Problem

iMessage reflects outbound agent messages back as inbound user messages (with control-char prefixes in some cases), causing echo reply loops. Closes openclaw#59363 upstream.

Root cause

resolveIMessageInboundDecision had a special path for self-chat where is_from_me=true messages would only be dropped if the echo-cache matched. When the cache missed (e.g. empty sentText on media-only sends, or control-char prefixed reflections), the message passed through as a user message and triggered another agent reply.

Fix

Drop all is_from_me messages unconditionally — matching the behaviour that already existed for non-self-chat DMs and groups. The selfChatCache.remember() call is preserved so the subsequent is_from_me=false SQLite reflection is still caught by the selfChatCache.has() check.

Files changed

• extensions/imessage/src/monitor/inbound-processing.ts: collapse self-chat branch into unconditional drop
