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 7d 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.

Origin

This is a copy

100% identical to obsidian-markdown — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 232 lines — stays where its author put it; the contents beside it link to each section on GitHub.

obsidian-markdown: Obsidian Flavored Markdown

Reference this skill when writing any wiki page. Obsidian extends standard Markdown with wikilinks, embeds, callouts, and properties. Getting syntax wrong causes broken links, invisible callouts, or malformed frontmatter.

Cross-reference: If the kepano/obsidian-skills plugin is installed, prefer its canonical obsidian-markdown skill for authoritative Obsidian syntax reference. Otherwise, use the reference below. See also github.com/kepano/obsidian-skills.


Internal links use double brackets. The filename without extension.

Syntax What it does
[[Note Name]] Basic link
[[Note Name|Display Text]] Aliased link (shows "Display Text")
[[Note Name#Heading]] Link to a specific heading
[[Note Name#^block-id]] Link to a specific block

Rules:

  • Case-sensitive on some systems. Match the exact filename.
  • No path needed: Obsidian resolves by filename uniqueness.
  • If two files have the same name, use [[Folder/Note Name]] to disambiguate.

Embeds

Embeds use ! before the wikilink. They display the content inline.

Syntax What it does
![[Note Name]] Embed a full note
![[Note Name#Heading]] Embed a section
![[image.png]] Embed an image
![[image.png|300]] Embed image with width 300px
![[document.pdf]] Embed a PDF (Obsidian renders natively)
![[audio.mp3]] Embed audio

Callouts

Callouts are blockquotes with a type keyword. They render as styled alert boxes.

> [!note]
> Default informational callout.

> [!note] Custom Title
> Callout with a custom title.

> [!note]- Collapsible (closed by default)
> Click to expand.

> [!note]+ Collapsible (open by default)
> Click to collapse.

All callout types

Type Aliases Use for
note : General notes
abstract summary, tldr Summaries
info : Information
todo : Action items
tip hint, important Tips and highlights
success check, done Positive outcomes
question help, faq Open questions
warning caution, attention Warnings
failure fail, missing Errors or failures
danger error Critical issues
bug : Known bugs
example : Examples
quote cite Quotations
contradiction : Conflicting information (wiki convention)

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.
