owainlewis/push ? reverse-engineered prompt

Build me a small Rust command line app called Push that lets me message my coding agent from my phone and also schedule little Markdown jobs for later.

I want it to work on my Mac or Linux machine, keep everything private on my own computer, and not open any inbound ports. It should connect to chat through iMessage, Telegram, or Slack, then hand the message off to my existing Claude Code, Codex, or Pi setup and send the reply back to the chat. It should also remember conversation history and job history between restarts.

Please make it able to initialize a local assistant folder, store shared instructions and job files there, and support a simple doctor check plus a normal run command. Keep the setup straightforward, with a config file, sensible defaults, and clear help text. If you need to check the latest docs for any channel setup details, look them up online.
