## What it does

This skill runs a visual QA pass on a web app without leaving Cursor. It leans on the built-in `cursor-ide-browser` MCP, which can open URLs, take screenshots, read console messages, inspect network requests and interact with page elements.

The flow: make sure the dev server is up, and if it is not, start it in the background with `npm run dev` and wait for the localhost line. Then `browser_navigate` opens the route, `browser_take_screenshot` captures the full page, `browser_console_messages` surfaces errors like `TypeError`, `ReferenceError` or React hydration mismatches, and `browser_network_requests` shows 4xx/5xx codes, CORS failures and duplicate calls. When the change touches buttons, forms or modals, `browser_click`, `browser_fill` and `browser_hover` drive the interaction and you screenshot again.

Before clicking anything, the skill advises calling `browser_snapshot` to get correct element refs. `browser_resize` covers responsive checks, and `browser_navigate` with `position: "side"` puts the browser next to your code. One catch: the whole thing depends on Cursor's built-in browser, so in other editors you would repeat these steps by hand.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill visual-qa-testing -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/visual-qa-testing/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/visual-qa-testing/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill visual-qa-testing -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/visual-qa-testing/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill visual-qa-testing -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/visual-qa-testing/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install spencerpauly/awesome-cursor-skills visual-qa-testing
```

2. **Manually: put the files in place**
- File: `.github/skills/visual-qa-testing/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill visual-qa-testing -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/spencerpauly/awesome-cursor-skills --path resources/visual-qa-testing
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/visual-qa-testing/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill visual-qa-testing -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/spencerpauly/awesome-cursor-skills/tree/HEAD/resources/visual-qa-testing/SKILL.md

## When to use it
- check how a page renders after a layout change
- catch JavaScript errors in the console before shipping
- spot failed API calls and 4xx/5xx responses
- test a button, form or modal by clicking it in the browser
- view the page at a different viewport size

## Example prompts
- run a visual QA pass on the home page and show me the screenshot
- check the console and network requests on /settings after my edits
- click the save button and screenshot the result

# Visual QA

Use this skill after making UI changes to visually verify the result, catch console errors, and audit network requests — all without leaving Cursor.

## How It Works

Cursor has a built-in browser (`cursor-ide-browser` MCP) that can navigate to URLs, take screenshots, read console messages, inspect network requests, and interact with page elements. This skill uses those tools to do a quick visual QA pass.

## Steps

1. **Ensure the dev server is running** — check if there's already a terminal running the dev server. If not, start one in the background:

   ```bash
   npm run dev
   ```

   Wait for the server to be ready (watch for the "ready" or localhost URL in the output).

2. **Navigate to the page** — use `browser_navigate` to open the relevant page:

   ```
   Tool: browser_navigate
   Arguments: { "url": "http://localhost:3000", "take_screenshot_afterwards": true }
   ```

   If the change is on a specific route, navigate directly to it (e.g., `/settings`, `/dashboard`).

3. **Take a screenshot** — capture the current state:

   ```
   Tool: browser_take_screenshot
   Arguments: { "fullPage": true }
   ```

   Review the screenshot for visual issues: layout breaks, missing content, wrong colors, misaligned elements.

4. **Check console for errors** — look for JavaScript errors or warnings:

   ```
   Tool: browser_console_messages
   ```

   Report any errors, especially `TypeError`, `ReferenceError`, failed imports, or React hydration mismatches.

5. **Audit network requests** — check for failed API calls or unexpected requests:

   ```
   Tool: browser_network_requests
   ```

   Look for: 4xx/5xx status codes, CORS errors, excessively large responses, unnecessary duplicate requests.

6. **Interact if needed** — if the change involves interactive elements (buttons, forms, modals), use `browser_click`, `browser_fill`, or `browser_hover` to test the interaction, then take another screenshot to verify.

7. **Report findings** — summarize:
   - Screenshot shows the UI looks correct (or what's wrong)
   - Console is clean (or list errors found)
   - Network requests are healthy (or list failures)
