Oh Memories, Where'd You Go

Engram, a memory product built on Weaviate's vector search technology, is designed to enhance the workflow of a product manager by structuring memory around semantic categories, thus providing context that a traditional memory system like MEMORY.md cannot. The author, who integrated Engram into their workflow with Claude Code, observed that while Engram offers significant advantages in decision archaeology by recalling reasoning chains and document intent more efficiently, it encountered challenges in planning sessions where previous contexts were ignored. Engram's integration revealed silent failures in tasks perceived as forward-looking and added noticeable overhead to sessions. The solution involved developing deterministic retrieval triggers to ensure relevant memories are automatically injected at specific points, improving session fluidity without relying on Claude's discretion. Despite the initial expectation of proving Engram's value, the exercise highlighted specific conditions and mechanics that influence its efficacy, providing valuable insights for improvement as it moves towards general availability.
