Markdown OKF-Schema Studio is a VS Code extension providing a visual, block-level WYSIWYG editor for CommonMark, GFM, Sphinx MyST, OKF, and OKF-Schema documents. It distinguishes itself through schema-aware frontmatter editing, inline Mermaid/PlantUML/Vega-Lite rendering without external runtimes, git-diff block highlighting, and collaborative comment threads stored in sidecar JSON files. The focus on preserving raw Markdown fidelity and supporting agent-authored plans makes it a thoughtfully engineered tool for modern documentation workflows.

Target audience: developers, technical writers, and docs engineers working with Markdown in VS Code
