Congratulations on your new Raycast extension! 🚀

We're currently experiencing a high volume of incoming requests. As a result, the initial review may take up to 10-15 business days.

Once the PR is approved and merged, the extension will be available on our Store.

Greptile Summary

This PR adds a new Similarweb extension with two commands: Show Website Data (fetches analytics for a typed domain or the active browser tab) and History (browses locally stored snapshots). The implementation is clean — domain parsing, LocalStorage persistence, Markdown rendering, and cancellation guards are all well-handled. The one remaining style note is that formatTimestamp calls toLocaleString() without a locale argument, producing system-locale-dependent output; the rest of the previously raised issues (unused @raycast/utils dependency, missing categories, action title mismatch, and save-failure toast) appear to have been resolved in this revision.

Confidence Score: 5/5

Safe to merge; the only remaining finding is a P2 locale style issue in timestamp formatting.

All P1 issues from prior review rounds have been addressed. The single new finding is a P2 style note (toLocaleString() without locale), which does not affect correctness or safety.

No files require special attention beyond the one-line formatTimestamp fix in src/lib/format.ts.

Comment:
**`toLocaleString()` uses the system locale**

`new Date(value).toLocaleString()` formats the timestamp using the OS locale, so users with non-English system settings will see dates in their local language. Raycast only supports US English; passing `"en-US"` keeps output consistent across all machines.

```suggestion
function formatTimestamp(value: string): string {
  return new Date(value).toLocaleString("en-US");
}
```
