File the bug and let the agent show its work. With visual previews on, the pull request opens with a capture of the fixed screen, and every follow-up commit brings a fresh one. You see the result before you read a line of the diff.
Visual previews are opt-in per repository. Pick images, video, or both, and write capture instructions such as the pages and viewports to show.
Upload credentials and the .propr/workflow.yml overrides live in the visual previews docs.
Describe what looks wrong and where, as you would for a teammate. Start it as a New Task, or add ProPR's trigger label to a GitHub issue; the agent works in an isolated workspace.
After the fix, the agent decides whether the result shows on screen. When it does, it runs the project's own tooling, such as Playwright, Storybook, or an emulator, and captures the changed state: up to eight images or videos, each with a title and a note. Captures never enter your Git history. A backend-only change gets none, and a blocked capture names the tool the agent image lacks.
The pull request description ends in a Visual preview section. Compare the capture with the bug report, then read the diff with the result already in mind.
Comment on the PR, or run /fix on a /review's findings. The completion comment for that commit carries its own captures, focused on what the follow-up changed.
Fixed on phones. At 768 px the Pay button now sits too far from the total; align them on one row.

On public propr #2952, Claude Opus 5.5 fixed truncated labels in the Agent Tank sidebar. The PR description ends with the before/after capture and the agent's note.
![Public ProPR pull request 2952 on GitHub, merged: the title [2948 by Claude Opus 5.5] Agent Tank sidebar truncates Antigravity window labels, and the propr-dev description shortened to its implementation summary, ending in a Visual preview section with a before/after capture of the Agent Tank sidebar Usage block and the agent's note.](../../assets/screenshots/derived/github-2952-visual-preview-mobile@2x.png)
A follow-up gets its own capture. On public propr #2874, the completion comment for commit 118c55b shows the New automation form after the change.
A pull request that opens with a picture of the fix, a fresh capture with every follow-up commit, and the code review in the same thread.
Checkout total wraps under the Pay button on phones
At 390 px the order total drops to a second line and the Pay button covers it. Keep the total on one line.
