Open Source CMO Claude skill

Paul Syng has released a free “Open Source CMO” skill for Claude, packaging classic marketing frameworks into a reusable artificial intelligence workflow. (x.com) Anthropic describes a Claude skill as a folder of instructions that teaches Claude how to handle a specific task or workflow, with a required `SKILL.md` file and optional scripts, references, and assets. Anthropic says skills are meant for repeatable work and can be built, tested, and shared with a community. (anthropic.com) Syng has spent more than two decades in brand consulting and business transformation, and his site says he has helped clients close more than $2 billion in top-line sales. His recent writing argues that marketing frameworks only work when they are tied to business outcomes such as market share, margins, and customer lifetime value. (paulsyng.com, paulsyng.com) That framing fits the pitch around this skill. Syng’s post presents it as a way to make Claude use the Four Ps of marketing — product, price, place, and promotion — while “speaking” in the financial terms that chief financial officers and chief executive officers use. (x.com, paulsyng.com) The timing lines up with Anthropic’s broader push to turn Claude into a work system, not just a chat window. Anthropic said in February 2026 that Skills, Claude in Chrome, and Claude Cowork had launched in research preview, and its current product pages list Skills alongside Claude Code, Cowork, and enterprise plans. (anthropic.com, anthropic.com) Skills are spreading beyond software engineering into business functions. GitHub repositories and marketplaces now list reusable Claude skills for marketing, finance, product management, and founder workflows, all built around the same idea: store expert instructions once, then call them on demand. (github.com, github.com, skillsmd.co) That growth has also produced a trust problem. Security researchers at OpenSource Malware said this month that attackers used fake Claude skills themed around cryptocurrency trading to distribute information-stealing malware, turning the emerging skills ecosystem into a supply-chain target. (opensourcemalware.com) Syng’s release lands in that wider rush to turn management playbooks into portable artificial intelligence instructions. The bet is that a marketing framework from the 1960s can still be useful in 2026 if it is structured well enough for Claude to run it repeatedly. (paulsyng.com, anthropic.com)
