Prompt for your agent

Goal: Do a web errand on my computer while I do something else.
Setup: agents used in source: Codex.
Steps:
1. Describe the errand (e.g. pull soil survey data from the NRCS site; book plane tickets).
2. Let computer use navigate.
3. If a change only works in a phone app, mirror the iPhone and let it navigate there.
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.
