4 use cases

  • Fix failing tests in a repo from the terminal

    Point FuXi at a repository with failing tests and have it read, edit, and rerun until they pass.

    View prompt
    In the repository at <repo-path>, run FuXi from the terminal with the prompt 'Fix the failing tests in this repository.' Expected output: a summary of the files FuXi changed and the result of its test run. Verify by running the project's own test command yourself and confirming the previously failing tests now pass.

  • Run FuXi on your own provider key and switch models

    Connect your own API key and change models with /model to manage which provider handles your work.

    View prompt
    Configure the FuXi repo at fuxicodex/Fuxi to use the API key for <provider-name> from the local environment, then start a session. Expected output: FuXi starts and answers a short test prompt using the provider you set. Verify that the request is billed to your own provider account and not to FuXi-managed models.

  • Set up FuXi on a headless machine with a setup token

    Authenticate FuXi on a server or CI runner without an interactive sign-in using a setup token.

    View prompt
    On the headless host <host-name>, install FuXi from the fuxicodex/Fuxi repo and authenticate with `fuxi setup-token`. Expected output: `fuxi doctor` completes its environment checks without errors. Verify by running `fuxi --version` and confirming the version prints.

  • Run FuXi with bypassed approvals inside a container

    Let FuXi run tool calls without prompts, but only inside a disposable container or VM.

    View prompt
    Inside a disposable container or VM, install FuXi from fuxicodex/Fuxi and start it with `fuxi --dangerously-skip-permissions` in the repository at <repo-path>. Expected output: the session starts in bypassPermissions mode and completes the requested change. Verify by checking the diff in the repository and confirming nothing outside the sandbox changed.
