# Report Shopify Performance

Measure storefront speed, responsiveness, page weight, assets, and scripts.

| Context | What to provide |
| --- | --- |
| Required context | Storefront or already prepared preview URL. |
| Optional context | Exact pages, field data, and compatible prior performance reports. |

**Execution requirements:** Browser and measurement capabilities for the requested metrics. Supports Glue's read-only reviews and other hosts; no repository or integration is required. Unavailable measurements stay unavailable, and local timings remain lab evidence.

Local runs link the complete shared-schema `report.json` with a readable result summary. Glue manages its JSON results.

## How to use

1. Invoke `$report-shopify-performance` to collect supported metrics with their route, viewport, and method.
2. Review normalized Data, evidence-backed performance Issues, and measurement Limitations.
