An individual developed a "second brain" system using an LLM agent that interacts with a personal knowledge base stored in Markdown files. The primary challenge encountered was the LLM agent's tendency to forget or stop updating information, which could not be resolved by simply refining instructions. The solution involved shifting critical enforcement tasks, such as saving context and updating indexes, from the LLM's instructions to external hooks within the agent's harness. This ensures that essential operations are guaranteed to run, while the LLM focuses on its strengths in interpreting and categorizing information. AI
