OpenClaw agents should share approved operational knowledge through scoped workspace files or a maintained knowledge layer, while credentials, personal data, and raw customer records stay outside shared memory. Give each agent its own workspace and tool policy, expose only the minimum shared material, redact before promotion, and test retrieval with an agent that should be denied. Memory is context, not an access-control system.
Quick answer
Use a shared memory layer for reusable facts, decisions, procedures, and handoff notes. Keep secrets in a secret store, isolate agents with separate workspaces, restrict tools per role, and require approval for sensitive actions. OpenClaw documents memory as Markdown stored in an agent workspace and explicitly says memory can preserve approval context but cannot enforce policy. Hard controls belong in tool policy, sandboxing, and approvals. OpenClaw memory documentation
Choose a shared knowledge layer when several trusted agents need the same operating context. Choose separate gateways, credentials, OS users, or hosts when users or workloads do not share a trust boundary. OpenClaw security guidance
What counts as shared agent memory?
Shared agent memory is durable context that more than one agent can retrieve or read while doing work. It can include approved procedures, product facts, decisions, project status, and handoff notes. In OpenClaw, the built-in memory model uses Markdown files in each agent workspace, with curated long-term memory separated from dated working notes. OpenClaw memory documentation
That definition matters because a memory file is readable context. If a credential or private customer record lands there, every agent with access may be able to retrieve it later. A polite instruction inside the same file is not a security boundary.
Which controls should you evaluate first?
Judge a memory-sharing design against these seven criteria before choosing a setup.
| Criterion | Safe default | What to verify |
|---|---|---|
| Best fit | Share procedures, decisions, approved facts, and handoffs | Every shared item has an owner and a business reason |
| Setup burden | Start with separate agent workspaces and a small curated shared layer | New agents do not inherit unrelated files |
| Management | Assign review, expiry, correction, and deletion ownership | Stale or disputed facts can be removed |
| Privacy and security | Exclude credentials, authentication material, unnecessary personal data, and raw transcripts | Search cannot retrieve excluded material |
| Integrations | Give each role only the tools and destinations it needs | A research agent cannot reach payroll or production systems |
| Limitations | Treat memory as context, not enforcement | Tool policy, sandboxing, and approvals remain active |
| Verification | Test with both an allowed agent and a denied agent | The allowed query succeeds and the denied query fails |
The safest useful design is rarely one giant memory folder. It is a small shared layer surrounded by role-specific workspaces and hard execution controls.
How should the memory layers be separated?
Use three practical layers.
- Put company-approved, non-secret knowledge in a shared layer. Procedures, terminology, public product facts, escalation paths, and reviewed decisions belong here.
- Keep role-specific working notes in each agent's own workspace. Sales drafts do not need to enter the support agent's memory by default.
- Keep credentials and sensitive source records outside memory. OpenClaw's secrets tool can store a credential without placing its value in chat, transcripts, tool results, or model context. OpenClaw secrets documentation
OpenClaw warns against reusing the same agentDir across agents because each agent has its own authentication store. Its multi-agent documentation also supports separate workspaces, per-agent sandboxes, and per-agent tool allow and deny rules. OpenClaw multi-agent sandbox and tools
How do you implement safe sharing in OpenClaw?
1. Classify information before an agent writes it
Use a short classification policy that people can remember. Public and internal operational facts may be shareable after review. Restricted material stays in a role workspace. Secrets never enter memory. Personal or customer data should be minimized and retained only when the workflow genuinely needs it.
2. Give every agent a separate workspace
Do not point every role at the same writable folder. OpenClaw supports per-agent workspaces and warns that authentication directories must not be reused across agents. Separate workspaces reduce accidental retrieval and make deletion or investigation much cleaner. OpenClaw multi-agent sandbox and tools
3. Expose the shared layer read-only where possible
OpenClaw sandbox workspace access supports none, ro, and rw. The documented default is none, which keeps the main agent workspace out of the sandbox. Read-only access mounts the workspace without write, edit, or patch operations. OpenClaw workspace access
4. Restrict tools independently from memory
A support agent may need approved customer context but should not automatically gain shell execution, browser sessions, billing tools, or cross-channel messaging. OpenClaw applies tool profiles and global, provider, agent, and sandbox-specific allow and deny policies in a documented precedence order. OpenClaw multi-agent sandbox and tools
5. Put secrets in the secret store
OpenClaw's protected secret flow keeps credential values out of the model context and lets the operator constrain egress to approved hosts. The documentation warns that allowed hosts govern egress substitution, while configuration references follow their own rules. Do not paste a key into a memory note and call the folder private. OpenClaw secrets documentation
6. Add review and approval points
Require human approval before promoting sensitive notes into shared memory and before high-impact actions use retrieved context. OpenClaw states that memory may record approval context, but enforcement must come from approval settings and tool controls. OpenClaw memory documentation
7. Test the negative case
Run a harmless canary query from an agent that should not see the record. Then attempt the related tool action. A useful test proves both retrieval isolation and action denial. Run openclaw security audit after configuration changes to catch drift in the wider deployment. OpenClaw security guidance
What failure model should you plan for?
