Lessons from Building a Local Memory Layer for Coding Agents
kevinsonly1 · reddit · 2026-07-16
The author shares a local-first, git-native memory layer built for Claude Code, Cursor, and Copilot (via MCP), summarizing design lessons from months of real-world usage.
Key takeaways include:
- Memory saving must be dead simple, or agents won't write proactively. Early schemas were too complex, so they narrowed it down to three types: fact / decision / constraint, using tags instead of fine-grained categories.
- Don't let memory extraction cost more tokens than the session itself. Instead of running LLM extraction on every turn or git hook, they let agents save explicitly. Recall uses BM25 + metadata reranking, keeping outputs short with pagination hints.
- Memory should live where code is reviewed. Team memory goes into the repo's .fluree-memory/ directory, while personal memory stays local. Through git diff / blame, bad memories can be spotted just like bad code.
- Secret leakage must be prevented. Common credential patterns are scanned and automatically redacted on write.
The author also asks how others manage persistent agent context: sticking with CLAUDE.md, vector DBs, or custom solutions.
