Prompt for your agent

Goal: Run an agent with native phone functions on a basic phone.
Setup: agents used in source: Codex; tools/MCPs stated: DeepSeek API.
Steps:
1. Study the firmware and boot process; get custom code running in RAM through an existing app entry point (Calculator) without flashing.
2. Turn it into a chat app that sends messages to a model API and maps tool calls to phone functions: answer questions, battery, torch, call, alarm.
3. Trace the firmware’s response callbacks when requests go out but answers don’t come back.
4. Use a coding agent (here Codex) to help build; test on the handset.
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.
