A lightweight RFC process for solo developers working with AI agents. Prevents premature complexity by forcing problem-first thinking before jumping to solutions. Use when the user is considering introducing new tools, libraries, architectural patterns, or infrastructure. When they're weighing a significant technical decision. Triggers on phrases like "should I add X", "I'm thinking about introducing Y", "is this overkill", "do I need X", "is X worth it", "/rfc", or when the user is about to adopt a tool/pattern without first articulating the problem it solves.
