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
