The post describes the development of a “Mind System,” a sophisticated operating system designed to improve knowledge management for AI developers. Frustrated by the AI’s inability to retain context from previous sessions, the author initially organized notes in markdown but faced retrieval challenges as the volume grew. The solution involved creating a structured knowledge base with YAML frontmatter, a command-line interface for governance, and a multi-tier architecture to categorize documents. The system includes automated maintenance cycles to combat decay and provides a feedback loop for continuous improvement. Ultimately, the system aims to ensure that AI operates consistently and effectively within defined boundaries.
