OpenClaw organizes conversations into sessions. Each message is routed to a
session based on where it came from — DMs, group chats, cron jobs, etc.
How messages are routed
| Source | Behavior |
|---|
| Direct messages | Shared session by default |
| Group chats | Isolated per group |
| Rooms/channels | Isolated per room |
| Cron jobs | Fresh session per run |
| Webhooks | Isolated per hook |
DM isolation
By default, all DMs share one session for continuity. This is fine for
single-user setups.
If multiple people can message your agent, enable DM isolation. Without it, all
users share the same conversation context — Alice’s private messages would be
visible to Bob.
The fix:
{
session: {
dmScope: "per-channel-peer", // isolate by channel + sender
},
}
Other options:
main (default) — all DMs share one session.
per-peer — isolate by sender (across channels).
per-channel-peer — isolate by channel + sender (recommended).
per-account-channel-peer — isolate by account + channel + sender.
If the same person contacts you from multiple channels, use
session.identityLinks to link their identities so they share one session.
Verify your setup with openclaw security audit.
Session lifecycle
Sessions are reused until they expire:
- Daily reset (default) — new session at 4:00 AM local time on the gateway
host. Daily freshness is based on when the current
sessionId started, not
on later metadata writes.
- Idle reset (optional) — new session after a period of inactivity. Set
session.reset.idleMinutes. Idle freshness is based on the last real
user/channel interaction, so heartbeat, cron, and exec system events do not
keep the session alive.
- Manual reset — type
/new or /reset in chat. /new <model> also
switches the model.
When both daily and idle resets are configured, whichever expires first wins.
Heartbeat, cron, exec, and other system-event turns may write session metadata,
but those writes do not extend daily or idle reset freshness. When a reset
rolls the session, queued system-event notices for the old session are
discarded so stale background updates are not prepended to the first prompt in
the new session.
Sessions with an active provider-owned CLI session are not cut by the implicit
daily default. Use /reset or configure session.reset explicitly when those
sessions should expire on a timer.
Where state lives
All session state is owned by the gateway. UI clients query the gateway for
session data.
- Store:
~/.openclaw/agents/<agentId>/sessions/sessions.json
- Transcripts:
~/.openclaw/agents/<agentId>/sessions/<sessionId>.jsonl
sessions.json keeps separate lifecycle timestamps:
sessionStartedAt: when the current sessionId began; daily reset uses this.
lastInteractionAt: last user/channel interaction that extends idle lifetime.
updatedAt: last store-row mutation; useful for listing and pruning, but not
authoritative for daily/idle reset freshness.
Older rows without sessionStartedAt are resolved from the transcript JSONL
session header when available. If an older row also lacks lastInteractionAt,
idle freshness falls back to that session start time, not to later bookkeeping
writes.
Session maintenance
OpenClaw automatically bounds session storage over time. By default, it runs
in warn mode (reports what would be cleaned). Set session.maintenance.mode
to "enforce" for automatic cleanup:
{
session: {
maintenance: {
mode: "enforce",
pruneAfter: "30d",
maxEntries: 500,
},
},
}
For production-sized maxEntries limits, Gateway runtime writes use a small high-water buffer and clean back down to the configured cap in batches. This avoids running full store cleanup on every isolated cron session. openclaw sessions cleanup --enforce applies the cap immediately.
Preview with openclaw sessions cleanup --dry-run.
Inspecting sessions
openclaw status — session store path and recent activity.
openclaw sessions --json — all sessions (filter with --active <minutes>).
/status in chat — context usage, model, and toggles.
/context list — what is in the system prompt.
