principle-type-system-discipline skillA

principle-type-system-discipline is agent-read markdown (skill) from cursor/plugins: Apply when designing types, reviewing a function signature, or writing code in any statically-typed language. Make illegal states unrepresentable, brand semantic primitives, parse external data at boundaries, refuse to lie to the compiler, exhaust variants, derive from authoritative schemas..

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 cursor/plugins/principle-type-system-discipline@git:20260908.d7cde2b
Exact content
mdr add cursor/plugins/principle-type-system-discipline@sha256:c83da8031ffb4c86

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.
