dev-security-audit skillB

dev-security-audit is agent-read markdown (skill) from sd0xdev/sd0x-harness: Comprehensive developer workstation security audit — scans for exposed credentials, compromised application data, persistence mechanisms, and supply chain attack indicators. Use this skill whenever the user suspects their machine may be compromised, wants to check for exposed secrets, asks about supply chain attacks, or wants a full security audit of their development environment. Also triggers on: 'am I compromised', 'check my security', 'scan for leaked keys', 'credential audit', 'supply chain.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add sd0xdev/sd0x-harness/dev-security-audit@git:20260325.c918402
Exact content
mdr add sd0xdev/sd0x-harness/dev-security-audit@sha256:e56e28eb6ebceb98

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
