OpenClaw Session Keys and Routing Deep Dive

February 21, 20263 min readReviewed March 8, 2026

Session routing is the core of predictable OpenClaw behavior. Replies are not just tied to a model; they are tied to a session key strategy that decides how context is isolated across DMs, groups, channels, and accounts[1][2].

Default Session Model

OpenClaw treats one direct-chat session per agent as primary while group/channel traffic maps into non-main session keys. This prevents group memory from polluting personal DMs by default[1].

Common dmScope Choices

per-peer: one sender identity across channels.
per-channel-peer: channel + sender isolation (recommended default for mixed workspaces).
per-account-channel-peer: strongest separation for multi-account deployments[1].

Multi-Agent + Multi-Account Routing

In larger installs, each agent keeps isolated workspace/session state while channel account bindings decide which agent receives inbound traffic[2]. This avoids accidental cross-agent context bleed.

Configuration Example

{
  "session": {
    "dmScope": "per-channel-peer"
  },
  "agents": {
    "list": ["main", "ops", "sales"]
  }
}

Verification Commands

openclaw channels status --probe
openclaw channels capabilities
openclaw health
openclaw logs --follow

Design Recommendations

Use stricter dmScope as channel/account count grows.
Keep group channels non-main and mention-gated.
Document routing/binding decisions so operators can debug message paths quickly.

Why This Matters for Reliability

Most "wrong context" incidents are routing design issues, not model quality issues. Session-key discipline gives deterministic behavior under scale.
