Cross-Platform Adapter — One Source, Five Platforms

Take any long-form content (blog post, report, speech, internal doc, newsletter) and produce tailored versions for LinkedIn, Twitter/X, WeChat Official Accounts, Zhihu, and Slack. Each version respects the platform's character limits, audience expectations, formatting conventions, and cultural context.

When to Use

• User has a piece of content and wants to distribute it across multiple platforms
• User asks to "repurpose this," "adapt this for LinkedIn/Twitter/WeChat/Zhihu/Slack," or "make platform versions"
• User wants to maximize reach from a single content investment

Input

The user provides source content (article, blog post, report, talking points, etc.) and optionally specifies:

• Target platforms (default: all five)
• Target audience per platform (if different from general)
• Language preference per platform (Chinese for WeChat/Zhihu, English for LinkedIn/Twitter/Slack — or user-specified)
• Tone override (e.g., "keep LinkedIn more casual than usual")
• Specific CTA per platform

SOP — Step-by-Step Process

Length scaling: The per-platform character recommendations below assume a medium-length source (~500–1,500 words). For shorter sources, scale down proportionally — a 300-word blog post should NOT be padded to hit 1,500 Chinese characters on WeChat. Quality over length.

Step 1: Analyze the Source Content

Read the full input and extract:

1. Core message — the single main idea in one sentence
2. Key supporting points — 3–7 distinct arguments, data points, or stories
3. Target audience — who benefits from this content
4. Content type — educational, opinion, announcement, case study, how-to, thought leadership
5. Quotable moments — short, punchy phrases that can stand alone
6. Data and evidence — statistics, research citations, concrete examples
7. Original language — note whether the source is in English, Chinese, or mixed

Step 2: Platform Analysis Matrix

Before writing, map each platform's constraints:

Step 3: Produce LinkedIn Version

Constraints:

• Length: 1,200–1,800 characters recommended (posts under 1,300 chars get the "see more" fold at ~210 chars)
• Language: English by default; Chinese if user specifies or source is Chinese
• No markdown rendering — use Unicode line breaks and emoji sparingly for structure

Structure:

1. Hook line (first 210 characters — visible before "see more"): Start with a bold or surprising statement. This must compel the click.
2. Body (3–5 short paragraphs): One idea per paragraph. Use single-line breaks between paragraphs for visual breathing room. Include 1–2 data points from the source.
3. Personal insight (1–2 sentences): Add a "here's what I've learned" or "my take" element — LinkedIn rewards personal perspective.
4. CTA (final line): One clear ask — comment, share, or follow.

LinkedIn-specific rules:

• No hashtags in the first line — they look spammy
• 3–5 hashtags at the very end, if used at all
• Avoid corporate jargon ("synergy," "leverage," "disruption") unless the source specifically uses it
• Short sentences. Single-sentence paragraphs are fine and perform well.
• Do not fabricate personal anecdotes — only include what the source provides

Step 4: Produce Twitter/X Version

Constraints:

• Hard limit: 280 characters per tweet
• Thread length: 5–15 tweets ideal
• Language: English by default

Structure:

1. Hook tweet: Use a proven pattern — contrarian claim, surprising stat, bold promise, or relatable pain point. End with a thread indicator (e.g., "A thread:"). No hashtags in tweet 1.
2. Body tweets: One idea per tweet. Use line breaks for readability within tweets. Maintain logical flow — each tweet builds on the previous.
3. CTA tweet: Drive exactly one action (follow, reply, repost, bookmark).

Twitter-specific rules:

• Count characters carefully — URLs count as 23 characters, emojis as 2
• Include tweet numbering (2/, 3/, etc.) for threads over 5 tweets; hook tweet does not get a number
• Short punchy tweets (under 100 chars) between dense tweets for rhythm
• Preserve all statistics and facts from source — never fabricate
• Show character count for each tweet in the output

Step 5: Produce WeChat Official Accounts Version

Constraints:

• Length: 1,500–3,000 Chinese characters recommended for readability
• Language: Chinese (translate from English source if needed; preserve original meaning, do not transliterate)
• Rich formatting supported: headers, bold, blockquotes, section dividers

Structure:

1. Title: 15–30 Chinese characters. Must spark curiosity or promise value. Avoid clickbait that doesn't deliver.
2. Opening paragraph: 2–3 sentences establishing why the reader should care. Use a relatable scenario, surprising data point, or question.
3. Body: Organize into 3–5 sections with clear subheadings (use bold or ### headings). Each section covers one key point. Weave in data, examples, and mini-stories from the source.
4. Quotable line: Include 1–2 standalone sentences formatted as blockquotes — these are what readers screenshot and share.
5. Closing: Summarize the core message in 1–2 sentences, then add a CTA (follow/like/share).

