What it is
WhatsApp Group Summary Bot is a bot designed for the Hermes Agent that records all messages in a WhatsApp group and generates structured summaries twice daily (07:00 and 23:00 WIB) in casual Indonesian. It operates with silent recording, activating on mentions or slash commands, and provides optional Roast mode.
How it works
The system records group messages to per-group JSONL logs, then cron jobs generate summaries from the collected logs. It patches several components: the bridge allows messages from all group members, the WhatsApp adapter disables group whitelist filtering, and an explicit log routine writes group messages to JSONL (ts, sender, body). Cron jobs deliver summaries to a specified group at 07:00 and 23:00 WIB. Environment variable WHATSAPP_REQUIRE_MENTION=true is used to gate bot responses in groups.

Caveats
License is listed as MIT in the README badge, but the repository metadata shows license: none listed. The installation notes include patches that are overwritten by Hermes updates, requiring re-application after updates. The setup requires Hermes Agent and WhatsApp gateway; changing patches may affect behavior. Logs are stored per group in JSONL format under the user’s home directory.
