1. File-only upload dropped 🐞 Bug ≡ Correctness
In submit(), if the user submits only a file (no text) and the file is >10MB or processing throws, the code only logs and continues, leaving messageParts empty; this makes content an empty string and the if (content) guard skips appending the user message. The pipeline then runs taskManager/researcher using only historical messages, so the response ignores the user’s upload while still consuming tokens.
Agent Prompt
## Issue description
`submit()` allows file-only requests, but when the file is rejected (size > 10MB) or throws during processing, the request continues without creating a user message. This results in the system running `taskManager()`/`researcher()` against stale `messages`, producing an unrelated response and silently ignoring the user’s upload.
## Issue Context
- The code returns early only when *both* `userInput` and `file` are missing.
- If the file is too large or processing fails, no message part is added and `content` becomes `''`.
- Because message append is guarded by `if (content)`, empty string prevents the user message from being appended.
## Fix Focus Areas
- app/actions.tsx[327-335]
- app/actions.tsx[385-475]
- app/actions.tsx[481-529]
## What to change
- When `file.size > MAX_FILE_SIZE`, stop the pipeline (early return) and surface a user-visible error (e.g., append an assistant error message to `uiStream` and `aiState.done(...)`, and set `isGenerating.done(false)` / `uiStream.done()`).
- In the `catch` for file processing, similarly fail fast with a user-visible error.
- Additionally, guard against `messageParts.length === 0` before building/using `content` (so file-only requests can’t fall through into `processEvents()` with no new user message).

Inline comments:
In `@app/actions.tsx`:
- Around line 389-428: The file-processing block that builds messageParts (the
branch handling file, MAX_FILE_SIZE, image/text conversion, and the catch)
currently only logs errors and can leave messageParts unchanged; update this
logic to fail fast by detecting when no usable part was produced and then either
return/throw immediately from the enclosing action or append a user-facing
TextPart error before continuing so processEvents() never runs on stale history;
specifically, after the image/text handling and inside the
catch/oversize/unsupported-MIME branches, set a boolean flag (e.g., fileHandled)
or push a TextPart like {type: 'text', text: 'Upload failed: <brief reason>'}
and short-circuit the function (or return that error to the caller) so
processEvents() is not invoked with no new message part. Ensure changes touch
the same symbols: the file handling block that uses file.arrayBuffer(),
messageParts, ImagePart/TextPart, and the later processEvents() caller.
- Around line 401-413: The logs currently leak base64 image bytes via
dataUrl.substring(...) and imagePart.image.substring(...) — remove those
substring logs and replace them with non-sensitive metadata: log image MIME type
(file.type), byte/character length (dataUrl.length), and a short content
fingerprint (e.g., SHA-256 hex or truncated hash computed from dataUrl) instead;
update the console messages around dataUrl and imagePart (the places where
dataUrl, imagePart, and ImagePart are constructed) to output only mimeType,
totalLength, and the computed hash/fingerprint.
- Around line 405-414: The code currently pushes raw base64 data URLs into
aiState.messages via the imagePart object (type: 'image', image: dataUrl) which
later flows through onSetAIState into saveChat(), causing large binary blobs to
be persisted; update the logic that constructs and pushes imagePart (and the
similar block referenced at the other location) to avoid storing the full data
URL—replace the image field with either a sentinel string like 'IMAGE_PROCESSED'
or an asset reference/id after uploading the file to your asset store, and only
keep the real base64/data URL transiently for immediate use (e.g.,
preview/upload) before substituting the persistent imagePart prior to calling
onSetAIState/saveChat.
- Around line 348-368: The historical message filter currently preserves image
parts with ImagePart.image === 'IMAGE_PROCESSED'; update the filter logic (the
map over messages that builds filteredContent) to exclude or replace the
'IMAGE_PROCESSED' sentinel when constructing messages that will be sent to the
model (CoreMessage[]), not just when persisting/displaying history. Ensure the
UI/persistence code can still store the sentinel but the code path that prepares
messages for the model (the place where messages are forwarded into
nonexperimental_streamText in researcher logic) replaces 'IMAGE_PROCESSED' with
a real image payload or removes the image part so the model never receives the
sentinel; reference the ImagePart.image checks and the
nonexperimental_streamText/CoreMessage[] construction to locate the changes.

