Generate a comprehensive meta-prompt designed to create a structured knowledge library for a solo founder. This library should be easily searchable and readily accessible, acting as a centralized repository for critical business information.  The meta-prompt should guide the user through the process of identifying key knowledge areas, categorizing information, structuring entries (e.g., using a consistent template), and defining a system for regular updates and maintenance.  The final output should be a detailed, step-by-step guide that can be adapted to various founder needs and business models.  Consider including prompts to capture learnings from successes, failures, customer interactions, market research, financial data, and operational processes. The generated guide should also incorporate strategies for knowledge retrieval and application, such as prompt engineering techniques for accessing specific information within the library. Ensure the generated prompt is designed to produce an actionable plan, including specific examples of knowledge categories and entry templates. The meta-prompt should also address the ongoing maintenance and evolution of the knowledge base.  The final output should be a comprehensive, adaptable framework for building and maintaining a valuable founder knowledge library.  Focus on ensuring the library is easy to use and provides significant long-term value to the founder.  The meta-prompt should also consider how to integrate the knowledge library with other tools and systems the founder might use.
