Drive Vercel's `deepsec` agent-powered vulnerability scanner end-to-end: installing the `.deepsec/` workspace, bootstrapping `INFO.md`, running cost-aware `scan` / `process` / `triage` / `revalidate` / `export` passes, gating PRs with `process --diff`, writing custom matchers, and triaging findings. Use whenever the user mentions deepsec, asks an agent to scan a repo for vulnerabilities, runs into `pnpm deepsec` / `bunx deepsec` commands, wants a CI-based PR security review, sees a `.deepsec/` directory, or asks about `INFO.md` / matchers / `process --diff` / `revalidate`, even when the tool name is not spoken. Deepsec scans are expensive (a single full scan can cost hundreds to tens of thousands of dollars) so the skill exists in part to keep the user from getting surprised.

Reviews a NuGet/NuGet.Client pull request like a senior maintainer — reviews in an isolated workspace by default, or against the reviewer's existing clone (self-review / local changes), builds and tests the affected projects, traces changes across files, and returns high-signal, severity-tagged findings with a merge verdict. Invoke explicitly with a PR number or branch.

Enable C# nullable reference types on files that still have `#nullable disable` in the NuGet.Client codebase. Use this skill whenever the user asks to enable nullable, migrate nullable, remove `#nullable disable`, annotate nullability, or fix nullable warnings for any NuGet project or file. Also trigger when the user mentions a GitHub issue about nullable enablement, references PublicAPI.Shipped.txt annotation updates, or says things like "let's do nullable on X" or "enable nullable for these files."
