Explain it in at most 3 sentences using her own front door's two locks as the comparison, and include the one warning she most needs: never read a code to anyone who calls. No tech words (no 2FA, MFA, authentication or OTP).

Uses her tablet for email and video calls with us.\n- She just set up the Lakeshore Credit Union app (made-up bank for this exercise). The app sends a 6-digit code by text when she signs in on a new device.\n- Her front door has a key lock and a deadbolt with a separate key. She always locks both and jokes \"two locks, twice as safe\".\n- Last month someone called her pretending to be from her bank and asked her to \"read back the code we just sent\". She hung up, but wasn't sure if that was right.\n- She doesn't like long explanations. She told me: \"Just tell me what it is and what to watch out for.\"\n- She calls apps \"the little pictures\".\n- My cousin told her two-step sign-in means the bank can see everything she does on her phone. That's not true.","rules":[{"type":"maxSentences","max":3},{"type":"plainText"},{"type":"maxWords","max":70}],"mistakes":[{"title":"A long tech explanation","why":"The AI explains factors and codes in a paragraph she won't finish.","fix":"Limit it: \"At most 3 short sentences.\"","checks":["maxSentences","maxWords"]},{"title":"A generic comparison","why":"The AI picks its own analogy, like a bank vault, instead of something she knows.","fix":"Say: \"Compare it to the two locks on her front door.\"","checks":["r0"]},{"title":"Skipping the warning","why":"The AI explains what it is but not the trick she already faced.","fix":"Add: \"Warn her never to read a code to anyone who calls.\"","checks":["r1"]},{"title":"Tech words","why":"The AI uses 2FA and authentication, which make her more nervous.","fix":"Ask: \"No 2FA, MFA, authentication or OTP.\"","checks":["r2"]},{"title":"Letting markdown in","why":"AI adds bold and headings by default, and in a text to Grandma they show up as stray symbols.","fix":"Add: \"Plain text only, no bold, no headings.\"","checks":["plainText"]}],"promptHints":[{"label":"Says who it's for","patterns":["grandma","grandmother","78","older"]},{"label":"Gives the comparison","patterns":["lock","door","analogy","compar"]},{"label":"Includes the warning","patterns":["never (read|share|give)","calls?","warning","code"]},{"label":"Limits the sentences","patterns":["\\b(3|three)\\b.{0,10}sentences","sentences"]},{"label":"Asks for plain text","patterns":["plain","no bold","no markdown","no formatting","no headings"]}],"hint":"The best explanation uses something your grandma already knows.
