title: "Session management"
---
OpenClaw routes every inbound message to a **session** based on where it came
from: DMs, group chats, cron jobs, etc. All session state is owned by the
**gateway**; UI clients query the gateway for session data.
To continue the same Gateway-owned session in the Control UI, terminal, or a
coding harness, see [Session synchronization and attachment](/concepts/session-attachment).
For the personal-agent default — one rolling conversation shared by all your
DM channels, with group activity and background work flowing into it — see
[The main session](/concepts/main-session).
## How messages are routed
| Source | Behavior |
| --------------- | ----------------------------- |
| Direct messages | Shared session by default |
| Group chats | Isolated per group by default |
| Rooms/channels | Isolated per room by default |
| Cron jobs | Fresh session per run |
| Webhooks | Isolated per hook |
Native catalog source IDs, Matrix room and thread IDs, and Signal group IDs are
case-sensitive: IDs that differ only by case identify different conversations.
With `session.scope: "global"`, the selected agent still owns its session.
The shared key `global` does not merge different agents' conversations:
commands, skills, replies, and background task notifications retain the
agent selected by the route or explicit request.
Session lists, model filters, previews, and sharing controls also retain the
stored conversation's agent, rather than the aggregate view's default agent.
Stopping with `/stop`, deleting, resetting, or archiving a session cancels only that agent's work for
the selected conversation. Another agent's active turn and queued messages are
preserved even when the agents use the same session key.
## DM isolation
By default, all DMs share one session for continuity, which is fine for
single-user setups.
<Warning>
If multiple people can message your agent, enable DM isolation. Without it, all
users share the same conversation context, so Alice's private messages would be
visible to Bob.
</Warning>
```json5
{
session: {
dmScope: "per-channel-peer", // isolate by channel + sender
},
}
```
`session.dmScope` options:
| Value | Behavior |
| -------------------------- | -------------------------------------------------------- |
| `main` (default) | All DMs share the [main session](/concepts/main-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 |
Slack Agent View and Assistant View DMs are the exception: each visible root gets
its own `:thread:<rootTs>` session on top of the base that `dmScope` selects, so
those conversations stay isolated even under `main`. See
[Agent View DMs](/channels/slack/threads-and-sessions#agent-view-dms).
<Tip>
If the same person contacts you from multiple channels, use
`session.identityLinks` to map their identities to one canonical peer id so
they share a session.
</Tip>
Verify your setup with `openclaw security audit`.
## Retired channel docking
Channel docking and manual cross-channel reply focus have been removed. The
`/dock-*` commands no longer move a session's reply destination to another
channel.
Use `session.identityLinks` to associate a person's identities for DM session
routing, or [thread-bound sessions](/tools/subagents#thread-bound-sessions) to
keep a supported conversation attached to a subagent. These are separate
features; neither restores manual cross-channel docking.
## Group and room routing
`session.groupScope` controls where non-direct peers store conversation
context:
| Value | Behavior |
| --------------------- | ----------------------------------------------------------------------------------------- |
| `per-group` (default) | Keep each group, room, or channel in its existing channel-scoped session |
| `main` | Route groups, rooms, and channels into the agent's [main session](/concepts/main-session) |
A route binding can override the global value. This is useful when only a
named team room should join the main conversation:
```json5
{
bindings: [
{
agentId: "main",
match: {
channel: "slack",
peer: { kind: "channel", id: "C0123TEAM" },
},
session: { groupScope: "main" },
},
],
}
```
Use `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 expires 24 hours after creation or when the Gateway restarts, whichever comes first. Activity does not extend its lifetime. Expiry stops active work and deletes the session and transcript without an archive. Incognito 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.
Delegated work uses its native execution and completion owners. Live subagent activity and completion delivery remain available.
