Problem

openclaw cron add --help outputs essentially empty/minimal help text — it does not list available parameters or their usage.

This forces users to guess parameter names through trial and error:

$ openclaw cron add --schedule "0 21 * * *" --system-event "test"
error: unknown option '--schedule'

$ openclaw cron add --target main --cron "0 21 * * *"
error: unknown option '--target' (Did you mean '--agent'?)

$ openclaw cron add --payload-text-file ./msg.txt
error: unknown option '--payload-text-file'

$ openclaw cron add --text "hello"
error: unknown option '--text'

After ~6 attempts, the correct invocation turned out to be:

openclaw cron add --name "job-name" --cron "0 21 * * *" --tz "Asia/Shanghai" --system-event "message content"

Expected behavior

openclaw cron add --help should list all accepted parameters with descriptions, at minimum:

• --name — job name
• --cron — cron expression
• --tz — timezone
• --system-event — the message/prompt text
• --agent — target agent (if applicable)

Environment
