Overview

Created by Steph Ango (Kepano), the `obsidian-markdown` skill gives skills-compatible coding agents a focused reference for editing Obsidian Markdown. It covers wikilinks, block and heading links, embeds, callouts, properties, tags, comments, math, Mermaid diagrams, and footnotes, then asks the agent to verify the result in Obsidian reading view.

Key Features

How to Install Obsidian Markdown

  1. 1Use the repository's marketplace or npx command when your agent supports that installation path.
  2. 2For Codex, copy the repository's skills directory into the configured Codex skills path, commonly ~/.codex/skills.
  3. 3For Claude Code, place the repository contents in a .claude folder at the root of the vault or working directory.
  4. 4For OpenCode, clone the full repository into the OpenCode skills directory so its nested skill folders remain discoverable.
  5. 5Restart or open a fresh agent session, then confirm that obsidian-markdown appears in the available skills list.

How to Use Obsidian Markdown

Ask the agent to create or edit a Markdown file inside a test vault. A useful first prompt is: Use the obsidian-markdown skill to create Project Alpha.md with title and tags properties, a link to [[Project Brief]], a warning callout, and an embedded image. Open the note in Obsidian reading view and verify every element before applying the workflow to important notes.

What the Skill Changes

This is an instruction package, not an Obsidian plugin or a connection to your vault. It teaches an agent the syntax and verification sequence to follow when a request involves Obsidian Markdown. The agent still needs filesystem access supplied by its host, and installing the skill does not grant new permissions or start a background service.

End-to-End Test

Begin in a disposable vault. Ask for one note containing properties, a wikilink, a callout, and an embed. Then inspect both source mode and reading view: confirm frontmatter starts on the first line, the link resolves, the callout renders, and the embedded file exists. Only after this check should the agent edit a real vault.

Example prompt
Use the obsidian-markdown skill to create Project Alpha.md. Add title and tags properties, link to [[Project Brief]], include a warning callout, and embed ![[Architecture.png|600]]. Do not invent linked files; report any missing target.

Compatibility and Safety

  • Agent Skills provide instructions, not enforcement. Review the generated diff before accepting bulk changes.
  • Install from the source repository and retain its reference files; copying only an excerpt can omit property, embed, or callout guidance.
  • A skills-compatible agent may use a different discovery path. Follow the host's documentation instead of assuming one global folder works everywhere.
  • Back up the vault or use version control before asking an agent to rename links or edit many notes.

What does this skill do?

Provides a reusable syntax and workflow reference for agents editing Obsidian-flavored Markdown, including internal links, callouts, embeds, math, and frontmatter properties.

Best for

  • Giving AI agents a consistent Obsidian Markdown syntax reference
  • Preventing agents from writing standard Markdown when Obsidian syntax is required
  • Mastering callout types, math blocks, and internal link aliases

How it works

  • Loaded into agent session when working in Obsidian vaults
  • Instructs agent on exact rules for wikilinks `[[Note#Heading|Alias]]`
  • Defines supported callout types (`[!note]`, `[!warning]`, `[!tip]`, etc.)
  • Specifies transclusion syntax `![[Note]]`
