Platforms: X (Twitter)

Guides X post copy creation and optimization. Use for generating publish-ready posts, threads, and content that performs on X. Suitable for copy agents, design agents (image specs), and video agents (video post specs).

**When invoking**: On **first use**, if helpful, open with 1-2 sentences on what this skill covers and why it matters, then provide the main output. On **subsequent use** or when the user asks to skip, go directly to the main output.

Output: Publish-Ready Copy

This skill enables agents to generate X post copy that can be published directly. Output includes character-counted text, thread structure, and platform-compliant formatting.

Character Limits

| Type | Limit | Notes | |------|-------|-------| | **Standard post** | 280 characters | Most users | | **Premium** | 25,000 characters | X Premium subscribers | | **URL** | Counts as 23 chars | t.co shortens all links | | **Emoji** | ~2 chars each | Varies by emoji |

Optimal Lengths (Engagement)

| Use Case | Characters | Purpose | |----------|------------|---------| | **General** | 71-100 | Sweet spot for engagement | | **Promotional** | 120-130 | Product/offer posts | | **Question** | 60-80 | Drive replies | | **Retweet-friendly** | ~116 | Leaves room for "RT @user:" |

Thread Format

• **Structure**: 3-5 connected posts; number as 1/5, 2/5, etc.
• **First post**: Strong hook; no "thread" in first line
• **Last post**: CTA, summary, or question
• **Each post**: ~80 chars; can stand alone

Post Structure (Hook + Value + CTA)

| Part | Ratio | Guideline | |------|-------|-----------| | **Hook** | 10% | First 1-2 lines; question, fact, or emotion; ~50 chars | | **Value** | 70% | Practical info; use thread for depth | | **CTA** | 20% | Call for reply, question, or action |

End with open question to drive replies. Thread structure can extend impressions ~10x.

Algorithm (Grok AI)

Signal Weights

| Signal | Impact | |--------|--------| | **Replies** | Highest (~54-75x likes); quality > quantity | | **Author replies** | Active reply chains ~75x visibility | | **Bookmark** | 2026 signal; saves boost recommendation | | **Media** | Images/video ~2x; video 2-4x exposure | | **External links** | Reduce score ~50%; prefer internal refs | | **Post limit** | 5-8/day; >10/day reduces later visibility ~80% |

**Content**: Open questions, controversial views, stories; avoid "RT if agree" bait.

TweepCred

| Threshold | Effect | |-----------|--------| | **< 65** | Only last 3 posts enter For You | | **New accounts** | Need +17 to appear in feed | | **Blue V** | Auto 100 points |

Monitor account health; avoid spam, bulk ops, excessive links.

Distribution

Posts tested in small group first; early interaction (first 30 min) decides reach. Niche consistency helps SimClusters match.

Link Optimization

| Practice | Guideline | |----------|-----------| | **Penalty** | External links ~-50%; Regular accounts: link posts 0% engagement since 2025 | | **Placement** | Put link in reply, not main post | | **Ratio** | Max 1 link per 5 posts | | **Premium** | Premium+ safest for links (~0.25-0.3% engagement) | | **Preview** | Title ≤70 chars, description ≤200 chars; 1200×628 image |

Premium Impact

| Tier | Reach | Link posts | |------|-------|------------| | **Regular** | <100/post | 0% engagement | | **Premium ($8)** | ~600/post | ~0.25-0.3% | | **Premium+ ($40)** | ~1550/post | Safest for links |

Premium ~10x reach vs Regular. If X is core channel, Premium helps.

Video

• **Exposure**: 2-4x vs text
• **Length**: 8-30s short video preferred
• **VQV**: High video completion boosts score 2-3x

Content Ratio

| Type | Share | Use | |------|-------|-----| | **Value** | 70% | Education, how-to, insights | | **Interaction** | 20% | Polls, questions, AMA | | **Promo** | 10% | Product, offers |

Twitter Cards + SEO

Cards (og:image, title, description) boost CTR ~64%, engagement ~26%. Use for Social SEO; X traffic can accelerate Google indexing. For programmatic SEO (template + data pages at scale), use programmatic-seo.

Image Specs (for Design Agents)

| Format | Dimensions | Use | |-------|------------|-----| | **Single image** | 1200×675 (16:9) | Best visibility; no crop | | **Square** | 800×800 | Single image | | **Profile** | 400×400 | Avatar | | **Header** | 1500×500 (3:1) | Banner | | **File** | ~5MB; JPG/PNG | Over 5MB may compress |

Output Format

When generating X copy, provide:

1. **Post text** with character count 2. **Hashtags** (if used; 1-3 recommended) 3. **Thread structure** (if thread) 4. **Image specs** (if design agent needs dimensions)
