principle-separate-before-serializing-shared-state skillA
principle-separate-before-serializing-shared-state is agent-read markdown (skill) from michael-denyer/pstack-claude: Apply when concurrent actors might write to the same file, branch, key, or state object. Eliminate the sharing first; serialize structurally only when one shared writer is a real invariant..
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 michael-denyer/pstack-claude/principle-separate-before-serializing-shared-state@git:20260907.ebb8c27mdr add michael-denyer/pstack-claude/principle-separate-before-serializing-shared-state@sha256:ca798978d31ffec6Pin 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.
