Designing Memory for a Minimal Rust Coding Agent, Without a Vector Store (opens in new tab)

A design walkthrough for the memory subsystem I contributed to zerostack, a minimalist Rust coding agent. Surveys what Claude Code, oh-my-pi, memsearch, and opencode-agent-memory do, explains why vectors were declined, and lands on plain-Markdown memory with a search that catches up to vector retrieval for this use case.
