# Diagramming

Owns repo-local diagramming guidance for draw.io and Mermaid workflows. Use this

skill for diagram source edits, preview/export decisions, layout checks,

color/asset conventions, and diagram-focused validation.

## 1. Use For

- draw.io `.drawio` source creation, editing, review, and export.

- draw.io layout, color palette, shape vocabulary, and AWS icon usage.

- Mermaid diagrams in Quarto revealjs `.qmd` files.

- Mermaid CLI preview, `%%{init}%%` configuration, CSS overrides, and layout

validation.

- Diagram-focused scripts and reference assets.

## 2. Do Not Use For

- Data-platform workflows; use `data-platform`.

- GitHub issue, PR, review, or public-surface mechanics; use `collaboration`.

- Generic Bash, Python, Nix, Markdown, or implementation-loop work; use

`programming`.

- Agent harness runtime, hooks, postman routing, or installed agent outputs;

use `dotfiles`.

## 3. Workflow

1. Inspect the diagram source, nearby conventions, and `git status`.

2. Choose the focused reference below before editing or validating diagrams.

3. Preserve editable source files; treat generated exports as reproducible

outputs unless the surrounding workflow requires them.

4. Verify rendered dimensions, text contrast, and overlap when diagram layout

changes are user-visible.

5. Run the nearest diagram or Markdown checks before reporting success.
