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
# SEO On-Page: Page Metadata Orchestrates the complete metadata lifecycle. It owns scope, routing, implementation, validation, and delivery; specialist skills own their individual writing and tag rules. **When invoking**: On first use, briefly state the scope and which specialist skills are needed.

How to install
mdr add kostja94/marketing-skills/page-metadata@sha256:14e82760d9c09ea7The line at the top of this page pins the label v2.0.0, 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.
