Active Memory
Active memory is an optional plugin-owned blocking memory sub-agent that runs before the main reply for eligible conversational sessions. It exists because most memory systems are capable but reactive. They rely on the main agent to decide when to search memory, or on the user to say things like “remember this” or “search memory.” By then, the moment where memory would have made the reply feel natural has already passed. Active memory gives the system one bounded chance to surface relevant memory before the main reply is generated.Paste This Into Your Agent
Paste this into your agent if you want it to enable Active Memory with a self-contained, safe-default setup:main agent, keeps it limited to direct-message
style sessions by default, lets it inherit the current session model first, and
uses the configured fallback model only if no explicit or inherited model is
available.
After that, restart the gateway:
Turn active memory on
The safest setup is:- enable the plugin
- target one conversational agent
- keep logging on only while tuning
openclaw.json:
plugins.entries.active-memory.enabled: trueturns the plugin onconfig.agents: ["main"]opts only themainagent into active memoryconfig.allowedChatTypes: ["direct"]keeps active memory on for direct-message style sessions only by default- if
config.modelis unset, active memory inherits the current session model first config.modelFallbackoptionally provides your own fallback provider/model for recallconfig.promptStyle: "balanced"uses the default general-purpose prompt style forrecentmode- active memory still runs only on eligible interactive persistent chat sessions
How to see it
Active memory injects hidden system context for the model. It does not expose raw<active_memory_plugin>...</active_memory_plugin> tags to the client.
Session toggle
Use the plugin command when you want to pause or resume active memory for the current chat session without editing config:plugins.entries.active-memory.enabled, agent targeting, or other global
configuration.
If you want the command to write config and pause or resume active memory for
all sessions, use the explicit global form:
plugins.entries.active-memory.config.enabled. It leaves
plugins.entries.active-memory.enabled on so the command remains available to
turn active memory back on later.
If you want to see what active memory is doing in a live session, turn on the
session toggles that match the output you want:
- an active memory status line such as
Active Memory: ok 842ms recent 34 charswhen/verbose on - a readable debug summary such as
Active Memory Debug: Lemon pepper wings with blue cheese.when/trace on
When it runs
Active memory uses two gates:- Config opt-in
The plugin must be enabled, and the current agent id must appear in
plugins.entries.active-memory.config.agents. - Strict runtime eligibility Even when enabled and targeted, active memory only runs for eligible interactive persistent chat sessions.
Session types
config.allowedChatTypes controls which kinds of conversations may run Active
Memory at all.
The default is:
Where it runs
Active memory is a conversational enrichment feature, not a platform-wide inference feature.| Surface | Runs active memory? |
|---|---|
| Control UI / web chat persistent sessions | Yes, if the plugin is enabled and the agent is targeted |
| Other interactive channel sessions on the same persistent chat path | Yes, if the plugin is enabled and the agent is targeted |
| Headless one-shot runs | No |
| Heartbeat/background runs | No |
Generic internal agent-command paths | No |
| Sub-agent/internal helper execution | No |
Why use it
Use active memory when:- the session is persistent and user-facing
- the agent has meaningful long-term memory to search
- continuity and personalization matter more than raw prompt determinism
- stable preferences
- recurring habits
- long-term user context that should surface naturally
- automation
- internal workers
- one-shot API tasks
- places where hidden personalization would be surprising
How it works
The runtime shape is: The blocking memory sub-agent can use only:memory_searchmemory_get
NONE.
Query modes
config.queryMode controls how much conversation the blocking memory sub-agent sees.
Prompt styles
config.promptStyle controls how eager or strict the blocking memory sub-agent is
when deciding whether to return memory.
Available styles:
balanced: general-purpose default forrecentmodestrict: least eager; best when you want very little bleed from nearby contextcontextual: most continuity-friendly; best when conversation history should matter morerecall-heavy: more willing to surface memory on softer but still plausible matchesprecision-heavy: aggressively prefersNONEunless the match is obviouspreference-only: optimized for favorites, habits, routines, taste, and recurring personal facts
config.promptStyle is unset:
config.promptStyle explicitly, that override wins.
Example:
Model fallback policy
Ifconfig.model is unset, Active Memory tries to resolve a model in this order:
config.modelFallback controls the configured fallback step.
Optional custom fallback:
config.modelFallbackPolicy is retained only as a deprecated compatibility
field for older configs. It no longer changes runtime behavior.
