Show HN: Margarita - Programming Agents with Markdown

Margarita is a new programming language (creator's "build it from scratch" project) that lets developers write AI agent workflows using Markdown — the familiar plain-text formatting syntax used in apps like Notion, GitHub READMEs, and chat platforms. Its core pitch: Markdown is already used to describe step-by-step AI workflows, but those files become brittle and repetitive at scale. Margarita adds logical operators (if/else, loops, variables) directly into Markdown, so you get deterministic control where you want it and fall back to LLM-powered "dynamic code" where flexibility helps. It also treats prompts like React components — composable and reusable, avoiding copy-paste across hundreds of files. The author built it primarily as a learning exercise and to address frustrations with existing "skills libraries" for AI workflows, but notes lukewarm reception.
