AI-assisted summary based on the listed source.

Hi HN, I built HL-Mem (GitHub link below, Apache-2.0), a long-term memory sidecar for AI agents. It sits next to your agent (Claude Code, Hermes, anything speaking MCP stdio) and gives it durable, queryable memory across sessions. The core idea is boring and old - treat extracted facts as first-class records with...

This approach enables AI agents to maintain accurate and evidence-grounded knowledge over time, improving reliability and context retention. It addresses limitations in current memory systems that rely on summarization and hope for the best.
