SKILL.md
| 1 | # Markdown Formatter |
| 2 | |
| 3 | 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. |
| 4 | |
| 5 | **Core principle**: Only adjust formatting and fix obvious typos. Never add, delete, or rewrite content. |
| 6 | |
| 7 | ## User Input Tools |
| 8 | |
| 9 | When this skill prompts the user, follow this tool-selection rule (priority order): |
| 10 | |
| 11 | 1. **Prefer built-in user-input tools** exposed by the current agent runtime — e.g., `AskUserQuestion`, `request_user_input`, `clarify`, `ask_user`, or any equivalent. |
| 12 | 2. **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. |
| 13 | 3. **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. |
| 14 | |
| 15 | Concrete `AskUserQuestion` references below are examples — substitute the local equivalent in other runtimes. |
| 16 | |
| 17 | ## Script Directory |
| 18 | |
| 19 | 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. |
| 20 | |
| 21 | | Script | Purpose | |
| 22 | |--------|---------| |
| 23 | | `scripts/main.ts` | Main entry point with CLI options (uses remark-cjk-friendly for CJK emphasis) | |
| 24 | | `scripts/quotes.ts` | Replace ASCII quotes with fullwidth quotes | |
| 25 | | `scripts/autocorrect.ts` | Add CJK/English spacing via autocorrect | |
| 26 | |
| 27 | ## Preferences (EXTEND.md) |
| 28 | |
| 29 | Check EXTEND.md in priority order — the first one found wins: |
| 30 | |
| 31 | | Priority | Path | Scope | |
| 32 | |----------|------|-------| |
| 33 | | 1 | `.baoyu-skills/baoyu-format-markdown/EXTEND.md` | Project | |
| 34 | | 2 | `${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-format-markdown/EXTEND.md` | XDG | |
| 35 | | 3 | `$HOME/.baoyu-skills/baoyu-format-markdown/EXTEND.md` | User home | |
| 36 | |
| 37 | If none found, use defaults — no first-time setup required for this skill. |
| 38 | |
| 39 | **EXTEND.md supports**: |
| 40 | |
| 41 | | Setting | Values | Default | Description | |
| 42 | |---------|--------|---------|-------------| |
| 43 | | `auto_select` | `true`/`false` | `false` | Skip both title and summary selection, auto-pick best | |
| 44 | | `auto_select_title` | `true`/`false` | `false` | Skip title selection only | |
| 45 | | `auto_select_summary` | `true`/`false` | `false` | Skip summary selection only | |
| 46 | | Other | — | — | Default formatting options, typography preferences | |
| 47 | |
| 48 | ## Usage |
| 49 | |
| 50 | The workflow has two phases: **Analyze** (understand the content) then **Format** (apply formatting). Claude performs content analysis and formatting (Steps 1-5), then runs the script for typography fixes (Step 6). |
| 51 | |
| 52 | ## Workflow |
| 53 | |
| 54 | ### Step 1: Read & Detect Content Type |
| 55 | |
| 56 | Read the user-specified file, then detect content type: |
| 57 | |
| 58 | | Indicator | Classification | |
| 59 | |-----------|----------------| |
| 60 | | Has `---` YAML frontmatter | Markdown | |
| 61 | | Has `#`, `##`, `###` headings | Markdown | |
| 62 | | Has `**bold**`, `*italic*`, lists, code blocks, blockquotes | Markdown | |
| 63 | | None of above | Plain text | |
| 64 | |
| 65 | **If Markdown detected, use `AskUserQuestion` to ask:** |
| 66 | |
| 67 | ``` |
| 68 | Detected existing markdown formatting. What would you like to do? |
| 69 | |
| 70 | 1. Optimize formatting (Recommended) |
| 71 | - Analyze content, improve headings, bold, lists for readability |
| 72 | - Run typography script (spacing, emphasis fixes) |
| 73 | - Output: {filename}-formatted.md |
| 74 | |
| 75 | 2. Keep original formatting |
| 76 | - Preserve existing markdown structure |
| 77 | - Run typography script only |
| 78 | - Output: {filename}-formatted.md |
| 79 | |
| 80 | 3. Typography fixes only |
| 81 | - Run typography script on original file in-place |
| 82 | - No copy created, modifies original file directly |
| 83 | ``` |
| 84 | |
| 85 | **Based on user choice:** |
| 86 | - **Optimize**: Continue to Step 2 (full workflow) |
| 87 | - **Keep original**: Skip to Step 5, copy file then run Step 6 |
