ascii-ansi-colorizer（Ascii Ansi 着色器）

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

1. Output both coloredText and plainTextFallback.
2. 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.
