Define how agents should handle messages referencing context
from other sessions (CLI/XMPP/WeChat channel switching).
- SOUL.md: new section 五 on session bridging
- agentmemory: saved as shared architecture rule
- SESSION-BRIDGE-PROTOCOL.md: full protocol doc
Define code+LLM collaboration protocol for group chat participation:
- Code layer: no @mention gate, forward all msgs to LLM
- LLM layer: output __SILENT__ (discard) or __REPLY__ (send)
- Documented in MEMORY.md (LLM prompt) and AgentsMeeting (shared ref)
- Update xmpp_bot.py to remove @mention gate
