secure-software-engineering skillA

secure-software-engineering is agent-read markdown (skill) from magnus919/agent-skills: Use when designing or implementing software securely: define security requirements, threat-model a feature, choose secure defaults, design authentication and authorization, handle untrusted data and secrets, evaluate dependencies, design multi-tenant trust boundaries, or review security-sensitive changes. Use for prevention during requirements, design, implementation, and review; not for post-build security assessments or scanning an existing codebase..

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 magnus919/agent-skills/secure-software-engineering@git:20260821.016be9c
Exact content
mdr add magnus919/agent-skills/secure-software-engineering@sha256:11bfc141a9577ad0

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.
