Markdown and Mermaid Writing

Overview

This skill teaches you — and enforces a standard for — creating scientific documentation using markdown with embedded Mermaid diagrams as the default and canonical format.

The core bet: a relationship expressed as a Mermaid diagram inside a .md file is more valuable than any image. It is text, so it diffs cleanly in git. It requires no build step. It renders natively on GitHub, GitLab, Notion, VS Code, and any markdown viewer. It uses fewer tokens than a prose description of the same relationship. And it can always be converted to a polished image later — but the text version remains the source of truth.

"The more you get your reports and files in .md in just regular text, which mermaid is as well as being a simple 'script language'. This just helps with any downstream rendering and especially AI generated images (using mermaid instead of just long form text to describe relationships < tokens). Additionally mermaid can render along with markdown for easy use almost anywhere by humans or AI."

— Clayton Young (@borealBytes), K-Dense Discord, 2026-02-19

When to Use This Skill

Use this skill when:

Creating any scientific document — reports, analyses, manuscripts, methods sections
Writing any documentation — READMEs, how-tos, decision records, project docs
Producing any diagram — workflows, data pipelines, architectures, timelines, relationships
Generating any output that will be version-controlled — if it's going into git, it should be markdown
Working with any other skill — this skill defines the documentation layer that wraps every other output
Someone asks you to "add a diagram" or "visualize the relationship" — Mermaid first, always

Do NOT start with Python matplotlib, seaborn, or AI image generation for structural or relational diagrams. Those are Phase 2 and Phase 3 — only used when Mermaid cannot express what's needed (e.g., scatter plots with real data, photorealistic images).

🎨 The Source Format Philosophy

Why text-based diagrams win

What matters	Mermaid in Markdown	Python / AI Image
Git diff readable	✅	❌ binary blob
Editable without regenerating	✅	❌
Token efficient vs. prose	✅ smaller	❌ larger
Renders without a build step	✅	❌ needs hosting
Parseable by AI without vision	✅	❌
Works in GitHub / GitLab / Notion	✅	⚠️ if hosted
Accessible (screen readers)	✅ accTitle/accDescr	⚠️ needs alt text
Convertible to image later	✅ anytime	— already image

Phase 1 is mandatory. Even if you proceed to Phase 2 or 3, the Mermaid source stays committed.

What Mermaid can express

Mermaid covers 24 diagram types. Almost every scientific relationship fits one:

Use case	Diagram type	File
Experimental workflow / decision logic	Flowchart	`references/diagrams/flowchart.md`
Service interactions / API calls / messaging	Sequence	`references/diagrams/sequence.md`
Data model / schema	ER diagram	`references/diagrams/er.md`
State machine / lifecycle	State	`references/diagrams/state.md`
Project timeline / roadmap	Gantt	`references/diagrams/gantt.md`
Proportions / composition	Pie	`references/diagrams/pie.md`
System architecture (zoom levels)	C4	`references/diagrams/c4.md`
Concept hierarchy / brainstorm	Mindmap	`references/diagrams/mindmap.md`
Chronological events / history	Timeline	`references/diagrams/timeline.md`
Class hierarchy / type relationships	Class	`references/diagrams/class.md`
User journey / satisfaction map	User Journey	`references/diagrams/user_journey.md`
Two-axis comparison / prioritization	Quadrant	`references/diagrams/quadrant.md`
Requirements traceability	Requirement	`references/diagrams/requirement.md`
Flow magnitude / resource distribution	Sankey	`references/diagrams/sankey.md`
Numeric trends / bar + line charts	XY Chart	`references/diagrams/xy_chart.md`
Component layout / spatial arrangement	Block	`references/diagrams/block.md`
Work item status / task columns	Kanban	`references/diagrams/kanban.md`
Cloud infrastructure / service topology	Architecture

💡 Pick the right type, not the easy one. Don't default to flowcharts for everything. A timeline beats a flowchart for chronological events. A sequence beats a flowchart for service interactions. Scan the table and match.

🔧 Core workflow

Step 1: Identify the document type

Check if a template exists before writing from scratch:

Document type	Template
Pull request record	`templates/pull_request.md`
Issue / bug / feature request	`templates/issue.md`
Sprint / project board	`templates/kanban.md`
Architecture decision (ADR)	`templates/decision_record.md`
Presentation / briefing	`templates/presentation.md`
Research paper / analysis	`templates/research_paper.md`
Project documentation	`templates/project_documentation.md`
How-to / tutorial	`templates/how_to_guide.md`
Status report	`templates/status_report.md`

Step 2: Read the style guide

Before writing any .md file: read references/markdown_style_guide.md.

Key rules to internalize:

One H1 per document — the title. Never more.
Emoji on H2 headings only — one emoji per H2, none in H3/H4
Cite everything — every external claim gets a footnote [^N] with full URL
Bold sparingly — max 2-3 bold terms per paragraph, never full sentences
Horizontal rule after every </details> — mandatory
Tables over prose for comparisons, configurations, structured data
Diagrams over walls of text — if it describes flow, structure, or relationships, add Mermaid

Step 3: Pick the diagram type and read its guide

Before creating any Mermaid diagram: read references/mermaid_style_guide.md.

