Set it up

  1. Map the task

    Write the trigger, the inputs, the decisions and the output. Note which steps need a human yes.

  2. Connect the tools

    Set up Claude, OpenAI Codex, Antigravity, Android with the narrowest permissions that work. Use a test account or sandbox first.

  3. Build the workflow

    Create the steps in order. Add an approval step before anything sends, pays or deletes.

  4. Run it on real but low-stakes data

    Run a few times, read every output, and fix prompts or rules that misfire.

  5. Schedule and monitor

    Turn on the schedule or trigger, and add a daily summary or alert so you notice failures.

Copy the full setup prompt

Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.

Please:
1. Ask me 3 short questions about my situation (accounts I have, budget, what I want the output to look like).
2. Propose a step-by-step plan using these tools or cheaper alternatives, with the time and cost of each step. Use official pricing pages; say "check pricing" if unsure.
3. Then do the setup with me one step at a time, waiting for my OK before anything that sends messages, posts publicly, spends money or deletes data.
4. Finish with a checklist to run it again next time.
