## What it does

The rule applies to all `**/*.md` files. It prohibits top-level H1 headings because the publication title gets rendered automatically. Section hierarchies rely on `##` and `###`. Reaching H4 or H5 triggers an explicit recommendation to restructure the document. Nested lists require a two-space indent. Fenced code blocks must declare their language, like `csharp`.

Lines cannot exceed 400 characters, with soft line breaks recommended at 80 characters. Every post must open with YAML front matter containing `post_title`, `author1`, `post_slug`, `microsoft_alias`, `featured_image`, `categories`, `tags`, `ai_note`, `summary`, and `post_date`.

Validation breaks immediately if `/categories.txt` is missing from the project, because Copilot checks assigned categories against that exact file.

## Install

### GitHub Copilot (native platform)

**Manually: put the files in place**
- File: `.github/instructions/markdown-content-creation.instructions.md` — The applyTo field sets which files it applies to

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/markdown-content-creation.md` — The paths frontmatter field limits the files: move applyTo from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### Cursor

**Manually: put the files in place**
- File: `.cursor/rules/markdown-content-creation.mdc` — Frontmatter: description, globs, alwaysApply. Move applyTo from the source into globs, or the rule will not attach on its own

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/markdown-content-creation.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/markdown-content-creation.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/github/awesome-copilot/tree/HEAD/instructions/markdown-content-creation.instructions.md

## When to use it
- generate required YAML front matter fields for blog drafts
- prevent H1 headings in Markdown post bodies
- add explicit language tags to code snippets
- format table alignment and nested list indentation

## Example prompts
- Format this blog draft according to the repository Markdown rules and generate the front matter.
- Check heading hierarchy in `blog-post.md` and restructure any section deeper than H3.

# Markdown Content Rules

The following markdown content rules are enforced in the validators:

1. **Headings**: Use appropriate heading levels (H2, H3, etc.) to structure your content. Do not use an H1 heading, as this will be generated based on the title.
2. **Lists**: Use bullet points or numbered lists for lists. Ensure proper indentation and spacing.
3. **Code Blocks**: Use fenced code blocks for code snippets. Specify the language for syntax highlighting.
4. **Links**: Use proper markdown syntax for links. Ensure that links are valid and accessible.
5. **Images**: Use proper markdown syntax for images. Include alt text for accessibility.
6. **Tables**: Use markdown tables for tabular data. Ensure proper formatting and alignment.
7. **Line Length**: Limit line length to 400 characters for readability.
8. **Whitespace**: Use appropriate whitespace to separate sections and improve readability.
9. **Front Matter**: Include YAML front matter at the beginning of the file with required metadata fields.

## Formatting and Structure

Follow these guidelines for formatting and structuring your markdown content:

- **Headings**: Use `##` for H2 and `###` for H3. Ensure that headings are used in a hierarchical manner. Recommend restructuring if content includes H4, and more strongly recommend for H5.
- **Lists**: Use `-` for bullet points and `1.` for numbered lists. Indent nested lists with two spaces.
- **Code Blocks**: Use triple backticks (```) to create fenced code blocks. Specify the language after the opening backticks for syntax highlighting (e.g., `csharp`).
- **Links**: Use `[link text](URL)` for links. Ensure that the link text is descriptive and the URL is valid.
- **Images**: Use `![alt text](image URL)` for images. Include a brief description of the image in the alt text.
- **Tables**: Use `|` to create tables. Ensure that columns are properly aligned and headers are included.
- **Line Length**: Break lines at 80 characters to improve readability. Use soft line breaks for long paragraphs.
- **Whitespace**: Use blank lines to separate sections and improve readability. Avoid excessive whitespace.

## Validation Checklist
