## What it does

This skill guides agents through pnpm dependency workflows in JavaScript and TypeScript repositories. It establishes conventions for monorepo structures, preferring pnpm over npm or yarn to keep lockfiles consistent and make use of content-addressable storage.

Inside, the skill details configurations for `pnpm-workspace.yaml`, targeted task execution using `--filter`, and recursive multi-package runs with `-r`. It provides `.npmrc` settings that balance package isolation against tooling needs, noting selective hoisting patterns with `public-hoist-pattern`.

Docker workflows leverage `pnpm fetch` alongside offline installations, while indiscriminate hoisting via `shamefully-hoist` is discouraged. Without an established workspace file, multi-package filtering and internal protocols will fail.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill pnpm -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/pnpm/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/pnpm/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill pnpm -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/pnpm/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill pnpm -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/pnpm/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Mindrally/skills pnpm
```

2. **Manually: put the files in place**
- File: `.github/skills/pnpm/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill pnpm -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Mindrally/skills --path pnpm
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/pnpm/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill pnpm -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Mindrally/skills/tree/HEAD/pnpm/SKILL.md

## When to use it
- configure monorepo architecture using `pnpm-workspace.yaml`
- link local dependencies with the `workspace:` protocol
- run build and test tasks across packages in parallel
- override vulnerable transitive packages inside `package.json`

## Example prompts
- Configure a workspace file covering applications and shared library directories.
- Add `lodash` strictly to `@org/my-app` using package filtering.
- Run tests across all workspaces and their dependents in parallel.

# pnpm Development

You are an expert in pnpm, the fast, disk space efficient package manager for JavaScript and TypeScript projects.

## Core Principles

- Always use pnpm (not npm or yarn) for package management
- Leverage pnpm's strict dependency resolution for better security
- Use the content-addressable store for disk space efficiency
- Maintain consistent lockfile (`pnpm-lock.yaml`)

## Installation and Setup

- Install pnpm globally: `npm install -g pnpm`
- Or use corepack: `corepack enable && corepack prepare pnpm@latest --activate`
- Specify pnpm version in `package.json`:
  ```json
  {
    "packageManager": "pnpm@9.0.0"
  }
  ```

## Workspace Configuration

Create `pnpm-workspace.yaml` for monorepo setup:

```yaml
packages:
  - 'apps/*'
  - 'packages/*'
  - 'tooling/*'
```

- Use glob patterns to define workspace package locations
- All matched directories with `package.json` become workspace packages

## Dependency Management

- Install dependencies: `pnpm install`
- Add dependencies to specific workspace:
  ```bash
  pnpm add lodash --filter @org/my-app
  pnpm add -D typescript --filter @org/my-lib
  ```
- Use workspace protocol for internal dependencies:
  ```json
  {
    "dependencies": {
      "@org/shared-utils": "workspace:*",
      "@org/ui": "workspace:^"
    }
  }
  ```
- Protocol options:
  - `workspace:*` - Any version, replaced with actual version on publish
  - `workspace:^` - Compatible versions
  - `workspace:~` - Patch versions only

## Filtering Commands

Run commands in specific packages:

```bash
pnpm --filter @org/my-app dev
pnpm --filter "./apps/*" build
pnpm --filter "...@org/my-lib" test  # Include dependents
pnpm --filter "@org/my-lib..." build  # Include dependencies
```

- Filter patterns:
  - `--filter <package-name>` - Specific package
  - `--filter "./path/*"` - By path
  - `--filter "...<pkg>"` - Package and its dependents
  - `--filter "<pkg>..."` - Package and its dependencies

## Scripts and Task Running

- Run scripts across workspaces:
  ```bash
  pnpm -r run build        # Run in all packages
  pnpm -r --parallel run dev  # Run in parallel
  pnpm -r --stream run test   # Stream output
  ```
- Define root-level scripts for common operations:
  ```json
  {
    "scripts": {
      "build": "pnpm -r run build",
      "dev": "pnpm --filter @org/web dev",
      "lint": "pnpm -r run lint",
      "test": "pnpm -r run test"
    }
  }
  ```

## Dependency Hoisting

Configure hoisting in `.npmrc`:

```ini
# Strict mode - no hoisting
hoist=false

# Selective hoisting
public-hoist-pattern[]=*eslint*
public-hoist-pattern[]=*prettier*

# Shamefully hoist everything (not recommended)
shamefully-hoist=true
```

- Prefer strict mode for better dependency isolation
- Use public hoisting for tools that need flat node_modules

## Peer Dependencies

Configure peer dependency handling in `.npmrc`:

```ini
auto-install-peers=true
strict-peer-dependencies=false
```

- Resolve peer dependency warnings appropriately
- Document required peer dependencies clearly
