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
# newsletter-platform-stinger Start with [README.md](README.md) for the workflow map and detailed references. The newsletter channel playbook for product builders and founders who want to build an audience alongside a SaaS or content product. This skill encodes the platform selection decision tree, the embedded-signup integration cookbook, deliverability fundamentals per platform, the monetization option map, and the migration checklist.

How to install
mdr add legioncodeinc/vibe-coding-tools/newsletter-platform-stinger@sha256:e6043c1e4a9fada4The line at the top of this page pins the label git:20261015.ad09fa4, 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.
