Sessions and memory

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.

Session lists reconcile invalidated metadata before returning rows. If a native session changes ownership during a list read, that row uses the configured model metadata while other sessions remain available. Native metadata is refreshed when that row is next invalidated; an unchanged list read does not retry it.

Conversation branch listing (sessions.branches.list) has a ten-second request deadline, including access checks and cold-transcript restoration. If it expires, the Gateway returns a retryable UNAVAILABLE error instead of an empty branch list. Retry after database preparation finishes. Required integrity checks and already-admitted storage cleanup keep their own lifetimes.

Compressed transcript archives are decoded directly from their source files; history, discovery, usage, and memory indexing do not create plaintext copies in the temporary directory. History retains navigation metadata and reads selected byte ranges through a bounded-memory stream. An archive that would expand past 4 GiB fails with a visible error and remains unchanged. Archive publication verifies compressed output against the original plaintext byte count, preserving compression and disk-budget retention. Doctor reports the size of read-cache directories left by older versions. openclaw doctor --fix (also run during updates) removes recognized cache files and the directory if empty, preserving unrelated entries. Cleanup is best effort: files still open on Windows may remain until a later run; current readers do not use them.

To continue the same Gateway-owned session in the Control UI, terminal, or a coding harness, see Session synchronization and attachment.

For turn ownership, queueing, stopping, and lifecycle mutation rules, see Session controller.

Retries with the same input key acknowledge an already committed input even after another turn has started. They do not append another user message or generate a second reply. Interrupted current turns can still resume; reusing a key for conflicting content or sender identity is refused.

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.

Delivered command exchanges from the shared dispatcher are conversation history too. OpenClaw appends the user's command and delivered reply as ordinary user/assistant messages. Native menus and command acknowledgements on Discord and Telegram, Slack argument menus, and Mattermost model pickers are also retained after delivery. Later turns and chat history can read these exchanges. Login, pairing, and sensitive /config set or /debug set values are redacted before storage. /new and /reset put their confirmation exchange in the new session; they do not rewrite the old session. /btw and /side stay ephemeral, and message edits or deletions do not rewrite earlier transcript rows.

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. In the Sessions page, enabling Unknown includes authorized unknown sessions owned by the selected agent. An agent-qualified key such as agent:ops:unknown is an ordinary session and remains visible when Unknown is off. Renaming, pinning, or editing session metadata retains the existing message preview without rereading the transcript. New messages, transcript replacements, completed transcript repairs, and cold-storage restoration refresh previews; changes to model selection or fallback state refresh the relevant model facts. When sessions.list requests includeLastMessage, rows can also include lastAssistantMessage with the latest visible assistant text and its timestamp. This field uses the same bounded recent transcript window as other previews; it is absent when no timestamped assistant text is available in that window. The general lastMessagePreview can still contain a user message. 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.

Creators and assigned owners

New delegated sessions and automations retain the verified human who initiated the work as their creator. This is normal behavior; no Labs switch is required. The assigned owner remains separate: reassignment alone does not transfer creator rights for sharing, public-link management, archive, or restore. Existing creator/admin authorization rules still apply. Existing records are not retroactively reassigned.

A selected tool user supplies execution authority, not evidence that they initiated the task. Autonomous work without a retained human stays agent/system-created. Creator attribution affects discovery, creator controls, and the personal-profile fallback when no human owner is assigned; it does not change the executing agent, model/tool permissions, or required sandbox identity.

Public links still require explicit publication. Attribution does not publish sessions automatically, change their anonymous read-only view, or expose private isolation metadata. Content exclusions, revocation, and future-message behavior are unchanged.

Attribution is stored alongside the original actor inside the existing creation record. Original actor fields and database schema versions are unchanged. A compatible older runtime ignores the additional attribution and uses its original creator rules; it retains the record when writing sessions, so returning to this runtime restores the attributed creator without changing sandbox identity. Retain the ordinary rollback safeguards: this feature does not make unrelated database-format changes readable by older binaries. An incompatible binary remains blocked rather than silently restoring an old backup and losing later writes.

Automatic session names

Interactive chat sessions without an explicit name generate a topic title in the background when the Gateway dispatches their message. Naming starts alongside worktree and reply preparation; it does not wait for the agent’s first progress event and does not block the turn. The name appears when the title model finishes. If the title request fails while overlapping a turn, it retries once after that turn settles. Explicit names and manual renames are preserved.

DM isolation

By default, all DMs share one session for continuity, which is fine for single-user setups.

json5
{  session: {    dmScope: "per-channel-peer", // isolate by channel + sender  },}

session.dmScope options:

Value Behavior
main (default) All DMs share the 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.

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 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

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. Finishing a turn does not close the thread, and 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.

Incognito agent turns use the same in-memory session owner from command preparation through execution, so the first turn can produce a reply without switching to the durable session store.

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 limits persisted session history and access through other gateway-mediated sessions; it does not make all tool, upload, approval, or configured diagnostic data ephemeral. The gateway owner or process operator can still 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

Independent sessions can initialize their first turns concurrently. Requests for the same session remain ordered; parent forks and resets retain their shared-state coordination.

