Markdown Writer

Create professional, well-structured Markdown documents following enterprise best practices with proper metadata, versioning, and attribution.

Frontmatter (MANDATORY)

Every markdown document MUST start with YAML frontmatter:

---
title: "Document Title"
description: "One-sentence summary of the document purpose"
author: "{{author_name}}"
date: "YYYY-MM-DD"
version: "1.0.0"
status: "draft | review | approved | archived"
tags: ["tag1", "tag2"]
---

Versioning Rules

Use Semantic Versioning:

• Major (X.0.0): Breaking changes, full rewrites, scope changes
• Minor (1.X.0): New sections, significant content additions
• Patch (1.0.X): Typos, formatting fixes, minor clarifications

Change Log Table

For documents that evolve over time, include a change log after the frontmatter:

## Change Log

| Version | Date | Author | Changes |
|---------|------|--------|---------|
| 1.0.0 | 2026-03-04 | {{author_name}} | Initial version |

Document Structure

Standard Structure (all document types)

---
[frontmatter]
---

# Document Title

> One-sentence purpose statement.

## Change Log
[version table]

## Table of Contents
[auto or manual TOC]

## 1. Section Title
[content]

### 1.1 Subsection
[content]

## 2. Next Section
[content]

## References
[cited sources with hyperlinks]

Heading Rules

• # H1 — document title only (exactly one per document)
• ## H2 — major sections (numbered: ## 1. Introduction)
• ### H3 — subsections (numbered: ### 1.1 Overview)
• #### H4 — sub-subsections (use sparingly)
• Never skip heading levels (no H1 → H3)

Content Guidelines

Text

• Keep paragraphs under 4 sentences
• Use active voice: "The system processes..." not "The data is processed by..."
• One idea per paragraph
• Use bold for key terms on first introduction: Model Context Protocol (MCP)
• Use inline code for technical terms: docker compose up, SKILL.md

Lists

• Use bullet lists (-) for unordered items (3+ items)
• Use numbered lists (1.) for sequential steps
• Keep list items parallel in structure (all start with verbs, or all are nouns)
• Nest at most 2 levels deep

Tables

• Use tables for structured data with 3+ columns
• Always include a header row
• Align columns consistently (left for text, right for numbers)
• Keep cell content concise (< 50 chars per cell)

| Feature | Status | Owner |
|---------|--------|-------|
| Auth module | Done | @jane |
| API gateway | In progress | @john |

Code Blocks

• Always specify the language for syntax highlighting: ```typescript
• Keep code blocks under 30 lines — split larger examples
• Add a brief description before each code block
• Use inline code for short references: variable, function()

Links and References

• Use descriptive link text: MCP SDK documentation not click here
• External links: always include the full URL
• Internal links: use relative paths from document root
• All metrics, statistics, or market claims MUST have source hyperlinks
• Add a ## References section at the end with numbered citations

Images and Diagrams

• Use descriptive alt text that explains the diagram or screenshot purpose
• Store images in an img/ or assets/ subfolder
• Prefer Mermaid diagrams over images when possible (version-controlled, editable)

Document Types

Type	Key Sections	Example
README	Overview, Quick Start, Setup, Usage, Contributing	Project landing page
ADR	Status, Context, Decision, Consequences	Architecture Decision Record
Specification	Overview, Requirements, Design, API, Data Model	Technical spec
Guide	Prerequisites, Steps, Troubleshooting, FAQ	How-to guide
Changelog	Version entries with Added/Changed/Removed	Release notes
Runbook	Symptoms, Diagnosis, Resolution, Prevention	Incident response
RFC	Problem, Proposal, Alternatives, Decision	Request for comments

ADR Template

---
title: "ADR-NNN: Decision Title"
author: "{{author_name}}"
date: "YYYY-MM-DD"
version: "1.0.0"
status: "proposed | accepted | deprecated | superseded"
tags: ["adr", "architecture"]
---

# ADR-NNN: Decision Title

## Status
Accepted

## Context
[What is the issue or problem that motivates this decision?]

## Decision
[What is the change proposed or decided?]

## Consequences
[What are the positive and negative results of this decision?]

## References
[Links to related ADRs, specs, or external resources]

Factual Integrity

• NEVER fabricate metrics, KPIs, ROI figures, market data, or statistics
• Only use data from: workspace context, user-provided materials, or credible official sources
• Credible sources: Gartner, Forrester, IDC, McKinsey, Microsoft Learn, GitHub Blog, Anthropic Blog, IEEE, ACM, HBR, official vendor docs
• Every data claim MUST include a hyperlink to its source
• If no credible source exists, state as assumption or omit entirely
• Add a References section at the end of every document

Versioning & Archiving

• Filename pattern: {Title}_v{version}_{YYYY-MM-DD}.md
• Save to: output/md/
• Before overwriting an existing file, move the previous version to output/md/archive/
• YAML frontmatter MUST include version, date, and author fields
• Update the Change Log table with every new version

Quality Checklist

• YAML frontmatter present with title, author, date, version, status
• Exactly one H1 (document title)
• Heading levels are sequential (no skipping)
• Table of Contents present (for documents > 3 sections)
• Change Log present (for versioned documents)
• All code blocks have language specified
• All links are descriptive (no "click here")
• All data claims have source hyperlinks
• References section present with cited sources
• Content is in English
• No placeholder text (TODO, TBD, [fill in])
• Paragraphs are under 4 sentences
• Lists are parallel in structure
• Filename follows {Title}_v{version}_{date}.md pattern
• Saved to output/md/ with previous version archived