| 88 | - **Typography only**: Skip to Step 6, run on original file directly |
| 89 | |
| 90 | ### Step 2: Analyze Content (Reader's Perspective) |
| 91 | |
| 92 | Read the entire content carefully. Think from a reader's perspective: what would help them quickly understand and remember the key information? |
| 93 | |
| 94 | Produce an analysis covering these dimensions: |
| 95 | |
| 96 | **2.1 Highlights & Key Insights** |
| 97 | - Core arguments or conclusions the author makes |
| 98 | - Surprising facts, data points, or counterintuitive claims |
| 99 | - Memorable quotes or well-phrased sentences (golden quotes) |
| 100 | |
| 101 | **2.2 Structure Assessment** |
| 102 | - Does the content have a clear logical flow? What is it? |
| 103 | - Are there natural section boundaries that lack headings? |
| 104 | - Are there long walls of text that could benefit from visual breaks? |
| 105 | |
| 106 | **2.3 Reader-Important Information** |
| 107 | - Actionable advice or takeaways |
| 108 | - Definitions, explanations of key concepts |
| 109 | - Lists or enumerations buried in prose |
| 110 | - Comparisons or contrasts that would be clearer as tables |
| 111 | |
| 112 | **2.4 Formatting Issues** |
| 113 | - Missing or inconsistent heading hierarchy |
| 114 | - Paragraphs that mix multiple topics |
| 115 | - Parallel items written as prose instead of lists |
| 116 | - Code, commands, or technical terms not marked as code |
| 117 | - Obvious typos or formatting errors |
| 118 | |
| 119 | **Save analysis to file**: `{original-filename}-analysis.md` |
| 120 | |
| 121 | The analysis file serves as the blueprint for Step 3. Use this format: |
| 122 | |
| 123 | ```markdown |
| 124 | # Content Analysis: {filename} |
| 125 | |
| 126 | ## Highlights & Key Insights |
| 127 | - [list findings] |
| 128 | |
| 129 | ## Structure Assessment |
| 130 | - Current flow: [describe] |
| 131 | - Suggested sections: [list heading candidates with brief rationale] |
| 132 | |
| 133 | ## Reader-Important Information |
| 134 | - [list actionable items, key concepts, buried lists, potential tables] |
| 135 | |
| 136 | ## Formatting Issues |
| 137 | - [list specific issues with location references] |
| 138 | |
| 139 | ## Typos Found |
| 140 | - [list any obvious typos with corrections, or "None found"] |
| 141 | ``` |
| 142 | |
| 143 | ### Step 3: Check/Create Frontmatter, Title & Summary |
| 144 | |
| 145 | Check for YAML frontmatter (`---` block). Create if missing. |
| 146 | |
| 147 | | Field | Processing | |
| 148 | |-------|------------| |
| 149 | | `title` | See **Title Generation** below | |
| 150 | | `slug` | Infer from file path or generate from title | |
| 151 | | `summary` | One-sentence concise summary (see **Summary Generation** below) | |
| 152 | | `description` | Longer descriptive summary (see **Summary Generation** below) | |
| 153 | | `coverImage` | Check if `imgs/cover.png` exists in same directory; if so, use relative path | |
| 154 | |
| 155 | #### Title Generation |
| 156 | |
| 157 | Whether or not a title already exists, run the title optimization flow unless `auto_select_title` is set. |
| 158 | |
| 159 | **Preparation** — read the full text and extract: |
| 160 | - Core argument (one sentence: "what is this article about?") |
| 161 | - Most impactful opinion or conclusion |
| 162 | - Reader pain point or curiosity trigger |
| 163 | - Most memorable metaphor or golden quote |
| 164 | |
| 165 | **Generate candidates** using formulas from `references/title-formulas.md`: |
| 166 | |
| 167 | 1. Select the **2-3 best-matching hook formulas** based on the article's content, tone, and structure (see "When to pick each formula" in the reference) |
| 168 | 2. Generate **1-2 straightforward titles** (descriptive or declarative, no formula — clear and accurate) |
| 169 | 3. If the user specifies a direction (e.g., "make it suspenseful"), prioritize that direction |
| 170 | 4. Total: **4-5 candidates** |
| 171 | |
| 172 | Present via `AskUserQuestion`: |
| 173 | |
