How messages are routed
DM isolation
By default, all DMs share one session for continuity, which is fine for single-user setups.session.dmScope options:
Dock linked channels
Dock commands move the current direct-chat session’s reply route to another linked channel without starting a new session. See Channel docking for examples, config, and troubleshooting. Verify your setup withopenclaw security audit.
Group and room routing
session.groupScope controls where non-direct peers store conversation
context:
A route binding can override the global value. This is useful when only a
named team room should join the main conversation:
peer.kind: "group" for providers that classify the room as a group.
The binding override wins over global session.groupScope. This setting
changes session-key selection only: DM routing, mention gating, delivery
context, and replies to the source room remain unchanged.
Incognito sessions
Incognito sessions are available only from the Control UI’s New thread screen. Turn on Incognito before starting the thread to keep its session entry, transcript, and compaction state in process memory instead of on disk. The thread disappears when the Gateway restarts, does not run OpenClaw’s automatic memory flush, and does not create a transcript archive when you reset or delete it. Codex-backed runs also start their harness thread in ephemeral mode, so Codex writes no rollout or local session-state files; other model providers use HTTP APIs and keep no local provider transcript in OpenClaw. Theincognito- segment is reserved for dashboard, subagent, and hidden internal session keys; openclaw doctor --fix renames any colliding legacy durable keys.
Incognito does not restrict the agent’s normal tools. An explicit request to save information, or any tool-driven file write, can still persist data outside the incognito session store. Your configured model provider still processes the messages you send, diagnostic logging remains unchanged, and OpenClaw still records content-free audit metadata such as HMAC references.
On multi-user gateways, incognito threads are visible only to admin-scope connections and never appear through another session’s agent session tools or transcript search. This protects them from storage and other gateway-mediated users, not from the gateway owner or process operator, who can always observe live sessions.
Remember across conversations
Separate transcripts control each conversation’s local history. For a personal or fully trusted agent,memory.search.rememberAcrossConversations: true
adds an optional retrieval step across that agent’s other private
conversations; it does not combine their transcripts.
Private direct and persistent explicit UI conversations can supply relevant
context to one another. Under default session.groupScope: "per-group", groups and channels stay separate in both directions:
their transcripts are not private recall sources, and replies in those
conversations do not receive private transcript context. The current
conversation is also excluded because its history is already loaded.
This setting does not change session keys, DM scope, routing, delivery, or
tools.sessions.visibility. Shared workspace memory in MEMORY.md and
memory/*.md also keeps its existing behavior. The current memory provider
must support protected private transcript recall; context engines such as
Lossless Claw remain independent and can run alongside it. See
Active Memory for setup
and runtime details.
Session lifecycle
Sessions are reused until you reset them manually or opt into an automatic reset policy:- No automatic reset (default
mode: "none") - sessions keep the samesessionId; compaction manages the active context as the conversation grows. - Daily reset (
mode: "daily") - opt into a new session at a configured local hour (session.reset.atHour, default4, 0-23) on the gateway host. Daily freshness is based on when the currentsessionIdstarted, not on later metadata writes. - Idle reset (
mode: "idle") - opt into a new session aftersession.reset.idleMinutesof inactivity. 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
/newor/resetin chat./new <model>also switches the model.
/reset or configure session.reset explicitly when those sessions
should expire on a timer.
Opt into automatic resets globally, then override them per chat type or channel:
resetByType supports direct, group, and thread. Doctor migrates legacy dm entries to direct and session.idleMinutes to session.reset.idleMinutes; the schema rejects both retired forms.
Where state lives
- Runtime session rows:
~/.openclaw/agents/<agentId>/agent/openclaw-agent.sqlite - Archived transcript files:
~/.openclaw/agents/<agentId>/sessions/ - Legacy row migration source:
~/.openclaw/agents/<agentId>/sessions/sessions.json
sessionStartedAt: when the currentsessionIdbegan; 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.
openclaw doctor --fix import legacy sessions.json rows and hot transcript JSONL history into
SQLite automatically. Rows without sessionStartedAt are resolved from the
legacy 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. Use openclaw doctor --session-sqlite inspect --session-sqlite-all-agents and the Doctor migration
sequence when you want explicit
inspection or validation evidence.
Session maintenance
OpenClaw bounds session storage over time viasession.maintenance, defaults
shown:
maxEntries limits, Gateway runtime writes use a small
high-water buffer and clean back down to the configured cap in batches.
Session store reads do not prune or cap entries during Gateway startup, so
startup and isolated cron sessions do not pay for a full store cleanup.
openclaw sessions cleanup --enforce applies the cap immediately.
maxEntries counts every live session row. Archived or pinned sessions, active
or admitted work, model-locked sessions, and durable external conversation
pointers are protected from automatic eviction, but still consume the cap.
Cleanup removes the oldest unprotected rows until it reaches maxEntries or
runs out of eligible victims. The total can therefore remain above the cap when
protected rows alone exceed it or active work temporarily blocks eviction.
Cleanup does not unprotect those rows; unarchive, unpin, wait for active work to
finish, or explicitly delete sessions you no longer want to retain.
Gateway model-run probe sessions are short-lived by default. Rows matching
agent:*:explicit:model-run-<uuid> use fixed 24h retention, but cleanup is
pressure-gated: it only removes stale probe rows when session-entry
maintenance/cap pressure is reached, and runs before the broader stale-entry
age cutoff and entry cap. Normal direct, group, thread, cron, hook, heartbeat,
ACP, and sub-agent sessions do not inherit this 24h retention.
Maintenance preserves durable external conversation pointers, including group
sessions and thread-scoped chat sessions, while still allowing synthetic cron,
hook, heartbeat, ACP, and sub-agent entries to age out.
Shared or high-volume installations can set preserveRecent to protect
recently active interactive sessions and every SQLite history generation owned
by those sessions. The option is disabled when omitted or set to false, so
personal installations keep the normal oldest-first policy. Synthetic
model-run, cron, hook, heartbeat, ACP, and sub-agent sessions remain eligible
for bounded cleanup. Protection can temporarily keep the store above its entry
or disk target; it expires after the configured inactivity window.
Recent-session protection does not change managed-worktree garbage collection;
durable dashboard sessions auto-archive after 7 days of inactivity by default,
while other session types still require an explicit archive action.
Archived and pinned sessions are user-protected and exempt from every automatic
maintenance path, including age pruning, entry caps, model-run cleanup, and
disk-budget eviction. They remain protected until you unarchive, unpin, or
explicitly delete them.
If you previously used DM isolation and later returned session.dmScope to
main, preview stale peer-keyed DM rows with
openclaw sessions cleanup --dry-run --fix-dm-scope. Applying the same flag
retires those old direct-DM rows and keeps their transcripts as deleted
archives.
Preview any maintenance run with openclaw sessions cleanup --dry-run.
