diagram-graphviz SKILL.md skillA
diagram-graphviz from spoon94/skill-vault is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add spoon94/skill-vault/diagram-graphviz@git:20260919.3062d6bPins git:20260919.3062d6b in mdr.lock. Pin the fingerprint instead.

Create directed/undirected graphs using DOT language with automatic layout. Best for dependency trees, call graphs, package hierarchies, and module relationships requiring fine-grained edge routing.
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
# Graphviz DOT Diagram Generator
> **Important:** Use ` ```dot ` as the code fence identifier, NOT ` ```graphviz `.
**Quick Start:** Choose `digraph` (directed) or `graph` (undirected) → Define nodes with attributes (shape, color, label) → Connect with `->` or `--` → Set layout (rankdir, spacing) → Wrap in ` ```dot ` fence. Default: top-to-bottom (`rankdir=TB`), cluster names must start with `cluster_`, use semicolons.

## Critical Syntax Rules
### Rule 1: Cluster Naming
```
❌ subgraph backend { } → Won't render as box
✅ subgraph cluster_backend { } → Must start with cluster_
```
### Rule 2: Node IDs with Spaces
```
❌ API Gateway [label="API"]; → Invalid ID
✅ "API Gateway" [label="API"]; → Quote the ID
✅ api_gateway [label="API Gateway"]; → Use underscore ID
```
### Rule 3: Edge Syntax Difference
```
digraph: A -> B; → Directed arrow
graph: A -- B; → Undirected line
```
### Rule 4: Attribute Syntax
```
❌ node [shape=box color=red] → Missing comma
✅ node [shape=box, color=red]; → Comma separated
```
### Rule 5: HTML Labels
```
✅ shape=plaintext for HTML labels
✅ Use < > not " " for HTML content
```

How to install
mdr add spoon94/skill-vault/diagram-graphviz@sha256:108bbbe8288eba6cThe line at the top of this page pins the label git:20260919.3062d6b, 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.
