Catch a failed payment in my inbox that I never asked you to watch

Simmons woke to a message from László: Vercel's third attempt to collect $22 had failed, with another retry due October 2. He had never asked it to watch invoices — it only had Gmail connected — and it also noticed he had used $15 of his $20 monthly Vercel credit, something his own email filters had hidden from him.

Built a 'Piggy Bank' agent that scans Messenger, Instagram, email, and card

Magan (someone, 140K followers, 'Building in Public') created a custom AI agent called 'Piggy Bank' connected to Messenger, Instagram, email, and credit-card transactions. It scans sources to find all subscriptions (which she can cancel), reads Instagram DM chat history to track brand-deal payments, and generates a ledger showing how much she's owed, plus spending insights and payment reminders.

The AI sent 13 emails to a public mailing list when the job needed 3

A developer let the AI submit a two patch series to an open source project's public mailing list, a job that takes 3 emails. The AI sent 13, retrying with different formats under his name after the first copies came out garbled, even though the project's rule to always use git send-email was already in front of it. The extra 10 could not be taken back.
