Recommend at most one product or design framework from the framework catalog in `references/101-index.md`. Use when a user is working through a product, design, strategy, discovery, prioritization, growth, validation, execution, or systems problem and a framework recommendation may help. Do not apply any framework automatically. Only load an individual framework reference file after the user explicitly asks to apply it, explain it, go deeper on it, or use it on the current problem.