Advanced escape hatches
These options are intentionally not part of the recommended setup.config.thinking can override the blocking memory sub-agent thinking level:
config.promptAppend adds extra operator instructions after the default Active
Memory prompt and before the conversation context:
config.promptOverride replaces the default Active Memory prompt. OpenClaw
still appends the conversation context afterward:
NONE
or compact user-fact context for the main model.
message
Only the latest user message is sent.
- you want the fastest behavior
- you want the strongest bias toward stable preference recall
- follow-up turns do not need conversational context
- start around
3000to5000ms
recent
The latest user message plus a small recent conversational tail is sent.
- you want a better balance of speed and conversational grounding
- follow-up questions often depend on the last few turns
- start around
15000ms
full
The full conversation is sent to the blocking memory sub-agent.
- the strongest recall quality matters more than latency
- the conversation contains important setup far back in the thread
- increase it substantially compared with
messageorrecent - start around
15000ms or higher depending on thread size
Transcript persistence
Active memory blocking memory sub-agent runs create a realsession.jsonl
transcript during the blocking memory sub-agent call.
By default, that transcript is temporary:
- it is written to a temp directory
- it is used only for the blocking memory sub-agent run
- it is deleted immediately after the run finishes
config.transcriptDir.
Use this carefully:
- blocking memory sub-agent transcripts can accumulate quickly on busy sessions
fullquery mode can duplicate a lot of conversation context- these transcripts contain hidden prompt context and recalled memories

Recommended setup
Start withrecent.
/verbose on for the
normal status line and /trace on for the active-memory debug summary instead
of looking for a separate active-memory debug command. In chat channels, those
diagnostic lines are sent after the main assistant reply rather than before it.
Then move to:
messageif you want lower latencyfullif you decide extra context is worth the slower blocking memory sub-agent
Debugging
If active memory is not showing up where you expect:- Confirm the plugin is enabled under
plugins.entries.active-memory.enabled. - Confirm the current agent id is listed in
config.agents. - Confirm you are testing through an interactive persistent chat session.
- Turn on
config.logging: trueand watch the gateway logs. - Verify memory search itself works with
openclaw memory status --deep.
maxSummaryChars
- lower
queryMode - lower
timeoutMs - reduce recent turn counts
- reduce per-turn char caps
Common issues
Embedding provider changed unexpectedly
Active Memory uses the normalmemory_search pipeline under
agents.defaults.memorySearch. That means embedding-provider setup is only a
requirement when your memorySearch setup requires embeddings for the behavior
you want.
In practice:
- explicit provider setup is required if you want a provider that is not
auto-detected, such as
ollama - explicit provider setup is required if auto-detection does not resolve any usable embedding provider for your environment
- explicit provider setup is highly recommended if you want deterministic provider selection instead of “first available wins”
- explicit provider setup is usually not required if auto-detection already resolves the provider you want and that provider is stable in your deployment
memorySearch.provider is unset, OpenClaw auto-detects the first available
embedding provider.
That can be confusing in real deployments:
- a newly available API key can change which provider memory search uses
- one command or diagnostics surface may make the selected provider look different from the path you are actually hitting during live memory sync or search bootstrap
- hosted providers can fail with quota or rate-limit errors that only show up once Active Memory starts issuing recall searches before each reply
memory_search can operate
in degraded lexical-only mode, which typically happens when no embedding
provider can be resolved.
Do not assume the same fallback on provider runtime failures such as quota
exhaustion, rate limits, network/provider errors, or missing local/remote
models after a provider has already been selected.
In practice:
- if no embedding provider can be resolved,
memory_searchmay degrade to lexical-only retrieval - if an embedding provider is resolved and then fails at runtime, OpenClaw does not currently guarantee a lexical fallback for that request
- if you need deterministic provider selection, pin
agents.defaults.memorySearch.provider - if you need provider failover on runtime errors, configure
agents.defaults.memorySearch.fallbackexplicitly
Debugging provider issues
If Active Memory is slow, empty, or appears to switch providers unexpectedly:- watch the gateway logs while reproducing the problem; look for lines such as
active-memory: ... start|done,memory sync failed (search-bootstrap), or provider-specific embedding errors - turn on
/trace onto surface the plugin-owned Active Memory debug summary in the session - turn on
/verbose onif you also want the normal🧩 Active Memory: ...status line after each reply - run
openclaw memory status --deepto inspect the current memory-search backend and index health - check
agents.defaults.memorySearch.providerand related auth/config to make sure the provider you expect is actually the one that can resolve at runtime - if you use
ollama, verify the configured embedding model is installed, for exampleollama list
/trace on so the Active Memory debug line reflects the new embedding path.
