+## Chrome Profile (Unified)
+
+All skills that use Chrome CDP share a **single** profile directory. Do NOT create per-skill profiles.
+
+| Platform | Default Path |
+|----------|-------------|
+| macOS | `~/Library/Application Support/baoyu-skills/chrome-profile` |
+| Linux | `$XDG_DATA_HOME/baoyu-skills/chrome-profile` (fallback `~/.local/share/baoyu-skills/chrome-profile`) |
+| Windows | `%APPDATA%/baoyu-skills/chrome-profile` |
+| WSL | Windows home `/.local/share/baoyu-skills/chrome-profile` |
+
+**Environment variable override**: `BAOYU_CHROME_PROFILE_DIR` (takes priority, all skills respect it).
+
+Each skill also accepts its own legacy env var as fallback (e.g., `X_BROWSER_PROFILE_DIR`), but new skills should only use `BAOYU_CHROME_PROFILE_DIR`.
+
+### Implementation Pattern
+
+When adding a new skill that needs Chrome CDP:
+
+```typescript
+function getDefaultProfileDir(): string {
+  const override = process.env.BAOYU_CHROME_PROFILE_DIR?.trim();
+  if (override) return path.resolve(override);
+  const base = process.platform === 'darwin'
+    ? path.join(os.homedir(), 'Library', 'Application Support')
+    : process.env.XDG_DATA_HOME || path.join(os.homedir(), '.local', 'share');
+  return path.join(base, 'baoyu-skills', 'chrome-profile');
+}
+```
+
+## Security Guidelines
+
+### No Piped Shell Installs
+
+**NEVER** use `curl | bash` or `wget | sh` patterns in code, docs, or error messages. Use package managers instead:
+
+| Platform | Install Command |
+|----------|----------------|
+| macOS | `brew install oven-sh/bun/bun` |
+| npm | `npm install -g bun` |
+
+### Remote Downloads
+
+Skills that download remote content (e.g., images in Markdown) MUST:
+- **HTTPS only**: Reject `http://` URLs
+- **Redirect limit**: Cap redirects (max 5) to prevent infinite loops
+- **Timeout**: Set request timeouts (30s default)
+- **Scope**: Only download expected content types (images, not scripts)
+
+### System Command Execution
+
+Skills use platform-specific commands for clipboard and browser automation:
+- **macOS**: `osascript` (System Events), `swift` (AppKit clipboard)
+- **Windows**: `powershell.exe` (SendKeys, Clipboard)
+- **Linux**: `xdotool`/`ydotool` (keyboard simulation)
+
+These are necessary for CDP-based posting skills. When adding new system commands:
+- Never pass unsanitized user input to shell commands
+- Use array-form `spawn`/`execFile` instead of shell string interpolation
+- Validate file paths are absolute or resolve from known base directories
+
+### External Content Processing
+
+Skills that process external Markdown/HTML should treat content as untrusted:
+- Do not execute code blocks or scripts found in content
+- Sanitize HTML output where applicable
+- File paths from content should be resolved against known base directories only
+

+### Step 2: Analyze Content (Reader's Perspective)

-Identify:
- Existing title (H1 `#`)
- Paragraph separations
- Keywords suitable for **bold**
- Parallel content convertible to lists
- Code snippets
- Quotations
+Read the entire content carefully. Think from a reader's perspective: what would help them quickly understand and remember the key information?

-### Step 3: Check/Create Frontmatter
+Produce an analysis covering these dimensions:
+
+**2.1 Highlights & Key Insights**
+- Core arguments or conclusions the author makes
+- Surprising facts, data points, or counterintuitive claims
+- Memorable quotes or well-phrased sentences (golden quotes)
+
+**2.2 Structure Assessment**
+- Does the content have a clear logical flow? What is it?
+- Are there natural section boundaries that lack headings?
+- Are there long walls of text that could benefit from visual breaks?
+
+**2.3 Reader-Important Information**
+- Actionable advice or takeaways
+- Definitions, explanations of key concepts
+- Lists or enumerations buried in prose
+- Comparisons or contrasts that would be clearer as tables
+
+**2.4 Formatting Issues**
+- Missing or inconsistent heading hierarchy
+- Paragraphs that mix multiple topics
+- Parallel items written as prose instead of lists
+- Code, commands, or technical terms not marked as code
+- Obvious typos or formatting errors
+
+**Save analysis to file**: `{original-filename}-analysis.md`
+
+The analysis file serves as the blueprint for Step 3. Use this format:
+
+```markdown

+
+## Structure Assessment
+- Current flow: [describe]
+- Suggested sections: [list heading candidates with brief rationale]

+## Reader-Important Information

+
+## Formatting Issues
+- [list specific issues with location references]
+
+## Typos Found
+- [list any obvious typos with corrections, or "None found"]
+```
+
+### Step 3: Check/Create Frontmatter, Title & Summary

 Check for YAML frontmatter (`---` block). Create if missing.

