| The Sentry Cloudflare Vite plugin (`sentryCloudflareVitePlugin`) instruments your Worker at build time. It can: | ||
|
|
||
| 1. **Instrument bundled dependencies** — injects [`diagnostics_channel.tracingChannel`](https://nodejs.org/api/diagnostics_channel.html#class-tracingchannel) calls into supported packages (such as database clients like `mysql`) so the SDK can trace them without monkey-patching, which the Cloudflare Workers runtime (`workerd`) doesn't support. This gives you more traces out of the box. |

l: For me this explains internal details too much. I wouldn't even talk about injecting channels and whatnot. Just that it automatically instruments your bundled dependencies at build time?

Agreed, dropped the internals — now just says it automatically instruments supported packages in your bundle at build time. e6956b0

| 2. **Auto-instrument your Worker entry** — optionally wraps your default export with `Sentry.withSentry()` and Durable Objects with `instrumentDurableObjectWithSentry()` at build time, so you don't need to modify your code. | ||

| **We recommend building your Cloudflare Worker with Vite and this plugin.** It's the most complete way to get tracing for bundled dependencies in the Workers runtime, where runtime monkey-patching isn't available. If you already deploy with `wrangler` directly, see [Migrating From Wrangler](#migrating-from-wrangler). |

Applied, thanks! (minus the monkey-patching clause per your other comment) e6956b0

l: I wouldn't talk about runtime monkey-patching. Again, too much internal detail. I'd just drop the "when runtime monkey-patchign isn't available" as a whole.
Drop internal implementation details (diagnostics_channel injection, monkey-patching) from the feature overview per review feedback. The intro now just states the plugin automatically instruments bundled dependencies at build time. Co-Authored-By: Claude <noreply@anthropic.com>

With that we recommend to use Vite instead of plain
wrangler. This also documents the new 2 experimental flags withuseDiagnosticsChannelInjectionandautoInstrument. In the quick start we even adduseDiagnosticsChannelInjectionin order to get the most out of the instrumentationsIS YOUR CHANGE URGENT?

LEGAL BOILERPLATE
Look, I get it. The entity doing business as "Sentry" was incorporated in the State of Delaware in 2015 as Functional Software, Inc. and is gonna need some rights from me in order to utilize my contributions in this here PR. So here's the deal: I retain all rights, title and interest in and to my contributions, and by keeping this boilerplate intact I confirm that Sentry can use, modify, copy, and redistribute my contributions, under Sentry's choice of terms.
