+# Build Configuration
+# ------------------
+# The build config defines what gets packaged into your agent's Docker image.
+# This same configuration is used whether building locally or remotely.
+#
+# When building:
+# 1. All files from include_paths are collected into a build context
+# 2. The context is filtered by dockerignore rules
+# 3. The Dockerfile uses this context to build your agent's image
+# 4. The image is pushed to a registry and used to run your agent
+build:
+  context:
+    # Root directory for the build context
+    root: ../ # Keep this as the default root
+
+    # Paths to include in the Docker build context