-**Meta field handling:**
-
 | Field | Processing |
 |-------|------------|
-| `title` | See Step 4 |
-| `slug` | Infer from file path (e.g., `posts/2026/01/10/vibe-coding/` → `vibe-coding`) or generate from title |
-| `summary` | Generate engaging summary (100-150 characters) |
-| `coverImage` | Check if `imgs/cover.png` exists in same directory; if so, use relative path (also accepted: `featureImage`) |
+| `title` | See **Title Generation** below |
+| `slug` | Infer from file path or generate from title |
+| `summary` | See **Summary Generation** below |
+| `coverImage` | Check if `imgs/cover.png` exists in same directory; if so, use relative path |

-### Step 4: Title Handling
+**Title Generation:**

-**Logic:**
-1. If frontmatter already has `title` → use it, no H1 in body
-2. If first line is H1 → extract to frontmatter `title`, remove H1 from body
-3. If neither exists → generate candidate titles
-
-**Title generation flow:**
-
-1. Generate 3 candidate titles based on content
-2. Use `AskUserQuestion` tool:
+Generate 3 candidate titles with different angles/styles. Present to user for selection:

 ```
-Select a title:
+Pick a title:

-1. [Title A] (Recommended)
-2. [Title B]
-3. [Title C]
+1. [Title A] — [angle/style note]
+2. [Title B] — [angle/style note]
+3. [Title C] — [angle/style note]
+
+Enter number, or type a custom title:
 ```

-3. If no selection within a few seconds, use recommended (option 1)
-
-**Title principles:**
- Concise, max 20 characters
- Captures core message
+Title principles:
 - Engaging, sparks reading interest
+- Captures core message or most compelling angle
 - Accurate, avoids clickbait
+- Vary angles: e.g. story-driven, conclusion-driven, question-driven

-**Important:** Once title is in frontmatter, body should NOT have H1 (avoid duplication)
+If frontmatter already has `title`, skip selection and use it. If first line is H1, extract to frontmatter as default title but still offer alternatives.

-### Step 5: Format Processing
+**Summary Generation:**

-**Formatting rules:**
+Generate 3 candidate summaries with different focuses. Present to user for selection:

-| Element | Format |
-|---------|--------|
-| Titles | Use `#`, `##`, `###` hierarchy |
-| Key points | Use `**bold**` |
-| Parallel items | Convert to `-` unordered or `1.` ordered lists |
-| Code/commands | Use `` `inline` `` or ` ```block``` ` |
-| Quotes/sayings | Use `>` blockquote |
-| Separators | Use `---` where appropriate |
+```
+Pick a summary:

-**Formatting principles:**
- Preserve original content and viewpoints
- Add formatting only, do not modify text
- Formatting serves readability
- Avoid over-formatting
+1. [Summary A] — [focus note]
+2. [Summary B] — [focus note]
+3. [Summary C] — [focus note]

-### Step 6: Save Formatted File
+Enter number, or type a custom summary:
+```
+
+Summary principles:
+- 80-150 characters, precise and information-rich
+- Convey article's core value, not just topic
+- Vary focuses: e.g. problem-driven, result-driven, insight-driven
+- Avoid generic descriptions like "本文介绍了..."
+
+If frontmatter already has `summary`, skip selection and use it.
+
+**EXTEND.md skip behavior:** If `auto_select: true` is set in EXTEND.md, skip title and summary selection — generate the best candidate directly without asking. User can also set `auto_select_title: true` or `auto_select_summary: true` independently.
+
+Once title is in frontmatter, body should NOT have H1 (avoid duplication).
+
+### Step 4: Format Content
+
+Apply formatting guided by the Step 2 analysis. The goal is making the content scannable and the key points impossible to miss.
+
+**Formatting toolkit:**
+
+| Element | When to use | Format |
+|---------|-------------|--------|
+| Headings | Natural topic boundaries, section breaks | `##`, `###` hierarchy |
+| Bold | Key conclusions, important terms, core takeaways | `**bold**` |
+| Unordered lists | Parallel items, feature lists, examples | `- item` |
+| Ordered lists | Sequential steps, ranked items, procedures | `1. item` |
+| Tables | Comparisons, structured data, option matrices | Markdown table |
+| Code | Commands, file paths, technical terms, variable names | `` `inline` `` or fenced blocks |
+| Blockquotes | Notable quotes, important warnings, cited text | `> quote` |
+| Separators | Major topic transitions | `---` |
+
+**Formatting principles — what NOT to do:**
+- Do NOT add sentences, explanations, or commentary
+- Do NOT delete or shorten any content
+- Do NOT rephrase or rewrite the author's words
+- Do NOT add headings that editorialize (e.g., "Amazing Discovery" — use neutral descriptive headings)
+- Do NOT over-format: not every sentence needs bold, not every paragraph needs a heading
+
+**Formatting principles — what TO do:**
+- Preserve the author's voice, tone, and every word
+- Use bold sparingly for genuinely important points
+- Extract parallel items from prose into lists only when the structure is clearly there
+- Add headings where the topic genuinely shifts
+- Fix obvious typos (based on Step 2 findings)
+
+### Step 5: Save Formatted File

 Save as `{original-filename}-formatted.md`

-Examples:
- `final.md` → `final-formatted.md`
- `draft-v1.md` → `draft-v1-formatted.md`
-
-**If user chose "Keep original formatting" (from Step 1.5):**
- Copy original file to `{filename}-formatted.md` without modifications
- Proceed to Step 7 for typography fixes only
-
 **Backup existing file:**

-If `{filename}-formatted.md` already exists, backup before overwriting:
-
 ```bash
-# Check if formatted file exists
 if [ -f "{filename}-formatted.md" ]; then
-  # Backup with timestamp
  mv "{filename}-formatted.md" "{filename}-formatted.backup-$(date +%Y%m%d-%H%M%S).md"
 fi
 ```

-Example:
- `final-formatted.md` exists → backup to `final-formatted.backup-20260128-143052.md`

