# file-share

Upload local files to temporary file sharing services to get public download links.

## Important

- Always prefer using the channel's native file sending capability via the `message` tool first - this provides the best user experience. Only use this as a fallback when native file sending is unavailable or fails.

+ Prefer the channel's native attachment delivery when available. A failed send is not permission to upload the file to a third party. Before uploading, obtain explicit user approval for the selected public service and file; do not upload sensitive information. A background task returns its artifact path to the main Agent and does not send channel messages itself.

## Available Services

### tmpfiles.org (Recommended, 1 hour expiry, 100MB)

```bash

curl -s -F "file=@<file_path>" https://tmpfiles.org/api/v1/upload

# Returns: {"status":"success","data":{"url":"http://tmpfiles.org/12345/file.pdf"}}

# Note: Add /dl to URL for direct download: http://tmpfiles.org/dl/12345/file.pdf

```

### uguu.se (48 hours expiry, 128MB)

```bash

curl -s -F "files[]=@<file_path>" https://uguu.se/upload.php

```

## Workflow

- 1. Generate/process file and save to `data/` directory

- 2. Upload using one of the commands above

+ 1. Generate/process the file in the assigned workspace (task outputs stay in that task directory)

+ 2. Confirm explicit user approval of the file and public service, then upload using the selected command

3. Extract the download URL from response

- 4. Send the download link to the user

+ 4. Return the link to the main Agent for channel delivery, or use the channel tool only if this role actually provides it

## Notes

- Verify the file exists before uploading

- For tmpfiles.org, add `/dl` to URL for direct download
