newsletter-writer skillA

newsletter-writer is agent-read markdown (skill) from naveedharri/benai-skills: Write newsletters for Ben Van Sprundel from any source — YouTube videos, article URLs, or raw ideas/insights. Use this skill EVERY TIME the user says they want to write a newsletter, create a newsletter, draft a newsletter, turn something into a newsletter, repurpose content for a newsletter, write an email issue, or any variation of newsletter writing. Also trigger when the user shares a YouTube URL or article URL alongside any mention of email or newsletter content. This is a STEP-BY-STEP, int.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
