Tips & Tricks

  1. 01
    Validate before copying

    If the input parser reports an error, fix the source value first instead of copying a partial result into code, config, or documentation.

  2. 02
    Keep secrets local

    The tool runs in your browser, but you should still avoid pasting long-lived production secrets into any shared or screen-recorded session.
