Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 5.1 | $0.00071 | $0.01391 |
| Opus 5 | $0.00036 | $0.00696 |
| Sonnet 5 | $0.00014 | $0.00278 |
| Haiku 4.5 | $0.00007 | $0.00139 |
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.
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 — 197 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Obsidian Flavored Markdown Skill
Create and edit valid Obsidian Flavored Markdown. Obsidian extends CommonMark and GFM with wikilinks, embeds, callouts, properties, comments, and other syntax. This skill covers only Obsidian-specific extensions -- standard Markdown (headings, bold, italic, lists, quotes, code blocks, tables) is assumed knowledge.
Workflow: Creating an Obsidian Note
- Add frontmatter with properties (title, tags, aliases) at the top of the file. See PROPERTIES.md for all property types.
- Write content using standard Markdown for structure, plus Obsidian-specific syntax below.
- Link related notes using wikilinks (
[[Note]]) for internal vault connections, or standard Markdown links for external URLs. - Embed content from other notes, images, or PDFs using the
![[embed]]syntax. See EMBEDS.md for all embed types. - Add callouts for highlighted information using
> [!type]syntax. See CALLOUTS.md for all callout types. - Verify the note renders correctly in Obsidian's reading view.
When choosing between wikilinks and Markdown links: use
[[wikilinks]]for notes within the vault (Obsidian tracks renames automatically) and[text](url)for external URLs only.
Internal Links (Wikilinks)
[[Note Name]] Link to note
[[Note Name|Display Text]] Custom display text
[[Note Name#Heading]] Link to heading
[[Note Name#^block-id]] Link to block
[[#Heading in same note]] Same-note heading link
Define a block ID by appending ^block-id to any paragraph:
This paragraph can be linked to. ^my-block-id
For lists and quotes, place the block ID on a separate line after the block:
> A quote block
^quote-id
Embeds
Prefix any wikilink with ! to embed its content inline:
![[Note Name]] Embed full note
![[Note Name#Heading]] Embed section
![[image.png]] Embed image
![[image.png|300]] Embed image with width
![[document.pdf#page=3]] Embed PDF page
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
