Discord Markdown Formatting

Format text for Discord's chat rendering engine. Discord uses a modified subset of Markdown with some unique additions (spoilers, timestamps, subtext, guild navigation).

Output Presentation — CRITICAL

When composing a Discord message for the user, always present the final message inside a fenced code block so the user can copy-paste it directly into Discord with all markdown formatting intact.

Why: Claude's chat interface renders markdown (e.g., **bold** becomes bold). If the user copies rendered text, the markdown syntax is stripped and the message loses its formatting when pasted into Discord. A code block preserves the raw syntax.

How to Present Discord Messages

Always wrap the final copy-paste-ready message in a fenced code block with the markdown language tag:

INLINECODE2

Rules

1. 1. Always use a fenced code block — Triple backticks with markdown language identifier
2. The ENTIRE message goes in ONE block — Everything the user will paste into Discord lives inside a single fenced code block. No part of the Discord message should ever appear outside the block as rendered markdown
3. Explain outside the block — Put any notes, options, or context before or after the code block, never inside it
4. Handle nested code blocks — If the Discord message itself contains code blocks, use four backticks (`````) as the outer fence so the inner triple backticks are preserved. The user copies everything between the outer fence — the inner triple backticks are part of the Discord message: CODEBLOCK2markdown

Here's some code:

CODEBLOCK3

Pretty cool right?
CODEBLOCK4 5. **Multiple messages = multiple blocks** — If providing alternatives or a multi-message sequence, use a separate code block for each with a label above it 6. **Message metadata summary** — Always display a metadata summary table immediately after every Discord message code block (see below) 7. **Templates too** — When presenting templates from the reference files, they should also be in copyable code blocks following these same rules 8. **Never partially render** — Do NOT put headers, bold text, code snippets, or any other Discord-formatted content outside the code block. If it's part of the Discord message, it goes inside the block. The user should never have to assemble a message from rendered markdown and code blocks ### Message Metadata Summary After **every** Discord message code block, include a summary table with the following stats: | Stat | Description | How to Count | | -------------------- | ------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------- | | **Characters** | Total character count of the message | Count all characters inside the code block. Show as X / 2,000 for chat messages or X / 4,096 for embed descriptions | | **Sections** | Number of header-delimited sections | Count all #, ##, ### headers. If no headers, show 0 | | **User Mentions** | Users mentioned via <@USERID> or <@!USERID> | Count unique <@...> patterns (not role mentions) | | **Role Mentions** | Roles mentioned via <@&ROLEID> | Count unique <@&...> patterns. Include @everyone and @here | | **Channel Mentions** | Channels linked via <#CHANNELID> or | Count unique <#...> and patterns | | **URLs** | Links in the message | Count raw URLs and masked links text | | **Code Blocks** | Code blocks with language info | If the message contains fenced code blocks, list languages used (e.g., javascript, bash). Show — if none | Format the summary as a compact table directly below the code block: CODEBLOCK5 **Notes:** - For role mentions, parenthetically note if @everyone or @here is included since those ping the entire server - For code blocks, list each language, e.g. javascript, bash — or (no lang) if the block has no language identifier - If characters exceed 80% of the limit, add a ⚠️ warning - If characters exceed the limit, add a 🚫 and suggest splitting the message ### Example Interaction **User:** "Write me a Discord announcement about a new SDK release that includes code examples" **Claude's response should look like:** Here's your SDK announcement:

# 🚀 Volvox SDK v2.0 — Breaking Changes

Hey @everyone — we just shipped **v2.0** of the SDK and there are a few things you need to know before upgrading.

## What Changed

The `createJar` method now accepts an options object instead of positional arguments:

**Before:**

ts
const jar = createJar("Lunch Spots", ["Chipotle", "Sweetgreen"], true);

**After:**

ts
const jar = createJar({
name: "Lunch Spots",
options: ["Chipotle", "Sweetgreen"],
allowDuplicates: true,
});

