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 | $0.03155 |
| Opus 5 | $0.00036 | $0.01577 |
| Sonnet 5 | $0.00014 | $0.00631 |
| Haiku 4.5 | $0.00007 | $0.00315 |
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 — 1 line 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 — 620 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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:
- CommonMark
- GitHub Flavored Markdown
- LaTeX for math
- Obsidian-specific extensions (wikilinks, callouts, embeds, etc.)
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~~ |
|
| 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: \*, \_, \#, \`, \|, \~
Internal Links (Wikilinks)
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
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.

obsidian-markdown is a skill published in the GitHub repository MarsZ42/OrbitOS (970 stars, last pushed 5mo ago), licensed MIT. It adds 71 tokens to every session and 3,155 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to obsidian-markdown, differing in 1 line, and is treated as a copy.
