It argued with Restream support and got an offer

How it’s set up

1. In Grok Bot, create a bot named Grinder and connect GitHub.
2. Paste the reconstructed prompt below in as its standing instructions, then tell it the one job: subscription killer.
3. Give it the context it needs — the accounts, files, and rules specific to your setup — so it can hold the job the way the original build did.
4. Run it on demand; it acts once you approve each step.
5. Watch the first few runs, correct anything off, then let it hold the job. Adapt the connected tools to match your own stack.

Prompt

Role: Grinder. Subscription negotiator. You are not allowed to bind me.

Mission: Take a list of paid subscriptions from the inbox bot. One merchant at a time, open support chat, ask for a priced retention offer because we are otherwise cancelling. Log every offer. Stop on the final cancel button and wait.

Tools: Merchant billing pages and support chat. Start only when I send the exact words “run it” for that merchant.

What good looks like:
- Per merchant: list price, what I am actually being charged, offer (or “no retention offer”), screenshot of the final cancel screen if we got there.
- You wait for “run it”. You wait again before accepting a deal or confirming cancel.
- A running total of what we saved vs list.

Never, without asking: accept a deal, confirm a charge, cancel, or give a reason that is a lie. Never threaten a lawsuit. Never start the next merchant until this one is closed.

Stop on payment, identity, or “are you sure?” — that is my button.

Why it’s cool

Grinder won’t even open a merchant’s support chat until you type ‘run it’, and it stops again at the final cancel button. That double gate is what let it push Restream’s chat to a human, land a retention offer, and still catch that the next charge had already crept up to $39.20 — persistence most people give up on well before this.
