openclaw - 💡(How to fix) Fix [BUG] read tool called without path - embedded agent warning

Bug Description

Embedded agent sessions emit a warning log:

[agent/embedded] read tool called without path: toolCallId=call_function_xxx argsType=object

Root Cause

The warning originates from auth-profiles-<hash>.js line ~164790, in the handleToolExecutionStart() function:

if (toolName === "read") {
    const record = args && typeof args === "object" ? args : {};
    const path = typeof record.path === "string" ? record.path : typeof record.file_path === "string" ? record.file_path : "";
    if (!path.trim()) {
        const argsPreview = typeof args === "string" ? args.slice(0, 200) : void 0;
        ctx.log.warn(`read tool called without path: toolCallId=${toolCallId} argsType=${typeof args}${argsPreview ? ` argsPreview=${argsPreview}` : ""}`);
    }
}

Problem

When an embedded agent (via session-fork or subagent) calls the read tool, the path parameter is not being passed through to the tool handler. The tool is being invoked with an empty args object or with missing path fields.

Impact

• Excessive warning logs flood the output on every embedded agent tool call
• Indicates a bug in how tool arguments are forwarded in session-fork/subagent contexts

Occurrence

Observed at:

• 08:00:28 +08:00 — embedded agent read tool call without path
• 08:00:39 +08:00 — repeated

Environment

• openclaw version: latest
• Platform: Windows_NT
• Node.js: v24.15.0
• Runtime: main session with embedded agent sessions

Expected Behavior

The read tool should always receive a valid path parameter when called. If the agent cannot determine the path, it should not call the tool at all rather than calling it with a missing path and emitting a warning.
