ascii-ansi-colorizer

When to use this skill

CRITICAL TRIGGER RULE

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

Trigger phrases include:

• "ascii-ansi-colorizer"
• "use ascii-ansi-colorizer"
• "用 ascii-ansi-colorizer 给 ASCII 上色"
• "使用 ascii-ansi-colorizer 做 ANSI 渐变/彩虹"

Boundary

• This skill only adds color to existing text. It does not generate the ASCII art itself (pair with ascii-cli-logo-banner if needed).
• Required outputs: coloredText + plainTextFallback.
• ANSI must not break alignment: do not colorize spaces by default; colorize visible characters only.

How to use this skill

Inputs

• textOrAscii (required)
• palette (rainbow | gradient | brandColors)
• direction (leftToRight | topToBottom, default leftToRight)
• colorDepth (ansi16 | ansi256 | truecolor, default ansi256)
• scope (logoOnly | highlightsOnly | fullText, default logoOnly)

Outputs (required)

• coloredText: ANSI-colored output
• plainTextFallback: no-color fallback (identical content, no ANSI)
• compatNotes: copy/paste and redirection guidance (NO_COLOR / --no-color suggestions)

Steps

1. Pick colorDepth (default: ansi256).
2. Choose a stable coloring strategy:
   • Column-wise gradients (leftToRight) are usually the safest
   • Colorize non-space characters only
3. Output both coloredText and plainTextFallback.
4. Provide no-color guidance (semantic suggestions): NO_COLOR / --no-color.

Script

• scripts/colorize.py: apply ANSI 256 gradient or rainbow to stdin

Examples

• examples/gradient.md

Quality checklist

1. Removing ANSI keeps the same readable content (plainTextFallback).
2. Alignment does not change after coloring.
3. Colors should not overpower the informational lines.

常见陷阱 (Gotchas)

1. 版本兼容性：注意框架版本与依赖库的兼容性，不同版本 API 可能有差异
2. 配置文件格式：配置文件格式错误是最常见的问题，建议使用编辑器的语法检查
3. 环境变量：确保所有必要的环境变量已正确设置，敏感信息不要硬编码
4. 依赖冲突：多版本共存时注意依赖冲突，使用 lock 文件锁定版本
5. 性能陷阱：大数据量场景下注意性能优化，避免 N+1 查询等常见问题
