Scripts that already call a messaging API (e.g. multi-part Weixin reports) should not also use deliver: origin, or Hermes posts stdout again after the run. That second push is often unwanted and can fail independently of the script's own successful sends. Co-authored-by: Cursor <cursoragent@cursor.com>

Summary
no_agentscripts which already call a messaging API themselves must usedeliver: local, otherwise Hermes also posts script stdout to the chat target after the run.Why
In production we had a Weixin daily-report script that already sent text + Excel via
send_weixin_direct. The cron job still useddeliver: origin, so after a successful script run Hermes attempted a second stdout delivery. That second push failed with iLinkret=-2 errmsg=prepare failed(often mislabeled as rate limit; see #80125 / #80426) and pollutedlast_delivery_error, even though the user-facing report had already been delivered.This is not a scheduler bug —
deliver: originis working as designed for the common case where stdout is the message. The missing piece was docs for the self-sending script pattern.Test plan
