detecting-memory-safety-bugs skillA

detecting-memory-safety-bugs is agent-read markdown (skill) from unboundcompute/security-agent-skills: Find memory-safety bugs in C/C++ and other unmanaged code - use-after-free, double-free, out-of-bounds read/write, uninitialized use, and NULL deref - by reasoning about object lifetime and buffer bounds along real code paths. Use on an authorized source target when a candidate catalog does NOT model these temporal/lifetime classes (most don't), so a keyword or sink scan will miss them; when reviewing allocators, parsers, buffer handling, or refcounting. Pairs the lifetime/bounds reasoning with .

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 unboundcompute/security-agent-skills/detecting-memory-safety-bugs@git:20260816.faa9c07
Exact content
mdr add unboundcompute/security-agent-skills/detecting-memory-safety-bugs@sha256:20a3447e01f84d4a

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.
