Write long-form X (Twitter) posts and threads in a founder/CEO voice. Use when drafting X articles, long tweets, thought leadership threads, or viral content. Produces contrarian, data-backed posts with ASCII diagrams and code block visuals. Includes mandatory AI humanizer pass (24-pattern detector) before finalizing.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
10 rules. About 0 are common, 9 are distinctive, and 1 is very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈9
Distinctive · estimate
This author's own choices. Worth a look.

Tied to their project's names, files or tools. Probably skip.

Never write "This is not X.

Start at 100. Deduct points per the rubric in ../content-ops/experts/humanizer.md.
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

X Long-Form Post Writer
Write posts for X in your founder/CEO's authentic voice. Every post should feel like a real person wrote it — not a content team, not a bot.
See references/founder-voice.md for the founder voice template. Customize it with your founder's real patterns.
Voice Rules
- Simple declarative sentences. Short paragraphs.
- Contrarian angles backed by specific numbers and real examples.
- No corporate speak. No "I'm excited to share." No emoji in body text.
- Open with a hook that stops the scroll — contrarian claim, surprising number, or uncomfortable truth.
- End with a payoff: uncomfortable truth → "worth it" resolution.
Structure
- Hook (1-2 lines) — Contrarian claim or surprising stat
- Setup (2-3 lines) — Establish credibility/context fast
- Sections — Each follows: problem → what actually happened → fix/lesson
- ASCII diagram — At least one per post (see below)
- Uncomfortable truth — The insight most people avoid
- Payoff — Was it worth it? Yes, and here's why.
ASCII Diagrams (MANDATORY)
Every post MUST include at least one ASCII diagram in a code block. These break up walls of text and make complex systems visual.
Use box-drawing characters:
┌─────────┐ ┌─────────┐ ┌─────────┐
│ Input │───►│ Process │───►│ Output │
└─────────┘ └─────────┘ └─────────┘Diagram types to use:
- System architecture — boxes connected by arrows showing how components relate
- Before/after — side-by-side comparison of old vs new state
- Flow diagrams — decision trees, pipelines, sequences
- Hierarchy — org charts, priority stacks, dependency trees
- Metrics — simple bar charts using block characters (█ ▓ ░)
Keep diagrams:
- Under 40 chars wide (mobile rendering)
- Simple enough to parse in 3 seconds
- Labeled clearly — no ambiguous boxes
Example — system flow:
Input (60s)
│
▼
┌──────────┐
│ Process │ step 1
└────┬─────┘
▼
┌──────────┐
│ Dispatch │ step 2
└────┬─────┘

OutputExample — metrics visualization:
Performance by Category:
Category A ████████████ 100%
Category B ████████░░░░ 67%
Category C ░░░░░░░░░░░░ 0%Formatting for X
- X articles support markdown-like formatting in long posts
- Use code blocks (```) for ASCII art — they render in monospace on X
- Bold with asterisks where supported
- Keep paragraphs to 1-3 sentences max
- Line breaks between every thought
Content Sources
Pull from real data whenever possible:
- Real metrics from your business
- Specific incidents and debugging stories
- Actual decisions made and why
Never fabricate metrics. Use real numbers or don't use numbers.
Input Format
User provides:
- Topic: What the post is about
- Angle: The contrarian or unique framing
- Source material: Real examples, data, incidents (optional)
Output
Deliver the complete post ready to paste into X. No preamble, no "here's your post" — just the post itself.
If the post would work better as a thread (>1500 chars), split into numbered tweets with each one standalone valuable.
Reference
See references/founder-voice.md for extended voice examples and patterns. Customize with your founder's real voice.
Humanizer Checklist (MANDATORY — Run Before Finalizing)
Before returning any X article draft, check against ALL 24 humanizer patterns. If any pattern is detected, rewrite that section.
For the full humanizer expert scoring rubric, see: ../content-ops/experts/humanizer.md
CRITICAL: No "Not X, It's Y" Constructions
Never write "This is not X. This is Y." or "That is not X, that is Y." or any variant. These are the #1 AI slop tell. Say what something IS directly. Don't define by negation.
Banned Vocabulary (never use these)
delve, tapestry, landscape (abstract), leverage, multifaceted, nuanced, pivotal, realm, robust, seamless, testament, transformative, underscore (verb), utilize, whilst, keen, embark, comprehensive, intricate, commendable, meticulous, paramount, groundbreaking, innovative, cutting-edge, synergy, holistic, paradigm, ecosystem, Additionally, crucial, enduring, enhance, fostering, garner, highlight (verb), interplay, intricacies, showcase, vibrant, valuable, profound, renowned, breathtaking, nestled, stunning
Pattern Checklist
- ☐ No significance inflation ("pivotal moment", "stands as", "is a testament")
- ☐ No undue notability claims (listing media mentions without context)
- ☐ No superficial -ing phrases ("highlighting", "showcasing", "underscoring")
- ☐ No promotional language ("boasts", "vibrant", "profound", "commitment to")
- ☐ No vague attributions ("Experts believe", "Industry reports suggest")
- ☐ No formulaic "despite challenges... continues to" structures
- ☐ No AI vocabulary clustering (multiple banned words in one paragraph)
- ☐ No copula avoidance ("serves as", "stands as" — just use "is")
- ☐ No negative parallelisms ("It's not just X, it's Y")
- ☐ No rule-of-three forcing (triple adjectives, triple parallel clauses)
- ☐ No synonym cycling (varying terms for the same thing unnecessarily)
- ☐ No false ranges ("from X to Y" on no meaningful scale)
- ☐ No em dash overuse (max 1 per 200 words)
- ☐ No mechanical boldface emphasis
- ☐ No inline-header vertical lists (bolded label + colon pattern)
- ☐ No Title Case In Every Heading
- ☐ No emoji decoration on headings/bullets
- ☐ No curly quotation marks
- ☐ No collaborative artifacts ("I hope this helps", "Let me know")
- ☐ No knowledge-cutoff disclaimers
- ☐ No sycophantic tone ("Great question!")
- ☐ No filler phrases ("In order to", "It is important to note")
- ☐ No excessive hedging ("could potentially", "might have some effect")
- ☐ No generic positive conclusions ("The future looks bright", "Exciting times ahead")
Humanizer Scoring
Start at 100. Deduct points per the rubric in ../content-ops/experts/humanizer.md.
- 90-100: Human-sounding. Clean. Ship it.
- 70-89: Minor AI tells. Quick fixes needed.
- 50-69: Obvious AI patterns. Significant rewrite needed.
- 0-49: Full rewrite.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
