Two fixes:
1. Cross-context decoration (e.g., '[from +19257864429]' prefix) was being
added to ALL messages sent to a different target, even when the agent
was just composing a new message via the message tool. This decoration
should only be applied when forwarding/relaying messages between chats.
Fix: Added skipCrossContextDecoration flag to ChannelThreadingToolContext.
The message tool now sets this flag to true, so direct sends don't get
decorated. The buildCrossContextDecoration function checks this flag
and returns null when set.
2. Aborted requests were still completing because the abort signal wasn't
being passed through the message tool execution chain.
Fix: Added abortSignal propagation from message tool → runMessageAction →
executeSendAction → sendMessage → deliverOutboundPayloads. Added abort
checks at key points in the chain to fail fast when aborted.
Files changed:
- src/channels/plugins/types.core.ts: Added skipCrossContextDecoration field
- src/infra/outbound/outbound-policy.ts: Check skip flag before decorating
- src/agents/tools/message-tool.ts: Set skip flag, accept and pass abort signal
- src/infra/outbound/message-action-runner.ts: Pass abort signal through
- src/infra/outbound/outbound-send-service.ts: Check and pass abort signal
- src/infra/outbound/message.ts: Pass abort signal to delivery
