## What it does

The skill targets projects managed strictly with pnpm and runs the `/check-npm` hardening gate before touching manifests. It cleans up unneeded direct dependencies, deduplicates versions across monorepos, and ranks packages by transitive closure. Non-trivial dependencies receive a label: Keep, Replace-with-Better, Replace-with-Internal, Remove, or Needs-user-review.

All lifecycle scripts remain blocked during routine execution through `--ignore-scripts`. Upgrades and additions also enforce a 72-hour npm release age check to prevent supply chain attacks, though `@grafana/*` packages are exempt from this waiting period.

It will stop immediately if a project runs on Yarn, npm, or Bun, because package manager migrations are out of scope. It is also not meant for Go modules or broad GitHub Actions workflow auditing.

## Requirements
- Works with: Grafana

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill audit-and-reduce-dependencies -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill audit-and-reduce-dependencies -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill audit-and-reduce-dependencies -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install grafana/skills audit-and-reduce-dependencies
```

2. **Manually: put the files in place**
- File: `.github/skills/audit-and-reduce-dependencies/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill audit-and-reduce-dependencies -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/grafana/skills --path skills/grafana-plugins/audit-and-reduce-dependencies
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill audit-and-reduce-dependencies -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/grafana/skills/tree/HEAD/skills/grafana-plugins/audit-and-reduce-dependencies/SKILL.md

## When to use it
- prune unused direct dependencies from `package.json`
- deduplicate package versions across pnpm workspaces
- inspect transitive lockfile impact before applying upgrades
- block packages published less than 72 hours ago

## Example prompts
- Audit pnpm dependencies and triage packages with Keep or Remove labels
- Find and remove unused direct dependencies in this workspace
- Run lockfile deduplication and check transitive closure

  Reduces JavaScript dependency footprint with pnpm while preserving lockfile,

# Audit and reduce dependencies

Reduce JavaScript dependency footprint. Use **pnpm only**. Preserve the lockfile, workspace layout, and dependency range style unless there is a concrete reason to change them.

For GitHub Actions workflow triage (action choice, permissions, pinning), use a dedicated workflow audit — not the reporting format below (workflow file + step only when the finding is **pnpm install policy**).

## Workflow

0. Hardening gate: run `/check-npm` (read-only). See [check-npm](../check-npm/SKILL.md).
1. Establish the baseline.
2. Remove unused direct dependencies.
3. Deduplicate direct dependency versions in monorepos.
4. Rank direct dependencies by transitive lockfile closure.
5. Use closure data to find low-risk minor/patch upgrades.
6. Use closure data to find trivial dependencies worth inlining.
7. Check e18e recommendations for replacements/removals.
8. Reinstall, verify, and report measured impact.

## Step 0: Hardening gate (`/check-npm`)

Run **`/check-npm`** before mutating manifests or lockfiles.

- If any check **FAIL**s: report the table and fix snippets; **do not weaken** `pnpm-workspace.yaml`, `.npmrc`, CI install flags, or Renovate age gates during cleanup.
- Do not paste full hardening config into this workflow — `/check-npm` owns version thresholds, script policy, git-dep protocols, and min release age.
- If the user only asked for hardening (not reduction), stop after `/check-npm` unless they also want cleanup.

**pnpm 11+:** script and release-age policy live in `pnpm-workspace.yaml`, not `.npmrc` or `package.json#pnpm` (pnpm 11 no longer reads the `package.json#pnpm` field). Verify each key against the installed pnpm major before suggesting config. Never add unsupported keys. Do not lower an existing `minimumReleaseAge` (or org equivalent) during cleanup.

## Dependency triage

For each non-trivial direct dependency (especially after Steps 4–7), assign one label:

| Label | Meaning |
|-------|---------|
| **Keep** | Required; worthwhile transitive cost; well maintained. |
| **Replace-with-Better** | Required; better-maintained or safer alternative exists. |
```
