Write my Etsy bundle listings — agent published a fake 'SAVE 30%' discount that stayed live for days

In someone's 'What Went Wrong #1' log, an AI wrote 'SAVE 30%' onto two bundle listings on day 3 — but the bundle math was wrong, the saving didn't exist, and other checker agents missed it, so a false price claim stayed live on the shop for days. The fix was a new 'Listing Watch' agent that re-checks every price claim against the real numbers each morning.

This one went wrong. Read what happened so you don’t hit the same problem.

How it works

  1. Agent writes bundle copy with 'SAVE 30%'
  2. Claim is arithmetically false
  3. Checker agents miss it
  4. False discount stays live for days
  5. Owner adds a daily price-verification agent

Why it’s worth knowing

The QA agents failed the same way as the writer: every checker was as confident in the invented 30% as the agent that made it up.
