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.

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 9d 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.

Obsidian Flavored Markdown Skill

This skill enables skills-compatible agents to create and edit valid Obsidian Flavored Markdown, including all Obsidian-specific syntax extensions.

Overview

Obsidian uses a combination of Markdown flavors:

Basic Formatting

Paragraphs and Line Breaks

This is a paragraph.

This is another paragraph (blank line between creates separate paragraphs).

For a line break within a paragraph, add two spaces at the end  
or use Shift+Enter.

Headings

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

Text Formatting

Style Syntax Example Output
Bold **text** or __text__ **Bold** Bold
Italic *text* or _text_ *Italic* Italic
Bold + Italic ***text*** ***Both*** Both
Strikethrough ~~text~~ ~~Striked~~ Striked
Highlight ==text== ==Highlighted== ==Highlighted==
Inline code `code` `code` code

Escaping Formatting

Use backslash to escape special characters:

\*This won't be italic\*
\#This won't be a heading
1\. This won't be a list item

Common characters to escape: \*, \_, \#, \`, \|, \~

Basic Links

[[Note Name]]
[[Note Name.md]]
[[Note Name|Display Text]]

Link to Headings

[[Note Name#Heading]]
[[Note Name#Heading|Custom Text]]
[[#Heading in same note]]
[[##Search all headings in vault]]

Link to Blocks

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

Define a block ID by adding ^block-id at the end of a paragraph:

This is a paragraph that can be linked to. ^my-block-id