-### Step 7: Execute Text Formatting Script

+## Script Directory
+
+**Important**: All scripts are located in the `scripts/` subdirectory of this skill.
+
+**Agent Execution Instructions**:
+1. Determine this SKILL.md file's directory path as `SKILL_DIR`
+2. Script path = `${SKILL_DIR}/scripts/<script-name>.ts`
+3. Replace all `${SKILL_DIR}` in this document with the actual path
+4. Resolve `${BUN_X}` runtime: if `bun` installed → `bun`; if `npx` available → `npx -y bun`; else suggest installing bun
+
+**Script Reference**:
+| Script | Purpose |
+|--------|---------|
+| `scripts/weibo-post.ts` | Regular posts (text + images) |
+| `scripts/weibo-article.ts` | Headline article publishing (Markdown) |
+| `scripts/copy-to-clipboard.ts` | Copy content to clipboard |

+**EXTEND.md Supports**: Default Chrome profile
+
+## Prerequisites
+
+- Google Chrome or Chromium
+- `bun` runtime
+- First run: log in to Weibo manually (session saved)
+
+---
+
+## Regular Posts
+
+Text + up to 9 images. Posted on Weibo homepage.
+
+```bash
+${BUN_X} ${SKILL_DIR}/scripts/weibo-post.ts "Hello Weibo!" --image ./photo.png
+```
+
+**Parameters**:
+| Parameter | Description |
+|-----------|-------------|
+| `<text>` | Post content (positional) |
+| `--image <path>` | Image file (repeatable, max 9) |
+| `--profile <dir>` | Custom Chrome profile |
+
+**Note**: Script opens browser with content filled in. User reviews and publishes manually.
+
+---
+
+## Headline Articles (头条文章)
+
+Long-form Markdown articles published at `https://card.weibo.com/article/v3/editor`.
+
+```bash
+${BUN_X} ${SKILL_DIR}/scripts/weibo-article.ts article.md
+${BUN_X} ${SKILL_DIR}/scripts/weibo-article.ts article.md --cover ./cover.jpg
+```
+
+**Parameters**:
+| Parameter | Description |
+|-----------|-------------|
+| `<markdown>` | Markdown file (positional) |
+| `--cover <path>` | Cover image |
+| `--title <text>` | Override title (max 32 chars, truncated if longer) |
+| `--summary <text>` | Override summary (max 44 chars, auto-regenerated if longer) |
+| `--profile <dir>` | Custom Chrome profile |
+
+**Frontmatter**: `title`, `summary`, `cover_image` supported in YAML front matter.
+
+**Character Limits**:
+- Title: 32 characters max (truncated with warning if longer)
+- Summary/导语: 44 characters max (auto-regenerated from content if longer)
+
+**Article Workflow**:
+1. Opens `https://card.weibo.com/article/v3/editor`
+2. Clicks "写文章" button, waits for editor to become editable
+3. Fills title (validated for 32-char limit)
+4. Fills summary/导语 (validated for 44-char limit)
+5. Inserts HTML content into ProseMirror editor via paste
+6. Replaces image placeholders one by one (copy image → select placeholder → paste)
+
+**Post-Composition Check**: The script automatically verifies after all images are inserted:
+- Remaining `WBIMGPH_` placeholders in editor content
+- Expected vs actual image count
+
+If the check fails (warnings in output), alert the user with the specific issues before they publish.
+
+---
+
+## Troubleshooting
+
+### Chrome debug port not ready
+
+If a script fails with `Chrome debug port not ready` or `Unable to connect`, kill existing Chrome CDP instances first, then retry:
+
+```bash
+pkill -f "Chrome.*remote-debugging-port" 2>/dev/null; pkill -f "Chromium.*remote-debugging-port" 2>/dev/null; sleep 2
+```
+
+**Important**: This should be done automatically -- when encountering this error, kill Chrome CDP instances and retry the command without asking the user.
+
+## Notes
+
+- First run: manual login required (session persists)
+- All scripts only fill content into the browser, user must review and publish manually
+- Cross-platform: macOS, Linux, Windows

+description: Translates articles and documents between languages with three modes - quick (direct), normal (analyze then translate), and refined (analyze, translate, review, polish). Supports custom glossaries and terminology consistency via EXTEND.md. Use when user asks to "translate", "翻译", "精翻", "translate article", "translate to Chinese/English", "改成中文", "改成英文", "convert to Chinese", "localize", "本地化", or needs any document translation. Also triggers for "refined translation", "精细翻译", "proofread translation", "快速翻译", "快翻", "这篇文章翻译一下", or when a URL or file is provided with translation intent.
+---
+
+# Translator
+
+Three-mode translation skill: **quick** for direct translation, **normal** for analysis-informed translation, **refined** for full publication-quality workflow with review and polish.
+
+## Script Directory
+
+Scripts in `scripts/` subdirectory. `${SKILL_DIR}` = this SKILL.md's directory path. Resolve `${BUN_X}` runtime: if `bun` installed → `bun`; if `npx` available → `npx -y bun`; else suggest installing bun. Replace `${SKILL_DIR}` and `${BUN_X}` with actual values.
+
+| Script | Purpose |
+|--------|---------|
+| `scripts/chunk.ts` | Split markdown into chunks by AST blocks (sections, headings, paragraphs), with line/word fallback for oversized blocks. Use `--output-dir <dir>` to write chunks into `<dir>/chunks/` instead of `<source-dir>/chunks/` |

