mermaid skillA

mermaid is agent-read markdown (skill) from ulises-jeremias/agent-toolkit: 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..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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.
