Mimir Claw 🧠

Persistent memory sweeper for OpenClaw.

If your agent keeps forgetting what you talked about yesterday — this fixes that.

Mimir Claw reads your OpenClaw session transcripts and appends clean, daily Markdown logs to your workspace's memory/ directory. Your agent can then read those files on startup and actually remember prior conversations.

Named for Mímir — the Norse god renowned for his knowledge and wisdom.

The problem

OpenClaw agents wake up fresh each session. Unless you write things down, they forget. Built-in MEMORY.md curation is great for long-term wisdom, but there's no raw, searchable record of what was actually said across sessions and channels.

The fix

A ~250-line Python script + a launchd/cron job that, every 15 minutes:

1. Scans ~/.openclaw/agents/<agent>/sessions/*.jsonl
2. Extracts new user + assistant messages since last run (cursor-based, incremental)
3. Strips OpenClaw's injected metadata blocks and heartbeat noise
4. Appends clean Markdown blocks to <workspace>/memory/YYYY-MM-DD-chats.md

Your agent can then read today + yesterday's *-chats.md on session start and have continuous context.
