@sentry/junior-agent-browser

@sentry/junior-agent-browser adds browser automation and visual QA workflows to Junior via the agent-browser CLI.

Install it alongside @sentry/junior:

pnpm add @sentry/junior @sentry/junior-agent-browser

Add the package name to the plugin set exported from plugins.ts:

import { defineJuniorPlugins } from "@sentry/junior";

export const plugins = defineJuniorPlugins(["@sentry/junior-agent-browser"]);

The package includes three skills:

• /agent-browser for general browser navigation, interaction, extraction, and capture
• /visual-web-qa for evidence-driven verification of frontend, docs, layout, theme, loading, animation, and interaction changes
• /demo-video for edited demos, walkthroughs, and explainers with browser captures, optional narration and music, and Remotion

For example:

/visual-web-qa Verify the docs theme on desktop and mobile, then share the evidence.

/demo-video captures the production workflow; it does not install Remotion or FFmpeg. Use a local artifact project with compatible dependencies and an appropriate Remotion license. For generated narration, enable a TTS plugin such as @sentry/junior-tts, or supply an audio file. Keep video artifacts separate from the app unless a repository change is requested.