🧩 Analysis chain
🌐 Web query:
For AI SDK version 4.3.19, what values are valid for ImagePart.imageinsideCoreMessage['content']? Is an arbitrary sentinel string like IMAGE_PROCESSED supported in provider requests, or must it be an actual data URL/URL/binary payload?
💡 Result:
For AI SDK version 4.3.19, the ImagePart.image property is designed to hold actual image data or a reference to it, and it does not support arbitrary sentinel strings like IMAGE_PROCESSED [1][2]. The valid types for ImagePart.image are restricted to the following [1][3][4]: - Data payloads: base64-encoded strings, Uint8Array, ArrayBuffer, or Buffer [1][3][4]. - URLs: a URL object or string pointing to an image (e.g., http(s) URLs or base64 data URLs) [1][3][4]. Providing an arbitrary string that does not conform to these formats (i.e., is not a valid data representation or a valid URL) will generally cause the SDK or the underlying model provider to fail, as they expect valid image content to process [3][4]. Note that in recent versions of the AI SDK, ImagePart has been deprecated in favor of FilePart (using { type: 'file', mediaType: 'image', data: ... }) [5][6]. If you need to include metadata or indicate that an image has already been processed, this should be handled through other fields, such as providerOptions, or by managing the file state outside of the ImagePart content array [7][6].

Stop preserving IMAGE_PROCESSED as an ImagePart.image sent to the SDK
app/actions.tsx’s historical message filter keeps { type: 'image', image: 'IMAGE_PROCESSED' }, and lib/agents/researcher.tsx forwards messages unchanged into nonexperimental_streamText (and enables the “has image” path whenever any type: 'image' part exists). ImagePart.image must be real image data/URL (or binary payload), not an arbitrary sentinel—strip/replace this placeholder when building the CoreMessage[] passed to the model, while allowing the sentinel only for persisted/UI history.

Fail fast when attachment processing yields no usable part.
Oversize files, unsupported MIME types, and arrayBuffer() failures only log and then fall through. If the request is file-only, Line 327 does not short-circuit because file exists, but no new user message is appended at Lines 458-475, so processEvents() runs against stale history instead of returning a user-facing error for the bad upload.

the same symbols: the file handling block that uses file.arrayBuffer(),
messageParts, ImagePart/TextPart, and the later processEvents() caller.

Don’t log raw base64 image bytes.
The dataUrl.substring(0, 50) and imagePart.image.substring(0, 50) logs still emit user-uploaded content into server logs. These attachments can contain sensitive data, and logs usually outlive request bodies. Log MIME type, byte length, or a hash instead.

console.log('Image processed:', {
- dataUrlPrefix: dataUrl.substring(0, 50),
- totalLength: dataUrl.length
+ mimeType: file.type,
+ payloadBytes: buffer.byteLength,
+ totalLength: dataUrl.length
})
const imagePart: ImagePart = {
type: 'image',
image: dataUrl,
mimeType: file.type
}
console.log('Pushing image part (debug shape):', {

those substring logs and replace them with non-sensitive metadata: log image

where dataUrl, imagePart, and ImagePart are constructed) to output only
mimeType, totalLength, and the computed hash/fingerprint.

Don’t persist raw data URLs in chat history.
When an image is attached, the full base64 data URL is pushed into aiState.messages here. onSetAIState later forwards state.messages straight to saveChat() at Lines 707-735, so each upload is retained in chat storage. A 10MB image becomes ~13MB once base64-encoded, and it also stores the raw user attachment indefinitely. Replace stored images with IMAGE_PROCESSED or an asset reference before persistence.

In `@app/actions.tsx` around lines 405 - 414, The code currently pushes raw base64
data URLs into aiState.messages via the imagePart object (type: 'image', image:
dataUrl) which later flows through onSetAIState into saveChat(), causing large
binary blobs to be persisted; update the logic that constructs and pushes
imagePart (and the similar block referenced at the other location) to avoid
storing the full data URL—replace the image field with either a sentinel string
like 'IMAGE_PROCESSED' or an asset reference/id after uploading the file to your
asset store, and only keep the real base64/data URL transiently for immediate
use (e.g., preview/upload) before substituting the persistent imagePart prior to
calling onSetAIState/saveChat.
