Turbo

A modular collection of Claude Code skills that speed up everyday dev tasks while keeping quality high. Heavily optimized and battle-tested with Claude Code and the Opus model.

TL;DR — Three steps to ship:

1. Plan — Enter plan mode and describe what you want to build
2. Implement — Build it with Claude
3. Run /finalize — Tests, code simplification, AI review, commit, and PR. One command.

Everything else in Turbo builds on this loop: planning pipelines for large projects, debugging tools for when things break, and self-improvement that makes each session teach the next. There are 30+ skills beyond /finalize. Read on for the full picture.

What Is This?

Turbo is a skill set for Claude Code. Each skill teaches Claude a specific workflow: reviewing code, creating PRs, investigating bugs, self-improving from session learnings, and more. The skills are designed to work together.

The key idea: skills aren't just standalone tools you use next to each other. They're puzzle pieces that connect into larger workflows. The main orchestrator, /finalize, chains testing, code simplification, AI review, committing, and PR creation into one command. But each piece is small and swappable. Replace one skill with your own and the rest of the pipeline still works.

The other core piece is /self-improve, which makes the whole system compound. After each session, it extracts lessons from the conversation and routes them to the right place: project CLAUDE.md, auto memory, or existing/new skills. Every session teaches Claude something, and future sessions benefit.

What It's Not

Turbo amplifies your existing process. If your plan is vague, your architecture is unclear, and you skip every review finding, Turbo won't save you. Garbage in, garbage out.

It works best when your project has the right infrastructure in place:

• Tests — /finalize runs your test suite and writes missing tests. Without tests, there's no safety net. If your project doesn't have automated tests, /smoke-test (standalone skill, not part of /finalize) can fill the gap by launching your app and verifying changes manually, but real tests are always better.
• Linters and formatters — /finalize runs your linter after code review fixes. If you don't have one, style issues slip through.
• Dead code analysis — /find-dead-code (standalone skill, not part of /finalize) identifies unused code via parallel analysis, but it's even better when your project already has tools like knip, vulture, or periphery integrated.

The target audience is experienced developers who want to move faster without sacrificing quality. That said, beginners are welcome too. Turbo is a great way to learn how a professional dev workflow looks. Just don't blindly trust outputs. Review what Claude produces, understand why it made those choices, and build your own judgment alongside it.

The Puzzle Piece Philosophy

Every skill is a self-contained piece. Orchestrator skills like /finalize compose them into workflows, but each piece works independently too.

Want to swap a piece? For example:

• Replace /oracle with your own setup (it's macOS-only and has a cookies workaround)
• Replace /commit-rules with your team's commit convention. The pipeline adapts.

The skills communicate through standard interfaces (git staging area, PR state, file conventions), not tight coupling.

Sponsorship

If Turbo has helped you ship faster and you're so inclined, I'd greatly appreciate it if you'd consider sponsoring my open source work.

Loading

Quick Start

Prerequisites

Turbo requires Claude Code. Works best with Claude Code Max 5x, Max 20x, or Team plan with Premium seats (orchestrator workflows are context-heavy). Additional tools are installed during setup (steps 5 and 6).

External services: ChatGPT Plus or higher (for codex review), and ChatGPT Pro or Business (for /oracle, where Pro models are the only ones that reliably solve very hard problems). That said, /peer-review and /oracle are designed as swappable puzzle pieces, so if you don't have access, replace them with alternatives that work for you.

Automatic Setup (Recommended)

Open Claude Code and prompt:

Walk me through the Turbo setup. Read SETUP.md from the tobihagemann/turbo repo and guide me through each step.

Claude will clone the repo, copy the skills, configure your environment, and walk you through each step interactively.

Updating

Run /update-turbo in Claude Code to update all skills. It fetches the latest update instructions from GitHub, builds a changelog, handles conflict detection for customized skills, and manages exclusions.

Manual Setup

See SETUP.md for the full guide, or follow the steps below.

1. Clone the Repo

Clone (or fork) the Turbo repo to ~/.turbo/repo/:

git clone https://github.com/tobihagemann/turbo.git ~/.turbo/repo

To contribute improvements back, fork the repo on GitHub first, then clone your fork and add the upstream remote:

git clone https://github.com/<your-username>/turbo.git ~/.turbo/repo
cd ~/.turbo/repo && git remote add upstream https://github.com/tobihagemann/turbo.git

2. Copy Skills

Copy all skill directories to your global skills location:

for skill in $(ls ~/.turbo/repo/skills/); do
  cp -r ~/.turbo/repo/skills/$skill ~/.claude/skills/$skill
done

Many skills depend on each other (e.g., /finalize orchestrates /simplify-code, /peer-review, /evaluate-findings, and more), so installing only a subset will leave gaps in the workflows.

3. Initialize Config

Create ~/.turbo/config.json:

mkdir -p ~/.turbo
cat > ~/.turbo/config.json << EOF
{
  "repoMode": "clone",
  "excludeSkills": [],
  "lastUpdateHead": "$(git -C ~/.turbo/repo rev-parse HEAD)"
}
EOF

Set repoMode to "clone" (consumer), "fork" (contributor), or "source" (maintainer).

