functional-core-imperative-shell skillA

functional-core-imperative-shell is agent-read markdown (skill) from ed3dai/ed3d-plugins: Use when writing or refactoring code, before creating files - enforces separation of pure business logic (Functional Core) from side effects (Imperative Shell) using FCIS pattern with mandatory file classification.

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 ed3dai/ed3d-plugins/functional-core-imperative-shell@git:20260218.0673566
Exact content
mdr add ed3dai/ed3d-plugins/functional-core-imperative-shell@sha256:ac1000351b2dcee5

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.
