AI Summary: Implement a pre-commit hook for the Llama Stack project to enforce the presence of the `upload-time` field in the `uv.lock` file. This will prevent unnecessary diffs and reduce the burden on code reviewers by ensuring consistency in the project's configuration files.

AI Summary: The task is to modify the 'check-workflows-use-hashes' pre-commit check within the Llama Stack project. The current implementation outputs errors in a non-standard format. The goal is to refactor the check to utilize GitHub's workflow command output format, enabling errors to be displayed directly on the code page within GitHub's pull request interface, improving the user experience for developers submitting pull requests.

AI Summary: Automate the update of Llama Stack's model listings by creating a weekly CI job that checks each provider's model list (likely via their APIs or web scraping) and updates the `models.py` files accordingly. This avoids manual updates and ensures the list remains current.

AI Summary: Standardize error messages for unsupported models in the Llama Stack framework. Currently, some providers return a simple `ValueError`, while others provide a more informative error including a list of supported models. The task involves modifying the error handling within Llama Stack to consistently return the more descriptive error message listing supported models when an unsupported model is specified.
