The 'make install-fission-cli' step is redundant since the Fission CLI is already installed in the previous step. This duplication could cause confusion or unexpected behavior.

Suggested change

make install-fission-cli

The Archive step should use 'if: ${{ failure() }}' instead of 'if: ${{ always() }}' to only upload artifacts when there's actually a failure, matching the original workflow behavior.

Suggested change

	if: ${{ always() }}
	if: ${{ failure() }}
