Mine all historical Claude Code sessions for knowledge. By default the Stop hook only handles new sessions; this command backfills existing JSONL transcripts. It also opts you in to event-triggered mining for future sessions.
- Show how many sessions exist:
find ~/.claude/projects/ -name "*.jsonl" ! -path "*/subagents/*" -size +5k | wc -l- Tell the user approximately how long it will take (~3-5 seconds per session, plus Haiku API costs).
- Confirm with the user before starting — this can take hours for large histories and makes many Haiku API calls.
- Record the opt-in and start history backfill in the background:
mkdir -p ~/.memem && touch ~/.memem/.miner-opted-in
nohup PYTHONPATH="${CLAUDE_PLUGIN_ROOT}" python3 -m memem.server --mine-all > ~/.memem/mine-all.log 2>&1 &
echo "History mining started in background (PID $!)"- Tell the user:
- History mining is running in the background (log at
~/.memem/mine-all.log) - Future sessions will also be mined automatically — every Claude Code Stop event spawns
mine_deltato extract new turns - They can continue working normally
- New memories appear as they're extracted (Haiku-extracted, written to
~/obsidian-brain/memem/memories/) - Run
/memem-statusto check progress and Stop-hook registration - To opt out:
rm ~/.memem/.miner-opted-in(no daemon to stop)
