps1

# 3. Launch Claude Code
claude

Both wrappers automatically install dotnet-script if missing, then run install.csx. On macOS/Linux, symlinks are used so git pull updates everything instantly. On Windows, files are copied — re-run install.ps1 after git pull.

If you find Claude Forge useful, please consider giving it a star -- it helps others discover this project.

Step	What happens
/plan	AI creates an implementation plan. Waits for your confirmation before coding.
/tdd	Write tests first, then code. One unit of work at a time.
/code-review	Security + quality check on the code you just wrote.
/handoff-verify	Auto-verify build/test/lint all at once.
/commit-push-pr	Commit, push, create PR, and optionally merge -- all in one.
/sync	Sync project docs (prompt_plan.md, spec.md, CLAUDE.md, rules).

Bug Fix

Fast turnaround for bug fixes with automatic retry:

/explore → /tdd → /verify-loop → /quick-commit → /sync

Step	What happens
/explore	Navigate the codebase to find where the bug lives.
/tdd	Write a test that reproduces the bug, then fix it.
/verify-loop	Auto-retry build/lint/test up to 3 times with auto-fix on failure.
/quick-commit	Fast commit for simple, well-tested changes.
/sync	Sync project docs after commit.

Security Audit

Comprehensive security analysis combining CWE and STRIDE:

/security-review → /stride-analysis-patterns → /security-compliance

Step	What happens
/security-review	CWE Top 25 vulnerability scan + STRIDE threat modeling.
/stride-analysis-patterns	Systematic STRIDE methodology applied to system architecture.
/security-compliance	SOC2, ISO27001, GDPR, HIPAA compliance verification.

Team Collaboration

Parallel multi-agent execution for complex tasks:

/orchestrate → Agent Teams (parallel work) → /commit-push-pr

Step	What happens
/orchestrate	Create an Agent Team with file-ownership separation and hub-and-spoke coordination.
Agent Teams	Multiple agents work in parallel on frontend, backend, tests, etc.
/commit-push-pr	Merge all work, verify, and ship.

📥 Claude Forge Installation Guide

Prerequisites

Dependency	Required	Notes
Node.js	✅	For MCP servers (npx)
Git	✅	Clone, submodules
Claude Code CLI	✅	claude command
.NET SDK	✅	Runs install.csx + .NET project creation
dotnet-script	auto-installed	C# script engine

All Platforms (Windows / macOS / Linux)

All logic lives in a single C# script — install.csx.

# macOS / Linux
git clone --recurse-submodules https://github.com/daeha76/claude-forge.git
cd claude-forge
chmod +x install.sh && ./install.sh

# Windows (PowerShell)
git clone --recurse-submodules https://github.com/daeha76/claude-forge.git
cd claude-forge
.\install.ps1

# Or run directly on any platform (requires dotnet-script)
dotnet script install.csx

dotnet-script is installed automatically if missing. Manual install: dotnet tool install -g dotnet-script

The installer:

1. Checks dependencies (node, git, dotnet)
2. Initializes git submodules (CC CHIPS)
3. Backs up existing ~/.claude/ if present
4. Creates symlinks (macOS/Linux) or copies (Windows) to ~/.claude/
5. Applies CC CHIPS custom overlay
6. Optionally installs MCP servers and external skills
7. Adds shell aliases (cc → claude, ccr → claude --resume) — macOS/Linux only

Create a New .NET Project

# macOS / Linux
./install.sh MyApp

# Windows
.\install.ps1 MyApp

# Specify a custom location (macOS / Linux)
./install.sh MyApp ~/Desktop
# → /Users/yourname/Desktop/MyApp

# Specify a custom location (Windows)
.\install.ps1 MyApp D:\\projects
# → D:\projects\MyApp

# Or directly (any platform)
dotnet script install.csx -- MyApp D:\\projects

This scaffolds a full .NET Clean Architecture solution next to the claude-forge folder:

MyApp/
  src/
    MyApp.Domain/          # Entities, value objects
    MyApp.Application/     # Use cases, interfaces
    MyApp.Infrastructure/  # DB, external services
    MyApp.Api/             # ASP.NET Core Web API
    MyApp.Web/             # Blazor Auto frontend
    MyApp.AppHost/         # .NET Aspire orchestrator
  tests/
    MyApp.Domain.Tests/
    MyApp.Application.Tests/
  .claude/                 # Claude Forge features (copied)
  CLAUDE.md                # Project context for Claude
  run.csx                  # Start dev server

MCP Server Setup

Server	API Key	Notes
context7	No	Real-time library docs
memory	No	Persistent knowledge graph
playwright	No	Browser automation
sequential-thinking	No	Step-by-step reasoning
github	GITHUB_PERSONAL_ACCESS_TOKEN	Repo / PR / Issues
supabase	Supabase URL/Key	Direct DB integration

Customization

Override settings without modifying tracked files:

cp setup/settings.local.template.json ~/.claude/settings.local.json
vim ~/.claude/settings.local.json

settings.local.json merges on top of settings.json automatically.

Frequently Asked Questions

What is Claude Forge?

Claude Forge is an open-source development environment for Claude Code. It bundles 11 specialized agents, 36 slash commands, 15 skill workflows, 14 automation hooks, and 8 rule files into a single install. Think of it as "oh-my-zsh for Claude Code" -- it turns the basic Claude Code CLI into a fully equipped coding environment with built-in workflows for planning, TDD, security review, and deployment.

How is Claude Forge different from other Claude Code plugins?

Most Claude Code plugins solve one problem at a time. Claude Forge is a complete development environment -- agents, commands, skills, hooks, and rules that work together as a cohesive system. Instead of assembling individual plugins and configuring each one, Claude Forge gives you a pre-wired pipeline: /plan feeds into /tdd, which feeds into /code-review, which feeds into /handoff-verify, which feeds into /commit-push-pr. The 6-layer security hook system also runs automatically without extra configuration.

Is Claude Forge compatible with the official Claude Code plugin system?

Yes. Claude Forge installs via symlinks to ~/.claude/ and works alongside official Claude Code plugins. Your existing settings.local.json overrides are preserved, and you can add or remove individual components without affecting the rest of the system.

How do I update Claude Forge?

Run git pull in the claude-forge directory. Because the installer uses symlinks (on macOS/Linux), updates take effect immediately -- no re-install needed. On Windows, re-run install.ps1 after pulling to copy the updated files.

Does Claude Forge work on Windows?

Yes. Run install.ps1 in PowerShell as Administrator. Windows uses file copies instead of symlinks, so you need to re-run install.ps1 after each git pull to apply updates. All agents, commands, skills, and hooks work the same on Windows, macOS, and Linux.

What does /sync do?

/sync synchronizes your project's memory and documentation. It pulls the latest changes from the remote repository and then syncs all project docs -- prompt_plan.md, spec.md, CLAUDE.md, and rule files. Run it after completing any workflow (feature, bug fix, refactor) or at the start of a new session to ensure Claude has the latest context.

How does Claude Forge handle memory across sessions?

Claude Forge uses a 3-layer memory system:

1. Project docs (CLAUDE.md, prompt_plan.md, spec.md) -- Project-level instructions and plans that persist in the repository. /sync keeps these up to date.
2. Rule files (rules/) -- Coding style, security, workflow conventions loaded automatically each session.
3. MCP memory server -- A persistent knowledge graph that stores entities and relations across sessions.

Running /sync at session start ensures layers 1 and 2 are current. The MCP memory server (layer 3) persists automatically.
