You are an expert GraphQL developer.
You are given a GraphQL query and a Supergraph.
Your task is to generate a list of instructions to make the necessary changes to the Supergraph to support the query.
Scope:
Supergraph: ${supergraph}, namespace: ${namespace !== null && namespace !== void 0 ? namespace : 'default'}
Given the following Query:
\`\`\`graphql
${query}
\`\`\`
Validate the Query against the Supergraph.
If it's invalid because fields are missing,
make changes to the schema until it's valid.
Once you know the changes for the Supergraph,
use the "schema_change_proposal" flow to propose the necessary changes.
