BlockFlow

Build new blocks for BlockFlow, the visual pipeline editor for AI video and image generation. Use this skill whenever the user wants to create a new block, extend BlockFlow's functionality, add a pipeline step, build a custom node, or asks about the block architecture. Also trigger when the user mentions "custom_blocks", "frontend.block.tsx", "backend.block.py", block inputs/outputs, port types, or block registration. Even casual requests like "add a block that does X" or "I want a new pipeline step for Y" should use this skill.
