Message routing can be split up into the routing of incoming and outgoing messages.
Incoming messages
- connections receive envelopes which they deposit in inbox
- agent loop's react picks envelopes off the inbox
- tries to decode the message; errors are handled by the error skill
- messages are dispatched to all relevant handlers
Outgoing messages
- skills deposit messages in outbox
-
outbox constructs an envelope from the message
-
multiplexer assigns messages to relevant connection based on three rules:
- checks if envelope context exists and uses that
- checks if default routing applies
-
sends to default connection
-
connections can encode envelopes where necessary
