Version, validate, package, verify, recover, and hand off Agent Skill bundles across local folders, registries, platform uploads, and agent sessions. Use for MANIFEST.yaml, CHANGELOG.md, bundle hashes, stale evals, frontmatter portability, derived skill packages, or version identity that must survive filename changes and cross-platform movement. Do not use for ordinary Git version control that does not involve an Agent Skill bundle. Compatible with the agentskills.io open standard.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Skill Provenance ## The Problem This Solves Skill projects move between sessions, surfaces (Chat, IDE, CLI, Cowork), platforms (Claude, Gemini CLI, Codex, Copilot), and local storage (Obsidian, working directories, git repos). Version identity gets lost when it lives only in filenames. A file renamed from `SKILL_v4.md` to `SKILL_v5.md` with no internal record of what changed creates ambiguity. This skill establishes three conventions that prevent that: 1. Version identity lives inside files when their format allows it, and always in the manifest. 2. A recent changelog travels with the skill bundle, while longer history can live in the source repo. 3. A manifest lists every file in the bundle, and verification fails on unlisted files, so any session can verify completeness. ## What Gets Versioned A skill bundle is a SKILL.md plus all associated files. Typical contents: - SKILL.md (the skill definition) - evals.json (evaluation suite) - Generation scripts (e.g., generate.js, generate.py) - Output artifacts (.docx, .pdf) produced by evals or real use - Handoff notes - Source material provided by the user (tracked but not versioned) …

How to install
mdr add snapsynapse/skill-provenance/skill-provenance@sha256:d83d2ad7a3065907The line at the top of this page pins the label v26, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