| 174 | ``` |
| 175 | Pick a title: |
| 176 | |
| 177 | 1. [Hook title A] — (recommended) [formula name] |
| 178 | 2. [Hook title B] — [formula name] |
| 179 | 3. [Hook title C] — [formula name] |
| 180 | 4. [Straightforward title D] — straightforward |
| 181 | 5. [Straightforward title E] — straightforward |
| 182 | |
| 183 | Enter number, or type a custom title: |
| 184 | ``` |
| 185 | |
| 186 | Put the strongest hook first and mark it `(recommended)`. See `references/title-formulas.md` for principles and prohibited patterns. |
| 187 | |
| 188 | If the first line is an H1, extract it to frontmatter and remove it from the body. If frontmatter already has a `title`, include it as context but still generate fresh candidates — the existing title may be weak. |
| 189 | |
| 190 | **Skip behavior**: If `auto_select: true` or `auto_select_title: true`, skip the user prompt and use the top candidate directly. |
| 191 | |
| 192 | #### Summary Generation |
| 193 | |
| 194 | Generate two versions directly (no user selection), both stored in frontmatter: |
| 195 | |
| 196 | | Field | Length | Purpose | |
| 197 | |-------|--------|---------| |
| 198 | | `summary` | 1 sentence, ~50-80 chars | Concise hook — for feeds, social sharing, SEO meta | |
| 199 | | `description` | 2-3 sentences, ~100-200 chars | Richer context — for article previews, newsletter blurbs | |
| 200 | |
| 201 | **Principles**: |
| 202 | |
| 203 | - Convey **core value** to the reader, not just the topic |
| 204 | - Use concrete details (numbers, outcomes, specific methods) over vague descriptions |
| 205 | - `summary` should be punchy and self-contained; `description` can expand with supporting details |
| 206 | - If frontmatter already has `summary` or `description`, keep the existing one and only generate the missing field |
| 207 | |
| 208 | **Prohibited patterns**: |
| 209 | |
| 210 | - "This article introduces...", "This article explores..." |
| 211 | - Pure topic description without value proposition |
| 212 | - Repeating the title in different words |
| 213 | |
| 214 | Once the title is in frontmatter, the body should NOT contain an H1 (avoid duplication). |
| 215 | |
| 216 | ### Step 4: Format Content |
| 217 | |
| 218 | Apply formatting guided by the Step 2 analysis. The goal is making the content scannable and the key points impossible to miss. |
| 219 | |
| 220 | **Formatting toolkit:** |
| 221 | |
| 222 | | Element | When to use | Format | |
| 223 | |---------|-------------|--------| |
| 224 | | Headings | Natural topic boundaries, section breaks | `##`, `###` hierarchy | |
| 225 | | Bold | Key conclusions, important terms, core takeaways | `**bold**` | |
| 226 | | Unordered lists | Parallel items, feature lists, examples | `- item` | |
| 227 | | Ordered lists | Sequential steps, ranked items, procedures | `1. item` | |
| 228 | | Tables | Comparisons, structured data, option matrices | Markdown table | |
| 229 | | Code | Commands, file paths, technical terms, variable names | `` `inline` `` or fenced blocks | |
| 230 | | Blockquotes | Notable quotes, important warnings, cited text | `> quote` | |
| 231 | | Separators | Major topic transitions | `---` | |
| 232 | |
| 233 | **Formatting principles — what NOT to do:** |
| 234 | - Do NOT add sentences, explanations, or commentary |
| 235 | - Do NOT delete or shorten any content |
| 236 | - Do NOT rephrase or rewrite the author's words |
| 237 | - Do NOT add headings that editorialize (e.g., "Amazing Discovery" — use neutral descriptive headings) |
| 238 | - Do NOT over-format: not every sentence needs bold, not every paragraph needs a heading |
| 239 | |
| 240 | **Formatting principles — what TO do:** |
| 241 | - Preserve the author's voice, tone, and every word |
| 242 | - **Bold key conclusions and core takeaways** — the sentences a reader would highlight |
| 243 | - Extract parallel items from prose into lists only when the structure is clearly there |
| 244 | - Add headings where the topic genuinely shifts — prefer vivid, specific headings over generic ones (e.g., "3 天搞定 vs 传统方案" over "方案对比") |
