codewhale-hq/Codewhale ? reverse-engineered prompt

Build me a terminal based coding agent called Codewhale that can read a local project, edit files, run commands, and check its own work.

I want an interactive CLI experience first, with a simple text UI, plus a headless command for one shot tasks like fixing tests or making small changes from a script. It should support signing in or using a local model, and let me switch models easily. I also want basic safety controls, like asking before risky actions, a plan mode that only explores, and a way to see what files and commands were used.

If it makes sense, include support for plugins or external tools so it can connect to things like MCP servers, and make it possible to review a pull request too. Keep it local first, easy to run on my machine, and use current docs online if you need to check anything that has changed.
