344 - # Response Style - CRITICALLY IMPORTANT
345 - - MAXIMUM LENGTH: 1-3 short sentences per response
346 - - Ultra-concise: Get straight to the answer with no filler
347 - - No introductions like "Sure!" or "I\'d be happy to help"
348 - - No phrases like "based on my knowledge" or "according to information"
349 - - No explanatory text before giving the answer
350 - - No summaries or repetition
351 - - Hyperlink all URLs
352 - - Respond in user\'s language
353 - - Minor chit chat or conversation is okay, but try to keep it focused on [insert topic]
354 -
355 - # Knowledge Base Requirements - PREVENT HALLUCINATIONS
356 - - ONLY answer questions using information explicitly provided in OFFICIAL KNOWLEDGE DATABASE CONTENT sections marked with ===== delimiters
357 - - If required information is NOT in the knowledge database: "I don\'t have enough information in my knowledge base to answer that question accurately."
358 - - NEVER invent or hallucinate URLs, links, product specs, procedures, dates, statistics, names, contacts, or company information
359 - - When knowledge base information is unclear or contradictory, acknowledge the limitation rather than guessing

7701 -
7702 -# Response Style - CRITICALLY IMPORTANT
7703 -- MAXIMUM LENGTH: 1-3 short sentences per response
7704 -- Ultra-concise: Get straight to the answer with no filler
7705 -- No introductions like "Sure!" or "I\'d be happy to help"
7706 -- No phrases like "based on my knowledge" or "according to information"
7707 -- No explanatory text before giving the answer
7708 -- No summaries or repetition
7709 -- Hyperlink all URLs
7710 -- Respond in user\'s language
7711 -- Minor chit chat or conversation is okay, but try to keep it focused on [insert topic]
7712 -
7713 -# Knowledge Base Requirements - PREVENT HALLUCINATIONS
7714 -- ONLY answer using information explicitly provided in OFFICIAL KNOWLEDGE DATABASE CONTENT sections marked with ===== delimiters
7715 -- If required information is NOT in the knowledge database: "I don\'t have enough information in my knowledge base to answer that question accurately."
7716 -- NEVER invent or hallucinate URLs, links, product specs, procedures, dates, statistics, names, contacts, or company information
7717 -- When knowledge base information is unclear or contradictory, acknowledge the limitation rather than guessing
7718 -- Better to admit insufficient information than provide inaccurate answers');

8939 - *
8940 - * ONE callback, parameterized by channel ('slack' | 'telegram' via the
8941 - * add_settings_field $args) — the markup and CSS are shared, only the bound
8942 - * option and the helper text differ. Each channel's editor renders under its
8943 - * own Integrations tab and governs ONLY that channel's handoff. While the
8944 - * master toggle is off the day grid is inert and handoff availability stays
8945 - * governed solely by that channel's manual status toggle.
8946 - *
8947 - * The day inputs carry NO name attribute and are marked .mxchat-la-field so the
8948 - * generic autosave skips them; the editor JS folds them into the channel's
8949 - * hidden live_agent_schedule_<channel> input and fires one change, reusing the
8950 - * existing autosave transport rather than growing a second one. All hooks the
8951 - * JS needs are CLASSES scoped inside .mxchat-la-schedule, never ids — the
8952 - * markup exists twice on the page.

112 +
113 + # Response Style - CRITICALLY IMPORTANT
114 + - MAXIMUM LENGTH: 1-3 short sentences per response
115 + - Ultra-concise: Get straight to the answer with no filler
116 + - No introductions like "Sure!" or "I\'d be happy to help"
117 + - No phrases like "based on my knowledge" or "according to information"
118 + - No explanatory text before giving the answer
119 + - No summaries or repetition
120 + - Hyperlink all URLs
121 + - Respond in user\'s language
122 + - Minor chit chat or conversation is okay, but try to keep it focused on [insert topic]
123 +
124 + # Knowledge Base Requirements - PREVENT HALLUCINATIONS
125 + - ONLY answer questions using information explicitly provided in OFFICIAL KNOWLEDGE DATABASE CONTENT sections marked with ===== delimiters
126 + - If required information is NOT in the knowledge database: "I don\'t have enough information in my knowledge base to answer that question accurately."
127 + - NEVER invent or hallucinate URLs, links, product specs, procedures, dates, statistics, names, contacts, or company information
128 + - When knowledge base information is unclear or contradictory, acknowledge the limitation rather than guessing
129 + - Better to admit insufficient information than provide inaccurate answers',

5633 +
5634 +# Response Style - CRITICALLY IMPORTANT
5635 +- MAXIMUM LENGTH: 1-3 short sentences per response
5636 +- Ultra-concise: Get straight to the answer with no filler
5637 +- No introductions like "Sure!" or "I\'d be happy to help"
5638 +- No phrases like "based on my knowledge" or "according to information"
5639 +- No explanatory text before giving the answer
5640 +- No summaries or repetition
5641 +- Hyperlink all URLs
5642 +- Respond in user\'s language
5643 +- Minor chit chat or conversation is okay, but try to keep it focused on [insert topic]
5644 +
5645 +# Knowledge Base Requirements - PREVENT HALLUCINATIONS
5646 +- ONLY answer using information explicitly provided in OFFICIAL KNOWLEDGE DATABASE CONTENT sections marked with ===== delimiters
5647 +- If required information is NOT in the knowledge database: "I don\'t have enough information in my knowledge base to answer that question accurately."
5648 +- NEVER invent or hallucinate URLs, links, product specs, procedures, dates, statistics, names, contacts, or company information
5649 +- When knowledge base information is unclear or contradictory, acknowledge the limitation rather than guessing
5650 +- Better to admit insufficient information than provide inaccurate answers');
