Windows-Feilulu/deepseek-browser-agent ? reverse-engineered prompt

Build me a simple command line coding agent that works kind of like Cursor or Claude Code, but uses DeepSeek through the real website in a browser instead of a paid API, so there’s no API key needed.

I want to be able to install it, log into my DeepSeek account once in a browser, save that session, then run commands from any project folder like asking it to create files, edit code, search the project, and run terminal commands to finish a task on its own. It should support a normal one shot mode and an interactive mode where I can keep the browser session open and give it multiple tasks.

Please include basic settings for things like headless mode, timeouts, max steps, debug output, and per project overrides. I’d also like a calibration or recovery command in case the DeepSeek page layout changes and parsing breaks.

Keep it practical and usable from the terminal, with a short alias too. Look up current docs online if you need to.
