Parse Arguments

Extract the following from $ARGUMENTS:

1. Source text / topic: What the user wants rewritten (a sentence, a scene, a product description)
2. Style --style: The target brand aesthetic. If omitted, default to muji
3. Scene --scene: Output context. If omitted, default to slogan
   • social — Social media (Xiaohongshu / Instagram / WeChat Moments)
   • vlog — Vlog voiceover / subtitles
   • product — Product descriptions / detail pages
   • bio — Personal signature / about me
   • slogan — Tagline / headline
4. Level --level: Concentration / style intensity. If omitted, default to balanced
   • full — Full Strength: fully immersed in brand aesthetic, highest style recognition
   • balanced — Balanced: retains style essence, approachable for daily use
   • light — Light Touch: subtle hint of aesthetic, natural and effortless
   • all — Generate all three concentration levels
5. Mood --mood: Emotional direction that shapes how the copy interprets the subject. If omitted, default to neutral (no mood processing — identical to not having this parameter at all)
   • positive — Optimistic, uplifting, hopeful. Finds the bright side of the subject (e.g., rain → renewal, growth, cleansing)
   • negative — Melancholic, reflective, wistful. Leans into the somber or introspective side (e.g., rain → loneliness, longing, sadness)
   • neutral — No emotional bias. Completely transparent — skip all mood-related processing and treat input exactly as-is
6. Language --lang: Output language. When set to auto, prioritize the user's input language. Optionally append a version in the brand's native language as reference (e.g., Japanese for MUJI, French for Diptyque)

If the user provides only a sentence with no flags:

• Default style: muji
• Default scene: slogan
• Default level: balanced
• Default mood: neutral
• Default language: same as user's input
• Match the user's Chinese variant: Simplified in → Simplified out; Traditional in → Traditional out

Phase 1: Load Style Knowledge

Use the Read tool to load the corresponding style knowledge file (path relative to this skill's directory):

knowledge/styles/muji.md      — MUJI: restraint, emptiness, essence
knowledge/styles/apple.md     — Apple: minimal, confident, rhythmic
knowledge/styles/aesop.md     — Aesop: literary, sensory, intellectual
knowledge/styles/patagonia.md — Patagonia: honest, anti-consumption, activist
knowledge/styles/diptyque.md  — Diptyque: Parisian, sensory narrative, memory
knowledge/styles/snowpeak.md  — Snow Peak: nature, craftsmanship, human bonds
knowledge/styles/ikea.md      — IKEA: everyday, warm, playful
knowledge/styles/nike.md      — Nike: action, empowerment, provocation
knowledge/styles/suntory.md   — Suntory: liquid philosophy, poetic everyday
knowledge/styles/hobonichi.md — Hobonichi: gentle everyday philosophy
knowledge/styles/hermes.md    — Hermès: poetic craft, French nonchalance
knowledge/styles/rollsroyce.md — Rolls-Royce: facts as poetry, engineering elegance
knowledge/styles/guinness.md  — Guinness: patience, substance, warm storytelling

If the style name is not one of the 13 above, inform the user of available styles and ask them to choose.

Extract from the knowledge file:

• Writing principles (do's and don'ts)
• Sentence templates
• Copy density guidelines
• Classic examples as calibration benchmarks
• Never fabricate brand copy — only cite real copy from the knowledge files as examples

---

Phase 2: Analyze Source Text

Analyze the user's input for:

• Subject: What is it about? (product / scene / emotion / event)
• Emotion: What is the emotional tone? (calm / excited / moved / humorous)
• Key info: What information must be preserved?
• Imagery: Can a visual scene be distilled from it?
• Mood override (only when --mood is explicitly set to positive or negative): Reinterpret the subject through that emotional lens before generating copy. For example:
  • "下雨" + positive → associate with renewal, nourishment, fresh starts, the earth breathing
  • "下雨" + negative → associate with solitude, melancholy, longing, being trapped indoors
  • When --mood is neutral (default), skip mood processing entirely — do not reinterpret or bias the subject in any emotional direction. Treat the input exactly as-is, as if the --mood parameter does not exist

This analysis is for internal decision-making only. NEVER output this analysis to the user — not even as a labeled "internal analysis" block. Keep it completely silent. Go straight from loading style knowledge to outputting the final copy.

Scene Length Guide

Scene	Target length (Chinese)	Target length (English)
social	30-100 characters	15-50 words
vlog	50-150 characters	30-80 words
product	50-200 characters	30-100 words
bio	10-30 characters	5-15 words
slogan	4-15 characters	2-8 words

---

Phase 3: Generate Copy

Output Structure

Generate copy based on the --level parameter:

• If --level all: Generate all 3 concentration levels (Full Strength + Balanced + Light Touch)
• If --level full: Generate only the Full Strength version
• If --level balanced (default): Generate only the Balanced version
• If --level light: Generate only the Light Touch version
• Exception: If 3+ styles are selected AND level is all, output only Balanced per style to keep output concise

Full Strength (full)

Fully immersed in the brand's aesthetic world. Readers instantly recognize the style. Best for: brand official accounts, product launches, formal contexts.

