# Optimize Turborepo Monorepos

Turborepo setup can be hard when tasks, cache inputs, filters, and CI settings interact. This skill gives focused guidance for reliable monorepo builds and faster pipelines.

## Install

```bash
npx skillstore add vercel/turborepo

## Capabilities

- Explains how to define package-level tasks and register them in turbo.json.
- Guides cache configuration with outputs, inputs, env, globalEnv, and globalDependencies.
- Provides filter and affected-package patterns for local development and CI.
- Documents remote cache setup, token variables, and artifact signing options.
- Helps structure internal packages and avoid common monorepo dependency mistakes.
- Covers Turborepo CI patterns for GitHub Actions and Vercel deployments.

## Use Cases

- Set Up a New Monorepo: Create package scripts, root turbo.json tasks, cache outputs, and workspace structure for a new JavaScript monorepo.
- Improve CI Build Speed: Use affected-package filters, remote caching, and CI-specific Turborepo commands to reduce unnecessary work.
- Debug Cache Misses: Identify missing outputs, incorrect inputs, environment variable issues, and task dependency mistakes that break caching.

## Prompt Templates

### Create Basic Tasks

```
Help me add Turborepo build, lint, and test tasks for my apps and packages. Explain which files should change and why.
```

### Fix Cache Configuration

```
Review my Turborepo cache behavior. Check outputs, inputs, env variables, and dependsOn settings for likely cache misses.
```

### Optimize CI Filters

```
Design a CI plan that runs only affected Turborepo packages while still testing dependents and shared packages correctly.
```

### Plan Secure Remote Cache

```
Help me configure Turborepo remote caching for local development and CI. Include token handling, signing, and failure modes.
```

## Limitations

- It provides guidance and examples; it does not verify a repository automatically.
- Commands may install packages, authenticate services, or run builds if a user executes them.
- It assumes JavaScript or TypeScript monorepo conventions with Turborepo.
- Remote cache and secret handling still require project-specific security review.

## Best Practices

- Put task logic in package scripts and let the root package.json delegate through turbo run.
- Declare outputs, inputs, and environment variables so cache behavior matches real build inputs.
- Review generated commands before execution, especially package installation or remote cache authentication commands.

## Anti Patterns

- Do not place build, lint, or test implementation logic directly in the root package.json.
- Do not use broad .env patterns globally when only specific packages need those variables.
- Do not pass secrets through build tasks unless they are required at runtime and do not affect outputs.

## Security Audit

- Audited at: 2026-07-07T07:32:32.602\+00:00
- Summary: Static analysis reported command, filesystem, network, environment, and credential patterns, but review found these are Markdown guidance and configuration examples for Turborepo. No prompt injection, malicious exfiltration, executable payload, or unauthorized network behavior was found in the cited files.
