jacquard skillB

jacquard is agent-read markdown (skill) from jbwinters/jacquard-lang: Install and use Jacquard; write, check, run, format, hash, infer, test, and compile effect-typed, content-addressed .jac programs. Use for Jacquard surface syntax, capability manifests, handlers, discrete Dist models, Code values, Warp tests, canonical identity, replay, and native AOT builds..

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 jbwinters/jacquard-lang/jacquard@git:20260912.041230b
Exact content
mdr add jbwinters/jacquard-lang/jacquard@sha256:68139252599356b2

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.
