Generates clean, syntactically valid Mermaid.js diagrams for ERDs, system architecture, sequence flows, class diagrams, and C4 component models directly inside Markdown documents.
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 Architect
Specialized skill for creating robust, syntactically correct Mermaid.js diagrams for Markdown documentation, PR descriptions, and architectural blueprints.
## Syntax Best Practices
1. **Quote Node Labels**: Always quote labels containing special characters, brackets, or parentheses:
```mermaid
graph TD
A["Client (Browser / Mobile)"] --> B["API Gateway (Hono / Next.js)"]
```
2. **Cardinality in ERDs**:
- `||--||` : Exactly one to one
- `||--o{` : One to zero-or-more
- `||--|{` : One to one-or-more
- `}o--o{` : Zero-or-more to zero-or-more
---
## Supported Diagram Types
### 1. Entity Relationship Diagram (ERD)
```mermaid
erDiagram
USER ||--o{ POST : writes
USER {
uuid id PK
string email UK
datetime created_at
}
POST {
uuid id PK
uuid author_id FK
string title
text content
}
```
### 2. Sequence Diagram (Auth & API Flow)
```mermaid
sequenceDiagram
autonumber
actor User
participant Client as Client App
participant Auth as Better Auth Server
participant DB as Database
User->>Client: Click Login with Google
Client->>Auth: Redirect to /api/auth/sign-in/social

How to install
mdr add smicolon/ai-kit/mermaid-architect@sha256:ba8b9577bc981b2fThe line at the top of this page pins the label v1.0.0, 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.
