    Usage: cli.py --pr-url=<URL on supported git hosting service> <command> [<args>].
    For example:
    - cli.py --pr_url=... review
    - cli.py --pr_url=... describe
    - cli.py --pr_url=... improve
    - cli.py --pr_url=... ask "write me a poem about this PR"
    - cli.py --pr_url=... reflect
    - cli.py --issue_url=... similar_issue

    Supported commands:
    - review / review_pr - Add a review that includes a summary of the PR and specific suggestions for improvement.

    - ask / ask_question [question] - Ask a question about the PR.

    - describe / describe_pr - Modify the PR title and description based on the PR's contents.

    - improve / improve_code - Suggest improvements to the code in the PR as pull request comments ready to commit.
    Extended mode ('improve --extended') employs several calls, and provides a more thorough feedback

    - reflect - Ask the PR author questions about the PR.

    - update_changelog - Update the changelog based on the PR's contents.

    - add_docs

    - generate_labels


    Configuration:
    To edit any configuration parameter from 'configuration.toml', just add -config_path=<value>.
    For example: 'python cli.py --pr_url=... review --pr_reviewer.extra_instructions="focus on the file: ..."'
