extensibility skillA

extensibility is agent-read markdown (skill) from alo-exp/silver-bullet: This skill should be used when designing, planning, implementing, or reviewing any non-trivial change, or when the user asks to "add plugin point", "make this pluggable", "add hooks for X" — enforces open-closed design, plugin architectures, stable interfaces, and versioning so systems grow without breaking existing consumers.

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 alo-exp/silver-bullet/extensibility@v0.1.0
Exact content
mdr add alo-exp/silver-bullet/extensibility@sha256:f90efc9e228333b9

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.
