outdated

A dependency health report for .NET projects. It lists installed NuGet packages, checks for newer or vulnerable versions, and flags packages whose licenses may have become commercial.

In plain words
What is it for?
Use it when auditing a .NET solution, preparing for a framework upgrade, reviewing an inherited codebase, or investigating NuGet and Dependabot warnings.
Why use it?
It brings version problems, security risks, and licensing concerns into one prioritised report before an upgrade causes surprises.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

outdated scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/outdated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 License screen — flags packages that moved to commercial licenses so an innocent dotnet outdated --upgrade doesn't silently change your legal position.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  • "check for outdated packages", "package audit", "dependency health"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)

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)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

outdated is a skill published in the GitHub repository codewithmukesh/dotnet-claude-kit (684 stars, last pushed 25d ago), licensed MIT. It adds 98 tokens to every session and 1,259 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
