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#

Step 3: Apply Platform Rules#

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

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
