What is obsidian-markdown?

A guide for creating and editing Obsidian Markdown, the note format used by the Obsidian knowledge-management app, including its links, embeds, callouts, and properties.

Use it to create or update Obsidian notes with internal links, embedded files, metadata, tags, callout boxes, and block references.

It helps keep notes valid in Obsidian instead of treating them as ordinary Markdown files.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00071	$0.02314
Opus 5	$0.00036	$0.01157
Sonnet 5	$0.00014	$0.00463
Haiku 4.5	$0.00007	$0.00231

Security

Grade A, and why

obsidian-markdown scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 469 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Obsidian Flavored Markdown

This skill enables AI coding assistants to create and edit valid Obsidian Flavored Markdown including wikilinks, embeds, callouts, properties, and all related syntax.

When to Use

Working with .md files in an Obsidian vault
Creating notes with wikilinks or internal links
Adding embeds for notes, images, audio, or PDFs
Using callouts (info boxes, warnings, tips, etc.)
Managing frontmatter/properties in YAML format
Working with tags and nested tags
Creating block references and block IDs

Basic Formatting

Paragraphs and Line Breaks

Paragraphs are separated by blank lines. Single line breaks within a paragraph are ignored unless you use:

Two spaces at the end of a line
Or use <br> for explicit breaks

Headings

# Heading 1
## Heading 2
### Heading 3
#### Heading 4
##### Heading 5
###### Heading 6

Text Styling

**Bold text**
*Italic text*
***Bold and italic***
~~Strikethrough~~
==Highlighted text==

Internal Links (Wikilinks)

Basic Wikilinks

[[Note Name]]
[[Note Name|Display Text]]
[[Folder/Note Name]]

Heading Links

[[Note Name#Heading]]
[[Note Name#Heading|Display Text]]
[[#Heading in Current Note]]

Block References

[[Note Name#^block-id]]
[[Note Name#^block-id|Display Text]]
[[#^block-id]]

Creating Block IDs

Add a block ID at the end of any paragraph or list item:

This is a paragraph you can reference. ^my-block-id

- List item with ID ^list-block

Embeds

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
