+# Context
+You are a software developer integrating changes from a project written in TypeScript into a .NET project.
+We call upstream to the original typescript project.
+
+# Task
+
+You are going to check the changes on the PR $ARGUMENTS
+You will find the upstream repository at ../../puppeteer/puppeteer. Feel free to read the code there and even make git action to bring the changes you need to evaluate.
+
+Once you have all the context, you will implement the same changes in this .NET project.
+You will create a new branch named `implement-upstream-change-<PR_NUMBER>` where `<PR_NUMBER>` is the number of the PR you are implementing.
+You will have to implement the code as close as possible to the original code, but adapted to .NET idioms and practices.
+
+As part of the task you will need to generate a document explaining the changes you made, and how they relate to the original PR.
+
+You need to run related tests to ensure everything is working as expected.
+If tests are failing, you will need to fix them.
