michaelshimeles/ralphy ? reverse-engineered prompt

Build me a command line tool called Ralphy that takes a single task or a whole PRD file and keeps running AI coding agents on it until the work is finished.

I want it to work from the terminal, with a simple command like ralphy "add login button" or ralphy --prd PRD.md, and it should support reading tasks from markdown, yaml, json, or GitHub issues. It should be able to use different AI tools like Claude Code, Codex, OpenCode, Cursor, Qwen, Droid, and the others, with Claude as the default.

Please also make it able to run tasks in parallel using separate branches or worktrees, keep track of progress, and optionally create PRs. Add a way to save project rules and commands in a config file, plus support browser automation for testing flows when needed. If you need to, look up the current docs for the agent CLIs online so the integrations are accurate.
