+name: Zensical Docs Markdown Guidance
+description: Use the Zensical docs MCP resource when editing Markdown documentation in this repository.
+applyTo: '**/*.md'
+---
+
+When editing Markdown files in this repository, use the Zensical docs resource `resource://skills/zensical-docs/document` for relevant documentation authoring guidance.
+
+Prefer Zensical-native documentation conventions when they cover the need cleanly, while preserving expected MkDocs compatibility unless the Zensical guidance intentionally diverges.
