setup

Cloud Operator plugin setup

Run the checks below, fix what you can, and end with a status table. Ask the user only when a step needs them. None of the checks need the gcloud binary (Antigravity reads ADC itself); when a fix needs gcloud, tell the user to run it in their own terminal.

1. Default project

Read the active gcloud configuration's project from its config file:

CFG="${CLOUDSDK_CONFIG:-$HOME/.config/gcloud}"; echo "${CLOUDSDK_CORE_PROJECT:-$(sed -n 's/^project *= *//p' "$CFG/configurations/config_${CLOUDSDK_ACTIVE_CONFIG_NAME:-$(cat "$CFG/active_config" 2>/dev/null || echo default)}" 2>/dev/null)}"

If it's empty, the user runs gcloud config set project <project-id> (the project their Operator agent lives in, or will live in); until then, ask them which project to use.

2. ADC file and quota project

Read only the type and quota_project_id fields of the ADC file. Never print the whole file: it contains a refresh token. If the command below prints nothing, treat it as no quota project; don't open the file any other way.

ADC="${GOOGLE_APPLICATION_CREDENTIALS:-${CLOUDSDK_CONFIG:-$HOME/.config/gcloud}/application_default_credentials.json}"
if [ -f "$ADC" ]; then grep -oE '"(type|quota_project_id)": *"[^"]*"' "$ADC"; else echo NO_ADC_FILE; fi

• NO_ADC_FILE → the user runs gcloud auth application-default login, then restarts Antigravity.
• No quota_project_id → the user runs gcloud auth application-default set-quota-project <project-id> (needs serviceusage.services.use on that project), then restarts Antigravity.

3. Smoke test

Check that an MCP server whose name ends in autocloud is connected and lists ask_cloud_operator. If not, turn the plugin on in /plugin (a new install can start disabled), check ... > MCP Servers, and restart Antigravity.

Call ask_cloud_operator with project set to projects/<default project> and userQuery set to Hello. In two sentences, confirm which project you are operating in and list the capabilities you offer. Expect a reply and a context_id; the first call can take 1-3 minutes while a sandbox warms up. Then call search_operator_sessions for the same project; the hello session should be the newest by createTime.
