Trigger when a user provides a .NET CI workflow file, a global.json, a Directory.Packages.props, a NuGet.config, a packages.lock.json, or a .csproj/.pubxml, asks whether their .NET build is reproducible and tamper-resistant, or wants to know whether their NuGet supply chain blocks a malicious or vulnerable dependency.

A .NET build is only tamper-resistant if the SDK is pinned, package versions are pinned and lock-verified, feeds are trusted and HTTPS, vulnerability scanning runs in CI, secrets never reach fork-PR code, and the build is reproducible. The review catches floating versions, missing lock files, untrusted or plain-HTTP feeds, soft-failure escape hatches on the build, secret exposure to <code>pull_request_target</code> and fork PRs, missing vulnerability scans, unpinned SDKs, and absent SBOM or provenance. It complements the generic <code>ci-test-pipeline-review</code> skill, which owns test-gating mechanics; this skill owns the .NET build and NuGet supply chain specifically.</p>\n<h2>Trigger conditions</h2>\n<ul>\n<li>A user provides a .NET CI workflow file (<code>.github/workflows/*.yml</code>, <code>.gitlab-ci.yml</code>, <code>azure-pipelines.yml</code>), a <code>global.json</code>, a <code>Directory.Packages.props</code>, a <code>NuGet.config</code>, a <code>packages.lock.json</code>, a <code>.csproj</code>, or a <code>.pubxml</code>.</li>\n<li>A user asks whether their .NET build is reproducible, tamper-resistant, or supply-chain hardened.</li>\n<li>A user wants to know whether their NuGet configuration blocks a malicious or vulnerable dependency.</li>\n</ul>\n<h2>Lean operating rules</h2>\n<ul>\n<li>CRITICAL — Treat secrets exposed to a fork-PR or <code>pull_request_target</code> build job (PR-author code runs with secrets in scope) as a stop-the-line exfiltration path.</li>\n<li>CRITICAL — Treat an untrusted or plain-HTTP (non-HTTPS) NuGet feed in <code>NuGet.config</code> as a tampering and credential-leak path.</li>\n<li>CRITICAL — Treat <code>continue-on-error: true</code> or <code>|| true</code> on the build or test step as a gate that verifies nothing.</li>\n<li>HIGH — Treat floating package versions (wildcard <code>*</code>, floating <code>1.2.*</code>) as a non-reproducible build that silently absorbs upstream changes.</li>\n<li>HIGH — Treat the absence of both <code>packages.lock.json</code> and Central Package Management (<code>Directory.Packages.props</code>) as no transitive-dependency pinning.</li>\n<li>HIGH — Treat a missing <code>dotnet list package --vulnerable</code> (or equivalent) vulnerability scan in CI as a build that ships known CVEs.</li>\n<li>HIGH — Treat an SDK not pinned via <code>global.json</code> as a non-reproducible toolchain.</li>\n<li>HIGH — Treat <code>dotnet restore</code> not run with <code>--locked-mode</code> when a lock file exists as a lock file that is decorative.</li>\n<li>HIGH — Treat a publish profile (<code>.pubxml</code>) that commits secrets as a credential leak.</li>\n<li>MEDIUM — Treat a missing SBOM or build provenance as an unverifiable release artifact.</li>\n<li>Never recommend disabling locked-mode to \"fix\" restore errors; never recommend pinning to a known-vulnerable version for stability; never recommend disabling a failing gate as the fix.</li>\n<li>Never request secrets, connection strings, tokens, feed credentials, or customer data.
