simba skillA
simba is agent-read markdown (skill) from ahoo-wang/skills: Guide for using the Simba distributed mutex and leader-election library in JVM projects. Use when creating distributed locks, implementing leader-only work, configuring Simba backends (JDBC/MySQL, Redis, Zookeeper), writing MutexContender or AbstractScheduler subclasses, using SimbaLocker, integrating Simba with Spring Boot, choosing backends, or tuning TTL/transition settings. For test-focused work, use the simba-testing skill as well..
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
mdr add ahoo-wang/skills/simba@git:20260821.ec5fc28mdr add ahoo-wang/skills/simba@sha256:9d9e1a2011759942Pin 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.
