dotnet-auth-audit

dotnet-auth-audit is a skill for Codex from jinyimeng01/net-code-audit-skill-master. It costs 66 tokens per session (1,852 once invoked), scanned A, original, MulanPSL-2.0.

A security-audit workflow for authentication and authorization in .NET applications. Authentication checks who a user is; authorization checks what that user is allowed to do.

In plain words
What is it for?
Reviewing Forms Authentication, ASP.NET Core Identity, JWT, OAuth/OIDC, Windows authentication, membership systems, and custom authentication modules. It checks issues such as IDOR/BOLA/BFLA, where users access or perform actions outside their permissions.
Why use it?
It helps find login weaknesses and access-control errors where users can reach records, functions, or actions they should not. It also maps routes to their required protections and highlights bypass patterns.

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-auth-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 6d 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 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.
