vertical-font-conversion
Local-only skill for converting horizontal Chinese fonts into high-quality vertical-reading TTF fonts with a preview-first workflow, grouped glyph rules, and local audit/test artifacts. Use when the user asks to make a 竖版字体 / 竖排 TTF, fix vertical punctuation, quotes, ellipsis, Latin, or digits, generate test images, or explicitly asks for Vertical Font Conversion.
Install via CLI (Recommended)

Use this skill when the task is about turning a horizontal font into a vertical-reading TTF font, or adjusting an existing vertical font result.
This skill is intentionally local-only. It focuses on source checking, grouped conversion, preview generation, local audit, and local test artifacts. It does not include remote conversion services, cloud uploads, or device-transfer steps.

竖版字体转换
What this skill covers
- Source font precheck before vertical conversion
- Local vertical TTF production workflow
- Stable glyph-group handling rules
- Horizontal and vertical browser preview generation before delivery
- Reader test TXT generation
- Local audit for representative glyph placement
- Grouped conversion aimed at high-satisfaction vertical TTF output
Trigger conditions
Activate this skill when the user asks for any of the following:
- “制作竖版字体”
- “做竖排 ttf”
- “制作竖版 TTF”
- “改竖排标点 / 引号 / 省略号 / 西文 / 数字”
- “启动 Vertical Font Conversion”
- “按竖版字体转换流程来”
Default execution meaning
Unless the user explicitly asks to skip steps, “use Vertical Font Conversion” means:
- check the source font first
- make a horizontal preview first
- wait for user confirmation before building the vertical TTF
- make a vertical preview before delivering the font
- generate a reader test TXT
- stay fully local: horizontal preview, vertical TTF, vertical preview, reader test TXT, and audit output when needed
Mandatory workflow
Follow this order unless the user explicitly asks to skip steps:
- Read the source horizontal TTF and check that the font opens normally and is not obviously broken.
- Generate a browser test image from the original horizontal font first.
- The preview must include:
- Chinese body text
- Latin letters
- Arabic digits
- single-point punctuation
- book-title marks / quotes / brackets
- dash / ellipsis
- one mixed-script sentence
- Ask the user to judge whether the source font itself is worth continuing.
- If confirmed, make the vertical TTF by glyph groups.
- Do not send the TTF immediately. Generate and show a browser test image for the vertical result first.
- Also generate a TXT test file for reader-side validation.
- Only after user confirmation, send the TTF and related local test artifacts.
If the original horizontal font already has obvious missing punctuation / Latin / digits / rendering defects, stop and tell the user it is not a good source candidate.
