In an example embodiment, a method of resolving source code changes is provided. It is determined whether there are any portions of source code dependent on a changed portion of source code. Then, for each portion of source code including the changed portion of source code and portions of source code dependent on the changed portion of source code, one or more pieces of metadata for the portion of source code are obtained, a danger score for the portion of source code is calculated based on the one or more pieces of metadata, an execution rule corresponding to the danger score is retrieved, and the execution rule is executed, causing a command to be executed on an external run-time component.