The `incognito-` 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. Incognito content is excluded from ordinary Gateway output, delivery and response diagnostics, WebSocket event previews, raw-stream, cache-trace, and Anthropic payload logs. Live replies remain available, and OpenClaw still records operational diagnostics and 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](/concepts/active-memory#remember-across-conversations) 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 same
`sessionId`; 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`, default `4`, 0-23) on the gateway host. Daily
freshness is based on when the current `sessionId` started, not on later
metadata writes.
- **Idle reset** (`mode: "idle"`) - opt into a new session after `session.reset.idleMinutes`
of 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 `/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 follow the same no-automatic-reset
default. Use `/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:
```json5
{
session: {
reset: { mode: "daily", atHour: 4 },
resetByType: {
group: { mode: "idle", idleMinutes: 120 },
thread: { mode: "daily", atHour: 6 },
},
resetByChannel: {
discord: { mode: "idle", idleMinutes: 10080 },
},
},
}
```
`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.
## Gateway restart recovery
When a Gateway restart interrupts an active turn, OpenClaw tries to continue
the existing session automatically. Three attempts that fail to start a backend
turn exhaust the recovery budget. Once a real backend turn starts,
the budget refreshes, so a later Gateway restart does not consume the old allowance.
Accepting, queueing, or preparing a resume request alone does not refresh it.
CLI backends that do not report turn acceptance refresh the budget only after
observed assistant output or tool activity; silent startup does not refresh it.
When replaying an interrupted turn, recovery preserves its recorded tool calls
and results, including nested tool activity, and reuses the original user message.
A completed reply or a later user message closes that turn to replay.
Messages sent while restart recovery is waiting to start stay pending. Once
recovery starts, they follow the session's normal message queue policy. You do
not need to resend a message just because recovery is waiting for capacity.
Stopping or replacing the session still cancels pending work.
If automatic recovery is exhausted, the transcript remains available. Use
**Resume in new session** in WebChat, or `/new` or `/reset` in other channels,
to start a replacement session.
## Where state lives
- **Runtime session rows and transcripts:** `~/.openclaw/agents/<agentId>/agent/openclaw-agent.sqlite` by default
- **Archived transcript files:** `~/.openclaw/agents/<agentId>/sessions/`
- **Legacy row migration source:** `~/.openclaw/agents/<agentId>/sessions/sessions.json`
Archive discovery uses the selected store, recorded transcript paths, and agent
directories. The pre-agent `~/.openclaw/sessions/` directory is no longer an
implicit fallback; explicitly configured paths still work.
The session rows in the per-agent SQLite database keep 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.
To import legacy `sessions.json` rows and hot transcript JSONL history from an
older installation, stop the Gateway, back up its state, and run
`openclaw doctor --fix` before restarting it. Gateway and local CLI startup use
SQLite without importing, restoring, or rewriting legacy session files.
If startup finds a legacy store, it refuses readiness and prints the Doctor
command for the active profile instead of silently starting with empty history.
During Doctor import, 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](/cli/doctor#session-sqlite-migration) for inspection and validation.
## Session maintenance
OpenClaw bounds session storage over time via `session.maintenance`, defaults
shown:
```json5
{
session: {
maintenance: {
mode: "enforce", // "enforce" applies cleanup; "warn" only reports
pruneAfter: "30d",
archiveDashboardAfter: "7d", // false or 0 disables this dashboard trigger
maxEntries: 5000,
preserveRecent: false, // opt in with a duration such as "7d"
},
},
}
```
For production-sized `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.
Ordinary entry writes also arm background maintenance at the next age boundary,
with a periodic recheck every 30 minutes while the store remains open. This lets
eligible sessions age out without further traffic. Writes that cannot change
age or count maintenance outcomes skip candidate scans. Automatic planning reads
only retention and protection metadata before entering the foreground write queue;
cap selection retains only the required oldest eligible entries. The writer checks
the prepared store revision before applying changes, so concurrent updates are
reconsidered instead of overwritten.
