Greptile Overview

Greptile Summary

Disabled Next.js image optimization for external branding images and user avatars by adding the unoptimized prop, and improved Helm chart documentation with URI format validation and clearer guidance for branding URL configuration.

Key Changes:

• Added unoptimized prop to custom branding logo in chat header (apps/sim/app/chat/components/header/header.tsx:40)
• Added unoptimized prop to help modal preview images (apps/sim/app/workspace/[workspaceId]/w/components/sidebar/components-new/help-modal/help-modal.tsx:526)
• Simplified avatar image optimization by removing conditional logic and making all avatars unoptimized (apps/sim/app/workspace/[workspaceId]/w/components/sidebar/components-new/workflow-list/components/workflow-item/avatars/avatars.tsx:65)
• Enhanced Helm schema with format: "uri" validation and improved descriptions for NEXT_PUBLIC_BRAND_LOGO_URL, NEXT_PUBLIC_BRAND_FAVICON_URL, and NEXT_PUBLIC_CUSTOM_CSS_URL (helm/sim/values.schema.json:241-251)

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• All changes are straightforward and well-scoped. The addition of unoptimized props addresses Next.js image optimization issues with external URLs (likely following upgrade to Next.js 16). The Helm chart improvements add valuable validation and documentation without breaking changes. No logic errors, security issues, or breaking changes detected.
• No files require special attention
