A developer found that SQLite's FTS5 full-text search was a more effective tool than vector search for their coding agent's memory. While vector search excels at semantic similarity for prose, FTS5 is better suited for the keyword-dense, structured data like stack traces and API responses commonly encountered in coding agent tasks. The author demonstrated a simple FTS5 implementation using Python's `sqlite3` module, highlighting its efficiency and out-of-the-box relevance scoring without the need for embedding models or separate vector databases.
