Live-test showed Grok 4.1 Fast inventing 'mcp_mychatarchive_search_brain' when asked about Telegram chat history. Fix: - Tool descriptions explicitly say 'TELEGRAM' and 'NICHT ChatGPT/Memory/RAG' - SYSTEM_PROMPT_EXTRA lists all 4 exact tool names and forbids inventing alternatives like 'mychatarchive' or 'search_brain' - Forbids using rag_search/openmemory_search/web_search for Telegram- related queries - Demands honest 'no data' over hallucination

"""Hausmeister-Bot tool — read access to the chatlogger SQLite database.

|
This file is INSTALLED into /opt/homelab-ai-bot/tools/chatlog.py
|
|
(autodiscovered by tool_loader.py). It does NOT need a restart of the
|
|
chatlogger bot — it only reads from the shared SQLite file
|
|
(/opt/chatlogger/chats.db) using the Store class from the chatlogger
|
|
package, which sits next to the hausmeister-bot in the same repo.
|
|
|
|
Three LLM-callable functions:
|
|
- chatlog_list_chats() → enumerate known group chats
|
|
- chatlog_recent(limit, chat) → most recent N messages
|
|
- chatlog_search(query, chat) → FTS5 search across messages
|
|
- chatlog_since(minutes, chat) → time window

TELEGRAM-MITSCHNITT (chatlog_*-Tools — DAS WICHTIGSTE):
|
|
|
|
Es gibt einen passiven Mitleser-Bot (@arakawa_concierge_bot), der bestimmte
|
|
Telegram-Gruppen-Chats LIVE aufzeichnet und in einer SQLite-DB speichert.
|
|
Z.B. die Airbnb-Concierge-Gruppe fuer die ARAKAWA-Wohnungen in Phnom Penh
|
|
(G2010B im 20. Stock, D1603 im 16. Stock).
|
|
|
|
→ Diese Tools heissen GENAU SO und sind die EINZIGEN richtigen fuer
|
|
Fragen zum Telegram-Verlauf:
|
|
chatlog_list_chats
|
|
chatlog_recent
|
|
chatlog_search
|
|
chatlog_since
|
|
|
|
→ NIEMALS Tool-Namen erfinden wie "mychatarchive", "search_brain",
|
|
"telegram_history". Diese existieren NICHT. Wenn du etwas Aehnliches
|
|
meinst, nutze chatlog_search.
|
|
|
|
→ NIEMALS rag_search, openmemory_search, memory_read oder web_search
|
|
fuer Telegram-Verlaufs-Fragen verwenden — die kennen den Telegram-Chat
|
|
NICHT.
|
|
|
|
Trigger-Phrasen die ZWINGEND chatlog_*-Tools ausloesen:
|
|
- "Telegram-Chat" / "Telegram-Gruppe" / "im Chat" / "in der Gruppe"
|
|
- "Chatverlauf" / "Chatverlaeufe" / "Verlauf"
|
|
- "Concierge" / "Bnb" / "Airbnb" / "Listing" / "Vermietung"
|
|
- "Wohnung G2010B" / "G 210" / "D1603" / "ARAKAWA-Wohnung"
|
|
- "aktueller Stand" zu Vermietung/Wohnung/Concierge
|
|
- "wer hat was zugesagt" / "was ist offen" / "muss ich reagieren"
|
|
- "was wurde zuletzt geschrieben" / "was war heute"
|
|
|
|
Vorgehen:
|
|
1. Wenn unklar welche Gruppe → chatlog_list_chats() ZUERST.
|
|
2. Sonst direkt chatlog_recent(chat="<title-substring>") oder
|
|
chatlog_search(query="...", chat="<title-substring>").
|
|
3. Antwort zitiert KONKRET: Datum, Absender, Inhalt.
|
|
4. Wenn Tool nichts liefert → ehrlich sagen "keine Daten in der DB",
|
|
NICHT halluzinieren.
