# dependency-upgrade

Upgrades dependencies without the usual risk: sets a cooldown on new versions, blocks postinstall scripts, and rolls out changes in stages.

## What it does

The skill covers dependency work across npm, Bun, pnpm, Yarn and Deno. It writes security configs, plans incremental upgrade paths, and adds lockfile validation. Two modes: interactive, where you answer a few questions and get a config tailored to the project, and default, which applies recommended settings right away — a 7-day cooldown, all scripts blocked, frozen-lockfile, `lockfile-lint`, and Dependabot with a delay.

The core rule is simple: don't install fresh versions immediately. A newly published package can carry malicious code and get pulled within days. So the skill configures `min-release-age`, disables `postinstall` and `preinstall` (the most common supply chain vector), and pushes `npm ci` plus `--frozen-lockfile` in CI. For pre-install checks it offers `npq` and the Socket CLI.

One thing to watch: some settings depend on your package manager version. `trustPolicy: no-downgrade` in pnpm needs 10.21+, and script blocking is already on by default in pnpm and Bun, so trusted packages have to be listed by hand. If your project relies on a fast-moving package like `typescript` or `esbuild`, add it to the cooldown exclusions or the build will stall.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill dependency-upgrade -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill dependency-upgrade -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill dependency-upgrade -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install secondsky/claude-skills dependency-upgrade
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill dependency-upgrade -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/secondsky/claude-skills --path plugins/dependency-upgrade/skills/dependency-upgrade
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill dependency-upgrade -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/secondsky/claude-skills/tree/HEAD/plugins/dependency-upgrade/skills/dependency-upgrade/SKILL.md

## When to use it
- set a cooldown on newly published packages
- block postinstall scripts across a repo
- untangle a peer dependency conflict
- plan a major framework version jump
- add lockfile validation to CI

## Example prompts
- Set up secure dependency upgrades for this project
- Check the lockfile and add lockfile-lint to CI
- Plan an upgrade to the next major React version with tests between steps

# Dependency Upgrade

Manage dependency upgrades with supply chain security, compatibility analysis, staged rollout, and comprehensive testing across all major package managers.

## When to Use This Skill

- Upgrading major framework or library versions
- Configuring supply chain attack prevention (cooldown, script blocking, lockfile hardening)
- Setting up secure package manager configuration
- Resolving dependency conflicts or peer dependency issues
- Planning incremental upgrade paths with testing
- Automating dependency updates with Renovate, Dependabot, or Snyk
- Auditing dependencies for vulnerabilities
- Setting up CI/CD dependency security workflows

## Two Modes of Operation

**Interactive** — Walk through setup questions to generate tailored config. Use for fresh setup.

**Default** — Apply recommended defaults immediately: 7-day cooldown, block all scripts, frozen-lockfile, lockfile-lint, Dependabot with cooldown. Customization optional.

## Interactive Setup Flow

When the user wants tailored configuration, walk through these decisions. Skip this section entirely if using default mode.

### Tier 1: Required Decisions

Always ask these 3 questions before generating any config:

**1. Package Manager**

"Which package manager does this project use?"

| Answer | Generates |
|--------|-----------|
| npm | `.npmrc` |
| Bun | `bunfig.toml` |
| pnpm | `pnpm-workspace.yaml` |
| Yarn | `.yarnrc.yml` |
| Deno | `deno.json` config |

**2. Cooldown Period**

"How many days should newly published packages age before install? This prevents supply chain attacks where malicious packages are discovered and unpublished within days."

| Option | Days | Use Case |
|--------|------|----------|
| Aggressive | 3 | Catches most typosquatting |
| Recommended | 7 | Good balance for most projects |
| Conservative | 14 | Critical/production systems |
| Paranoid | 21 | Matches Snyk's built-in default |
| Custom | N | User specifies |

**3. Post-Install Script Policy**

"How should lifecycle scripts (postinstall, preinstall) be handled? These are the #1 attack vector for supply chain attacks."

| Option | Behavior |
|--------|----------|
| Block all (recommended) | `--ignore-scripts` + allow-git=none |
```