Then open the specific type file (e.g., references/diagrams/flowchart.md) for the exemplar, tips, and copy-paste template.

Mandatory rules for every diagram:

accTitle: Short Name 3-8 Words
accDescr: One or two sentences explaining what this diagram shows.

No %%{init} directives — breaks GitHub dark mode
No inline style — use classDef only
One emoji per node max — at the start of the label
snake_case node IDs — match the label

Step 4: Write the document

Start from the template. Apply the markdown style guide. Place diagrams inline with related text — not in a separate "Figures" section.

Step 5: Commit as text

The .md file with embedded Mermaid is what gets committed. If you also generated a PNG or AI image, those are supplementary — the markdown is the source.

⚠️ Common pitfalls

Radar chart syntax (`radar-beta`)

WRONG:

radar
title Example
x-axis ["A", "B", "C"]
"Series" : [1, 2, 3]

CORRECT:

radar-beta
title Example
axis a["A"], b["B"], c["C"]
curve series["Series"]{1, 2, 3}
max 3

Use radar-beta not radar (the bare keyword doesn't exist)
Use axis to define dimensions, not x-axis
Use curve to define data series, not quoted labels with colon
No accTitle/accDescr — radar-beta doesn't support accessibility annotations; always add a descriptive italic paragraph above the diagram

XY Chart vs Radar confusion

Diagram	Keyword	Axis syntax	Data syntax
XY Chart (bars/lines)	`xychart-beta`	`x-axis ["Label1", "Label2"]`	`bar [10, 20]` or `line [10, 20]`
Radar (spider/web)	`radar-beta`	`axis id["Label"]`	`curve id["Label"]{10, 20}`

Forgetting `accTitle`/`accDescr` on supported types

Only some diagram types support accTitle/accDescr. For those that don't, always place a descriptive italic paragraph directly above the code block:

Radar chart comparing three methods across five performance dimensions. Note: Radar charts do not support accTitle/accDescr.

🔗 Integration with other skills

With `scientific-schematics`

scientific-schematics generates AI-powered publication-quality images (PNG). Use the Mermaid diagram as the brief for the schematic:

Workflow:
1. Create the concept as Mermaid in .md (this skill — Phase 1)
2. Describe the same concept to scientific-schematics for a polished PNG (Phase 3)
3. Commit both — the .md as source, the PNG as a supplementary figure

With `scientific-writing`

When scientific-writing produces a manuscript, all diagrams and structural figures should use this skill's standards. The writing skill handles prose and citations; this skill handles visual structure.

Workflow:
1. Use scientific-writing to draft the manuscript
2. For every figure that shows a workflow, architecture, or relationship:
   - Replace placeholder with a Mermaid diagram following this skill's guide
3. Use scientific-schematics only for figures that truly need photorealistic/complex rendering

With `literature-review`

Literature review produces summaries with lots of relationship data. Use this skill to:

Create concept maps (Mindmap) of the literature landscape
Show publication timelines (Timeline or Gantt)
Compare methodologies (Quadrant or Radar)
Diagr

## When to Use This Skill

Use this skill when:

- Creating **any scientific document** — reports, analyses, manuscripts, methods sections
- Writing **any documentation** — READMEs, how-tos, decision records, project docs
- Producing **any diagram** — workflows, data pipelines, architectures, timelines, relationships

## 🔧 Core workflow

### Step 1: Identify the document type

Check if a template exists before writing from scratch:

| Document type | Template |
| ------------------------------ | ----------------------------------------------- |
| Pull request record | `templates/pull_request.md` |
| Issue / bug / feature request | `templates/issue.md` |
| Sprint / project board | `templates/kanban.md` |
| Architecture decision (ADR) | `templates/decision_record.md` |
| Presentation / briefing | `templates/presentation.md` |
| Research paper / analysis | `templates/research_paper.md` |
| Project documentation | `templates/project_documentation.md` |
| How-to / tutorial | `templates/how_to_guide.md` |
| Status report | `templates/status_report.md` |

### Step 2: Read the style guide

Before writing any `.md` file: read `references/markdown_style_guide.md`.

Key rules to internalize:

- **One H1 per document** — the title. Never more.
- **Emoji on H2 headings only** — one emoji per H2, none in H3/H4
- **Cite everything** — every external claim gets a footnote `[^N]` with full URL
- **Bold sparingly** — max 2-3 bold terms per paragraph, never full sentences
- **Horizontal rule after every `</details>`** — mandatory
- **Tables over prose** for comparisons, configurations, structured data
- **Diagrams over walls of text** — if it describes flow, structure, or relationships, add Mermaid

### Step 3: Pick the diagram type and read its guide

Before creating any Mermaid diagram: read `references/mermaid_style_guide.md`.

Then open the specific type file (e.g., `references/diagrams/flowchart.md`) for the exemplar, tips, and copy-paste template.

Mandatory rules for every diagram:

```
accTitle: Short Name 3-8 Words
