WHAT — Mermaid diagrams from text (flowchart, sequence, class, state, ER, gantt, gitGraph) — Markdown-native, Git-native, MIT. Primary renderer for architecture pack; renders via GitHub native or mermaid CLI (mmdc) to SVG/PNG.
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 — Primary Diagram Renderer (WHAT) **Sources (2026-08-12):** `mermaid-js/mermaid` https://github.com/mermaid-js/mermaid MIT (Mermaid live editor https://mermaid.live); NPM `mermaid 10.x` `MIT` + `@mermaid-js/mermaid 10.9.7-preview.41` `MIT`; `docs/ARCHITECTURE.md` already authors Mermaid natively. > **Pack:** `architecture` core (`architect + ADR + TRD + threat-model + mermaid (+ C4)`) — vendor-neutral. `cloud-architecture` optional composes `cloud-design-patterns + aws-well-architected-review + mermaid`. See `docs/architecture/research-385-diagram.md` for Mermaid vs C4 vs PlantUML/Structurizr/Excalidraw decision per §44. ## When to use - Need flowchart, sequence, class, ER, gantt, gitGraph — text → SVG/PNG. - Threat-model data-flow / sequence diagrams. ## Instructions 1. **Author** Mermaid block in Markdown: ` ```mermaid` + `flowchart TD` / `sequenceDiagram` / `classDiagram` etc. 2. **Render** via GitHub native or `mmdc -i diagram.mmd -o diagram.svg` (mermaid CLI). 3. **Collaborate** with `architect` + `threat-model` (data-flow) and `c4-model` (C4-inspired via Mermaid). ## Anti-patterns - Do not add Excalidraw/draw.io binary — use Mermaid text. …

How to install
mdr add ulises-jeremias/agent-toolkit/mermaid@sha256:bd9c1c623d0c1549The line at the top of this page pins the label v1.0, 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.
