Supercharge Claude Code with 11 AI agents, 36 commands & 15 skills — the claude-code plugin framework inspired by oh-my-zsh. 6-layer security hooks included. 5-min install.
# Add to your Claude Code skills
git clone https://github.com/sangrokjung/claude-forgeClaude Forge is an open-source development environment for Claude Code that provides 11 specialized agents, 40 slash commands, 15 skill workflows, and 15 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 9 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.
Claude Forge is available on the Anthropic Official Plugin Marketplace and can be installed directly from Claude Code:

| Change | Description | |:-------|:------------| | Surgical Changes Principle | New 12th golden principle: only change what was requested. No drive-by refactoring, style drift, or adjacent "improvements". Inspired by Andrej Karpathy's observations on LLM coding pitfalls. | | State Assumptions Before Coding | New interaction rule: surface assumptions and present alternatives before implementing ambiguous requirements -- don't guess silently. | | Anti-Rationalization Expansion | Two new entries block common LLM excuses: "while I'm here, let me clean up" and "need abstraction for extensibility". |
| Change | Description |
|:-------|:------------|
| Verification Rules | New verification.md rule enforces evidence-based completion -- no claims without fresh test/build output. |
| Agent Self-Evolution | Core 5 agents (planner, architect, code-reviewer, security-reviewer, tdd-guide) now record learnings in ~/.claude/agent-memory/ after each task. |
| Hook Sync | Added forge-update-check.sh (session start update notification) and observe.sh (continuous learning observation). |
If you're new to development or Claude Code, start with these:
| Step | What to do |
|:-----|:-----------|
| 1 | Run /guide after install -- an interactive 3-minute tour |
| 2 | Read First Steps -- glossary + TOP 6 commands |
| 3 | Browse Workflow Recipes -- 5 copy-paste scenarios |
Or just type /auto login page and let Claude Forge handle the entire plan-to-PR pipeline for you.
Real-world workflows that chain commands, agents, and skills together.
Build new features with a plan-first, test-first approach:
/plan → /tdd → /code-review → /handoff-verify → /commit-push-pr → /sync

| 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). |
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. |
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. |
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. |
Most developers either use Claude Code with no customization or spend hours assembling individual configs. Claude Forge gives you a production-ready setup in 5 minutes.
