javascript skillA

javascript is agent-read markdown (skill) from wewpellex21/code-sensei: JavaScript essentials for vibecoders. Activated when Claude works with .js/.mjs/.jsx/.ts files. Covers the language concepts most commonly encountered during vibecoding..

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 wewpellex21/code-sensei/javascript@git:20260207.d76e1ca
Exact content
mdr add wewpellex21/code-sensei/javascript@sha256:9a4b559a1c78e846

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.
