ascii-diagram-boxflow

When to use this skill

CRITICAL TRIGGER RULE

• Use this skill ONLY when the user explicitly mentions the exact skill name: ascii-diagram-boxflow.

Trigger phrases include:

• "ascii-diagram-boxflow"
• "use ascii-diagram-boxflow"
• "用 ascii-diagram-boxflow 画 ASCII 流程图/框图"
• "使用 ascii-diagram-boxflow 生成 box + 箭头连接图"

Boundary

• ASCII output only. Do not output Mermaid/PlantUML.
• Recommended nodes <= 12; if larger, split into sub-diagrams.
• Auto-layout is best-effort for linear and simple branching. Complex layouts require manual ordering or splitting.

How to use this skill

Inputs

• nodes (node list; names required)
• edges (connections: from/to)
• direction (TB | LR, default TB)
• width (default 80)
• boxWidth (default 16)
• numbering (default false)

Outputs (required)

• diagram (ASCII-only)
• layoutRules (box width + arrow/line rules)
• splitAdvice (how to split complex diagrams)

Script

• scripts/boxflow.py: best-effort for linear flows and single 2-way branching

Examples

• examples/login-flow.md

Inline Example

Input: nodes=[Login, Validate, Dashboard], edges=[Login->Validate, Validate->Dashboard], direction=TB:

+----------------+
|     Login      |
+----------------+
        |
        v
+----------------+
|   Validate     |
+----------------+
        |
        v
+----------------+
|   Dashboard    |
+----------------+

Long name truncation (boxWidth=16): "Authentication Service" becomes "Authenticati...".

Quality checklist

1. Arrow direction is unambiguous; avoid crossings
2. Line width <= width; no trailing spaces
3. Long node names must be truncated or wrapped consistently
