Mission Instructions

1. Install Google Cloud SDK

Install gcloud.

2. Authenticate Google Cloud

Authenticate gcloud with Application Default Credentials:

gcloud auth application-default login --billing-project=YOUR_PROJECT_ID

Find your Project ID in the Google Cloud console (ensure billing is enabled). For in-person workshops, use your provided lab account and project ID.

3. Install Antigravity

Install Antigravity 2.0 (or alternatively, the Antigravity CLI). It is not recommended to use Antigravity IDE because it does not support using Antigravity through Agent Platform.

4. Configure and Authenticate Antigravity

When logging in, choose Continue with Google Cloud or Use business account, and specify your billing project. If an error appears saying that no license is available, choose Use Agent Platform instead (the provided lab projects do not have an individual subscription).

5. Confirm Account and Plan in Settings

In Antigravity settings, confirm that you are logged in correctly and on the right plan. For in-person workshops, verify that your account shows the provided credentials and the "Agent Platform" plan to prevent any unexpected costs.

6. Solve Mission with Antigravity

Open the directory where you put the starter code from the previous mission and ask Antigravity:

Read the sample code in this directory. Run uv init to setup the project. Adapt the flight computer and complete the missions T0-01 and T0-02

Note: If you have trouble installing the tools locally, use Cloud Shell in the Google Cloud console.