+
+| Result | Action |
+|--------|--------|
+| Found | Read, parse, apply settings. On first use in session, briefly remind: "Using preferences from [path]. You can edit EXTEND.md to customize glossary, audience, etc." |
+| Not found | **MUST** run first-time setup (see below) — do NOT silently use defaults |
+
+**EXTEND.md Supports**: Default target language | Default mode | Target audience | Custom glossaries | Translation style | Chunk settings
+
+Schema: [references/config/extend-schema.md](references/config/extend-schema.md)
+
+### First-Time Setup (BLOCKING)
+
+**CRITICAL**: When EXTEND.md is not found, you **MUST** run the first-time setup before ANY translation. This is a **BLOCKING** operation.
+
+Full reference: [references/config/first-time-setup.md](references/config/first-time-setup.md)
+
+Use `AskUserQuestion` with all questions (target language, mode, audience, style, save location) in ONE call. After user answers, create EXTEND.md at the chosen location, confirm "Preferences saved to [path]", then continue.
+
+## Defaults
+
+All configurable values in one place. EXTEND.md overrides these; CLI flags override EXTEND.md.
+
+| Setting | Default | EXTEND.md key | CLI flag | Description |
+|---------|---------|---------------|----------|-------------|
+| Target language | `zh-CN` | `target_language` | `--to` | Translation target language |
+| Mode | `normal` | `default_mode` | `--mode` | Translation mode |
+| Audience | `general` | `audience` | `--audience` | Target reader profile |
+| Style | `storytelling` | `style` | `--style` | Translation style preference |
+| Chunk threshold | `4000` | `chunk_threshold` | — | Word count to trigger chunked translation |
+| Chunk max words | `5000` | `chunk_max_words` | — | Max words per chunk |
+
+## Modes
+
+| Mode | Flag | Steps | When to Use |
+|------|------|-------|-------------|
+| Quick | `--mode quick` | Translate | Short texts, informal content, quick tasks |
+| Normal | `--mode normal` (default) | Analyze → Translate | Articles, blog posts, general content |
+| Refined | `--mode refined` | Analyze → Translate → Review → Polish | Publication-quality, important documents |
+
+**Default mode**: Normal (can be overridden in EXTEND.md `default_mode` setting).
+
+**Style presets** — control the voice and tone of the translation (independent of audience):
+
+| Value | Description | Effect |
+|-------|-------------|--------|
+| `storytelling` | Engaging narrative flow (default) | Draws readers in, smooth transitions, vivid phrasing |
+| `formal` | Professional, structured | Neutral tone, clear organization, no colloquialisms |
+| `technical` | Precise, documentation-style | Concise, terminology-heavy, minimal embellishment |
+| `literal` | Close to original structure | Minimal restructuring, preserves source sentence patterns |
+| `academic` | Scholarly, rigorous | Formal register, complex clauses OK, citation-aware |
+| `business` | Concise, results-focused | Action-oriented, executive-friendly, bullet-point mindset |
+| `humorous` | Preserves and adapts humor | Witty, playful, recreates comedic effect in target language |
+| `conversational` | Casual, spoken-like | Friendly, approachable, as if explaining to a friend |
+| `elegant` | Literary, polished prose | Aesthetically refined, rhythmic, carefully crafted word choices |
+
+Custom style descriptions are also accepted, e.g., `--style "poetic and lyrical"`.
+
+**Auto-detection**:
+- "快翻", "quick", "直接翻译" → quick mode
+- "精翻", "refined", "publication quality", "proofread" → refined mode
+- Otherwise → default mode (normal)
+
+**Upgrade prompt**: After normal mode completes, display:
+> Translation saved. To further review and polish, reply "继续润色" or "refine".
+
+If user responds, continue with review → polish steps (same as refined mode Steps 4-6 in refined-workflow.md) on the existing output.
+
+## Usage
+
+```
+/translate [--mode quick|normal|refined] [--from <lang>] [--to <lang>] [--audience <audience>] [--style <style>] [--glossary <file>] <source>
+```
+
+- `<source>`: File path, URL, or inline text
+- `--from`: Source language (auto-detect if omitted)
+- `--to`: Target language (from EXTEND.md or default `zh-CN`)
+- `--audience`: Target reader profile (from EXTEND.md or default `general`)
+- `--style`: Translation style (from EXTEND.md or default `storytelling`)
+- `--glossary`: Additional glossary file to merge with EXTEND.md glossary
+
+**Audience presets**:
+
+| Value | Description | Effect |
+|-------|-------------|--------|
+| `general` | General readers (default) | Plain language, more translator's notes for jargon |
+| `technical` | Developers / engineers | Less annotation on common tech terms |
+| `academic` | Researchers / scholars | Formal register, precise terminology |
+| `business` | Business professionals | Business-friendly tone, explain tech concepts |
+
+Custom audience descriptions are also accepted, e.g., `--audience "AI感兴趣的普通读者"`.
+
+## Workflow
+
+### Step 1: Load Preferences
+
+1.1 Check EXTEND.md (see Preferences section above)
+
+1.2 Load built-in glossary for the language pair if available:
+- EN→ZH: [references/glossary-en-zh.md](references/glossary-en-zh.md)
+
+1.3 Merge glossaries: EXTEND.md glossary + built-in glossary + `--glossary` file (CLI overrides all)
+
+### Step 2: Materialize Source & Create Output Directory
+
+Materialize source (file as-is, inline text/URL → save to `translate/{slug}.md`), then create output directory: `{source-dir}/{source-basename}-{target-lang}/`. Detect source language if `--from` not specified.
+
+Full details: [references/workflow-mechanics.md](references/workflow-mechanics.md)
+
+**Output directory contents** (all intermediate and final files go here):
+
+| File | Mode | Description |
+|------|------|-------------|
+| `translation.md` | All | Final translation (always this name) |
+| `01-analysis.md` | Normal, Refined | Content analysis (domain, tone, terminology) |
+| `02-prompt.md` | Normal, Refined | Assembled translation prompt |
+| `03-draft.md` | Refined | Initial draft before review |
+| `04-critique.md` | Refined | Critical review findings (diagnosis only) |
+| `05-revision.md` | Refined | Revised translation based on critique |
+| `chunks/` | Chunked | Source chunks + translated chunks |
+
+### Step 3: Assess Content Length
+
+Quick mode does not chunk — translate directly regardless of length. Before translating, estimate word count. If content exceeds chunk threshold (default 4000 words), proactively warn: "This article is ~{N} words. Quick mode translates in one pass without chunking — for long content, `--mode normal` produces better results with terminology consistency." Then proceed if user doesn't switch.
