Show HN: Mem – deterministic CLI memory sidecar for dev workflows
arthurborgesdev Thursday, February 12, 2026
I built mem, a deterministic CLI-first memory sidecar for dev workflows.
It stores append-only JSONL events (commits, agent runs, decisions) and deterministically compacts to state.json + MEMORY.md so humans/agents can recover context quickly.
Design constraints: - local files only - no network access at runtime - no daemon - POSIX sh + jq tooling
I’d love feedback on: 1) data model / event schema 2) compaction strategy 3) where this breaks in real team workflows
Summary
The article discusses the development of MEM, an open-source memory management library for C/C++ applications. MEM aims to provide a lightweight and efficient solution for dynamic memory allocation, with features like automatic memory reclamation and support for custom allocators.
