Mermaid syntax reference for writing or fixing a diagram in an artefact: flowchart, sequence, class, state, ER, Gantt, C4, mindmap, timeline and the other diagram types, node shapes, styling, theming, and why a diagram fails to render. Not needed for PlantUML (plantuml-syntax), or when the request is for a governed diagram artefact with document control, which /arckit:diagram produces.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Mermaid Syntax Reference A comprehensive reference for all 23 Mermaid diagram types plus configuration and theming. This skill provides official Mermaid syntax documentation sourced from the [mermaid-skill](https://github.com/WH-2099/mermaid-skill) project (auto-synced from upstream Mermaid docs). **This skill ships reference material, not runnable scripts.** Read the relevant reference file with `Read`, apply the syntax, and write the diagram into the user's artefact. Do not `Bash`-execute anything from `references/` — they are Mermaid syntax docs, not commands. To look up syntax for a specific diagram type, identify the type from the table below and read the corresponding reference file. ## Supported Diagram Types Select the appropriate diagram type and read the corresponding reference file: | Type | Reference | ArcKit Commands Using It | | ---- | --------- | ------------------------ | | Flowchart | [flowchart.md](references/flowchart.md) | `/arckit:diagram`, `/arckit:dfd`, `/arckit:roadmap`, `/arckit:plan`, `/arckit:backlog`, `/arckit:strategy`, `/arckit:story`, `/arckit:jsp-936` | …

How to install
mdr add tractorjuice/arckit-claude/mermaid-syntax@sha256:4b56b67aa11ef726The line at the top of this page pins the label git:20261001.754c23b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
