Set it up

  1. Define the job

    Say exactly what you want done and what the agent may and may not do on your behalf.

  2. Share only what is needed

    Give Hermes Agent the minimum files or access required. Avoid sharing passwords in chat when a safer login flow exists.

  3. Review the plan

    Ask the agent to show its plan or draft before it acts, and approve each step that has real consequences.

  4. Check the result

    Confirm the outcome yourself (order placed, request sent, document understood) and keep a record.

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.
