+| Name  | Description | Default Value |
+| :------------- | :------------- | :------------- |
+| <a id="swift_common.extract_symbol_graph-actions"></a>actions |  The object used to register actions.   |  none |
+| <a id="swift_common.extract_symbol_graph-compilation_contexts"></a>compilation_contexts |  A list of `CcCompilationContext`s that represent C/Objective-C requirements of the target being compiled, such as Swift-compatible preprocessor defines, header search paths, and so forth. These are typically retrieved from the `CcInfo` providers of a target's dependencies.   |  none |
+| <a id="swift_common.extract_symbol_graph-feature_configuration"></a>feature_configuration |  The Swift feature configuration.   |  none |
+| <a id="swift_common.extract_symbol_graph-include_dev_srch_paths"></a>include_dev_srch_paths |  A `bool` that indicates whether the developer framework search paths will be added to the compilation command.   |  none |
+| <a id="swift_common.extract_symbol_graph-minimum_access_level"></a>minimum_access_level |  The minimum access level of the declarations that should be extracted into the symbol graphs. The default value is `None`, which means the Swift compiler's default behavior should be used (at the time of this writing, the default behavior is "public").   |  `None` |
+| <a id="swift_common.extract_symbol_graph-module_name"></a>module_name |  The name of the module whose symbol graph should be extracted.   |  none |
+| <a id="swift_common.extract_symbol_graph-output_dir"></a>output_dir |  A directory-type `File` into which `.symbols.json` files representing the module's symbol graph will be extracted. If extraction is successful, this directory will contain a file named `${MODULE_NAME}.symbols.json`. Optionally, if the module contains extensions to types in other modules, then there will also be files named `${MODULE_NAME}@${EXTENDED_MODULE}.symbols.json`.   |  none |
+| <a id="swift_common.extract_symbol_graph-swift_infos"></a>swift_infos |  A list of `SwiftInfo` providers from dependencies of the target being compiled. This should include both propagated and non-propagated (implementation-only) dependencies.   |  none |
