Social Post Writer Skill

Social Post Writer Skill

Create social media content optimized for LinkedIn, Instagram, or X/Twitter. Posts can be standalone (from a topic) or derived from an existing blog article.

Workflow

Standalone Mode

Initialize → Plan → Research (light) → Draft → Review → Translate → Finalize

Derive Mode

Initialize → Read Source Article → Plan Adaptation → Draft → Review → Translate → Finalize

Phase 1: Initialize

1. Load author profile from database
2. Load platform defaults from settings (platform_defaults.<platform>)
3. Calculate effective tone:

   effective_formality = clamp(author.formality + platform.tone_adjustment.formality_offset, 1, 10)
   effective_opinionated = clamp(author.opinionated + platform.tone_adjustment.opinionated_offset, 1, 10)
   

4. Create folder structure:
   • Standalone: Use create-article-folder.ts --platform <platform>
   • Derive: Use create-article-folder.ts --platform <platform> --derive-from <id>

Phase 2: Plan / Plan Adaptation

Standalone

• Identify the core message (1 sentence)
• Define the target audience for this platform
• Outline the key points (3-5)
• Choose the structure template for the platform

Derive Mode

• Read the source blog article completely
• Extract: main thesis, key arguments, supporting examples, takeaways
• Select which themes translate best to this platform
• Plan adaptation strategy (what to keep, what to restructure, what to drop)

Phase 3: Research (Light)

• Skip for derive mode (source article already researched)
• For standalone: 2-3 targeted searches, not the full blog research process
• Focus on current data, trending angles, platform-specific context

Phase 4: Draft

Voice Adjustment

Apply the effective tone calculated in Phase 1. See references/platform-voice-guide.md for detailed guidelines per platform.

Platform-Specific Drafting

See the platform reference files for structure templates:

• LinkedIn: references/linkedin-format.md
• Instagram: references/instagram-format.md
• X/Twitter: references/x-format.md

Output File Naming

Platform	Files
LinkedIn	{slug}.linkedin.{lang}.md
Instagram	{slug}.instagram.{lang}.md + {slug}.instagram.carousel.{lang}.md
X/Twitter	{slug}.x.tweet.{lang}.md + {slug}.x.thread.{lang}.md

Phase 5: Review

Platform Constraint Compliance Checklist:

• Character/word limits met
• Hashtag count within range
• Required structural elements present (hook, CTA, etc.)
• Tone matches effective tone (not base author tone)
• No blog-article assumptions (e.g., "as we discussed in section 3")
• Platform-appropriate formatting (line breaks, emoji usage)

For derive mode additionally:

• Content stands alone (reader doesn't need the blog article)
• Key value proposition preserved from source
• No orphaned references to companion project or code examples

Phase 6: Translate

• Translate to each additional language in author's profile
• Maintain platform constraints in all languages
• Hashtags: keep some universal, translate others
• Emojis: keep as-is (universal)

Phase 7: Finalize

Database Update

Insert article row with:

• platform: "linkedin" | "instagram" | "x"
• derived_from: source article ID (if derive mode)
• platform_data: JSON with platform-specific structured content
• status: "draft"
• output_folder: folder path
• output_files: per-language file paths

Platform Data JSON Structures

LinkedIn:

{
  "hook": "Opening 2-3 lines...",
  "body": "Main content...",
  "cta": "Call to action...",
  "hashtags": ["#Laravel", "#WebDev", "#PHP"],
  "word_count": 580
}

Instagram:

{
  "caption": {
    "text": "Full caption text...",
    "visible_preview": "First 125 chars...",
    "hashtags": ["#laravel", "#php", "#webdev", "..."],
    "char_count": 1850
  },
  "carousel": {
    "slide_count": 7,
    "slides": [
      { "number": 1, "title": "Rate Limiting in Laravel", "body": "...", "visual_direction": "..." },
      { "number": 2, "title": "Why It Matters", "body": "...", "visual_direction": "..." }
    ]
  }
}

X/Twitter:

{
  "tweet": {
    "text": "Single tweet text...",
    "char_count": 265,
    "hashtags": ["#Laravel", "#PHP"]
  },
  "thread": {
    "tweet_count": 8,
    "tweets": [
      { "number": 1, "text": "Thread opener...", "char_count": 275 },
      { "number": 2, "text": "Key point 1...", "char_count": 260 }
    ]
  }
}

Companion Projects

Social posts do NOT get companion projects. If derived from a blog article that has one, link to it:

"Full working example in the blog post: [link]"
