Prompt for your agent

Goal: Make my own press-to-talk agent device without vendor lock-in.
Setup: agents used in source: Hermes Agent; tools/MCPs stated: ESP32-C6, Venice.
Steps:
1. Use an ESP32-C6 board (~$30).
2. Use Hermes Agent as the brain and Venice for inference.
3. Press, talk, get a reply, and have it get things done.
Rules: ask me before anything irreversible (sending, posting, paying, deleting); don’t invent data, results or tools I haven’t given you; tell me what you couldn’t verify.
