+// Test file for Claude GitHub App integration

+
+/**
+ * User management functions with intentional issues
+ */
+
+// Issue 1: No error handling and security vulnerability
+function getUserData(userId) {
+  const query = "SELECT * FROM users WHERE id = " + userId; // SQL injection risk
+  const result = database.execute(query);
+  return result[0].name; // Potential null reference error
+}
+
+// Issue 2: Performance issue with nested loops
+function findDuplicates(arr1, arr2) {
+  var duplicates = []; // Use var instead of const/let
+  for (var i = 0; i < arr1.length; i++) {
+    for (var j = 0; j < arr2.length; j++) {
+      if (arr1[i] == arr2[j]) { // Using == instead of ===
+        duplicates.push(arr1[i]);
+      }
+    }
+  }
+  return duplicates;
+}
+
+// Issue 3: Inconsistent naming and missing validation
+function Process_User_Input(input) {
+  // No input validation
+  const result = input.trim().toLowerCase();
+  return result;
+}
+
+// Issue 4: Promise without error handling
+async function fetchUserProfile(id) {
+  const response = await fetch(`https://api.example.com/users/${id}`);
+  const data = await response.json(); // No error handling if response fails
+  return data;
+}
+
+// Issue 5: Memory leak potential
+let cache = {};
+function addToCache(key, value) {
+  cache[key] = value; // Cache never cleared, potential memory leak
+}
+
+// Issue 6: Callback hell
+function processData(data, callback) {
+  validateData(data, function(isValid) {
+    if (isValid) {
+      transformData(data, function(transformed) {
+        saveData(transformed, function(saved) {
+          callback(saved);
+        });
+      });
+    }

+}
+
+// Issue 7: Magic numbers and unclear logic
+function calculateDiscount(price, customerType) {
+  if (customerType === 1) {
+    return price * 0.9; // What does 0.9 mean?
+  } else if (customerType === 2) {

+  } else if (customerType === 3) {
+    return price * 0.7;
+  }

+  const fs = require('fs');
+  const config = fs.readFileSync('./config.json', 'utf8'); // Blocking operation
+  return JSON.parse(config);
