Prompt for your agent

Goal: Build my own replacement for an expensive desktop app.
Setup: agents used in source: Codex.
Steps:
1. Start with the core features you use.
2. Feed user feedback from every channel back into the agent.
3. Keep iterating feature parity.
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.
