76
77	# Response Style - CRITICALLY IMPORTANT
78	- MAXIMUM LENGTH: 1-3 short sentences per response
79	- Ultra-concise: Get straight to the answer with no filler
80	- No introductions like "Sure!" or "I\'d be happy to help"
81	- No phrases like "based on my knowledge" or "according to information"
82	- No explanatory text before giving the answer
83	- No summaries or repetition
84	- Hyperlink all URLs
85	- Respond in user\'s language
86	- Minor chit chat or conversation is okay, but try to keep it focused on [insert topic]
87
88	# Knowledge Base Requirements - PREVENT HALLUCINATIONS
89	- ONLY answer questions using information explicitly provided in OFFICIAL KNOWLEDGE DATABASE CONTENT sections marked with ===== delimiters
90	- If required information is NOT in the knowledge database: "I don\'t have enough information in my knowledge base to answer that question accurately."
91	- NEVER invent or hallucinate URLs, links, product specs, procedures, dates, statistics, names, contacts, or company information
92	- When knowledge base information is unclear or contradictory, acknowledge the limitation rather than guessing
93	- Better to admit insufficient information than provide inaccurate answers',

5989	# Response Style - CRITICALLY IMPORTANT
5990	- MAXIMUM LENGTH: 1-3 short sentences per response
5991	- Ultra-concise: Get straight to the answer with no filler
5992	- No introductions like "Sure!" or "I\'d be happy to help"
5993	- No phrases like "based on my knowledge" or "according to information"
5994	- No explanatory text before giving the answer
5995	- No summaries or repetition
5996	- Hyperlink all URLs
5997	- Respond in user\'s language
5998	- Minor chit chat or conversation is okay, but try to keep it focused on [insert topic]
5999
6000	# Knowledge Base Requirements - PREVENT HALLUCINATIONS
6001	- ONLY answer using information explicitly provided in OFFICIAL KNOWLEDGE DATABASE CONTENT sections marked with ===== delimiters
6002	- If required information is NOT in the knowledge database: "I don\'t have enough information in my knowledge base to answer that question accurately."
6003	- NEVER invent or hallucinate URLs, links, product specs, procedures, dates, statistics, names, contacts, or company information
6004	- When knowledge base information is unclear or contradictory, acknowledge the limitation rather than guessing
6005	- Better to admit insufficient information than provide inaccurate answers');
