According to God of Prompt on X, Anthropic released free, certificate-backed courses on building with Claude covering prompt engineering, tool use, retrieval augmented generation, and evaluations (source: God of Prompt). As reported by Anthropic’s course portal, the curriculum is created by Anthropic’s product and research teams and is available at anthropic.skilljar.com at no cost, offering structured learning paths and assessments for practitioners (source: Anthropic Skilljar). According to Anthropic’s course descriptions, the content emphasizes hands-on labs for Claude tool use, RAG system design patterns, and systematic evaluation workflows, enabling teams to accelerate prototyping and reduce integration risk for production LLM applications (source: Anthropic Skilljar). For businesses, the no-cost certification lowers training barriers for product, data, and developer teams, supports standardized prompt patterns, and can shorten time-to-value for Claude-based copilots and agents in customer support, analytics, and content automation (source: Anthropic Skilljar).
