detecting-race-conditions skillA

detecting-race-conditions is agent-read markdown (skill) from unboundcompute/security-agent-skills: Find concurrency and time-of-check/time-of-use bugs - TOCTOU, unsynchronized shared state, check-then-act, and atomicity violations - by reasoning about what state is shared, what can interleave, and where a window opens between a check and its use. Use on an authorized source target when the risk is ordering, not a single tainted value; when reviewing multithreaded code, shared caches/counters, filesystem checks, or "verify then act" sequences (balance checks, auth-then-use, dedup guards). Conf.

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-race-conditions@git:20260816.faa9c07
Exact content
mdr add unboundcompute/security-agent-skills/detecting-race-conditions@sha256:847e5e6b72561664

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.
