WhatsApp and WeChat (Weixin/iLink) both deliver messages individually
without any client-side batching, so rapid multi-message bursts (forwarded
batches, paste-splits, etc.) each trigger a separate agent invocation.
This wastes tokens (redundant system prompts / context for each fragment)
and degrades UX (the user receives reply fragments instead of a single
coherent response).
Both adapters now mirror the Telegram adapter's proven text-debounce
pattern:
- _text_batch_delay_seconds / _text_batch_split_delay_seconds
(configurable via env vars)
- _pending_text_batches dict for per-session aggregation
- _enqueue_text_event() concatenates successive TEXT messages and
resets the flush timer
- _flush_text_batch() dispatches after the quiet period expires
Configurable via env vars:
HERMES_WHATSAPP_TEXT_BATCH_DELAY_SECONDS (default 5.0)
HERMES_WHATSAPP_TEXT_BATCH_SPLIT_DELAY_SECONDS (default 10.0)
HERMES_WEIXIN_TEXT_BATCH_DELAY_SECONDS (default 3.0)
HERMES_WEIXIN_TEXT_BATCH_SPLIT_DELAY_SECONDS (default 5.0)
