Markdown Formatter

Transforms plain text or markdown into well-structured, reader-friendly markdown. The goal is to help readers quickly grasp key points, highlights, and structure — without changing any original content.

Core principle: Only adjust formatting and fix obvious typos. Never add, delete, or rewrite content.

User Input Tools

When this skill prompts the user, follow this tool-selection rule (priority order):

Prefer built-in user-input tools exposed by the current agent runtime — e.g., AskUserQuestion, request_user_input, clarify, ask_user, or any equivalent.
Fallback: if no such tool exists, emit a numbered plain-text message and ask the user to reply with the chosen number/answer for each question.
Batching: if the tool supports multiple questions per call, combine all applicable questions into a single call; if only single-question, ask them one at a time in priority order.

Concrete AskUserQuestion references below are examples — substitute the local equivalent in other runtimes.

Script Directory

Scripts in scripts/ subdirectory. {baseDir} = this SKILL.md's directory path. Resolve ${BUN_X} runtime: if bun installed → bun; if npx available → npx -y bun; else suggest installing bun. Replace {baseDir} and ${BUN_X} with actual values.

Script	Purpose
`scripts/main.ts`	Main entry point with CLI options (uses remark-cjk-friendly for CJK emphasis)
`scripts/quotes.ts`	Replace ASCII quotes with fullwidth quotes
`scripts/autocorrect.ts`	Add CJK/English spacing via autocorrect

Preferences (EXTEND.md)

Check EXTEND.md in priority order — the first one found wins:

Priority	Path	Scope
1	`.baoyu-skills/baoyu-format-markdown/EXTEND.md`	Project
2	`${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-format-markdown/EXTEND.md`	XDG
3	`$HOME/.baoyu-skills/baoyu-format-markdown/EXTEND.md`	User home

If none found, use defaults — no first-time setup required for this skill.
