Build In Public

Build in Public - Social Media Post Generator

This skill helps developers create engaging social media content from their Claude Code sessions for the #BuildingInPublic and #CodingInPublic communities.

Capabilities

• Parse Claude Code session transcripts to extract highlights
• Generate platform-appropriate posts for:
  • Twitter/X: Short posts (280 chars) and threads
  • BlueSky: Short posts (300 chars)
  • LinkedIn: Medium-length professional updates
  • Instagram: Long-form captions with hashtags
  • Mastodon: Medium posts with hashtags
• Track session metrics (files created, commits, bugs fixed, etc.)
• Output both markdown (human-readable) and JSON (for automation)

When to Activate

Activate this skill when the user:

• Asks to create social media posts about their coding
• Mentions "building in public" or "coding in public"
• Wants to share their progress on Twitter, X, BlueSky, LinkedIn, or Instagram
• Asks for a session summary to share
• Mentions #BuildingInPublic or similar hashtags
• Says things like "I want to tweet about this" or "post this to social media"

Commands Available

• /build-in-public:generate - Generate posts from the current session
• /build-in-public:preview - Preview session activity before generating

How to Generate Posts

When the user wants to create social media content:

1. Preview first (optional): Run /build-in-public:preview to show them what happened in the session

2. Generate posts: Run the generation script:

   python3 "${CLAUDE_PLUGIN_ROOT}/scripts/generate_posts.py" --output . --json
   

3. Present the best options: Show the user 1-2 ready-to-post short posts and mention the full file has more options

4. Offer customization: Ask if they want to emphasize certain aspects or add custom context

Post Formats

Short Posts (Twitter/X, BlueSky)

• Max 280 characters
• Include 1-2 relevant hashtags
• Focus on one key accomplishment
• Use emojis sparingly but effectively

Threads (Twitter/X)

• 4-6 tweets
• Start with a hook
• End with engagement question
• Each tweet under 280 chars

Medium Posts (LinkedIn)

• 500-700 characters
• Professional tone
• Bullet points for accomplishments
• Include relevant hashtags at the end

Long Form (Instagram)

• 1000+ characters
• Storytelling format
• Multiple hashtags (up to 30)
• Include call-to-action

Output Files

The generator creates:

• build-in-public_[timestamp].md - Human-readable posts with all options
• build-in-public_[timestamp].json - Structured data for automation tools

Integration with Publishing Tools

The JSON output can be consumed by automation tools to publish posts. The structure:

{
  "summary": {
    "session_id": "...",
    "project_name": "...",
    "files_created": [...],
    "git_commits": [...],
    ...
  },
  "posts": {
    "short": ["post1", "post2"],
    "thread": ["tweet1", "tweet2", ...],
    "medium": ["linkedin post"],
    "long": ["instagram caption"],
    "hashtags": ["#BuildingInPublic", ...]
  }
}

Tips for Great #BuildingInPublic Content

1. Be specific: "Added user authentication" beats "worked on the app"
2. Show numbers: "Fixed 3 bugs, created 5 files" is more engaging
3. Include the struggle: Bugs fixed = relatable content
4. End with engagement: "What are you building?" invites responses
5. Use relevant hashtags: Match the tech stack (#Python, #React, etc.)
