+'@pandacss/extractor': patch
+---
+
+Add `endLineNumber` and `endColumn` fields to AST JSON output from `panda debug` command.
+
+The `*.ast.json` files generated by `panda debug` now include complete position information for detected CSS usage locations. Previously, only start position (`line` and `column`) was exported. Now the output includes:
+
+- `line`: Start line number
+- `column`: Start column number
+- `endLineNumber`: End line number (new)
+- `endColumn`: End column number (new)
+
+This provides complete span coverage for each detected node, making it easier to precisely locate CSS usage in source files.
+
+Fixes #3407