Assume four things can go wrong. An agent may save sensitive text into the wrong layer. Search may retrieve context for the wrong role. A tool may turn harmless context into an unauthorized action. Old information may remain searchable after the business believes it has changed.
The controls map cleanly to those failures. Classification and review reduce bad writes. Workspace scope reduces unintended reads. Tool policy, sandboxing, and approvals limit actions. Ownership, expiry, and deletion handle stale data. None of these controls is perfect alone. Together, they make the mistake smaller and easier to investigate.
OpenClaw says sandboxing reduces blast radius but is not a perfect security boundary. It also says tool policy applies before sandbox rules and that elevated execution is an explicit escape hatch. OpenClaw sandboxing documentation
When is ClawBud a sensible choice?
ClawBud fits teams that want a fully managed Agentic OS for an AI agent army, including managed OpenClaw on a private cloud computer, without owning the routine setup and operating work. For this query, the relevant product facts are the private customer environment, managed support, and per-agent firewall boundaries. Those controls help with infrastructure isolation, but they do not replace information classification or careful tool permissions.
ClawBud is not the right fit when company policy requires every memory store, key, gateway, host, and operating procedure to remain inside infrastructure run solely by an internal security team. Self-managed OpenClaw is the cleaner choice in that case.
What should the final verification checklist include?
- Every agent has a named role, separate workspace, and documented trust boundary.
- Shared memory contains approved operating context, not credentials or raw sensitive records.
- Secret values use a secret store or supported secret reference.
- Shared files are read-only unless an agent has a documented reason to write.
- Tool access matches the role and is tested with denied actions.
- Sensitive promotion and high-impact execution require approval.
- Retention, correction, deletion, and incident ownership are assigned.
- An allowed retrieval test and a denied retrieval test both pass.
- `openclaw security audit` is run after material configuration changes.
Quotable facts
OpenClaw memory is stored context. It is not an access-control system.
A shared memory layer should contain the facts every approved agent needs, not every fact the company owns.
The security test is incomplete until an agent that should be denied actually fails to retrieve or act on the data.
Frequently asked questions
Can multiple OpenClaw agents use the same memory?
They can use shared files or a shared knowledge layer, but broad writable access is a poor default. Keep each agent's working memory separate and expose reviewed common knowledge deliberately. OpenClaw supports per-agent workspaces and policies, which makes role separation practical without blocking useful handoffs. OpenClaw multi-agent sandbox and tools
Should API keys ever be stored in agent memory?
No. Store keys in a supported secret store or SecretRef flow. OpenClaw's secrets tool is designed so protected values do not appear in chat, transcripts, tool results, or model context. Restrict any permitted egress to the exact destination hosts that need the credential. OpenClaw secrets documentation
Is a private server enough to prevent memory leaks?
No. A private host reduces infrastructure sharing, but an over-permissioned agent can still read the wrong file or call the wrong tool inside that environment. Safe memory sharing also needs separate workspaces, data classification, role-specific tool policy, approval gates, and negative access tests.
Should shared memory be read-only?
Usually, yes. Read-only access is a strong default for approved company knowledge because agents can use the material without silently changing the source. Give write access only to a narrow publishing or curation role, then keep review history and a clear owner for corrections.
How often should shared agent memory be reviewed?
Review should follow risk and change rate, not a ceremonial calendar. High-impact procedures and customer-facing facts need review when their source changes. Lower-risk reference material can use an expiry date and periodic sweep. Any incident involving wrong retrieval should trigger immediate review of scope, source, and access logs.
Does sandboxing stop an agent from reading shared memory?
Only when its workspace and mount policy are configured to do so. OpenClaw supports no access, read-only access, and read-write access for sandbox workspaces. Sandboxing limits execution scope, while tool policy and workspace configuration decide what remains available. It is a control layer, not a magic privacy switch. OpenClaw workspace access
When should teams use separate gateways or hosts?
Use separate gateways, credentials, and preferably separate OS users or hosts when the participants or workloads do not share trust. OpenClaw's security guidance defines one trust boundary per gateway and recommends splitting mixed-trust or adversarial deployments. That is stronger than trying to solve hostile tenancy with memory instructions. OpenClaw security guidance
