Production-grade Claude Code workflow OS — agents, skills, hooks, and continuous learning.
npx claudepluginhub marvinrichter/clarcProduction-grade Claude Code workflow OS — agents, skills, hooks, commands, rules, and a continuous learning flywheel for modern software engineering.
marvinrichterThe workflow OS for Claude Code. 63 agents · 249 skills · 178 commands · 20 language rule sets · continuous learning flywheel.
clarc turns Claude Code from a coding assistant into a structured engineering system. It brings together agents that delegate work, skills that encode domain knowledge, commands that run repeatable workflows, hooks that automate the background, and a learning loop that improves itself over time.
clarc ships a complete, opinionated development methodology — from raw idea to shipped code.
Phase 0: Discovery /idea → /evaluate → /explore → /prd
Phase 1: Planning /plan
Phase 2: Implementation /tdd (RED → GREEN → IMPROVE)
Phase 3: Quality /code-review + /security
Phase 4: Ship /commit-push-pr
Skip what you don't need:
| Task | Start here |
|---|---|
| New idea (unsure if worth building) | /idea |
| Feature with clear spec | /plan |
| Bug fix | /tdd (write the failing test first) |
| Refactor | /plan → /tdd |
| Docs / chore | /commit |
Run /clarc-way to get a tailored recommendation for your current task.
Run /quickstart if you're new to clarc.
# 1. Install (pick your language)
npx github:marvinrichter/clarc typescript
npx github:marvinrichter/clarc python
npx github:marvinrichter/clarc go
# 2. Verify the installation
npx github:marvinrichter/clarc doctor
# 3. Open Claude Code and run your first command
# /quickstart → guided tour of the most important workflows
# /clarc-way → what to do for your current task
# Recommended — interactive wizard (auto-detects your languages)
npx github:marvinrichter/clarc
# Or with explicit language(s) — skips the wizard
npx github:marvinrichter/clarc typescript
npx github:marvinrichter/clarc typescript python go
# Other editors
npx github:marvinrichter/clarc --target cursor typescript
npx github:marvinrichter/clarc --target opencode typescript
npx github:marvinrichter/clarc --target codex
# Check if your installed rules are up to date
npx github:marvinrichter/clarc --check
The wizard clones clarc to ~/.clarc/ on first run, then symlinks agents, commands, and rules into ~/.claude/. A single git pull in ~/.clarc/ keeps everything current — no re-install needed.
~/.claude/agents/tdd-guide.md → ~/.clarc/agents/tdd-guide.md (symlink)
~/.claude/commands/plan.md → ~/.clarc/commands/plan.md (symlink)
~/.claude/rules/common/*.md → ~/.clarc/rules/common/*.md (symlinks)
Your own agents or rules placed in ~/.claude/agents/ or ~/.claude/rules/ are never touched — symlinks only fill in files that don't already exist there.
# Update clarc
cd ~/.clarc && git pull
# Force copy instead of symlinks (CI, containers, cross-filesystem)
npx github:marvinrichter/clarc --copy typescript
git clone [email protected]:marvinrichter/clarc.git ~/.clarc
~/.clarc/install.sh typescript
~/.clarc/install.sh --enable-learning typescript
~/.clarc/install.sh --check
| Component | Count | Purpose |
|---|---|---|
| Agents | 63 | Specialized subagents — delegate planning, review, testing, debugging |
| Skills | 249 | Domain knowledge — patterns, conventions, examples for specific tasks |
| Commands | 178 | Slash commands — repeatable workflows triggered by /command |
| Rules | 20 | Language rule sets — always-on coding standards and checklists |
| Hooks | — | Background automations — format, lint, persist state, weekly digests |
Agents are delegated automatically based on what you're doing. You can also invoke them explicitly.
