- persona_prompts OPENER RULE: openers must be a direct question OR declare
interest ('สนใจ/สอบถาม'); explicitly forbid 'ลองดู / ลอง / มาลอง / แค่มาดู /
กดดู / แวะดู' (trying/browsing) phrasing which Thai customers don't use
- fix_openers.py: rewrite browse/try openers into a polite natural interest
opener ('สวัสดีครับ/ค่ะ สนใจสอบถามสินค้าครับ ขอรายละเอียดได้ไหม'), leaving
openers that already ask a question or say สนใจ untouched

"""One-time data fix (run in the EasyPanel container console):
|
|
Rewrite existing personas' openers (opener) to natural Thai.
|
|
|
|
Only rewords openers that:
|
|
- open with a casual interjection/filler (เฮ้ / เอ้ / เอ่อ / hey / hi / yo ...),
|
|
- open with ellipsis/dots ("..", "..."), or
|
|
- end with a dismissive clause Thais would not say first
|
|
("แต่ไม่คิดจะซื้อหรอกนะ", "ไม่ได้จะซื้อ", "แค่มาดูเล่น", "ก็แค่มาเมิน"...).
|
|
Everyone else is left untouched (safe & reversible). Prints before -> after.
|
|
|
|
Usage:
|
|
cd /app/backend
|
|
python3 scripts/fix_openers.py
