SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Fixes messy, misaligned, or inconsistent ASCII and box-drawing diagrams inside fenced code blocks in markdown files so diagrams render correctly in any monospace font and nested structures stay aligned.

Core Features & Use Cases

  • Beautify existing diagrams by normalizing line widths, aligning vertical borders, fixing nested box indentation, and enforcing consistent padding and symmetry.
  • Generate new ASCII diagrams from textual specifications using Unicode box-drawing characters and programmatic helpers for precise column math.
  • Includes a Python validator that detects width mismatches, missing borders, padding issues, and nesting problems and can auto-fix or rebuild nested structures.
  • Use cases: clean up documentation diagrams, standardize architecture or flow charts in README files, and generate readable diagrams from user descriptions.

Quick Start

Use the skill to beautify the ASCII diagrams in myfile.md and write back the validated, aligned diagrams using the provided Python validator.

FAQPage Schema
How do I fix misaligned ASCII diagrams in markdown files?

Fix misaligned ASCII diagrams in markdown files by normalizing line widths, aligning vertical borders, and enforcing consistent padding. A Python validator detects width mismatches and nesting problems, automatically rebuilding nested structures to ensure diagrams render correctly in monospace fonts.

How do I generate new ASCII flow charts from text descriptions?

Generate new ASCII flow charts from text descriptions using Unicode box-drawing characters and programmatic helpers. The skill calculates precise column math to produce readable architecture diagrams with uniform line widths and consistent symmetry for your README files.

Why do my box-drawing characters render with broken vertical borders in markdown?

Box-drawing characters render with broken vertical borders due to inconsistent line widths and missing padding. A validator script detects these width mismatches and nesting problems, enforcing uniform padding and aligning borders so diagrams render correctly in any monospace font.

Can I use a script to automatically validate and fix ASCII art alignment in documentation?

You can use the included Python validator script to automatically validate and fix ASCII art alignment in documentation. It detects width mismatches, missing borders, and padding issues, then auto-fixes or rebuilds nested box-drawing structures inside fenced code blocks.

What is the best way to standardize architecture diagrams in README files?

The best way to standardize architecture diagrams in README files is applying a Python validator that enforces uniform line widths, vertical border alignment, and consistent padding. This ensures box-drawing characters render correctly across any monospace font environment.

Does the ASCII art beautifier work with existing fenced code blocks in markdown?

The ASCII art beautifier works directly with existing fenced code blocks in markdown. It targets blocks containing Unicode box-drawing characters, detecting width mismatches and nesting problems to clean up messy documentation diagrams and write back validated, aligned structures.
