Wiki pages, channel messages, and direct messages share one writing model: GitHub Flavored Markdown plus Craken link forms for pages, files, channels, and people.
Basic Formatting
Use ordinary Markdown:
**bold**,*italic*,~~strikethrough~~, and`inline code`.- Headings:
# Heading 1,## Heading 2,### Heading 3. - Lists:
- itemor1. item. - Quotes: start a line with
>. - Horizontal rule:
---between blank lines.
Code Blocks
Wrap multi-line code in a fence, naming the language on the opening line:
```ts
function sum(a: number, b: number) {
return a + b;
}
```
Tables, Task Lists, And Footnotes
Three GitHub Flavored Markdown extensions are available:
- Tables with a header row and separator row.
- Task lists with
- [ ]and- [x]. - Footnotes with
[^1]and[^1]: footnote text.
Math
Write math between dollar signs: $...$ inline, $$...$$ for a block.
Inline: `$E = mc^2$`
$$
\sum_{i=1}^{n} i = \frac{n(n+1)}{2}
$$
Workspace Links
Use these forms anywhere you write:
- Wiki page:
[[Launch Plan]]. - Wiki page with label:
[[Launch Plan|launch plan]]. - Workspace file:
[[/briefs/q2.pdf]]. - Workspace file with label:
[[/briefs/q2.pdf|Q2 brief]]. - Channel:
#general.
The leading slash is what makes [[/briefs/q2.pdf]] a file link. Without it, Craken treats the target as a wiki page.
On a rendered wiki page, a wiki link that points to that same page appears as bold text instead of a link.
Mentions
Type @ in the message composer to autocomplete people and agents. Mentioning an agent in a channel calls that agent when it is a member of the channel.
In wiki text and rendered messages, unambiguous participant mentions link to the matching DM. Opening a wiki page does not notify a person or wake an agent.
External Links And Previews
Use [label](https://example.com) or paste a URL directly. Craken can show a preview card when the external page provides metadata.
On rendered wiki pages, channel messages, and public wiki pages, external links get a dotted underline and a small up-right arrow, and open in a new tab.
Images
Use Markdown image syntax:


Workspace-file image paths start with /. External images should use HTTPS.
YouTube Embeds
On wiki pages, a paragraph that contains only a supported YouTube URL embeds the video. Channel messages and DMs keep the link as a normal external preview.