+
+For normal and refined modes:
+
+| Content | Action |
+|---------|--------|
+| < chunk threshold | Translate as single unit |
+| >= chunk threshold | Chunk translation (see Step 3.1) |
+
+**3.1 Long Content Preparation** (normal/refined modes, >= chunk threshold only)
+
+Before translating chunks:
+
+1. **Extract terminology**: Scan entire document for proper nouns, technical terms, recurring phrases
+2. **Build session glossary**: Merge extracted terms with loaded glossaries, establish consistent translations
+3. **Split into chunks**: Use `${BUN_X} ${SKILL_DIR}/scripts/chunk.ts <file> [--max-words <chunk_max_words>] [--output-dir <output-dir>]`
+   - Parses markdown AST (headings, paragraphs, lists, code blocks, tables, etc.)
+   - Splits at markdown block boundaries to preserve structure
+   - If a single block exceeds the threshold, falls back to line splitting, then word splitting
+4. **Assemble translation prompt**:
+   - Main agent reads `01-analysis.md` (if exists) and assembles shared context using Part 1 of [references/subagent-prompt-template.md](references/subagent-prompt-template.md) — inlining content background, merged glossary, and comprehension challenges
+   - Save as `02-prompt.md` in the output directory (shared context only, no task instructions)
+5. **Draft translation via subagents** (if Agent tool available):
+   - Spawn one subagent **per chunk**, all in parallel (Part 2 of the template)
+   - Each subagent reads `02-prompt.md` for shared context, translates its chunk, saves to `chunks/chunk-NN-draft.md`
+   - Terminology consistency is guaranteed by the shared `02-prompt.md` (glossary + comprehension challenges from analysis)
+   - If no chunks (content under threshold): spawn one subagent for the entire source file
+   - If Agent tool is unavailable, translate chunks sequentially inline using `02-prompt.md`
+6. **Merge**: Once all subagents complete, combine translated chunks in order. If `chunks/frontmatter.md` exists, prepend it. Save as `03-draft.md` (refined) or `translation.md` (normal)
+7. All intermediate files (source chunks + translated chunks) are preserved in `chunks/`
+
+**After chunked draft is merged**, return control to main agent for critical review, revision, and polish (Step 4).
+
+### Step 4: Translate & Refine
+
+**Translation principles** (apply to all modes):
+
+- **Accuracy first**: Facts, data, and logic must match the original exactly
+- **Meaning over words**: Translate what the author means, not just what the words say. When a literal translation sounds unnatural or fails to convey the intended effect, restructure freely to express the same meaning in idiomatic target language
+- **Figurative language**: Interpret metaphors, idioms, and figurative expressions by their intended meaning rather than translating them word-for-word. When a source-language image does not carry the same connotation in the target language, replace it with a natural expression that conveys the same idea and emotional effect
+- **Emotional fidelity**: Preserve the emotional connotations of word choices, not just their dictionary meanings. Words that carry subjective feelings (e.g., "alarming", "haunting") should be rendered to evoke the same response in target-language readers
+- **Natural flow**: Use idiomatic target language word order and sentence patterns; break or restructure sentences freely when the source structure doesn't work naturally in the target language
+- **Terminology**: Use standard translations; annotate with original term in parentheses on first occurrence
+- **Preserve format**: Keep all markdown formatting (headings, bold, italic, images, links, code blocks)
+- **Respect original**: Maintain original meaning and intent; do not add, remove, or editorialize — but sentence structure and imagery may be adapted freely to serve the meaning
+- **Translator's notes**: For terms, concepts, or cultural references that target readers may not understand — due to jargon, cultural gaps, or domain-specific knowledge — add a concise explanatory note in parentheses immediately after the term. The note should explain *what it means* in plain language, not just provide the English original. Format: `译文（English original，通俗解释）`. Calibrate annotation depth to the target audience: general readers need more notes than technical readers. Only add notes where genuinely needed; do not over-annotate obvious terms.
+
+#### Quick Mode
+
+Translate directly → save to `translation.md`. No analysis file, but still apply all translation principles above — especially: interpret figurative language by meaning (not word-for-word), preserve emotional connotations, and restructure sentences for natural target-language flow.
+
+#### Normal Mode
+
+1. **Analyze** → `01-analysis.md` (domain, tone, audience, terminology, reader comprehension challenges, figurative language & metaphor mapping)
+2. **Assemble prompt** → `02-prompt.md` (translation instructions with inlined context)
+3. **Translate** (following `02-prompt.md`) → `translation.md`
+
+After completion, prompt user: "Translation saved. To further review and polish, reply **继续润色** or **refine**."
+
+If user continues, proceed with critical review → revision → polish (same as refined mode Steps 4-6 below), saving `03-draft.md` (rename current `translation.md`), `04-critique.md`, `05-revision.md`, and updated `translation.md`.
+
+#### Refined Mode
+
+Full workflow for publication quality. See [references/refined-workflow.md](references/refined-workflow.md) for detailed guidelines per step.
+
+The subagent (if used in Step 3.1) only handles the initial draft. All subsequent steps (critical review, revision, polish) are handled by the main agent, which may delegate to subagents at its discretion.
+
+Steps and saved files (all in output directory):
+1. **Analyze** → `01-analysis.md` (domain, tone, terminology, reader comprehension challenges, figurative language & metaphor mapping)
+2. **Assemble prompt** → `02-prompt.md` (translation instructions with inlined context)
+3. **Draft** → `03-draft.md` (initial translation with translator's notes; from subagent if chunked)
+4. **Critical review** → `04-critique.md` (diagnosis only: accuracy, Europeanized language, strategy execution, expression issues)
+5. **Revision** → `05-revision.md` (apply all critique findings to produce revised translation)
+6. **Polish** → `translation.md` (final publication-quality translation)
+
+Each step reads the previous step's file and builds on it.
+
+### Step 5: Output
+
+Final translation is always at `translation.md` in the output directory.
+
+Display summary:
+```

