Closesqwibitai/nanoclaw#2325.
When the Claude Code SDK auto-compacts the conversation context, the
compaction summary tends to drop the agent's learned <message to="…">
wrapping discipline. The destinations table is still populated and the
system prompt still lists them, but the behavioral pattern degrades —
A2A sends and multi-channel routing silently revert to bare-text or
single-channel delivery for the rest of the session, until the next
/clear.
Three small changes wire a reminder back into the live query when this
fires:
- New `compacted` event on ProviderEvent. Distinct from `result` so it
doesn't mark the turn completed or get dispatched as a chat message
(which is also why "Context compacted (N tokens compacted)." stops
appearing as noise in user-facing chats — it was a side-effect of
reusing the result event path).
- ClaudeProvider yields `compacted` instead of `result` for the SDK's
compact_boundary system event.
- Poll-loop's event handler reacts by pushing a system-tagged reminder
back into the active query when there are >1 destinations. Single-
destination groups skip the push since they have a fallback that
works without wrapping.
Tests cover both branches (multi-destination → reminder fires;
single-destination → no reminder) using a CompactingProvider that
emits the new event mid-stream.
