-name: File Size Check
-# Trigger the workflow on PRs to the main branch. It builds the extension in prod mode and checks the size of the
-# vsix file and webview bundle file and compares it with the main branch. It fails if the size has increased by more than 10%.
-# For vsix, we also check if the size is greater than 25MB.
+name: PR Checks
+# Trigger the workflow on PRs to the main branch.

+# 1. Calculate the size difference between the webview bundles of the main branch and the PR branch.
+# 2. Calculate the size difference between the VSIX files of the main branch and the PR branch.
+# 3. Does a check if the PR has properly localized strings.

+                * If there are changes in localized strings in `package.nls.json`, make sure that `src/localization/xliff/vscode-mssql.xlf` is updated.
