obsidian-backup skillA

obsidian-backup is agent-read markdown (skill) from tonydzi/second-brain-starter-kit: Run the vault data-safety runbook: 3-2-1 backup, the never-deleted originals archive, the schedulers that keep it running, and the restore or new-machine migration procedure. Verifies by reading state rather than trusting exit codes. Triggers: "make a backup", "verify the backup", "the backup looks broken", "restore the vault"..

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 tonydzi/second-brain-starter-kit/obsidian-backup@git:20260908.2ec1bf8
Exact content
mdr add tonydzi/second-brain-starter-kit/obsidian-backup@sha256:d5607f0a42f31185

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.
