X Post Craft - Algorithm-Driven Post Creation

Create high-engagement X/Twitter posts based on insights from X's public algorithm (Phoenix/Grok scoring system).

Reference: This skill is based on insights from x-algorithm - X's open-source recommendation algorithm.

Algorithm Fundamentals

Scoring Signals (by importance)

X's algorithm predicts engagement probabilities and weights them into a final score:

Positive Signal	Description	Weight
dwell_time	Time spent reading	Very High
favorite	Like	High
retweet	Repost	High
reply	Reply	High
quote	Quote post	High
share / share_via_dm / copy_link	Share actions	Medium-High
follow_author	Follow	Medium
profile_click	Profile visit	Medium
vqv	Video quality view (30s+)	Video only

Negative Signal	Description	Impact
not_interested	Not interested	Negative
block_author	Block	Strong Negative
mute_author	Mute	Strong Negative
report	Report	Strong Negative

Author Diversity Penalty

Same author's consecutive posts get score decay. → Quality over quantity - one great post beats multiple mediocre ones

In-Network vs Out-of-Network

Reaching non-followers requires higher scores. → Universal value spreads better than niche content

Workflow

Step 1: Information Gathering (via AskUserQuestion)

Collect from user:

Required:
- Topic (service/feature/news/insight)
- Core message (one sentence)
- Target audience

Optional:
- Tone (expert/casual/provocative/educational)
- Format (single/thread/quote RT)
- Visual assets (image/video)
- Target language for output

Step 2: Analysis & Design

From collected info:

1. Hook Design: What stops the scroll in first 1-2 lines
2. Value Proposition: Why worth reading
3. Action Trigger: Which engagement to optimize for
4. Risk Avoidance: Prevent negative signals

Step 3: Generate Variations

Minimum 3 patterns:

Pattern	Characteristic
A: Classic	Clear value, easy to read
B: Hook-Heavy	Strong opening, curiosity gap
C: Discussion-Starter	Strong opinion, invites replies

Step 4: Algorithm Explanation

For each variation:

• Why this structure increases score
• Which signals it targets
• Potential risks and mitigations

Step 5: Feedback Loop

Collect user preference, refine final version

Generation Rules

Structure Template (Single Post)

[HOOK] 1-2 lines to stop the scroll
  ↓
[BODY] Deliver value
  ↓
[CTA] Call to action (optional)

Hook Patterns

Pattern	Example	Goal
Number Impact	"5 things I learned after 10 years in tech"	Specificity builds trust
Contrarian	"Everything you know about X is wrong"	Triggers discussion
Empathy	"Struggling with X? Here's what worked"	Target identification
Conclusion First	"Bottom line: You should do X"	Clarity
Story	"Yesterday something happened that changed my view"	Curiosity

Character Guidelines

Format	Recommended Length	Reason
Single (short)	100-140 chars	Easy to RT
Single (medium)	200-280 chars	Value + completion
Thread post 1	~140 chars	Hook focus
Thread post 2+	200-280 chars	Expand content

Visual Asset Recommendations

Asset Type	Algorithm Effect
Infographic	dwell_time+, share+
Screenshot	Credibility, specificity
Video (30s+)	vqv_score activation
Image carousel	photo_expand+

Thread Design

Structure Template (Thread)

1/N [HOOK] Why read this + "Thread below"
2/N [CONTEXT] Background or problem setup
3 to N-2/N [CORE] Main content (1 point per post)
N-1/N [SUMMARY] Key takeaways
N/N [CTA] Follow/RT/comment request

Thread Hook Examples

• "X things you need to know about [topic] (thread)"
• "I researched [topic] and found something surprising. Here's what I learned 👇"
• "After X years in [industry], here's what I wish I knew (long, so thread)"

Edit Mode

For improving existing drafts:

Analysis Criteria

1. Hook Strength: Does line 1 stop the scroll?
2. Value Clarity: Is the benefit obvious?
3. Dwell Factor: Elements that make people read longer?
4. Action Trigger: Clear what to do next?
5. Risk Check: Any negative signal triggers?

Avoid (Negative Signal Prevention)

• Excessive provocation/aggressive tone (triggers block/mute)
• Obvious clickbait (triggers not_interested)
• Hashtag spam
• False/exaggerated claims
• Personal attacks
