dotnet-offsec-audit

dotnet-offsec-audit is a skill for Codex from jinyimeng01/net-code-audit-skill-master. It costs 170 tokens per session (1,654 once invoked), scanned A, original, MulanPSL-2.0.

A security-audit workflow for .NET applications and deployment files, including ASP.NET, WCF, IIS packages, and decompiled programs. It examines how requests, permissions, data, and configuration flow through an application.

In plain words
What is it for?
Auditing source code, compiled .NET files, or only a program’s `bin` directory. It produces a single reviewable `qualityreport.md` report covering routes, authentication, database and file operations, deserialization, server requests, and other checks.
Why use it?
It helps find security weaknesses across an entire .NET system, including access-control mistakes, unsafe data handling, exposed secrets, and common web vulnerabilities. It is described for authorized reviews and defensive checks.

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

dotnet-offsec-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 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/collect_dotnet_surface.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 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.
