Overview

Arbiter decides which agents will actually respond from the qualified candidates. This implements “floor control” - preventing multiple agents from responding simultaneously.

Strategies:

  • all: All candidates respond (original behavior)

  • primary_first: Primary agent responds, others only if primary unavailable

  • round_robin: Rotate between agents for each message

  • bid: Select agent based on relevance score (expertise matching)

  # Review feedback is forced routing: the Matcher already restricts candidates
  # to the quoted comment's author, the sole agent ReviewHandler will accept.
  # Floor-control arbitration (bid scoring, round_robin) among a forced single
  # recipient is meaningless, and a low bid score must not drop it (e.g. bid
  # strategy with bid_fallback_enabled: false) or the Review button no-ops.
