+description: Run E2E tests for Sentry JavaScript SDK test applications

+---
+
+# E2E Test Runner Skill
+
+This skill runs end-to-end tests for Sentry JavaScript SDK test applications. It ensures SDK packages are built before running tests.
+
+## Input
+
+The user provides a test application name and optionally a variant:
+
+- `e2e-tests/test-applications/nextjs-app-dir` (full path)
+- `nextjs-app-dir` (just the app name)
+- `nextjs-app-dir --variant nextjs-15` (with variant)
+
+## Workflow
+
+### Step 1: Parse the Test Application Name
+
+Extract the test app name from user input:
+
+- Strip `e2e-tests/test-applications/` prefix if present
+- Extract variant flag if provided (e.g., `--variant nextjs-15`)
+- Store the clean app name (e.g., `nextjs-app-dir`)
+
+### Step 2: Determine Which Packages Need Rebuilding
+
+If the user recently edited files in `packages/*`, identify which packages were modified:
+
+```bash
+# Check which packages have uncommitted changes (including untracked files)
+git status --porcelain | grep "^[ MARC?][ MD?] packages/" | cut -d'/' -f2 | sort -u
+```
+
+For each modified package, rebuild its tarball:
+
+```bash
+cd packages/<package-name>
+yarn build && yarn build:tarball
+cd ../..
+```
+
+**Option C: User Specifies Packages**
+
+If the user says "I changed @sentry/node" or similar, rebuild just that package:
+
+```bash
+cd packages/node
+yarn build && yarn build:tarball
+cd ../..
+```
+
+### Step 3: Verify Test Application Exists
+
+Check that the test app exists:
+
+```bash
+ls -d dev-packages/e2e-tests/test-applications/<app-name>
+```
+
+If it doesn't exist, list available test apps:
+
+```bash
+ls dev-packages/e2e-tests/test-applications/
+```
+
+Ask the user which one they meant.
+
+### Step 4: Run the E2E Test
+
+Navigate to the e2e-tests directory and run the test:
+
+```bash
+cd dev-packages/e2e-tests
+yarn test:run <app-name>
+```
+
+If a variant was specified:
+
+```bash
+cd dev-packages/e2e-tests
+yarn test:run <app-name> --variant <variant-name>
+```
+
+### Step 5: Report Results
+
+After the test completes, provide a summary:
+
+**If tests passed:**
+
+```
+✅ E2E tests passed for <app-name>
+
+All tests completed successfully. Your SDK changes work correctly with this test application.
+```
+
+**If tests failed:**
+
+```
+❌ E2E tests failed for <app-name>
+
+[Include relevant error output]
+```
+
+**If package rebuild was needed:**
+
+```
+📦 Rebuilt SDK packages: <list of packages>
+🧪 Running E2E tests for <app-name>...
+```
+
+## Error Handling
+
+- **No tarballs found**: Run `yarn build && yarn build:tarball` at repository root
+- **Test app not found**: List available apps and ask user to clarify
+- **Verdaccio not running**: Tests should start Verdaccio automatically, but if issues occur, check Docker
+- **Build failures**: Fix build errors before running tests
+
+## Common Test Applications
+
+Here are frequently tested applications:
+
+- `nextjs-app-dir` - Next.js App Router
+- `nextjs-15` - Next.js 15.x
+- `react-create-hash-router` - React with React Router
+- `node-express-esm-loader` - Node.js Express with ESM
+- `sveltekit-2` - SvelteKit 2.x
+- `remix-2` - Remix 2.x
+- `nuxt-3` - Nuxt 3.x
+
+To see all available test apps:
+
+```bash
+ls dev-packages/e2e-tests/test-applications/
+```
+
+## Example Workflows
+
+### Example 1: After modifying @sentry/node
+
+```bash
+# User: "Run e2e tests for node-express-esm-loader"
+
+# Step 1: Detect recent changes to packages/node
+# Step 2: Rebuild the modified package
+cd packages/node
+yarn build && yarn build:tarball
+cd ../..
+
+# Step 3: Run the test
+cd dev-packages/e2e-tests
+yarn test:run node-express-esm-loader
+```
+
+### Example 2: First-time test run
+
+```bash
+# User: "Run e2e tests for nextjs-app-dir"
+
+# Step 1: Check for existing tarballs
+# Step 2: None found, build all packages
+yarn build && yarn build:tarball
+
+# Step 3: Run the test
+cd dev-packages/e2e-tests
+yarn test:run nextjs-app-dir
+```
+
+### Example 3: With variant
+
+```bash
+# User: "Run e2e tests for nextjs-app-dir with nextjs-15 variant"
+
+# Step 1: Rebuild if needed
+# Step 2: Run with variant
+cd dev-packages/e2e-tests
+yarn test:run nextjs-app-dir --variant nextjs-15
+```
+
+## Tips
+
+- **Always rebuild after SDK changes**: Tarballs contain the compiled SDK code
+- **Watch build output**: Build errors must be fixed before testing
+
+## Integration with Development Workflow
+
+This skill integrates with the standard SDK development workflow:
+
+1. Make changes to SDK code in `packages/*`
+2. Run `/e2e <app-name>` to test your changes
+3. Fix any test failures
+
+The skill automates the tedious parts of:
+
+- Remembering to rebuild tarballs
+- Navigating to the correct directory
+- Running tests with the right flags

+## 10.37.0
+
+### Important Changes
+
+- **feat(core): Introduces a new `Sentry.setConversationId()` API to track multi turn AI conversations across API calls. ([#18909](https://github.com/getsentry/sentry-javascript/pull/18909))**
+
+  You can now set a conversation ID that will be automatically applied to spans within that scope. This allows you to link traces from the same conversation together.
+
+  ```javascript
+  import * as Sentry from '@sentry/node';
+
+  // Set conversation ID for all subsequent spans
+  Sentry.setConversationId('conv_abc123');
+
+  // All AI spans will now include the gen_ai.conversation.id attribute
+  await openai.chat.completions.create({...});
+  ```
+
+  This is particularly useful for tracking multiple AI API calls that are part of the same conversation, allowing you to analyze entire conversation flows in Sentry.
+  The conversation ID is stored on the isolation scope and automatically applied to spans via the new `conversationIdIntegration`.
+
+- **feat(tanstackstart-react): Auto-instrument global middleware in `sentryTanstackStart` Vite plugin ([#18844](https://github.com/getsentry/sentry-javascript/pull/18844))**
+
+  The `sentryTanstackStart` Vite plugin now automatically instruments `requestMiddleware` and `functionMiddleware` arrays in `createStart()`. This captures performance data without requiring manual wrapping.
+
+  Auto-instrumentation is enabled by default. To disable it:
+
+  ```ts
+  // vite.config.ts
+  sentryTanstackStart({
+    authToken: process.env.SENTRY_AUTH_TOKEN,
+    org: 'your-org',
+    project: 'your-project',
+    autoInstrumentMiddleware: false,
+  });
+  ```
