CoolDeep AI Digest

The newsletter begins with promotional content for sponsoring the CoolDeep AI Newsletter and a HubSpot Academy digital marketing certification offer, followed by a brief note about an upcoming AI IPO wave and a MarketBeat report on AI stocks, plus an invitation to join CoolDeep AI daily alerts. The core of the message is a personal reflection by the author on discovering Claude’s ‘Skills’ feature after feeling like a beginner despite covering AI daily. The author explains that Claude Skills transform the chatbot from a conversational tool into a workflow‑automation agent by encoding standard operating procedures (SOPs) into reusable, instruction‑based packages. A Skill is essentially a structured skill.md file that defines a name, description, and detailed workflow for Claude to follow consistently, much like training an employee who never forgets or deviates. The article walks readers through creating a Skill without coding: in Claude Cowork, navigate to Customize → Skills → Add → Create with Claude, then describe the desired workflow in plain language (e.g., writing Instagram Reel scripts with specific hooks, length, and options). Claude automatically generates test cases, runs them in parallel, shows evaluation results, and highlights any failures, allowing the user to refine the Skill before finalizing it. Once satisfied, the user tells Claude to package the Skill, producing a ready‑to‑use skill.md file that can be invoked repeatedly to automate tasks exactly as specified. By emphasizing that no technical background is required, the author positions Skills as a practical way to embed personal or business processes into Claude, ensuring reliable, repeatable execution of SOPs, business logic, or routine tasks. The piece concludes by encouraging readers to explore the Skills section, build their own, and leverage Claude as a true workflow partner rather than just a chat companion.