| 245 | - Use tables for comparisons or structured data buried in prose |
| 246 | - Use blockquotes for golden quotes, memorable statements, or important warnings |
| 247 | - Fix obvious typos (based on Step 2 findings) |
| 248 | |
| 249 | ### Step 5: Save Formatted File |
| 250 | |
| 251 | Save as `{original-filename}-formatted.md` |
| 252 | |
| 253 | **Backup existing file:** |
| 254 | |
| 255 | ```bash |
| 256 | if [ -f "{filename}-formatted.md" ]; then |
| 257 | mv "{filename}-formatted.md" "{filename}-formatted.backup-$(date +%Y%m%d-%H%M%S).md" |
| 258 | fi |
| 259 | ``` |
| 260 | |
| 261 | ### Step 6: Execute Typography Script |
| 262 | |
| 263 | Run the formatting script on the output file: |
| 264 | |
| 265 | ```bash |
| 266 | ${BUN_X} {baseDir}/scripts/main.ts {output-file-path} [options] |
| 267 | ``` |
| 268 | |
| 269 | **Script Options:** |
| 270 | |
| 271 | | Option | Short | Description | Default | |
| 272 | |--------|-------|-------------|---------| |
| 273 | | `--quotes` | `-q` | Replace ASCII quotes with fullwidth quotes `"..."` | false | |
| 274 | | `--no-quotes` | | Do not replace quotes | | |
| 275 | | `--spacing` | `-s` | Add CJK/English spacing via autocorrect | true | |
| 276 | | `--no-spacing` | | Do not add CJK/English spacing | | |
| 277 | | `--emphasis` | `-e` | Fix CJK emphasis punctuation issues | true | |
| 278 | | `--no-emphasis` | | Do not fix CJK emphasis issues | | |
| 279 | |
| 280 | **Examples:** |
| 281 | |
| 282 | ```bash |
| 283 | # Default: spacing + emphasis enabled, quotes disabled |
| 284 | ${BUN_X} {baseDir}/scripts/main.ts article.md |
| 285 | |
| 286 | # Enable all features including quote replacement |
| 287 | ${BUN_X} {baseDir}/scripts/main.ts article.md --quotes |
| 288 | |
| 289 | # Only fix emphasis issues, skip spacing |
| 290 | ${BUN_X} {baseDir}/scripts/main.ts article.md --no-spacing |
| 291 | ``` |
| 292 | |
| 293 | **Script performs (based on options):** |
| 294 | 1. Fix CJK emphasis/bold punctuation issues (default: enabled) |
| 295 | 2. Add CJK/English mixed text spacing via autocorrect (default: enabled) |
| 296 | 3. Replace ASCII quotes with fullwidth quotes (default: disabled) |
| 297 | 4. Format frontmatter YAML (always enabled) |
| 298 | |
| 299 | ### Step 7: Completion Report |
| 300 | |
| 301 | Display a report summarizing all changes made: |
| 302 | |
| 303 | ``` |
| 304 | **Formatting Complete** |
| 305 | |
| 306 | **Files:** |
| 307 | - Analysis: {filename}-analysis.md |
| 308 | - Formatted: {filename}-formatted.md |
| 309 | |
| 310 | **Content Analysis Summary:** |
| 311 | - Highlights found: X key insights |
| 312 | - Golden quotes: X memorable sentences |
| 313 | - Formatting issues fixed: X items |
| 314 | |
| 315 | **Changes Applied:** |
| 316 | - Frontmatter: [added/updated] (title, slug, summary) |
| 317 | - Headings added: X (##: N, ###: N) |
| 318 | - Bold markers added: X |
| 319 | - Lists created: X (from prose → list conversion) |
| 320 | - Tables created: X |
| 321 | - Code markers added: X |
| 322 | - Blockquotes added: X |
| 323 | - Typos fixed: X [list each: "original" → "corrected"] |
| 324 | |
| 325 | **Typography Script:** |
| 326 | - CJK spacing: [applied/skipped] |
| 327 | - Emphasis fixes: [applied/skipped] |
| 328 | - Quote replacement: [applied/skipped] |
| 329 | ``` |
| 330 | |
| 331 | Adjust the report to reflect actual changes — omit categories where no changes were made. |
| 332 | |
| 333 | ## Notes |
| 334 | |
| 335 | - Preserve original writing style and tone |
| 336 | - Specify correct language for code blocks (e.g., `python`, `javascript`) |
| 337 | - Maintain CJK/English spacing standards |
| 338 | - The analysis file is a working document — it helps maintain consistency between what was identified and what was formatted |
| 339 | |
| 340 | ## Extension Support |
| 341 | |
| 342 | Custom configurations via EXTEND.md. See **Preferences** section for paths and supported options. |
