Multi-Platform Social Caption Kit
Purpose
This skill takes one core brand message or product brief and generates platform-optimized captions for six major social platforms simultaneously: WeChat Moments (朋友圈), Weibo, Instagram, Facebook, Twitter/X, and LinkedIn. Each caption is adapted to the platform's unique tone norms, length constraints, hashtag conventions, emoji culture, and audience expectations — while preserving a consistent brand voice. "Kit" signals a bundled, all-in-one caption package rather than single-platform generation.
Triggers
- "生成朋友圈文案"
- "social caption pack"

Workflow
- Receive the core message/product brief from user: what to communicate, brand voice description, campaign type, and which platforms to cover.
- If brand voice is not specified, ask clarifying questions about tone, formality, and personality before generation.
- Generate platform-adapted captions:
- WeChat Moments (朋友圈): Conversational, personal tone, 1–2 emoji, no hashtags, optional @mentions - Weibo: More public-facing, hashtag-heavy (#话题#), can be longer, trending topic integration - Instagram: Visual-first context, heavy emoji usage, hashtag block (up to 30), Story-friendly format - Facebook: Community-oriented, engagement-driving questions, link-friendly, longer form OK - Twitter/X: Concise within 280 chars, trending hashtag, thread-compatible - LinkedIn: Professional tone, thought-leadership framing, minimal hashtags (3–5)
- Apply platform-specific best practices: link handling (URL placement differs), emoji density, @mention conventions, and hashtag norms.
- Include a hashtag strategy section per platform: which hashtags, how many, and why.
- Add engagement hooks appropriate to each platform's interaction patterns (questions, polls, CTAs).
- Output as a unified caption pack with clear platform labels.

Safety Rules
- NEVER suggest engagement bait tactics that violate platform TOS (e.g., "tag 3 friends to win")
- NEVER create content that impersonates individuals or brands
- NEVER use a fake persona or fabricated identity in brand voice
- ALWAYS maintain authentic, human tone — the caption should sound like a real person wrote it
- ALWAYS include disclosure reminders for sponsored/paid content
- ALWAYS respect per-platform content policies, age restrictions, and sensitive topic rules
