I wrote my own version too, a while back, because it seemed like it would be useful (and indeed it has been) - a golang tool to list/search/run named blocks from markdown, joining multiple blocks together if instructed to do so:
We've expanded significantly onto the idea of a toy script/utility to bring multi-modality (editor, notebook, terminal, browser) with shared sessions to what's at the core, a universal task runner (see architecture link below).
