Upgrade or synchronize Agent Skills, or determine a Skill's source and ownership across runtimes and roots. Use only for those lifecycle decisions. Do not use for installation, creation or editing, validation, inventory, usage statistics, general audits, cleanup, packaging, publishing, or ordinary file and package work.
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 Lifecycle Manager
Orchestrate skill work as one evidence-backed lifecycle. Keep source,
installation, and ownership separate so an update to one copy does not silently
overwrite another.
## Invocation Boundary
Use this skill only to upgrade Skills, synchronize Skill copies, determine a
Skill's source, or determine who owns and may update a Skill. For every other
Skill-related request, continue without this skill and use the narrower
applicable workflow.
## Core Contract
Maintain three boundaries throughout the task:
- **Source**: where the skill came from, such as GitHub, skills.sh, a Skill Hub
checkout, or a local repository.
- **Install**: where a runtime loads the active skill, such as a global user
root or project root.
- **Ownership**: whether the path is user-maintained, project-maintained, or
system/plugin-managed.
- **Runtime**: which loader owns the active copy, such as Codex, Claude Code,
an Agent Skills-compatible host, or more than one runtime.
Do not treat a Skill Hub checkout, `_repos` source, plugin cache, and global
install as interchangeable even when their skill names match.

The line at the top of this page pins the label git:20260919.e8b19bf, 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.
