When to Use

• User has articles/data and wants to create social media posts
• User wants to write a post in a specific format
• User needs content for any platform: LinkedIn, Facebook, Twitter/X, TikTok, Threads
• User asks to "write a post", "viết bài", "tạo content" from any source material
• Works best after using the content-research skill to gather sources

Core Workflow

Step 1: Gather Inputs

Collect from the user (ask if not provided):

1. Source material (required) — article, URL, summary, or raw data
2. Platform (default: LinkedIn) — LinkedIn / Facebook / Twitter/X / TikTok / Threads
3. Content format (default: toplist) — see 6 formats below
4. Tone (default: default) — see Tone Presets
5. Length (default: medium) — short/medium/long
6. Language (default: Vietnamese) — English or Vietnamese
7. Number of posts (default: 1)

Step 2: Select Format

Read the appropriate format reference file:

| Format | File | Best For |

|--------|------|----------|

| 📋 Toplist | references/format-toplist.md | Numbered lists with data |

| 💡 POV | references/format-pov.md | Bold opinions backed by data |

| 🏢 Case Study | references/format-case-study.md | Deep-dive one story |

| 🛠️ How-to | references/format-how-to.md | Step-by-step guides |

| 📖 Story | references/format-story.md | Narrative, emotional journey |

| 🎯 Hook-List-CTA | references/format-hook-list-cta.md | Facebook viral format |

Step 3: Apply Platform Rules

Read references/platform-rules.md for platform-specific constraints. Quick reference:

| Platform | Max length | Style | Hashtag |

|----------|-----------|-------|---------|

| LinkedIn | 3,000 chars | Professional, data-driven | 3-5 tags |

| Facebook | 63,206 chars | Conversational, emotional, story | 0-3 tags |

| Twitter/X | 280 chars | Punchy, hook-heavy | 1-2 tags |

| TikTok | 2,200 chars (caption) | Casual, trendy, FOMO | 5-10 tags |

| Threads | 500 chars | Conversational, casual | 0-2 tags |

Step 4: Build the Prompt

Combine:

1. Brand context — read references/brand-context.md
2. Format instructions — from selected format file
3. Platform rules — from references/platform-rules.md
4. Source material — articles/data provided
5. Tone + Language + Length instructions

Step 5: Generate Content

Output rules (non-negotiable):

• Plain text only — no markdown rendering on social platforms
• ZERO asterisks — no , no *
• No em dashes (—) — use - or comma
• No source URLs in post body
• No markdown (#, [], ())
• Short paragraphs — 1-2 sentences max
• Data-driven — every claim backed by numbers
• For emphasis: use CAPS on 1-2 key words
• Lists: use numbers (1. 2. 3.) or arrows (→)
• Emoji: use naturally per platform style (Facebook/TikTok: more; LinkedIn: 2-3 max)

Step 6: Present and Refine

Offer after generating:

• Regenerate with different format/tone/length/platform
• Create variants for A/B testing
• Generate versions for multiple platforms simultaneously
