Slack Message Formatting

Slack uses mrkdwn format, NOT standard Markdown.

Text Formatting

Style	Slack mrkdwn	Standard Markdown (WRONG)
Bold	`text`	~~`text`~~
Italic	`_text_`	~~`text`~~
`Code`	`text`	`text` ✓
~~Strike~~	`~text~`	`~text~` ✓

Headers

Slack does NOT support markdown headers.

❌ Wrong: ## Header
✅ Correct: Use *Bold Text* with line breaks

Links

Format: <url|link text>

Lists

Bullet points: • item or - item

Code Blocks

Use triple backticks (same as standard markdown)