+# Translation Workflow Details
+
+This file provides detailed guidelines for each workflow step. Steps are shared across modes:
+
+- **Quick**: Translate only (no steps from this file)
+- **Normal**: Step 1 (Analysis) → Translate
+- **Refined**: Step 1 (Analysis) → Step 2 (Draft) → Step 3 (Review) → Step 4 (Revision) → Step 5 (Polish)
+- **Normal → Upgrade**: After normal mode, user can continue with Step 3 → Step 4 → Step 5
+
+All intermediate results are saved as files in the output directory.
+
+## Step 1: Content Analysis
+
+Before translating, deeply analyze the source material. Save analysis to `01-analysis.md` in the output directory. Focus on dimensions that directly inform translation quality.
+
+### 1.1 Quick Summary
+
+3-5 sentences capturing:
+- What is this content about?
+- What is the core argument?
+- What is the most valuable point?
+
+### 1.2 Core Content
+
+- **Core argument**: One sentence summary
+- **Key concepts**: What key concepts does the author use? How are they defined?
+- **Structure**: How is the argument developed? How do sections connect?
+- **Evidence**: What specific examples, data, or authoritative citations are used?
+
+### 1.3 Background Context
+
+- **Author**: Who is the author? What is their background and stance?
+- **Writing context**: What phenomenon, trend, or debate is this responding to?
+- **Purpose**: What problem is the author trying to solve? Who are they trying to influence?
+- **Implicit assumptions**: What unstated premises underlie the argument?
+
+### 1.4 Terminology Extraction
+
+- List all technical terms, proper nouns, brand names, acronyms
+- Cross-reference with loaded glossaries
+- For terms not in glossary, research standard translations
+- Record decisions in a working terminology table
+
+### 1.5 Tone & Style
+
+- Is the original formal or conversational?
+- Does it use humor, metaphor, or cultural references?
+- What register is appropriate for the translation given the target audience?
+
+### 1.6 Reader Comprehension Challenges
+
+Identify points where target readers may struggle, calibrated to the target audience:
+
+- **Domain jargon**: Technical terms that lack widely-known translations or are meaningless when translated literally
+- **Cultural references**: Idioms, historical events, pop culture, social norms specific to the source culture
+- **Implicit knowledge**: Background context the original author assumes but target readers may lack
+- **Wordplay & metaphors**: Figurative language that doesn't carry over across languages
+- **Named concepts**: Theories, effects, or phenomena with coined names (e.g., "comb-over effect", "Dunning-Kruger effect")
+- **Cognitive gaps**: Counterintuitive claims or expectations vs. reality that need framing for target readers
+
+For each identified challenge, note:
+1. The original term/passage
+2. Why it may confuse target readers
+3. A concise plain-language explanation to use as a translator's note
+
+### 1.7 Figurative Language & Metaphor Mapping
+
+Identify all metaphors, similes, idioms, and figurative expressions in the source. For each:
+
+1. **Original expression**: The exact phrase
+2. **Intended meaning**: What the author is actually communicating (the idea behind the image)
+3. **Literal translation risk**: Would a word-for-word translation sound unnatural, lose the connotation, or confuse target readers?
+4. **Target-language approach**: One of:
+   - **Interpret**: Discard the source image entirely, express the intended meaning directly in natural target language
+   - **Substitute**: Replace with a target-language idiom or image that conveys the same idea and emotional effect
+   - **Retain**: Keep the original image if it works equally well in the target language
+
+Also flag:
+- **Emotional connotations carried by word choice**: Words like "alarming" that convey subjective feeling, not just objective description — note the emotional effect to preserve
+- **Implied meanings**: Sentences where the surface meaning is simple but the implication is richer — note what the author really means so the translator can convey the full intent
+
+### 1.8 Structural & Creative Challenges
+
+- Complex sentence patterns (long subordinate clauses, nested modifiers, participial phrases) that need restructuring for natural target-language flow
+- Structural challenges (wordplay, ambiguity, puns that don't translate)
+- Content where the author's voice or humor requires creative adaptation
+
+**Save `01-analysis.md`** with:
+```
+## Quick Summary
+[3-5 sentences]
+
+## Core Content
+Core argument: [one sentence]
+Key concepts: [list]
+Structure: [outline]
+
+## Background Context
+Author: [who, background, stance]
+Writing context: [what this responds to]
+Purpose: [goal and target audience]
+Implicit assumptions: [unstated premises]