Balanced (balanced)

Retains the style's essence while remaining approachable for daily use. Best for: personal social media, Vlog, everyday sharing.

Light Touch (light)

Just a hint of the aesthetic woven into natural expression. Never feels forced. Best for: WeChat Moments, casual chat, personal bio.

Each version includes:

Only the copy text itself. No style labels, concentration labels, scene suggestions, or word counts.

---

Phase 4: Style Validation

After generation, internally self-check each version against the following checklists. NEVER show the checklists, validation process, or any internal reasoning to the user. All self-checks must happen silently — do not print them. If any check fails, silently revise and re-check until all pass. NEVER output revision attempts, "Let me reconsider", "Let me refine", or any intermediate drafts to the user. If a version fails validation, discard it internally and only output the final passing version.

Phase 5: Output

Output Format

Only include the concentration level(s) matching the --level parameter. When --level all, show all three. When a single level is selected, omit the others.

[copy]

When --level all, show all three levels as sub-sections (Full Strength / Balanced / Light Touch). When a single level is selected (default), output only that level.

Do NOT include style labels, style notes, "Best for" suggestions, or word counts in the output. Just the copy itself — clean and unadorned.

Repeat the above structure for each style generated.

CRITICAL: Your entire visible output must contain ONLY the final copy inside a code block. No internal analysis, no "Internal analysis (not shown to user)" blocks, no style validation notes, no reasoning process, no "Let me reconsider/refine/revise" remarks, no intermediate drafts — absolutely nothing except the final copy itself. If you revised the copy during validation, show ONLY the final version.

Keep output minimal. Do NOT include:

• The original input (the user already knows what they wrote)
• Visual pairing suggestions
• Multilingual versions (unless the user explicitly asks via --lang)
• Hashtags (unless scene is social)

---

Special Modes

Style Comparison Mode

If the user passes --style all or explicitly asks to "rewrite in all styles", generate a 13-style comparison table:

| Style | Copy | Keywords |
|-------|------|----------|
| MUJI | ... | restraint, essence |
| Apple | ... | confidence, rhythm |
| Aesop | ... | literary, sensory |
| Patagonia | ... | honest, action |
| Diptyque | ... | sensory, memory |
| Snow Peak | ... | nature, warmth |
| IKEA | ... | everyday, humor |
| Nike | ... | action, empowerment |
| Suntory | ... | liquid philosophy, poetic |
| Hobonichi | ... | gentle, everyday |
| Hermès | ... | poetic craft, nonchalance |
| Rolls-Royce | ... | facts as poetry |
| Guinness | ... | patience, substance |

Style Mashup Mode

If the user specifies a combination like "MUJI + Apple":

1. List 3 core traits for each style
2. Find overlapping traits as primary constraints
3. For non-overlapping traits, alternate between styles (e.g., sentence structure from A, word choice from B)
4. Generate the fused version and label the "mashup ratio"

---

Iteration & Refinement

The user may request adjustments after seeing the first output. Common scenarios:

• "Make it shorter" → Increase concentration, trim to scene length minimum
• "Too literary" → Decrease concentration, or switch to a more grounded style (IKEA)
• "Mix version A and B" → Enter style mashup mode
• "Switch to English / Japanese" → Recreate in the target language (do NOT translate)
• "Add hashtags" → Generate 3-5 style-matched hashtags for the scene

---

Rules

1. Recreate, never translate: Chinese, English, and Japanese versions of the same topic should each be independently crafted, not translated from one another
2. Don't over-stylize: Especially for Light Touch — the style serves the content, not the other way around
3. Preserve core information: Rewriting is not rewriting from scratch — key info from the user's original must be retained
4. Scene dictates concentration: Social media typically suits Balanced; brand official suits Full Strength; casual chat suits Light Touch
5. Respect the source language: If the user writes in Chinese, prioritize Chinese output
6. Never fabricate brand copy: When citing examples, only use real copy from the knowledge files
7. Concentration = creative freedom: Full Strength prioritizes stylistic fidelity; Light Touch prioritizes natural readability
8. Mood shapes interpretation, not overrides content: The mood parameter guides the emotional angle of the copy but must not contradict the core subject. A positive mood on a rainy day should feel like genuine optimism, not forced cheerfulness. When mood is neutral (default), mood processing is completely skipped — output should be identical to as if --mood was never a feature
