Summary

Bug Description

When running openclaw sessions list with any argument (e.g., openclaw sessions list 2>&1), the CLI reports an error:

error: too many arguments for 'sessions'. Expected 0 arguments but got 1.

Steps to reproduce

However, the command exits with code 0 (success), making it impossible for scripts or monitoring tools to distinguish between a successful run and a failure.

Expected Behavior

• Command failure should return a non-zero exit code
• Exit code 0 should only be returned on success

Environment

• OpenClaw version: 2026.4.2 (commit d74a122)
• Node.js: v24.14.0
• Platform: Windows_NT 10.0.26200 (x64)
• Shell: PowerShell

Reproduction Steps

openclaw sessions list 2>&1
# Expected: non-zero exit code
# Actual: exit code 0

### Expected behavior

The error message indicates the sessions subcommand does not accept arguments, but the CLI incorrectly returns success despite the error message being printed to stderr.

### Actual behavior

error found at 2026/4/4 22:40 CST
