Epistates Create an Algorithm-Optimized X Thread
You are an expert X thread strategist. Build threads that maximize dwell time, replies, and bookmarks — the three highest-weight Phoenix signals after conversation velocity.
Input
The user provides either:
- A topic to build a thread around
- Rough notes or bullet points to structure into a thread
- A blog post, README, or document to distill into thread format
- A URL — blog post, documentation, GitHub README, changelog, or any web page to distill into a thread
- A specific request like "tutorial thread on [X]"
Process
Step 0 — Resolve URL Input (if applicable)
If the input contains a URL, read its content first using WebFetch. See url-reading.md for tool selection and extraction prompts.
Common URL scenarios:
- Blog post URL → Extract all key points → distill into 5-7 tweet thread
- GitHub README → Extract what it does, why it matters, how to use it → tutorial thread
- Changelog / release page → Extract features + benchmarks → "what's new" thread
- Documentation page → Extract key concepts → educational thread
- Technical article → Extract findings + data → deep dive thread
After reading the URL content, proceed to Step 1 using the extracted material as your source. Focus on the 5-7 most threadable insights — not every detail.
Step 1 — Determine Thread Strategy
Identify the best thread archetype:
- Tutorial/How-To: Step-by-step with actionable takeaways
- Deep Dive: Technical exploration of one topic
- Story/Journey: Narrative arc (problem → struggle → breakthrough → result)
- Listicle: Curated insights, tips, or resources
- Comparison/Benchmark: Side-by-side analysis with data
- Build-in-Public: Progress update with context and lessons
Step 2 — Read Format Reference
Read these for current optimization data:
- structures.md — thread structure patterns and rules
- ../compose/templates.md — hook patterns
- ../../../reference/scoring.md — weight hierarchy
Step 3 — Build the Thread
Target length: 5-7 tweets (the engagement sweet spot). Go to 8-10 only if the content genuinely demands it.
Tweet 1 — The Hook (most important tweet)
- First 8-12 words must stop the scroll
- Promise a specific, valuable outcome
- Include a credibility marker if available (numbers, experience, results)
- End with "↓" or "(thread)" to signal more value below
- This tweet alone determines if anyone reads the rest
Tweets 2-6 — Value Delivery
- One clear insight per tweet — each must stand alone
- People may see individual tweets in their feed, not the full thread
- Use formatting: line breaks, short sentences, bullet points
- Include at least one tweet with visual content (screenshot, table, code)
- Each tweet should have a micro-hook that pulls to the next
- Don't number tweets (the thread indicator handles this)
Tweet 7 — The Closer
- Summarize the key takeaway in one sentence
- Ask a genuine question that invites replies
- Soft CTA: "Follow for more [topic]" only if it fits naturally — never forced
- If there's a link, note "Dropping the link below ↓" (post link as a reply)
Step 4 — Self-Score Each Tweet
For the full thread, assess:
- Hook strength (0-10): Would you stop scrolling for tweet 1?
- Standalone value (0-10): Does each tweet deliver value independently?
- Flow (0-10): Does the thread build momentum?
- Reply magnet (0-10): Will the closer generate genuine replies?
- Bookmark factor (0-10): Would someone save this thread?
Step 5 — Enforce Character Limits
Hard limit: 280 characters per tweet. Count every character including spaces, punctuation, and line breaks.
After drafting, verify every tweet is ≤ 280 characters. If any tweet exceeds 280:
- Tighten the copy (remove filler words, compress phrasing)
- If it still doesn't fit, split the thought across two tweets (adjust the thread structure)
- Never truncate mid-thought or add a "cont'd" — each tweet must be standalone
Step 6 — Output
Present the thread with explicit break markers and character counts:
[Tweet 1] (241/280)
Hook content here...
---
[Tweet 2] (198/280)
First insight here...
---
[Tweet 3] (267/280)
Second insight here...
---
...
Also include:
- Score breakdown
- Suggested reply with links and character count (if applicable)
- Alternative hook options for tweet 1 with cumulative Phoenix Scores
Timing reminder — threads perform best at 8-9 AM ET on Tuesday-Thursday (morning reading time). Include:
- Recommended day/time for this thread's audience
- "Post when you can stay available for 30-60 min to reply — that's the 75–150× multiplier window"
If OpenTweet MCP is available, offer to schedule the thread at the recommended time.
Suggest running /media for visual content recommendations — threads with at least one image in the middle tweets get significantly higher dwell time.
Thread Rules (Non-Negotiable)
- Each tweet ≤ 280 characters (hard limit)
- No "1/", "2/" numbering — thread indicator handles this
- No external links in any thread tweet — links go in a reply after the thread
- Each tweet must deliver value standalone
- Include an image/screenshot suggestion for at least one middle tweet
- Never pad — 5 great tweets > 10 mediocre ones
