+            Write an exciting, polished GitHub release body for vscode-latex ${{ inputs.tag }} and save it to `release-notes.md`.
+
+            vscode-latex is a VS Code extension providing rich LaTeX support — syntax highlighting, snippets, and language features for authoring LaTeX documents directly in VS Code.
+
+            Steps:
+            1. Run `git describe --tags --abbrev=0 HEAD^` to get the previous tag, then run `git log <previous-tag>..HEAD --oneline` to see all commits in this release.
+            2. Read `src/` source files and `README.md` to understand the extension's features.
+            3. Write the release body to `release-notes.md`. It should:
+               - Open with an enthusiastic one-paragraph summary of what's new or why this release is exciting.
+               - Have clearly labelled sections (e.g. **✨ New Features**, **🐛 Bug Fixes**, **⚡ Improvements**) — only include sections that actually have content.
+               - End with an installation note pointing to the VS Code Marketplace.
+               - Be written in an upbeat, developer-friendly tone — celebrate the work!
+            Do NOT publish it yourself — a subsequent step will do that.
