-### What the script does
-
-**Step 1 — Create a sandbox.** `Sandbox.create()` spins up a fresh Linux environment via the E2B API. The `timeoutMs` / `timeout` sets a 5-minute auto-destroy limit so forgotten sandboxes don't run up costs.
-
-**Step 2 — Clone the PR branch.** `sandbox.git.clone()` clones the repository inside the sandbox, not on the CI runner. The `GITHUB_TOKEN` provided by GitHub Actions authenticates the clone when paired with `x-access-token` as the username — this is the standard [GitHub Apps authentication pattern](https://docs.github.com/en/apps/creating-github-apps/authenticating-with-a-github-app/authenticating-as-a-github-app-installation). `depth: 1` makes it a shallow clone for speed.
-
-**Step 3 — AI code review.** `sandbox.commands.run()` executes `git diff` inside the sandbox and returns the output in `stdout`. The diff is then sent to an LLM (OpenAI GPT-4o in this example) with a system prompt asking for a code review. You can swap this for any model or provider — see [Connect LLMs](/docs/quickstart/connect-llms).
-
-**Step 4 — Run tests.** The test suite runs inside the sandbox with `onStdout` / `on_stdout` callbacks that stream output in real time to the GitHub Actions logs. The `commands.run()` method throws when a command exits with a non-zero code — `CommandExitError` in JavaScript, `CommandExitException` in Python — so test failures are caught with try/catch and cause the workflow to fail.
-
-**Step 5 — Post results.** The review is posted as a PR comment via the [GitHub REST API](https://docs.github.com/en/rest/issues/comments#create-an-issue-comment). The `GITHUB_TOKEN` has write access thanks to the `permissions` block in the workflow. Finally, `sandbox.kill()` destroys the sandbox immediately rather than waiting for the timeout.
+1. **Create sandbox** — `Sandbox.create()` spins up an isolated Linux environment with a 5-minute timeout
+2. **Clone the PR** — `sandbox.git.clone()` checks out the PR branch using `x-access-token` + `GITHUB_TOKEN` for [authentication](https://docs.github.com/en/apps/creating-github-apps/authenticating-with-a-github-app/authenticating-as-a-github-app-installation)
+3. **AI review** — runs `git diff` inside the sandbox, sends the output to an LLM — swap the model for any provider via [Connect LLMs](/docs/quickstart/connect-llms)
+4. **Run tests** — `commands.run()` streams output in real time and throws on failure (`CommandExitError` / `CommandExitException`)
+5. **Post results** — comments the review on the PR via the GitHub REST API, then destroys the sandbox
