dotnet-deserialization-audit

dotnet-deserialization-audit is a skill for Codex from jinyimeng01/net-code-audit-skill-master. It costs 132 tokens per session (1,219 once invoked), scanned A, original, MulanPSL-2.0.

A security-audit workflow for finding unsafe object deserialization in .NET applications. Deserialization turns stored or received data back into program objects, and unsafe handling can let attackers control what the program creates or runs.

In plain words
What is it for?
Checking XML, JSON, remoting, SOAP, view-state, and binary serialization code, along with frameworks and libraries such as Json.NET, Telerik, DotNetNuke, and ServiceStack. It is used to identify and verify deserialization vulnerabilities.
Why use it?
It helps locate risky serializers, settings, and data paths that may allow attacks. The description covers both source-code review and authorized red-team laboratory testing.

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-deserialization-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.
