Follow this process for every call. Do not skip steps. Do not pass the user's raw message. - -### Why Rewriting Matters - -The search engine matches your query against stored memories using vector similarity and keyword overlap. Stored memories are factual third-person statements like "User is a data scientist based in Berlin" or "User decided to adopt weekly sprint reviews because biweekly was too slow." The user's conversational message contains noise words ("can you", "I was wondering", "help me") that dilute the signal and match nothing useful in the memory store. - -### The Process - -For every memory_search call, follow these four steps: - -**Step 1. Name your target.** -Before writing the query, identify what category of stored memory you expect to find. This prevents aimless retrieval. - -**Step 2. Extract signal words.** -Pull out every proper noun, technical term, domain concept, and specific detail from the user's message. Drop conversational framing, questions, pronouns, and filler. - -**Step 3. Bridge to storage language.** -Think about how the memory was written when it was stored. Memories are third-person factual statements. They contain words like "User", "configured", "decided", "prefers", "rule", "team", "project", "based in", "works at". Add the relevant category term if it helps: "identity", "decision", "rule", "preference", "configuration", "relationship". - -**Step 4. Compose a keyword query.** -Join the terms from steps 2 and 3 into a string of 3 to 6 keywords. No question marks. No pronouns. No sentence structure. The query should read like index terms, not natural language. - -### Worked Examples - -Each example shows the full reasoning chain.