WeChat-specific rules:

• Write in natural, flowing Chinese — not stiff translation
• Cultural adaptation: replace Western-only references with universally relatable ones, or add brief context for Western examples
• Paragraph length: 3–5 sentences max — long paragraphs lose mobile readers
• Use corner brackets (「」) for emphasis quotes in Chinese text rather than standard quotation marks
• No external hyperlinks in body text (WeChat restricts them) — reference sources by name instead
• Avoid politically sensitive content per platform norms

Step 6: Produce Zhihu Version

Constraints:

• Length: 1,000–4,000 Chinese characters
• Language: Chinese
• Zhihu readers expect depth, evidence, and structured reasoning

Structure:

1. Opening: Frame the content as answering an implicit question. Start with a concise thesis statement or a "conclusion first" pattern.
2. Argument body: Use numbered sections or clear headers. Each section should follow a claim → evidence → implication pattern. Include all relevant data points from the source.
3. Practical advice: If the content is how-to or educational, provide a clear numbered list of actionable steps.
4. Summary: 2–3 sentences wrapping up the core insight.
5. Engagement hook: End with a question to the reader (e.g., "What's your take?" or "What's been your experience?") or a CTA (upvote/bookmark/follow).

Zhihu-specific rules:

• Credibility matters — cite sources, mention research by name, be specific with numbers
• Avoid vague claims — "research shows" is weak; "A 2024 Stanford study found..." is strong
• Use the "conclusion first" pattern if the content supports it — Zhihu readers appreciate direct answers
• Logical structure with headers is expected — walls of text perform poorly
• Tone: knowledgeable but not arrogant; helpful, not preachy
• No fabricated data or unverifiable claims

Step 7: Produce Slack Version

Constraints:

• Length: 300–800 characters ideal for a single message; up to 4,000 max
• Language: Match the team's working language (English by default)
• Internal audience — assumes shared context

Structure:

1. TL;DR line (bold): One sentence summarizing the key takeaway, prefixed with a relevant emoji.
2. Key points (3–5 bullets): Short, scannable bullets — each one actionable or informative. Use bold for emphasis on key terms.
3. Link or reference (optional): "Full article: [title]" or "More details in #channel"
4. Discussion prompt (optional): One question to spark a thread conversation.

Slack-specific rules:

• Use Slack formatting: *bold*, _italic_, > for quotes, • for bullets
• One emoji per key section header max — don't overdo it
• Assume readers will skim in 10 seconds — front-load the value
• Remove all marketing language — this is internal, peer-to-peer communication
• If the source content has action items, call them out explicitly with owner/deadline placeholders
• No "Dear team" or formal openings — get straight to the content

Step 8: Cross-Platform Consistency Check

Before presenting the output, verify:

• Core message preserved: All five versions communicate the same central idea
• Facts are consistent: Statistics, names, and claims match across all versions — nothing fabricated
• Platform constraints met: Character limits respected, formatting matches platform norms
• Language is correct: Chinese platforms (WeChat/Zhihu) use natural Chinese; English platforms use clean English
• Tone matches platform: LinkedIn is professional, Twitter is punchy, WeChat is narrative, Zhihu is analytical, Slack is concise
• CTAs are platform-appropriate: Each CTA matches what users actually do on that platform
• No hardcoded links or paths: All references are relative or user-provided
• No sensitive information exposed: If the source is internal, the Slack version should be marked as such and external versions should be sanitized

Output Format

Present each platform version under a clear header. Include a metadata block at the top summarizing the adaptation:

## Content Adaptation Summary

After all versions, include:

• Adaptation notes: Brief explanation of key choices made during adaptation (e.g., "Replaced the NFL analogy with a soccer reference for Chinese platforms")
• Suggestions: Optional improvements the user could make per platform

Important Notes

• Preserve the author's voice. Each platform version should sound like the same person adapted their message, not like five different ghostwriters.
• Privacy and sensitivity. If the source contains internal data, company names, or sensitive information, flag this before generating external-facing versions (LinkedIn, Twitter, WeChat, Zhihu). The Slack version can retain internal context.
• Cultural adaptation ≠ mistranslation. When adapting between English and Chinese, convey meaning and spirit, not word-for-word translation. Adapt examples and metaphors for the target audience.
• No paid API dependencies. This skill operates entirely through prompt-based generation — no external API calls required.
