 - Bundled using a custom JavaScript bundler that inlines local `require()` calls
 - Executed in GitHub Actions using `actions/github-script@v8`
 
+### Top-Level Script Pattern
+
+Top-level `.cjs` scripts (those that are executed directly in workflows) follow a specific pattern:
+
+**✅ Correct Pattern - Export main, but don't call it:**
+```javascript
+async function main() {
+  // Script logic here
+  core.info("Running the script");
+}
+
+module.exports = { main };
+```
+
+**❌ Incorrect Pattern - Don't call main in the file:**
+```javascript
+async function main() {
+  // Script logic here
+  core.info("Running the script");
+}
+
+await main(); // ❌ Don't do this!
+
+module.exports = { main };
+```
+
+**Why this pattern?**
+- The bundler automatically injects `await main()` during inline execution in GitHub Actions
+- This allows the script to be both imported (for testing) and executed (in workflows)
+- It provides a clean separation between module definition and execution
+- It enables better testing by allowing tests to import and call `main()` with mocks
+
+**Examples of top-level scripts:**
+- `create_issue.cjs` - Creates GitHub issues
+- `add_comment.cjs` - Adds comments to issues/PRs
+- `add_labels.cjs` - Adds labels to issues/PRs
+- `update_project.cjs` - Updates GitHub Projects
+
+All of these files export `main` but do not call it directly.
