Greptile Summary
This PR implements restrictions for copilot file uploads to only accept image files. The changes span multiple layers of the application architecture:
Core Changes:
- Adds a new
isImageFileTypeutility function infile-utils.tsthat validates MIME types against supported image formats (JPEG, JPG, PNG, GIF, WebP, SVG) - Modifies the presigned upload route to enforce image-only validation for copilot uploads, throwing validation errors for unsupported file types
- Updates the copilot user input component to filter out non-image files during processing and restricts the HTML file input to
accept='image/*' - Changes the default SIM agent API URL from staging to production (
https://staging.agent.sim.aitohttps://agent.sim.ai)
The implementation follows a layered validation approach: frontend filtering prevents non-image selection, client-side processing skips non-image files with warning logs, and backend validation provides the final security barrier. This ensures that copilot functionality is restricted to visual content processing, which aligns with typical AI copilot use cases that focus on image analysis rather than document processing.
The existing document upload functionality for other parts of the application (like knowledge bases) remains unchanged, as evidenced by the existing isSupportedFileType function and comprehensive MIME type mappings that continue to support various document formats.
PR Description Notes:
- The PR description is incomplete with placeholder text and no actual issue number referenced
- Testing section and checkboxes are left blank
Confidence score: 3/5
- This PR requires careful review due to the production API URL change and incomplete validation coverage
- Score reflects concerns about the API environment switch and potential UX inconsistencies in file handling
- Pay close attention to the API URL change in constants.ts and the user input validation logic

logic: image/jpg is not a standard MIME type - image/jpeg covers both .jpg and .jpeg extensions