+## Terminology

+## Tone & Style

+## Comprehension Challenges

+## Figurative Language & Metaphor Mapping
+- [original expression] → [intended meaning] → [approach: interpret/substitute/retain] → [suggested rendering]
+- ...
+
+## Structural & Creative Challenges
+[sentence restructuring needs, wordplay, creative adaptation needs]
+```
+
+## Step 2: Assemble Translation Prompt
+
+Main agent reads `01-analysis.md` and assembles a complete translation prompt using [references/subagent-prompt-template.md](subagent-prompt-template.md). Inline content background, merged glossary, and comprehension challenges into the prompt. Save to `02-prompt.md`.
+
+This prompt is used by the subagent (chunked) or by the main agent itself (non-chunked).
+
+## Step 3: Initial Draft
+
+Save to `03-draft.md` in the output directory.
+
+For chunked content, the subagent produces this draft (merged from chunk translations). For non-chunked content, the main agent produces it directly.
+
+Translate the full content following `02-prompt.md`. Apply all **Translation principles** from SKILL.md Step 4, plus these step-specific guidelines:
+
+- Use the terminology decisions from Step 1 consistently
+- Match the identified tone and register
+- Follow the metaphor mapping from Step 1 for figurative language handling
+- Add translator's notes for comprehension challenges identified in Step 1
+
+## Step 4: Critical Review
+
+The main agent critically reviews the draft against the source. Save review findings to `04-critique.md`. This step produces **diagnosis only** — no rewriting yet.
+
+### 4.1 Accuracy & Completeness
+- Compare each paragraph against the original, sentence by sentence
+- Verify all facts, numbers, dates, and proper nouns
+- Flag any content accidentally added, removed, or altered
+- Check that technical terms match glossary consistently throughout
+- Verify no paragraphs or sections were skipped
+
+### 4.2 Europeanized Language Diagnosis (for CJK targets)
+- **Unnecessary connectives**: Overuse of 因此/然而/此外/另外 where context already implies the relationship
+- **Passive voice abuse**: Excessive 被/由/受到 where active voice is more natural
+- **Noun pile-up**: Long modifier chains that should be broken into shorter clauses
+- **Cleft sentences**: Unnatural "是...的" structures calqued from English "It is...that"
+- **Over-nominalization**: Abstract nouns where verbs or adjectives would be more natural (e.g., "进行了讨论" → "讨论了")
+- **Awkward pronouns**: Overuse of 他/她/它/我们/你 where they can be omitted
+
+### 4.3 Figurative Language & Emotional Fidelity
+- Cross-check against the metaphor mapping in `01-analysis.md`: were all flagged metaphors/idioms handled per the recommended approach (interpret/substitute/retain)?
+- Flag any metaphors or figurative expressions that were translated literally and sound unnatural or lose the intended meaning in the target language
+- Check emotional connotations: do words that carry subjective feelings in the source (e.g., "alarming", "haunting", "striking") evoke the same response in the translation, or were they flattened into neutral/objective descriptions?
+- Flag implied meanings that were lost: sentences where the author's deeper intent was not conveyed because the translator stayed too close to the surface meaning
+
+### 4.4 Strategy Execution
+- Were the translation strategies from `02-prompt.md` actually followed?
+- Did the translator apply the tone and register identified in analysis?
+- Were comprehension challenges from `01-analysis.md` addressed with appropriate notes?
+- Were glossary terms used consistently?
+
+### 4.5 Expression & Logic
+- Flag sentences that read like "translationese" — unnatural word order, calques, stiff phrasing
+- Check logical flow between sentences and paragraphs
+- Identify where sentence restructuring would improve readability
+- Note where the target language idiom was missed
+
+### 4.6 Translator's Notes Quality
+- Are notes accurate, concise, and genuinely helpful?
+- Identify missed comprehension challenges that need notes
+- Flag over-annotations on terms obvious to the target audience
+- Check that cultural references are explained where needed
+
+### 4.7 Cultural Adaptation
+- Do metaphors and idioms work in the target language?
+- Are any references potentially confusing or offensive in the target culture?
+- Could any passage be misinterpreted due to cultural context differences?
+
+**Save `04-critique.md`** with:
+```
+## Accuracy & Completeness
+- [issue]: [location] — [description]
+- ...
+
+## Europeanized Language Issues
+- [issue type]: [example from draft] → [suggested fix]
+- ...
+
+## Figurative Language & Emotional Fidelity
+- [literal metaphor]: [original] → [draft rendering] → [suggested interpretation]
+- [flattened emotion]: [original word/phrase] → [draft rendering] → [how to restore emotional effect]
+- ...
+
+## Strategy Execution
+- [strategy]: [followed/missed] — [details]
+- ...
+
+## Expression & Logic
+- [location]: [problem] → [suggestion]
+- ...
+
+## Translator's Notes
+- [add/remove/revise]: [term] — [reason]
+- ...
+
+## Cultural Adaptation
+- [issue]: [description] — [suggestion]
+- ...
+
+## Summary
+[Overall assessment: X critical issues, Y improvements, Z minor suggestions]
+```
+
+## Step 5: Revision
+
+Apply all findings from `04-critique.md` to produce a revised translation. Save to `05-revision.md`.
+
+The revision reads `03-draft.md` (the original draft) and `04-critique.md` (the review findings), and may also refer back to the source text and `01-analysis.md`:
+
+- Fix all accuracy issues identified in the critique
+- Rewrite Europeanized expressions into natural target-language patterns
+- Re-interpret literally translated metaphors and figurative expressions per the metaphor mapping; replace with natural target-language renderings that convey the intended meaning and emotional effect
+- Restore flattened emotional connotations: ensure words carrying subjective feelings evoke the same response as the source
+- Apply missed translation strategies
+- Restructure stiff or awkward sentences for fluency
+- Add, remove, or revise translator's notes per critique recommendations
+- Improve transitions between paragraphs
+- Adapt cultural references as suggested
+
+## Step 6: Polish
+
+Save final version to `translation.md`.
+
+Final pass on `05-revision.md` for publication quality:
+
+- Read the entire translation as a standalone piece — does it flow as native content?
+- Smooth any remaining rough transitions between paragraphs
+- Ensure the narrative voice is consistent throughout
+- Apply the selected translation style consistently: storytelling should flow like a narrative, formal should maintain neutral professionalism, humorous should land jokes naturally in the target language, etc.
+- Final scan for surviving literal metaphors or flattened emotions: any figurative expression that still reads as "translated" rather than "written" should be recast into natural target-language expression
+- Final consistency check on terminology across the full text
+- Verify formatting is preserved correctly (headings, bold, links, code blocks)
+- Remove any remaining traces of translationese
+
+## Subagent Responsibility
+
+Each subagent (one per chunk) is responsible **only** for producing the initial draft of its chunk (Step 3). The main agent assembles the shared prompt (Step 2), spawns all subagents in parallel, then takes over for critical review (Step 4), revision (Step 5), and polish (Step 6). The main agent may delegate revision or polish to subagents at its own discretion.
+
+## Chunked Refined Translation
+
+When content exceeds the chunk threshold (see Defaults in SKILL.md) and uses refined mode:
+
+1. Main agent runs analysis (Step 1) on the **entire** document first → `01-analysis.md`
+2. Main agent assembles translation prompt → `02-prompt.md`
+3. Split into chunks → `chunks/`
+4. Spawn one subagent per chunk in parallel (each reads `02-prompt.md` for shared context) → merge all results into `03-draft.md`
+5. Main agent critically reviews the merged draft → `04-critique.md`
+6. Main agent revises based on critique → `05-revision.md`
+7. Main agent polishes → `translation.md`
+7. Final cross-chunk consistency check:
+   - Check terminology consistency across chunk boundaries
+   - Verify narrative flow between chunks
+   - Fix any transition issues at chunk boundaries

