Prompts to start from

These are the reusable prompts from real cases. Swap in your own details, run it once on something low-stakes, and read what the agent did before you trust it.

Home/family task: order family groceries from fridge contents. Keep changes reversible and ask before messages, payments, or deletes.

Manage my side of this insurance claim: index the policy and receipts, track adjuster messages, flag delays versus promises, and draft challenge letters. Do not file complaints or send mail until I approve.

Tools that show up most

Custom agent (12), Claude Code (8), Claude (7), n8n (7), Grok Bot (5), Claude Cowork (4).

Guardrails

Keep the agent in 'propose, don't pay' mode: let it gather numbers and draft messages, and approve any payment or account change yourself.

Where it went wrong, or nearly did

• Fill forms and review tax filings: A review of a tax filing uncovered a significant error from the computer-use agent.
