+# PointCloud Operations Skill
+
+## Overview
+This skill provides guidance for developing and testing PointCloud operations in CloudPointRPC.
+
+## Key Guidelines
+1. **Source Code**: `src/cloud_point/point_cloud_builder.cpp` and `include/cloud_point/point_cloud_builder.hpp`.
+2. **Reprojection**: Stereo images are converted into 3D points via `cv::reprojectImageTo3D`.
+3. **Verification**: Run unit tests using `build/tests/unit_tests --gtest_filter=*PointCloud*`.
