## What it does

The skill runs a three-layer pass over your solution. First, inventory: every `PackageReference` per project, with target frameworks and central package management awareness, pulled through the `get_nuget_packages` MCP tool — no network. Then staleness and known CVEs via the `dotnet` CLI. Last comes a license screen that flags packages which moved to commercial terms.

That last layer is the point. A plain `dotnet outdated --upgrade` can quietly shift your legal footing: MediatR from 13+, MassTransit from 9+, FluentAssertions from 8+, AutoMapper from 15+. The skill fires a LICENSE flag when a project sits on the free major and a naive update-all would cross the boundary.

You get one priority-ordered table: vulnerabilities first, license traps second, staleness last, each row with a recommended action. Steps two and three need a successful restore — fix a broken restore before auditing, or the version output is unreliable. Updates can then run through `/migrate` Flow C, one package at a time, with `dotnet build && dotnet test` between each.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill outdated -a claude-code
```

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- File: `~/.claude/skills/outdated/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/outdated/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill outdated -a codex
```

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- File: `.agents/skills/outdated/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill outdated -a cursor
```

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- File: `.cursor/skills/outdated/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install codewithmukesh/dotnet-claude-kit outdated
```

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- File: `.github/skills/outdated/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill outdated -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/codewithmukesh/dotnet-claude-kit --path skills/outdated
```

### Windsurf (Devin Desktop)

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- File: `.devin/skills/outdated/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill outdated -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/codewithmukesh/dotnet-claude-kit/tree/HEAD/skills/outdated/SKILL.md

## When to use it
- find vulnerable NuGet versions, transitive ones included
- catch a package crossing into a commercial license before you upgrade
- list every PackageReference across the solution's projects
- spot target frameworks that drifted apart between projects
- sort updates by priority instead of blind update-all

## Example prompts
- /outdated
- check my dependencies and show vulnerable packages
- run a NuGet package audit and check licenses

# /outdated

## What

A three-layer dependency health report:

1. **Inventory** — every `PackageReference` per project, with TFMs and central
   package management awareness, via the `get_nuget_packages` MCP tool (no
   network, token-cheap).
2. **Staleness + vulnerabilities** — current vs latest stable, and known CVEs,
   via the `dotnet` CLI.
3. **License screen** — flags packages that moved to commercial licenses so an
   innocent `dotnet outdated --upgrade` doesn't silently change your legal
   position.

The output is a single prioritized table — vulnerabilities first, license traps
second, staleness last — with a recommended action per row.

## When

- "check for outdated packages", "package audit", "dependency health"
- Before a .NET version upgrade (pairs with `/migrate` Flow B)
- After inheriting an unfamiliar codebase
- Dependabot/NuGet audit warnings appeared and you want the full picture
- Periodically on long-lived projects — quarterly is a good cadence

## How

**Step 1: Inventory (MCP, no network)**

```
get_nuget_packages()                          -- whole solution
get_nuget_packages(projectFilter: "Api")      -- or one project
```

Returns per-project `{Name, TargetFramework, Cpm, Packages: [{Id, Version}]}`.
Note `Cpm: true` — updates then belong in `Directory.Packages.props`, not the
csproj. Flag mixed TFMs across projects while you're here.

**Step 2: Staleness and vulnerabilities (CLI)**

```bash
dotnet list package --outdated
dotnet list package --vulnerable --include-transitive
```

Both need a successful restore first. If restore fails, fix that before
auditing — a broken lock state makes version output unreliable.

**Step 3: License screen**

Check the inventory against the known commercial moves (full rationale in
`knowledge/package-recommendations.md`):

| Package | Commercial from | Free alternative |
|---|---|---|
| MediatR | 13+ (Lucky Penny, RPL) | `Mediator` (martinothamar) — source-generated, MIT |
| MassTransit | 9+ (v8 Apache, patches end 2026 then EOL) | Wolverine 6.x, or stay on v8 short-term |
| FluentAssertions | 8+ (v7 stays Apache, frozen) | xUnit built-in `Assert` (kit default), Shouldly, AwesomeAssertions |
| AutoMapper | 15+ (Lucky Penny) | Manual mapping (kit default) or Mapperly (MIT) |
