| description | Dependency health report for .NET solutions: outdated NuGet packages, vulnerable versions, and commercial-license traps (MediatR, MassTransit, FluentAssertions, AutoMapper) — powered by the get_nuget_packages MCP tool. Invoke when: "outdated packages", "check dependencies", "stale packages", "package audit", "dependency health", "are my packages up to date", "license check", "vulnerable packages", "nuget audit".

/outdated
What
A three-layer dependency health report:
- Inventory — every
PackageReference per project, with TFMs and central
package management awareness, via the get_nuget_packages MCP tool (no
network, token-cheap).
- Staleness + vulnerabilities — current vs latest stable, and known CVEs,
via the
dotnet CLI.
- 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dotnet outdated --upgrade doesn't silently change your legal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- "check for outdated packages", "package audit", "dependency health"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dotnet list package --outdated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) |
A license flag fires when the project is on the free major and a naive
"update all" would cross the boundary — that is the trap this step exists for.
Step 4: Report
One table, priority-ordered:
| Priority | Meaning | Action |
|---|
| VULNERABLE | Known CVE in current version | Update now, test, deploy |
| LICENSE | Next major crosses a commercial boundary | Pin below boundary or plan migration |
| MAJOR | Behind a major (breaking changes likely) | One at a time, release notes first |
| MINOR/PATCH | Routine drift | Batch patches; minors one at a time |
Step 5: Act (optional)
Offer to execute updates via /migrate Flow C — one package at a time,
dotnet build && dotnet test between each. Never batch major updates:
batched failures are unattributable.
MCP Tools Used
get_nuget_packages — inventory, CPM detection, TFM auditget_diagnostics — verify the solution still compiles clean after updates
Example
User: /outdated
Claude: Inventorying packages (get_nuget_packages)...
3 projects, CPM enabled (Directory.Packages.props), all net10.0.
Checking versions and CVEs...
| Package | Current | Latest | Priority | Action |
|--------------------------|---------|---------|------------|---------------------------------|
| System.Text.Json (trans.)| 10.0.2 | 10.0.10 | VULNERABLE | Update now (CVE-2026-XXXX) |
| MassTransit | 8.3.0 | 9.1.2 | LICENSE | v9 is commercial. Stay on v8 |
| | | | | (EOL end 2026) or plan Wolverine|
| Serilog.AspNetCore | 9.0.0 | 10.0.0 | MAJOR | Update alone, check sink compat |
| FluentValidation | 12.0.1 | 12.1.1 | PATCH | Batch with other patches |
1 vulnerability, 1 license trap, 1 major, 1 patch.
