reversible-system-change skillA

reversible-system-change is agent-read markdown (skill) from wheakerd/axiom: Plan, rehearse, or execute persistent system changes with verified rollback and postconditions. Use for an install, upgrade, deployment, migration, destructive retention action, active-version promotion, or explicit machine-credential lifecycle inventory, plan, activation, or retirement with rollback, data, service, or activation risk. Plans and non-mutating workflow rehearsals stay read-only; isolated restore rehearsals require exact rehearsal-write authority. Pair with confirm-external-action .

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 wheakerd/axiom/reversible-system-change@git:20260910.6719a83
Exact content
mdr add wheakerd/axiom/reversible-system-change@sha256:08497c236641de9d

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.
