open skillA
open is agent-read markdown (skill) from snapsynapse/skill-provenance: Verify a skill bundle's integrity when opening a project. Use when loading a skill project directory and you need to check file completeness, verify SHA-256 hashes against MANIFEST.yaml, detect stale files, review recent changes, or understand what state the bundle is in before starting work. Triggers on: "open this skill", "verify the bundle", "check what changed", "is everything up to date", "load this project"..
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 snapsynapse/skill-provenance/open@git:20260820.3ed2639mdr add snapsynapse/skill-provenance/open@sha256:8b80083e8c4c92c3Pin 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.
