feat(think): configurable messenger concurrency strategy (#2313) by threepointone · Pull Request #2354 · cloudflare/agents

threepointone · 2026-09-24T01:07:58Z

New messengerConcurrency property picks the Chat SDK concurrency strategy for messenger replies. It accepts any ConcurrencyStrategy ("queue", "burst", "debounce", "drop" or "concurrent") or a ConcurrencyConfig. The default, exported as DEFAULT_MESSENGER_CONCURRENCY, is the existing { strategy: "burst", debounceMs: 600 }, so behavior does not change.

One Chat instance serves every messenger on an agent, so the setting is per agent. It must be a class field, because the runtime reads it before onStart.

Test: under "queue", the first message of a burst is answered on its own right away, and every line is still answered. Under the default burst strategy, the first prompt would be all three lines joined. The test fails when the runtime ignores the setting.

Closes #2313
Closes #1946

Docs: a new "Change the Concurrency Strategy" section in docs/think/messengers.md.
