This file is byte-identical to the first copy the registry indexed, one of 3 copies on public GitHub. Same content hash, same audit grade.

common-architecture-diagramming is agent-read markdown (skill) from hoangnguyen0403/agent-skills-standard: Draw architecture diagrams as editable draw.io files with a fixed house style, C4 levels, and evidence-tagged shapes. Use when producing a system context, container, deployment, data flow, sequence, or state diagram, or redrawing an ASCII or Mermaid one..

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

# Architecture Diagramming Standard

## **Priority: P1 (HIGH)**

## Pipeline

Never hand-write mxGraph XML. Write a spec; the scripts own every visual decision,
so diagrams stay identical across authors, repositories, and sessions.

1. Write `spec.json` — schema in [diagram-spec.md](references/diagram-spec.md). For an ERD,
   generate it: `python3 scripts/schema_to_spec.py db/schema.sql --title "<System> — ERD" -o spec.json`
2. `python3 scripts/validate_spec.py spec.json`
3. `python3 scripts/render_drawio.py spec.json -o docs/architecture/<slug>.drawio --strict`
   (exit 2 = a layout finding; change the spec, per [layout-rules.md](references/layout-rules.md))
4. Export the image: a draw.io MCP tool if the session has one, else
   `python3 scripts/export_drawio.py docs/architecture/<slug>.drawio -f png -o docs/architecture/<slug>.png`,
   else ship the `.drawio` and say the image was not exported. See [export paths](references/mermaid-fallback.md).

Commit the `.drawio` as the source of truth; the image is a copy for a deck.
