What users praise

  • • Persistent memory across sessions via flat-file Markdown architecture — no context loss.
  • • Hybrid retrieval (BM25 + semantic) with RRF — relevant results every query.
  • • 200+ reusable protocols for debugging, shipping, ops — saves reinvention.
  • • Write-back memory logs every decision for full audibility.

What frustrates them

  • • Very small community means scarce support and few third-party examples.
  • • Documentation is thin on key protocols like Triple-Lock and Zero-Point Codex.
  • • Setup is not plug-and-play — requires comfort with Markdown and CLI.
  • • No native integrations with dev tools like Slack, Jira, or VS Code yet.
