# Proof via Cursor

> Get device-backed proof on every PR from your existing CI, without installing the Revyl GitHub App

The easiest way to get [Proof of Changes](/agents/proof) running is the [GitHub App](/integrations/github). This guide covers the alternative: setting up Proof of Changes with a Cursor Automation when you can't install the GitHub App, or you use a different SCM provider.

Prompt for your coding agent:

```text
Get Revyl proof of changes on this repository's pull requests through Cursor, from its existing CI.

Read https://docs.revyl.com/integrations/cursor/proof.md and follow it. It's the current Revyl guide for this, so prefer it over anything you remember about Revyl.

Add `revyl build upload` right after the CI step that builds the simulator `.app` or debug `.apk`, and keep `REVYL_API_KEY` in CI secrets. I'll create the Cursor Automation myself.

You're done when a pull request's CI uploads its build to Revyl.

Ask me before anything that needs my login or approval.
```

## Who this is for

This guide is for teams that:

- Already build every PR in their own CI (GitHub Actions or equivalent)
- Already use Cursor Automations
- Want a device-backed proof comment on the PR
- Haven't connected the Revyl GitHub App yet

## What happens on each PR

```text
CI builds the app
  → Uploads the build to Revyl: revyl build upload
  → Cursor Automation starts
  → Matches Revyl build for the PR head SHA
  → Starts the Revyl session: revyl device start
  → Captures screenshots + validations
  → Saves the session URL
  → Comments on the PR with the collected information
```

If no matching build exists, the Automation comments that proof was not run and stops — it never rebuilds and never claims proof without a device session.

## Getting started

### 1. Install Revyl in Cursor

Install the [Revyl plugin](/integrations/cursor) and authenticate.

### 2. Add an upload step to CI

After your existing build produces a simulator `.app` or installable `.apk`,
upload it. In a GitHub Actions job:

```yaml
- name: Install Revyl CLI
  run: |
    curl -fsSL https://revyl.com/install.sh | sh
    echo "$HOME/.revyl/bin" >> "$GITHUB_PATH"

- name: Upload build to Revyl
  run: |
    revyl build upload \
      --file path/to/app.apk \
      --app "<your-app-id>" \
      --platform android \
      --version "$PR_HEAD_SHA" \
      --yes \
      --json
  env:
    REVYL_API_KEY: ${{ secrets.REVYL_API_KEY }}
    PR_HEAD_SHA: ${{ github.event.pull_request.head.sha || github.sha }}
```

In a pull request job, the upload goes to the pull request's source branch. On
another CI, run the same command with the pull request's head commit as
`--version`, and see
[Choose where CI uploads go](/builds/ci-builds#choose-where-ci-uploads-go) for
where its uploads land.

See the ready-made [`upload-for-cursor-proof.yml`](https://github.com/RevylAI/revyl-cli/blob/main/examples/ci-github-actions/upload-for-cursor-proof.yml) workflow in the public CLI examples. It stores `REVYL_API_KEY` as a CI secret and the app id as a variable; GitHub Actions metadata (`scm_head_sha`, PR number, and related fields) is stamped automatically so the Automation can match the build to the commit.

### 3. Enable the Cursor Automation

Create an Automation at [cursor.com/automations](https://cursor.com/automations):

1. Paste the prompt from
   [`PROMPT.md`](https://github.com/RevylAI/revyl-cli/blob/main/examples/cursor-automation/prove-mobile-pr/PROMPT.md).
2. Enable **Comment on pull request** and **shell**. Do not enable Revyl MCP.
3. Trigger **CI completed** / **Workflow run completed** on the upload job. Do
   not use Pull request pushed as the default.
4. Add secret `REVYL_API_KEY` and variable `REVYL_APP_ID`.
