Bug type
Behavior bug (incorrect output/state without crash)
Summary
CLI commands with --json flag (e.g. openclaw agents list --json) mix plugin loading logs into stdout alongside the JSON output, making it impossible to pipe the result to jq or parse programmatically.
Steps to reproduce
$ openclaw agents list --json
[plugins] feishu_doc: Registered feishu_doc, feishu_app_scopes
[plugins] feishu_chat: Registered feishu_chat tool
[plugins] feishu_wiki: Registered feishu_wiki tool
[plugins] feishu_drive: Registered feishu_drive tool
[plugins] feishu_bitable: Registered bitable tools
[
{
"id": "work",
...
}
] Piping to jq fails:
$ openclaw agents list --json | jq '.[0].id'
parse error (Invalid numeric literal at line 1, column 2)
2>/dev/null does not help because the [plugins] lines go to stdout, not stderr.
Expected behavior
--json output should be valid JSON on stdout. All log/diagnostic messages should go to stderr.
Actual behavior
Plugin subsystem info-level logs ([plugins] Registered ...) are written to stdout via console.log(), appearing before the JSON array and corrupting the output.

Operating system
macOS 14.5 (Darwin 23.5.0)
Install method
npm global
Model
openai/claude-opus-4.5
Provider / routing chain
N/A — this bug is in CLI output, not model routing
Additional provider/model setup details
Feishu plugin is loaded from /opt/homebrew/lib/node_modules/openclaw/extensions/feishu.
The plugin loading logs are emitted via createSubsystemLogger("plugins").info(), which routes to console.log() (stdout).
The codebase already has routeLogsToStderr() (sets loggingState.forceConsoleToStderr = true) but it is not called in --json code paths.
Suggested fix: in the CLI preAction hook, if any parsed option is --json, call routeLogsToStderr() so stdout stays clean for JSON output.
Logs, screenshots, and evidence
Impact and severity
Affected: all users piping --json output programmatically
Severity: medium (functional breakage of --json flag purpose)
Frequency: 100% reproducible when plugins are loaded
Workaround: openclaw agents list --json | grep -v '^\[plugins\]'
Additional information
Affected commands include at minimum agents list --json and agents bindings --json, likely all commands offering --json. The fix should be applied globally in the preAction hook rather than per-command.
