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
