For a MIP model experiment description in GMD the following applies.
When we say "available" we mean either included as part of the paper or the supplement, or uploaded to a persistent public repository with a unique identifier.

1. The boundary conditions must be fully described and any required data made available.
I think this is fulfilled in Table 2

2. Baseline required model outputs should be indicated, with variables, length of averaging and length of output.
I think this is fulfilled in Table 3

3. There should be in place a mechanism for making the model outputs available.
It is less clear to me whether this has been fulfilled to the GMD standard.
a. When I click on the link in the Data availability section it does not resolve
b. Rather than appearing in the data availability section in passive voice, the information should be in the Outputs section and presented in the form of positive instructions to anyone wanting to participate.

Other things.

If you think there is any chance that you might change the protocol in any way while still remaining in the TRAPPIST-1 project, you should add a version number to the name of the protocol and include this in the title. Changes to the protocol cannot be written as an erratum to the paper, but must be submitted as a new paper, ie. these changes comprise are an update not an error.

Figure 1
Has it been adjusted as suggested by the reviewer or was the comment about there being no dynamic sea ice supposed to be an answer to the reviewer's suggestion?

Radiative equilibrium.
While it is OK if different model groups have different criteria, you should request any important criteria like this to be reported as part of the information about the model outputs. As a frequent user of MIP outputs I can tell you that it is a really good idea as part of the outputs to include information about each model, how it was set up, and a contact person who is prepared to answer questions about it. Some projects even get their members to write individual papers about how the runs were set up. Anyway, you should specify what you require in the new paragraph of the Outputs section of the paper where you are going to address the mechanism for making outputs available.

Global Climate Model
Pick one rather than pick and mix. :-)

Thanks for the revisions! Hope the project is super-successful!
