nuget-audit

nuget-audit is a skill for Claude Code, Codex from cwoodruff/dotnet-claude-code-kit. It costs 40 tokens per session (298 once invoked), scanned A, a copy of nuget-audit, MIT.

A report-based check of NuGet packages, which are reusable software components used in .NET projects. It looks for security weaknesses, discontinued packages, and newer available versions across a solution, including indirect dependencies.

In plain words
What is it for?
Use it to inspect restored .NET dependencies, list vulnerable, deprecated, or outdated packages, assess whether vulnerable code is used, and propose upgrade batches for approval.
Why use it?
It gives developers a structured view of package risks and upgrade needs instead of relying on scattered warnings. It also helps distinguish urgent security issues from routine version updates and possible breaking changes.

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

nuget-audit 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 5d 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.

What it actually says

NuGet Dependency Audit

  1. Restore first so metadata is current: dotnet restore
  2. Gather three views of the solution:
    • dotnet list package --vulnerable --include-transitive
    • dotnet list package --deprecated
    • dotnet list package --outdated
  3. Produce a report table: Package | Current | Status (vulnerable/deprecated/outdated) | Severity/Advisory | Recommended version | Breaking-change risk.
  4. Prioritize: vulnerabilities (by severity) → deprecated → major-version-behind → minor/patch.
  5. For each vulnerable package, state whether the vulnerable code path is plausibly reachable from this codebase (grep for usage) — don't just list CVEs.
  6. Propose an upgrade plan in safe batches (patch/minor first). Only run dotnet add package upgrades the user approves, one batch at a time, building and running tests between batches.
  7. Flag transitive-only vulnerabilities separately and recommend either a direct pin or upstream bump.
Changes

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.