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, including browser Talk consults. 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. The message that triggers an automatic reset continues in the new conversation. 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

A graceful Gateway stop or restart writes one small marker for each running root session, then aborts work promptly. A root is running when its agent loop, one of its descendant sub-agents, or one of its background processes is active. At startup, the Gateway clears the marker and sends one ordinary system input asking the agent to check current files, processes, sub-agents, and external actions before continuing. This includes channel threads and non-default agents; replies retain the session's recorded channel and thread. Marker persistence uses the process shutdown deadline. Shutdown and startup log per-agent marked/resumed counts and skip reasons.

Running children stop quietly and do not resume independently. Their root requester receives the single resume input and can inspect results, send new instructions, or spawn replacements. Cron occurrence sessions and ACP/external-harness sessions keep their own lifecycle owners.

The input uses the recorded human owner's current authority, or the human creator when no owner is set, narrowed by the session's current permission mode and tool policy. A deleted or archived session, removed principal, or lost access is skipped. A session without a human principal uses ordinary system-event authority. Saved operator or requester snapshots do not grant permissions.

The marker records the IDs of accepted user messages still queued at shutdown. Only those messages follow the resume input in FIFO order. Each retains its original app grant, ID membership, and scope and model limits, revalidated against current authority before replay and tool effects. Another sign-in by the same person cannot replace that source. Older crash-left queued rows remain inert. Missing or revoked sources produce an ordinary failed send that the sender can resend. New messages during the resumed run use normal steering and queue rules; they do not wait behind a special recovery predecessor.

A crash or SIGKILL writes no shutdown markers. Startup uses the existing persisted nonterminal run identity to resume an eligible root whose execution owner is gone. Successful chat commands do not create a running marker or trigger a recovery turn. Queued turns publish their running marker when execution starts, so a crash during their execution resumes that work once. Both sources produce one resume input per session. The agent must inspect uncertain effects before repeating them. The Control UI shows the ordinary conversation and resume turn without restart banners or interrupted-input notices. There is no manual sessions.recover method.

Already-produced outbound messages and media keep their existing delivery queue. An unknown delivery outcome can still require inspection; restarting does not prove that an external action or reply happened exactly once. See Restart recovery for shutdown, compatibility, and post-update checks.

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.

State directories reached through symlinks are supported on SQLite and PostgreSQL, including session deletion, transcript archiving, and retained cron history reads.

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. Finalized user voice transcripts update this only with a new committed entry; replayed, assistant-only, and rejected transcripts do not.
  • 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 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 and reply initialization 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. Reply preparation does not wait for unrelated retention cleanup. 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; age candidates must reach their enabled retention phase's cutoff, and maintenance looks up only active-session ancestry unless runtime identities need the full session-key inventory. Cap selection retains only the required oldest eligible entries. Automatic capacity cleanup yields the writer between batches of up to 64 entries; explicit cleanup remains exhaustive. The writer rechecks the selected rows and their protection before applying changes, so concurrent updates are reconsidered instead of overwritten. Activity on unrelated sessions and protection that has ended do not invalidate the plan. When an over-cap pass finds only durably protected entries, ordinary activity does not repeat that futile plan. New eligible entries, restored identities, lost entry protection, and changed policy reconsider it. Delivery cleanup resumes idle maintenance when it releases the session's remaining recovery protection. Temporary protection from active sessions, runtime providers, or recent activity does not suppress planning on ordinary writes; age deadlines and the periodic recheck still resume idle cleanup. While entry pressure still requires cleanup, capacity maintenance revisits entries once temporary write protection ends, without requiring another entry write. Releasing acquired session work also wakes idle capacity maintenance; overlapping work keeps the session protected until its final admission releases. If writes invalidate an automatic maintenance plan, its replacement waits for the scheduled retry delay (one second, then two seconds). Further writes coalesce into that retry without postponing it indefinitely. Three consecutive invalidations pause automatic retries and log the cause; a new entry write can schedule another attempt. warn mode skips automatic reclamation. Certified transcript backfill and usage-cache writes retain a protected-only no-op result while entry-change publications and scoped write receipts remain current. Unknown writes still invalidate that result and wait for the existing quiet window before replanning.

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 check 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 check 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. Unchanged entry patches do not schedule a check. 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. Per-agent legacy store locators and their canonical SQLite paths share this queue and backoff. Custom aggregate store locators retain their own maintenance scope. After a pass reclaims nothing, the next automatic check first inspects eligible data without reserving the foreground writer; protected-only pressure does not repeat archive pruning or checkpoints. Manual cleanup still runs immediately. 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. Archive pruning measures physical usage outside the foreground writer queue. Each deletion and page-reclamation unit retains its own admission, with a yield between reclamation units. Archive retention also selects candidates outside the writer queue, then rechecks and removes at most 16 rows per admission, yielding between batches while retaining the same 256-row selection limit per pass. Concurrent shrinkage can prune one additional oldest derived archive before the next measurement ends the sweep; canonical retention and deletion eligibility checks are unchanged.

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. Manual cleanup and subsequent throttled automatic checks retry the checkpoint: an earlier blocked observation cannot suspend cleanup indefinitely when another connection completes a checkpoint without publishing its result. Cleanup still requires the checkpoint owner to record 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. A published completion allows the next activity to retry immediately; otherwise the normal check interval applies.

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.
