Visual regression testing — pixel-by-pixel screenshot comparison against a baseline, free and local. TRIGGER when: user mentions "pixel-perfect", "visual regression", "screenshot diff", "snapshot mismatch", "toHaveScreenshot", "UI looks broken after changes", "compare before/after screenshots", "visual QA", "catch visual bugs", "design implementation check", "tests failing with screenshot", or wants to verify that code changes didn't break the UI visually.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Pixel Perfect
**Note:** Use pixel-perfect by default (free); use visual-regression-tester when you need hosted Chromatic integration.
## Step 1: Check State
Run all three commands, then use the table to choose your workflow.
```bash
ls playwright.config.ts 2>/dev/null && echo "CONFIG_EXISTS" || echo "CONFIG_MISSING"
find snapshots/ -name "*.png" 2>/dev/null | head -1 | grep -q . && echo "BASELINES_EXIST" || echo "BASELINES_MISSING"
curl -s -o /dev/null -w "%{http_code}" --max-time 5 http://<app-host>:<port> 2>/dev/null | grep -q "^2" && echo "SERVER_OK" || echo "NO_SERVER"
```
> If your dev server runs on a port other than 3000, adjust the URL in the curl command above.
| Config | Baselines | Server | → Do this |
|--------|-----------|--------|-----------|
| CONFIG_MISSING | any | any | **→ Workflow A** (Full Setup) |
| CONFIG_EXISTS | BASELINES_MISSING | SERVER_OK | **→ Workflow B** (Capture Baseline) |
| CONFIG_EXISTS | BASELINES_EXIST | SERVER_OK | Run `npx playwright test`. If all tests pass ✓, done. If tests fail → see **Step 2**. |
| CONFIG_EXISTS | BASELINES_EXIST | NO_SERVER | STOP. Tell the user: "Dev server is not running. Start it first, then re-check." |

How to install
mdr add ninjasln-labs/agent-skills/pixel-perfect@sha256:a6dd6a6a428217cfThe line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
