Obsidian Markdown Standard

Purpose

Define a shared specification for all markdown documents generated by SynapSync skills, ensuring every .md output is Obsidian-native — with rich YAML frontmatter, wiki-links, bidirectional references, living document patterns, trackable IDs, and metric tables. When multiple skills produce documents for the same project, the result is an interconnected knowledge graph in Obsidian, not a collection of isolated files.

This skill is a specification — it is not invoked directly by users. Other skills reference it and embed the relevant compact profile into their output instructions.

When to Use This Skill

• Skill authors: When creating or updating a SynapSync skill that writes .md files to {output_base}
• Reference: When validating that generated documents follow the Obsidian-native standard
• Not for direct invocation: Users do not call this skill — it is consumed by other skills

Specification
