Simon Willison has detailed a method for efficiently caching tools installed via `uvx` within GitHub Actions workflows. By setting the `UV_EXCLUDE_NEWER` environment variable to a specific date, subsequent `uvx` commands will only install versions released up to that point. This approach prevents repeated downloads from the Python Package Index (PyPI) for each workflow run, saving time and resources. The cache can be updated by simply advancing the date in the environment variable, allowing for controlled upgrades of the tools. AI
