principle-redesign-from-first-principles skillA
principle-redesign-from-first-principles is agent-read markdown (skill) from backnotprop/pstack: Apply when integrating a new requirement into an existing design. Redesign as if the requirement had been a foundational assumption from day one, instead of bolting it on..
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
mdr add backnotprop/pstack/principle-redesign-from-first-principles@git:20260914.55bfdc2mdr add backnotprop/pstack/principle-redesign-from-first-principles@sha256:a1c7fd0a96b40e12Pin 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.
