SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Generate and manage images for posts, including diagrams via excalidraw-skill and optional photo-style hero images with DALL-E. It also handles platform-specific resizing with ImageMagick and updates the content manifest with asset references.

Core Features & Use Cases

Generate diagrams and illustrations using excalidraw-skill for architecture diagrams, flowcharts, and concept maps.
Create hero images with DALL-E when an API key is available, or fallback to diagrams for visuals.
Resize images to required platform sizes using ImageMagick, ensuring consistent presentation across platforms.
Update the manifest with generated assets and platform-specific references for each post.
Validate dependencies and plan images before generation to ensure smooth workflows.

Quick Start

Run the image workflow for your latest post to add diagrams and hero images.

FAQPage Schema

How do I automate post image creation and resize diagrams for multiple platforms?▼

Automate post image creation by generating diagrams and hero visuals, then resizing them to platform-specific sizes using ImageMagick. This workflow ensures consistent presentation across multiple platforms while updating the content manifest with the generated asset references.

Can I generate DALL-E hero images for blog posts when an API key is available?▼

Yes, you can generate DALL-E hero images for blog posts when an API key is configured. If the DALL-E API key is unavailable, the workflow falls back to using excalidraw diagrams as the primary visual assets.

Does excalidraw work with ImageMagick for resizing architecture diagrams?▼

Excalidraw works with ImageMagick by first generating architecture diagrams and flowcharts, then using ImageMagick to resize those images to required platform sizes, ensuring consistent visual presentation across different platforms.

What is the best way to manage content manifest updates for generated post assets?▼

Manage content manifest updates by automatically updating the manifest with generated assets and platform-specific variant references for each post. This occurs during the image workflow, linking your diagrams and hero images directly to the content.

Why does image generation fail if dependencies are not validated beforehand?▼

Image generation fails because the workflow validates dependencies on ImageMagick and excalidraw-skill before processing. Validating dependencies and planning images before generation ensures smooth workflows and prevents errors during asset creation.
