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)

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