# Rhodawk AI — Local gRPC Stub Generator
# ----------------------------------------------------------------------------
# Resolves W-001 (CRITICAL): the openclaude_grpc/openclaude_pb2.py and
# openclaude_grpc/openclaude_pb2_grpc.py files are NOT committed to source
# (they are generated at Docker build time). This script generates them
# locally so app.py can be imported and run without a full Docker build.
#
# Usage:
#   bash scripts/generate_stubs.sh
#
# Requirements:
#   pip install grpcio-tools
