Obsidian Markdown

What it does

When your agent uses it

• Working with .md files in Obsidian
• The user mentions wikilinks

Example prompts

• “/obsidian-markdown”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Add frontmatter with properties (title, tags, aliases) at the top of the file. See PROPERTIES.md for all property types.
2. 2Write content using standard Markdown for structure, plus Obsidian-specific syntax below.
3. 3Link related notes using wikilinks ([[Note]]) for internal vault connections, or standard Markdown links for external URLs.
4. 4Embed content from other notes, images, or PDFs using the ![[embed]] syntax. See EMBEDS.md for all embed types.
5. 5Add callouts for highlighted information using > [!type] syntax. See CALLOUTS.md for all callout types.
6. 6Verify the note renders correctly in Obsidian's reading view.

What it can do on your machine

Read from SKILL.md and the folder at commit db94dd6. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown and yaml).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Links to these hosts (documentation or services it may open):

  • help.obsidian.md

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Obsidian Markdown loads about 1.4k tokens when it runs, and up to ~2.2k if it reads all its reference files. Until then it costs about 106 tokens; SKILL.md has 376 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~106

When it runs · the whole SKILL.md, loaded when a task matches

~1.4k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~2.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Create and edit Obsidian Flavored Markdown with wikilinks, embeds, callouts, properties, and other Obsidian-specific syntax. Use when working with .md files in Obsidian, or when the user mentions wikilinks, callouts, frontmatter, tags, embeds, or Obsidian notes. Also applies to Dulus memory files at ~/.dulus/memory/ — open that folder as an Obsidian vault for instant graph view of your agent's memory.
