+### Integration Tests
+
+In addition to unit tests, we have integration tests that use the compiled binary to test against live endpoints:
+
+```shell
+# Build the binary first
+make build
+
+# Run integration tests
+cd integration
+go test -v
+```
+
+Integration tests are located in the `integration/` directory and automatically skip tests requiring authentication when no GitHub token is available. See `integration/README.md` for more details.

+# Integration Tests
+
+This directory contains integration tests for the `gh-models` CLI extension. These tests are separate from the unit tests and use the compiled binary to test actual functionality.
+
+## Overview
+
+The integration tests:
+- Use the compiled `gh-models` binary (not mocked clients)
+- Test basic functionality of each command (`list`, `run`, `view`, `eval`)
+- Are designed to work with or without GitHub authentication
+- Skip tests requiring live endpoints when authentication is unavailable
+- Keep assertions minimal to avoid brittleness
+
+## Running the Tests
+
+### Prerequisites
+
+1. Build the `gh-models` binary:
+   ```bash
+   cd ..
+   script/build
+   ```
+
+2. (Optional) Authenticate with GitHub CLI for full testing:
+   ```bash
+   gh auth login
+   ```
+
+### Running Locally
+
+From the integration directory:
+```bash
+go test -v
+```
+
+Without authentication, some tests will be skipped:
+```
+=== RUN   TestIntegrationHelp
+--- PASS: TestIntegrationHelp (0.05s)
+=== RUN   TestIntegrationList
+    integration_test.go:90: Skipping integration test - no GitHub authentication available
+--- SKIP: TestIntegrationList (0.04s)
+```
+
+With authentication, all tests should run and test live endpoints.
+
+## CI/CD
+
+The integration tests run automatically on pushes to `main` via the GitHub Actions workflow `.github/workflows/integration.yml`.
+
+The workflow:
+1. Builds the binary
+2. Runs tests without authentication (tests basic functionality)
+3. On manual dispatch, can also run with authentication for full testing
+
+## Test Structure
+
+Each test follows this pattern:
+- Check for binary existence (skip if not built)
+- Check for authentication (skip live endpoint tests if unavailable)
+- Execute the binary with specific arguments
+- Verify basic output format and success/failure
+
+Tests are intentionally simple and focus on:
+- Commands execute without errors
+- Help text is present and correctly formatted
+- Basic output format is as expected
+- Authentication requirements are respected
+
+## Adding New Tests
+
+When adding new commands or features:
+1. Add a corresponding integration test
+2. Follow the existing pattern of checking authentication
+3. Keep assertions minimal but meaningful
+4. Ensure tests work both with and without authentication
