Summary

The /compact command fails for non-default agents because handleCompactCommand does not forward agentDir to compactEmbeddedPiSession. This causes the compaction to always look for auth credentials in ~/.openclaw/agents/main/agent/auth-profiles.json (the hardcoded DEFAULT_AGENT_ID) instead of the correct agent directory.

Error:

⚙️ Compaction failed: No API key found for provider "anthropic".
Auth store: ~/.openclaw/agents/main/agent/auth-profiles.json
(agentDir: ~/.openclaw/agents/main/agent)

Root Cause

In handleCompactCommand, the call to compactEmbeddedPiSession omits agentDir:

// handleCompactCommand
const result = await compactEmbeddedPiSession({
    sessionId,
    sessionKey: params.sessionKey,
    workspaceDir: params.workspaceDir,
    // ❌ agentDir not passed — falls back to DEFAULT_AGENT_ID ("main")
    config: params.cfg,
    ...
});

The fallback in compactEmbeddedPiSessionDirect:

const agentDir = params.agentDir ?? resolveOpenClawAgentDir();
// resolveOpenClawAgentDir() hardcodes DEFAULT_AGENT_ID = "main"

Note: The auto-compaction path (context overflow in runEmbeddedAttempt) correctly passes agentDir. Only the manual /compact command is affected.

Fix

One-liner — params.agentDir is already available in the handler scope, it just needs to be forwarded:

 const result = await compactEmbeddedPiSession({
     sessionId,
     sessionKey: params.sessionKey,
     workspaceDir: params.workspaceDir,
+    agentDir: params.agentDir,
     config: params.cfg,

Reproduction

1. Configure multiple agents (e.g. work + personal) with per-agent auth-profiles.json
2. Do NOT have a main agent directory (or have it without auth)
3. Send /compact to a non-default agent via Telegram
4. Compaction fails looking for auth in ~/.openclaw/agents/main/agent/

Environment

• OpenClaw 2026.2.17
• macOS arm64
• Two agents: work and personal (no main agent)
• Patched locally in dist; will revert on update
