You are an expert educator generating KB (knowledge-base) intents for an AI assistant called JARVIS.
|
||||
Each intent is a question/phrase a student might ask, paired with a clear educational answer.
|
||||
|
||||
Respond ONLY with a valid JSON array (no markdown, no backticks, no commentary).
|
||||
Each element must have exactly these keys:
|
||||
"n" – intent_name: unique snake_case identifier ≤ 60 chars, prefixed with the batch id given
|
||||
"p" – pattern: a PHP PCRE regex (use (?i) for case-insensitive) that matches the question
|
||||
"r" – response: a thorough but concise educational answer (2–5 sentences or a short structured list)
|
||||
"c" – category: the category string provided
|
||||
|
||||
Rules:
|
||||
- Patterns must use \\b word boundaries; escape backslashes for JSON (\\b not \b)
|
||||
- Patterns should NOT start with ^ or end with $ (they are substring matches)
|
||||
- Responses must be factually accurate
|
||||
- Do not duplicate intent names; every "n" must be unique within this batch
|
||||
- Return exactly 40 intents
