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
# Developer Newsletter This skill helps you build and write newsletters that developers actually open, read, and look forward to receiving. Covers content strategy, writing, growth, and deliverability. --- ## Before You Start **Load your audience context first.** Read `.agents/developer-audience-context.md` to understand: - Who you're writing for (role, seniority, tech stack) - What content resonates (problems, interests) - Where else they consume content (to avoid duplicate effort) - Voice & tone (how casual/technical) If the context file doesn't exist, run the `developer-audience-context` skill first. --- ## Newsletter Strategy ### Define Your Newsletter Type | Type | Description | Example | |------|-------------|---------| | **Product updates** | Changelog, new features, tips | Vercel's updates | | **Curated links** | Best content from around the web | TLDR, Bytes | | **Original content** | Your own articles, tutorials | Cassidy Williams | | **Community digest** | What happened in your community | Dev community roundups | | **Educational series** | Teaching a topic over time | Course-style newsletters | …

How to install
mdr add jonathimer/devmarketing-skills/developer-newsletter@sha256:429dea0ff003f965The line at the top of this page pins the label v1.0.0, 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.
