+          You are running inside the copilot-sdk-java repository.
+          The code generator has just run and produced Java source files under
+          src/generated/java/com/github/copilot/sdk/generated/rpc/.
+
+          Your task is to spot-check the generated API classes against the source
+          JSON schema to verify the generator produced correct output.
+
+          **Critical constraint: Do NOT modify any files. This is a read-only
+          verification. Use only read/inspect operations.**
+
+          **Steps:**
+          1. Read the API schema at:
+             scripts/codegen/node_modules/@github/copilot/schemas/api.schema.json
+
+          2. Pick these 3 generated API classes to verify:
+             - src/generated/java/com/github/copilot/sdk/generated/rpc/SessionToolsApi.java
+             - src/generated/java/com/github/copilot/sdk/generated/rpc/SessionUiApi.java
+             - src/generated/java/com/github/copilot/sdk/generated/rpc/SessionPermissionsApi.java
+
+          3. For each class, verify:
+             - Every RPC method in the schema's corresponding namespace has a
+               matching Java method in the generated class
+             - Parameter record fields match the JSON schema property names
+             - Java types are consistent with JSON schema types (String for
+               "string", Integer/int for "integer", Boolean/boolean for
+               "boolean", List for "array", Map or a generated class for
+               "object", etc.)
+             - No extra methods exist in the Java class that are not in the
+               schema
+
+          4. Print a summary table of what was checked and the result for each
+             method.
+
+          5. If ANY mismatch is found, print the details and exit with a
+             non-zero code.
+             If all checks pass, print "Schema verification passed" and exit 0.