If writes invalidate an automatic maintenance plan, its replacement waits for
a quiet window after the last write (one second, then two seconds). Three
consecutive invalidations pause automatic retries and log the cause; a new
entry write can schedule another attempt. `warn` mode captures the maintenance
age fact without constructing or dispatching automatic reclamation.
`maxEntries` defaults to 5000 unarchived session rows. Archived rows do not consume
the cap. Existing explicit limits remain unchanged.
When pressure exceeds the cap, cleanup archives the oldest eligible ordinary
sessions instead of deleting their transcripts. Synthetic runtime sessions such
as cron, hooks, heartbeat, ACP, and sub-agents remain disposable and may be
removed. Pinned root sessions, active or admitted work, model-locked sessions, and
durable external conversation pointers are protected; the unarchived total can
therefore remain above the cap when protected rows alone exceed it.
Root sessions and sessions auto-parented to the agent's Home root can be pinned;
genuine child sessions and subagent runs reject pin requests. Persistent child
sessions retain their sidebar nesting; subagent runs appear in transcript activity
and session transcripts. Existing child pins disappear and no longer protect the session
from maintenance.
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 direct,
group, 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,
and `pruneAfter` archives other eligible durable sessions in place after 30 days
by default, preserving their session ids and transcript generations. Disposable
automation rows still delete at their age cutoff.
Pinned sessions and manual, legacy, age-retention, stale-dashboard, or recovery
archives are user-protected and exempt from automatic maintenance. Sessions archived because
`maxEntries` was reached record that reason and remain searchable/restorable
until physical usage exceeds `maxDiskBytes`; disk-budget cleanup may then delete
the oldest cap archives after cheaper artifacts and unreferenced history are
exhausted. Sessions without a recorded archive reason remain protected.
After skipping a history generation or archived session, disk-budget cleanup
rechecks physical usage before considering another deletion. A measurement
failure stops the sweep.
Background disk-budget checks run at most every 30 minutes on entry writes.
Delete and reset operations can request a check sooner, but repeated requests
coalesce to at most one forced check per minute per store. If cleanup exhausts
eligible history and the store remains over budget, automatic checks back off
for 30 minutes and log one warning until the pressure clears or the budget changes.
The warning recommends raising `session.maintenance.maxDiskBytes` or exporting
and deleting unneeded sessions. Checks resume on subsequent activity;
`openclaw sessions cleanup --enforce` remains available immediately.
Cleanup first tries to truncate the WAL without waiting for readers. If readers
prevent truncation, a complete PASSIVE checkpoint is sufficient: frames relevant
to cleanup must have reached the main database, even if the WAL file remains allocated.
Retained WAL bytes still count toward the physical budget. Successful cleanup
logs one outcome with the before/after bytes and removal counts.
An incomplete SQLite WAL checkpoint is a separate deferral. Cleanup preserves
archives and history instead of deleting more data behind the blocked checkpoint.
The result records `deferredReason: "checkpoint-incomplete"`, WAL bytes before and
after, and the checkpoint outcome. Automatic and manual budget passes remain
deferred until the checkpoint owner records completion after the pending cleanup
work. Newer frames from concurrent writes do not erase that completion. Each SQLite cleanup
deletion or vacuum commit requires a new completion before further pruning, so a
reader pinning those changes still defers cleanup. Ordering uses monotonic time;
elapsed time, a budget change, or a system clock correction cannot release the gate.
Normal periodic checkpointing continues, and subsequent activity can resume cleanup
after recovery.
Look for `session history disk budget deferred until a completed WAL checkpoint is observed`
in the Gateway log. Its checkpoint fields include bounded operation names for
explicitly tracked readers, connection and thread IDs, and open-transaction flags.
Collecting these facts does not keep connections open or change worker retirement.
They do not prove which connection holds the blocking SQLite read mark. Raw native
statements outside explicit reader tracking, other workers, and other processes
can remain unidentified. No transcript contents, SQL text, or bound values are included.
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`.
