Generates platform-specific social media copy from album themes, track concepts, and lyrics. Use when promo/ templates need to be populated before release.
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
# Promo Writer Skill Generate social media copy for album promotion across Twitter/X, Instagram, TikTok, Facebook, and YouTube. Produces native-feeling content for each platform from album context — themes, track concepts, and streaming lyrics. ## Purpose Populate the `promo/` directory with platform-specific copy ready for review. Each platform gets content shaped to its format, tone, and conventions — not the same text cross-posted everywhere. ## When to Use - After track concepts and lyrics are written (need material to pull from) - Before release — generate copy to fill promo/ templates - User says "write promo copy", "create social media posts", or "fill in the promo templates" - When promo/ files exist but are still template placeholders ## Position in Workflow ``` Lyrics Written → Promo Videos (optional) → **[Promo Writer]** → [Promo Review] → Release ``` Between content completion and promo-reviewer. The promo-reviewer polishes what this skill generates. ## Supporting Files - **[copy-formulas.md](copy-formulas.md)** — Hook formulas, CTA templates, post structures, hashtag recipes …

How to install
mdr add bitwize-music-studio/claude-ai-music-skills/promo-writer@sha256:d58af9db1bdb897aThe line at the top of this page pins the label git:20260529.eaf4945, 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.
