Generate perfectly aligned ASCII diagrams — architecture, flow, sequence, box-and-arrow. Uses a programmatic character-grid approach so alignment is guaranteed by math, not token prediction. Includes post-render verification.
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
# /ascii-diagram — Perfectly Aligned ASCII Diagrams ## Orientation **Use when:** - The user wants any kind of text/ASCII diagram: architecture, flow, sequence, box-and-arrow, tree, table, org chart, network topology - A diagram needs to be embedded in markdown, code comments, or plain text - Visual alignment matters **Do NOT use when:** - The user wants an image (suggest Mermaid, PlantUML, or an image tool instead) - The diagram is trivial (a single box or a one-line arrow) **What this skill needs:** - A description of what to diagram - Optional: preferred style (single-line `+--+`, double-line `╔══╗`, rounded `╭──╮`, heavy `┏━━┓`) - Optional: target width constraint ## Protocol ### Step 1: PLAN THE LAYOUT Before writing ANY characters, plan the diagram structurally: 1. **Identify elements**: List every box/node and its label text 2. **Identify connections**: List every arrow/line between elements, with optional labels 3. **Choose layout direction**: left-to-right, top-to-bottom, or mixed 4. **Calculate dimensions**: - Each box width = max label line length + 4 (2 padding + 2 border) - Each box height = label line count + 2 (top + bottom border) …

How to install
mdr add sethgammon/citadel/ascii-diagram@sha256:5f60084f1e0d06a5The line at the top of this page pins the label git:20260611.0f3f8e7, 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.
