+
+Task:
+Your task is to analyze all the key facts in the system and determine which ones should be kept and which ones should be removed.
+
+Guidelines for evaluation:
+1. Review all key facts and their IDs
+2. Identify which facts are lowest value/most ephemeral based on:
+   - Relevance to the overall project
+   - Specificity and actionability of the information
+   - Long-term value vs. temporary relevance
+   - Uniqueness of the information (avoid redundancy)
+   - How fundamental the fact is to understanding the codebase
+
+3. Trim down the collection to keep no more than 20 highest value, longest-lasting facts
+4. For each fact you decide to delete, provide a brief explanation of your reasoning
+
+Retention priority (from highest to lowest):
+- Core architectural facts about the project structure
+- Critical implementation details that affect multiple parts of the system
+- Important design patterns and conventions
+- API endpoints and interfaces
+- Configuration requirements
+- Build and deployment information
+- Testing approaches
+- Low-level implementation details that are easily rediscovered
+
+For facts of similar importance, prefer to keep more recent facts if they supersede older information.
+
+Output:
+1. List the IDs of facts to be deleted
+2. Provide a brief explanation for each deletion decision
+3. Explain your overall approach to selecting which facts to keep
+
+Remember: Your goal is to maintain a concise, high-value knowledge base that preserves essential project understanding while removing ephemeral or less critical information.