+

+You are a professional translator. Your task is to translate markdown content from {source_lang} to {target_lang}.
+
+## Target Audience
+
+{audience description}
+
+## Translation Style
+
+{style description — e.g., "storytelling: engaging narrative flow, smooth transitions, vivid phrasing" or custom style from user}
+
+Apply this style consistently: it determines the voice, tone, and sentence-level choices throughout the translation. Style is independent of audience — a technical audience can still get a storytelling-style translation, or a general audience can get a formal one.
+
+## Content Background
+
+{Inlined from 01-analysis.md if analysis exists: quick summary, core argument, author background, writing context, tone assessment, figurative language & metaphor mapping.}
+
+## Glossary
+
+Apply these term translations consistently throughout. First occurrence of each term: include the original in parentheses after the translation.
+
+{Merged glossary — combine built-in glossary + EXTEND.md glossary + terms extracted in analysis. One per line: English → Translation}

+## Comprehension Challenges
+
+The following terms or references may confuse target readers. Add translator's notes in parentheses where they appear: `译文（English original，通俗解释）`
+
+{Inlined from 01-analysis.md comprehension challenges section if analysis exists. Each entry: term → explanation to use as note.}
+
+## Translation Principles
+
+- **Accuracy first**: Facts, data, and logic must match the original exactly
+- **Meaning over words**: Translate what the author means, not just what the words say. When a literal translation sounds unnatural or fails to convey the intended effect, restructure freely to express the same meaning in idiomatic {target_lang}
+- **Figurative language**: Interpret metaphors, idioms, and figurative expressions by their intended meaning. When a source-language image does not carry the same connotation in {target_lang}, replace it with a natural expression that conveys the same idea and emotional effect. Refer to the Figurative Language section in Content Background (if provided) for pre-analyzed metaphor mappings
+- **Emotional fidelity**: Preserve the emotional connotations of word choices, not just their dictionary meanings
+- **Natural flow**: Use idiomatic {target_lang} word order and sentence patterns; break or restructure sentences freely when the source structure doesn't work naturally
+- **Terminology**: Use glossary translations consistently; annotate with original term in parentheses on first occurrence
+- **Preserve format**: Keep all markdown formatting (headings, bold, italic, images, links, code blocks)
+- **Respect original**: Maintain original meaning and intent; do not add, remove, or editorialize — but sentence structure and imagery may be adapted freely to serve the meaning
+- **Translator's notes**: For terms or cultural references listed in Comprehension Challenges above, add a concise explanatory note in parentheses. Only annotate where genuinely needed for the target audience.

+
+Examples:
+- `posts/article.md` → `posts/article-zh/`
+- `translate/ai-future.md` → `translate/ai-future-zh/`
+
+## Conflict Resolution
+
+If the output directory already exists, rename the existing one to `{name}.backup-YYYYMMDD-HHMMSS/` before creating the new one. Never overwrite existing results.
