Set up shared product context once
The repo tells you to capture your product, ICP (ideal customer profile), positioning, customer language, and brand voice in .agents/product-marketing.md. It also recognizes the older .claude/product-marketing.md and product-marketing-context.md files. Related skills read this context first so their output fits your product and customers.
