 ### Options
 
-- `prefix`: string path prefix for uploaded keys and URLs (e.g. `remote-assets` -> `remote-assets/assets/foo.wasm`).
-- `include`: array of regex or predicate functions to decide which assets to rewrite/upload.
-- `includeBy`: optional `(filename, ctx) => boolean` for finer control (ctx has `hostId`, `hostType`).
+- `provider` (required): object implementing `UploadProvider` (see below).
+- `prefix`: string path prefix for uploaded keys and URLs (default: `remote-assets`; e.g. `remote-assets/assets/foo.wasm`).
+- `include`: array of regex or predicate functions to decide which assets to rewrite/upload (empty array means nothing is rewritten).
+- `includeBy`: optional `(filename, ctx) => boolean` for finer control (`ctx` has `hostId`, `hostType`).
+- `contentTypeBy`: optional `(filename) => string | Promise<string | undefined> | undefined` resolver passed to `provider.upload`.
 - `manifest`: when true, emits `remote-assets.manifest.json` describing fileName/key/url/hostId/hostType/size.
-- `contentType`: optional `(filename) => string | undefined` resolver passed to the provider upload.
-- `logger`: optional logger ({ info, warn, error }) for custom logging sinks.
-- `provider`: any object implementing `{ getPublicUrl(key): string; upload(localPath, key, contentType?): Promise<void> }`.
+- `delete`: when true (default), delete uploaded local assets from disk after upload.
+- `clean`: when true (default), call `provider.cleanPrefix(prefix)` before uploading; skipped if no prefix or provider lacks `cleanPrefix`.
+- `skipNotModified`: when true (default), skip uploads if `provider.shouldSkipUpload` returns true.
+- `dryRun`: when true, rewrite URLs/emit manifest without cleaning or uploading.

 ### createS3Provider

 ## How it works
 
 1. `renderBuiltUrl` returns the remote URL for matching assets while remembering the key/hostId/hostType.
-2. In `generateBundle`, local artifacts are uploaded via the provider.
-3. Optional manifest is emitted for traceability/debugging.
+2. `generateBundle` records assets to upload, emits the optional manifest, and leaves the local files in `dist/`.
+3. `closeBundle` optionally cleans the prefix, skips unmodified uploads when supported, uploads assets, and deletes local copies (unless `delete` is false).
