Multi-Platform Social Media Growth Skill for Developer Communities

1. Platform Queue & Rotation

Supported Platforms (10 active)

Dev.to → Quora → Twitter/X → Bluesky → Hacker News → Reddit → GitHub → Product Hunt → Hashnode → Medium → (loop)

Rotation Rules

1. Each trigger executes 3 platforms, then stops
2. Next trigger resumes from breakpoint (e.g., stopped at Bluesky → next starts at HN)
3. Breakpoint can cross cycle boundaries (Medium done → next cycle starts at Dev.to)
4. Platforms execute back-to-back within a trigger — no waiting between them
5. Each cycle uses a fresh content angle (never repeat the previous cycle's theme)

2. Frequency & Cooldown

Cron Trigger

• Every 30 minutes (*/30 * * * *)
• Cron is a fallback — if already executing, skip

Per-Platform Posting Cooldowns

During cooldown: Only perform engagement actions (likes/upvotes/stars/follows), no new posts/comments.

3. Action Diversity Rules

Iron rule: Each platform requires ≥3 different action types per visit (not 3x the same type)

Platform Action Menus

Minimum Per Visit

• 2-3 likes/upvotes (baseline)
• At least 1 "light social" action: Follow / Bookmark / Repost / Star
• At least 1 "content" action: Reply / Original post / Comment / Answer
• Every 2-3 cycles: 1 "deep" action: DM / long article / Twitter Thread / join community

4. Content Strategy

Content Pillars

Link Mention Rules

• ~50% of original content naturally mentions your product URL
• Mentions must feel organic: sharing discoveries/recommendations/experiences, never ad-like
• Other 50% is pure value content with no links (maintains credibility)
• Max 30% of total activity should contain links

Content Angle Rotation (change each cycle)

Example angles used in production:

• Trust vs verify AI output
• AI pair programming: lead vs follow
• Shipping real AI tools / indie hacker speed
• Dev tools product-market fit
• Open source as distribution strategy
• AI testing & quality gap
• DX polish as competitive advantage
• Technical debt in AI-generated code

Platform Adaptation

• Twitter: 280 char limit, punchy, 1-3 hashtags
• Bluesky: 300 char limit
• Dev.to/Hashnode: Long comments/articles, technical depth
• Quora: Answer format, personal experience + data
• Medium: Response format, insightful
• HN: Minimal technical style, no emoji or hashtags
• Reddit: Match subreddit culture, avoid over-promotion
• GitHub: Technical comments, code-related
• Product Hunt: Product discussion perspective

5. Chrome MCP Toolchain

Only use mcp__beta__* tools (not mcp__chrome__*)

Core Workflow

take_snapshot → save to /tmp/xxx.txt → Grep for UIDs → interact

Key Technical Patterns

Universal Snapshot Flow

1. mcp__beta__take_snapshot → capture page DOM
2. Save to /tmp/{platform}-c{cycle}.txt
3. Grep search for target element UIDs
4. Execute click / fill / type_text using UIDs

Twitter/X Posting

• Navigate to /compose/post for clean composer
• Clear existing text: Meta+A + Backspace (via press_key)
• Check length: evaluate_script reading textbox textContent.length

Dev.to Comment Injection

() => {
  const ta = document.getElementById('text-area');
  if (!ta) return 'not found';
  const nativeSet = Object.getOwnPropertyDescriptor(
    Object.getPrototypeOf(ta), 'value'
  ).set;
  nativeSet.call(ta, "YOUR COMMENT TEXT");
  ta.dispatchEvent(new Event('input', {bubbles: true}));
  ta.dispatchEvent(new Event('change', {bubbles: true}));
  return 'done';
}

Medium Contenteditable Focus

() => {
  const ces = document.querySelectorAll('[contenteditable="true"]');
  for (const ce of ces) {
    if (ce.closest('[role="textbox"]') || 
        ce.textContent.includes('What are your thoughts')) {
      ce.focus();
      const range = document.createRange();
      range.selectNodeContents(ce);
      range.collapse(false);
      const sel = window.getSelection();
      sel.removeAllRanges();
      sel.addRange(range);
      return 'focused';
    }
  }
  if (ces.length > 0) { ces[0].focus(); return 'focused first'; }
  return 'not found';
}

Quora Editor Focus

() => {
  const editor = document.querySelector('[contenteditable="true"].doc');
  if (!editor) return 'not found';
  editor.focus();
  const range = document.createRange();
  range.selectNodeContents(editor);
  range.collapse(false);
  const sel = window.getSelection();
  sel.removeAllRanges();
  sel.addRange(range);
  return 'focused';
}

6. Safety & Anti-Ban Rules

Rate Limiting

• Don't rapid-fire likes (spread evenly)
• Never post identical text across platforms
• Link content <30%, 70% pure engagement/value
• If rate limited or warned → stop that platform for 24 hours
• Human-like timing: don't post at exact intervals

Platform Link Restrictions (tested)

Account Management

• Prefer Google OAuth for new signups
• Consistent username/display name across platforms
• Consistent bio mentioning your product
• Only ask for human help on CAPTCHA/SMS verification

7. Continuous Optimization

1. Review every 3-5 cycles: Which platforms/angles got engagement?
2. Content evolution: Rotate topics based on platform trending, never repeat
3. Platform deep-dive: Invest more in high-conversion platforms (Dev.to long posts, Quora long answers, HN technical discussions)
4. Traffic tracking: Periodically check analytics and per-platform engagement data
5. Skill iteration: Update this skill when discovering new effective strategies
6. Deep actions: Execute one deep action every 2-3 cycles (long article / Thread / DM / join community)

8. Localized UI Label Mapping

If your browser is in a non-English locale, common button labels:
