+# Sentry.io Integration
+
+MyCoder CLI now includes integration with Sentry.io for error tracking and monitoring.
+
+## How It Works
+
+The Sentry.io integration is initialized at the start of the CLI application to capture any errors that occur during execution. This helps us identify and fix issues more quickly.
+
+## Installation
+
+The Sentry Node SDK is included as a dependency in the CLI package:
+
+```bash
+npm install @sentry/node --save
+```
+
+## Configuration
+
+By default, Sentry is:
+- Enabled in production environments
+- Disabled in development environments (unless explicitly enabled)
+- Configured to capture 100% of transactions
+
+### Environment Variables
+
+You can control Sentry behavior with the following environment variables:
+
+- `NODE_ENV`: Set to "production" to enable Sentry (default behavior)
+- `ENABLE_SENTRY`: Set to "true" to explicitly enable Sentry in any environment
+- `SENTRY_DSN`: Override the default Sentry DSN (optional)
+
+### Command Line Options
+
+You can also configure Sentry through command-line options:
+
+```bash
+# Use a custom Sentry DSN
+mycoder --sentryDsn="https://[email protected]/project"
+```
+
+## Version Tracking
+
+All errors reported to Sentry include the package version information in the format `[email protected]`. This allows us to trace errors to specific releases and understand which versions of the software are affected by particular issues.
+
+## Implementation Details
+
+The Sentry SDK is initialized as early as possible in the application lifecycle:
+
+```javascript
+import * as Sentry from '@sentry/node';
+import { createRequire } from 'module';
+
+// Initialize Sentry with version information
+Sentry.init({
+  dsn: 'https://2873d2518b60f645918b6a08ae5e69ae@o4508898407481344.ingest.us.sentry.io/4508898476687360',
+  tracesSampleRate: 1.0,
+  environment: process.env.NODE_ENV || 'development',
+  release: `mycoder@${packageVersion}`,
+  enabled: process.env.NODE_ENV !== 'development' || process.env.ENABLE_SENTRY === 'true',
+});
+
+// Capture errors
+try {
+  // Application code
+} catch (error) {
+  Sentry.captureException(error);
+}
+```
+
+## Testing Sentry Integration
+
+A hidden command is available to test the Sentry integration:
+
+```bash
+mycoder test-sentry
+```
+
+This command will:
+1. Generate a test error that includes the package version
+2. Report it to Sentry.io
+3. Output the result to the console
+
+Note: In development environments, you may need to set `ENABLE_SENTRY=true` for the test to actually send data to Sentry.
+
+## Privacy
+
+Error reports sent to Sentry include:
+- Stack traces
+- Error messages
+- Environment information
+- Release version
+
+Personal or sensitive information is not intentionally collected. If you discover any privacy concerns with the Sentry integration, please report them to the project maintainers.