## New: Shake Events

ts
jar.on("shake", (result) => {
console.log(🎉 Selected: ${result.option});
});

| Stat | Value | | ---------------- | -------------------- | | Characters | 659 / 2,000 | | Sections | 3 | | User Mentions | 1 | | Role Mentions | 1 (@everyone) | | Channel Mentions | 2 | | URLs | 0 | | Code Blocks | 3 — ts, ts, ts | **Key:** Notice the outer fence uses four backticks (````) because the Discord message contains inner triple-backtick code blocks. The user copies everything between the outer fence — inner backticks are part of the message. --- ## Quick Reference | Style | Syntax | Renders As | | --------------------- | -------------------- | -------------------- | | Bold | text | **text** | | Italic | text or text | _text_ | | Underline | text | underlined text | | Strikethrough | ~~text~~ | ~~text~~ | | Spoiler | \|\|text\|\| | hidden until clicked | | Inline code | code | monospaced | | Bold italic | text | **_text_** | | Underline italic | text | underlined italic | | Underline bold | text | underlined bold | | Underline bold italic | text | all three | | Strikethrough bold | ~~text~~ | struck bold | ## Text Formatting ### Emphasis CODEBLOCK10 ### Combining Styles Nest formatting markers from outside in. Discord resolves them in this order: underline → bold → italic → strikethrough. CODEBLOCK11 ### Escaping Prefix any markdown character with \ to display it literally: CODEBLOCK12 ## Headers Headers require # at the **start of a line** followed by a space. Only three levels are supported. CODEBLOCK13 **Important:** Headers do not work inline. The # must be the first character on the line. ## Subtext Small, muted gray text below content. Useful for footnotes, disclaimers, or attribution. CODEBLOCK14 ## Block Quotes ### Single-line CODEBLOCK15 ### Multi-line Everything after >>> (including subsequent lines) becomes quoted: CODEBLOCK16 ## Lists ### Unordered Use - or * with a space. Indent with spaces for nesting: CODEBLOCK17 ### Ordered CODEBLOCK18 **Auto-numbering trick:** Discord auto-increments if you repeat 1.: CODEBLOCK19 ## Code Blocks ### Inline Code CODEBLOCK20 ### Multi-line Code Block Wrap code with triple backticks on their own lines:

function hello() {
return "world";
}

### Syntax Highlighting Add a language identifier after the opening backticks:

javascript
function hello() {
return "world";
}

See [references/syntax-highlighting.md](references/syntax-highlighting.md) for the full list of supported languages. **Commonly used languages:** javascript, typescript, python, csharp, json, bash, css, html, sql, yaml, diff, markdown ## Links ### Masked Links CODEBLOCK25 **Note:** Masked links work in embeds and some contexts, but regular chat may show a preview. Discord may suppress masked links from bots in certain conditions. ### Auto-linking Discord auto-links any valid URL pasted directly: CODEBLOCK26 ### Suppressing Link Previews Wrap a URL in angle brackets to prevent Discord from generating a preview embed: CODEBLOCK27 ## Timestamps Dynamic timestamps that display in each user's local timezone. **Format:** TIMESTAMP:FORMATFLAG> | Flag | Output Style | Example | | ---- | ------------------------- | ---------------------------------- | | t | Short time | 4:20 PM | | T | Long time | 4:20:30 PM | | d | Short date | 02/08/2026 | | D | Long date | February 8, 2026 | | f | Short date/time (default) | February 8, 2026 4:20 PM | | F | Long date/time | Sunday, February 8, 2026 4:20 PM | | R | Relative | 2 hours ago | **Example:** CODEBLOCK28 **Tip:** Use Math.floor(Date.now() / 1000) or date +%s to get the current Unix timestamp. ## Mentions & References CODEBLOCK29 ## Emoji CODEBLOCK30 ## Discord-Specific Gotchas 1. **No nested block quotes** — Discord does not support >> for nested quotes 2. **Headers need line start** — # must be the first character on the line (not inline) 3. **Underline is NOT standard Markdown** — text underlines in Discord but bolds in standard Markdown 4. **Spoilers are Discord-only** — ||text|| has no equivalent in standard Markdown 5. **Lists need a blank line** — Start lists after a blank line or they may not render 6. **Embed markdown differs** — Some formatting behaves differently in embeds vs chat messages 7. **2000 character limit** — Standard messages max at 2,000 characters; nitro users get 4,000 8. **Embed description limit** — Embed descriptions max at 4,096 characters 9. **Code block language names are case-insensitive** — JS, js, and JavaScript` all work