4. Add .turbo to Global Gitignore

Some skills store project-level files in a .turbo/ directory (specs, prompt plans, improvements). Add it to your global gitignore to keep project repos clean:

mkdir -p ~/.config/git
echo '.turbo/' >> ~/.config/git/ignore

This uses Git's standard XDG path ($XDG_CONFIG_HOME/git/ignore), which Git reads automatically without needing core.excludesfile. If core.excludesfile is already set, add .turbo/ to that file instead.

5. Install Prerequisites

GitHub CLI is used by many skills for PR operations, review comments, and repo queries:

brew install gh
gh auth login

Codex CLI is used by /peer-review for AI-powered code review during /finalize. Requires ChatGPT Plus or higher:

npm install -g @openai/codex

6. Install Companion Skills (Recommended)

The /smoke-test skill uses external skills for browser and UI automation:

Skill	What it's for	Install
agent-browser	Browser automation for web app smoke testing (highly recommended)	npx skills add https://github.com/vercel-labs/agent-browser --skill agent-browser --agent claude-code -y -g
peekaboo	macOS UI automation for native app smoke testing	npx skills add https://github.com/openclaw/openclaw --skill peekaboo --agent claude-code -y -g

Without these, /smoke-test falls back to terminal-based verification.

7. Allow All Skills

Orchestrator workflows like /finalize invoke many skills in sequence. Without allowlisting them, you'll get prompted for each one, breaking the flow.

Add all Turbo skills to the permissions.allow array in ~/.claude/settings.json. Generate the entries from the local repo:

ls ~/.turbo/repo/skills/ | sed 's/.*/"Skill(&)"/'

Merge the output into your existing permissions.allow array.

8. Configure Context Tracking

Turbo workflows like /finalize consume significant context. Knowing how much context you have left prevents unexpected compaction mid-workflow.

Add this to ~/.claude/settings.json:

{
  "statusLine": {
    "type": "command",
    "command": "jq -r '\"\\(.context_window.remaining_percentage | floor)% context left\"'"
  }
}

9. Add Pre-Implementation Prep

Add this to your ~/.claude/CLAUDE.md (create the file if it doesn't exist):

# Pre-Implementation Prep

After plan approval (ExitPlanMode) and before making edits:
1. Run `/code-style` to load code style principles
2. Read all files referenced by the user in their request
3. Read all files mentioned in the plan
4. Read similar files in the project to mirror their style

10. Disable Auto-Compact (Optional)

With the 1M context window, compaction is rarely needed. If you prefer to control compaction timing, disable auto-compact in Claude Code via /config.

11. Oracle Setup (Optional)

The /oracle skill requires additional setup (Chrome, Python, ChatGPT access). See the oracle skill for configuration via ~/.turbo/config.json. If not set up, everything still works.

The Main Workflow

The recommended way to use Turbo:

1. Enter plan mode and plan the implementation
2. Approve the plan (optionally clear context if planning used significant context)
3. Run /finalize when you're done implementing

/finalize runs through these phases automatically:

1. Stage & Test — Stage changed files, write missing tests, run test suite
2. Simplify Code — Multi-agent review for reuse, quality, efficiency, clarity
3. Code Review — AI peer review, evaluate findings, apply fixes, re-test
4. Self-Improve — Extract learnings, route to CLAUDE.md / memory / skills
5. Commit and PR — Branch if needed, commit, push, create or update PR

Context Management Tips

With the 1M context window, running out of context during /finalize is unlikely for most sessions. If you do hit the limit on very long sessions:

• Run /self-improve before /compact. Compaction loses conversational detail that /self-improve mines for lessons. Capture learnings first, then compact.
• The status line from step 6 above makes remaining context easy to track.

Self-Improvement

/self-improve is another core skill. Run it anytime before your context runs out (it's also part of /finalize Phase 4). It scans the conversation for corrections, repeated guidance, failure modes, and preferences, then routes each lesson to the right place: project CLAUDE.md, auto memory, or existing/new skills. It routes lessons through Claude Code's built-in knowledge layers and, over time, makes Claude better at your specific project.

/note-improvement captures improvement opportunities that come up during work but are out of scope: code review findings you chose to skip, refactoring ideas, missing tests. These get tracked in .turbo/improvements.md so they don't get lost. Since .turbo/ is gitignored, it doesn't clutter the repo. When you're ready to act on them, /implement-improvements validates each entry against the current codebase (filtering out stale items), then plans and implements the remaining ones.

The Planning Pipeline (Optional)

For larger projects, Turbo offers a full spec-to-implementation pipeline. You can skip this entirely and jump straight to implementation + /finalize.

1. Run /create-spec — Guided discussion that produces a spec at .turbo/spec.md
2. Run /create-prompt-plan — Breaks the spec into context-sized prompts at .turbo/prompts.md
3. For each prompt, open a new session:
   1. Enter plan mode and run /pick-next-prompt
   2. Approve the plan (optionally clear context if planning used significant context)
   3. Implement the changes
   4. Run /finalize

Each session handles one prompt to keep context focused.
