# X Writer
## Purpose
Generate 3 viral X posts in different proven formats, matched to a creator voice, using battle-tested templates and patterns that drive engagement.
---
## Execution Logic
**Check $ARGUMENTS first to determine execution mode:**
### If $ARGUMENTS is empty or not provided:
Respond with:
"x-writer loaded, proceed with your topic or idea"
Then wait for the user to provide their requirements in the next message.
### If $ARGUMENTS contains content:
Proceed immediately to Task Execution (skip the "loaded" message).
---
## Task Execution
When user requirements are available (either from initial $ARGUMENTS or follow-up message):
### 1. MANDATORY: Read Reference Files FIRST
**BLOCKING REQUIREMENT — DO NOT SKIP THIS STEP**
Before doing ANYTHING else, you MUST use the Read tool to read ALL three reference files. This is non-negotiable:
```
Read: ./references/formats.md
Read: ./references/posts.md
Read: ./references/voices.md
```
**What you will find:**
- **formats.md**: 8 proven post formats with structure templates, psychology, and format-specific rules
- **posts.md**: 49+ proven viral posts organized by format type — the example library
- **voices.md**: Creator voice profiles with writing DNA, signature patterns, and example posts
**DO NOT PROCEED** to Step 2 until you have read all three files and have their content in context.
### 2. Check for Business Context
Check if `FOUNDER_CONTEXT.md` exists in the project root.
- **If it exists:** Read it and use the business context to personalize output (industry terminology, audience pain points, brand voice, company name, products).
- **If it doesn't exist:** Proceed using defaults from "Defaults & Assumptions."
### 3. Analyze Input & Select Voice
From the user's requirements, extract:
- **Topic/idea** — What they want to post about
- **Goal** — What they want the post to achieve (engagement, authority, education, humor)
- **Voice preference** — If they specified a voice or tone
**Voice Matching Logic:**
If the user specified a voice → use that voice directly.
If the user did NOT specify a voice:
1. Analyze the topic and FOUNDER_CONTEXT.md brand voice
2. Auto-suggest the best match based on topic:
- Business advice, mindset, pricing, sales, productivity → suggest **Alex Hormozi**
- Life philosophy, contrarian takes, self-improvement, minimalism → suggest **Naval Ravikant**
- Startup advice, CEO/founder roles, hiring, company building → suggest **Andrew Gazdecki**
- Self-improvement, productivity hacks, fitness + learning, habits → suggest **Dakota Robertson**
- AI trends, tool launches, tech stack recommendations, urgent opportunities → suggest **Machina**
- SaaS growth, AI productivity, founder mindset, revenue strategy → suggest **Ognjen Gatalo**
- Personal responsibility, escaping default paths, harsh reality checks, focus training → suggest **Dan Koe**
3. Ask the user to confirm using AskUserQuestion:
- **[Suggested Voice] (Recommended)** — [one-line description of why it fits]
- **[Other Voice 1]** — [one-line description]
- **[Other Voice 2]** — [one-line description]
- **My own voice** — Natural tone based on FOUNDER_CONTEXT.md brand voice
### 4. Generate 3 Viral Posts
Using the formats, posts, and voice you loaded in Steps 1-3:
1. **Select 3 DIFFERENT formats** from formats.md that best fit the user's topic and goal
2. **Study the example posts** in posts.md for those formats — internalize the rhythm, structure, and length
3. **Apply the selected voice** from voices.md — match their sentence structure, rhythm, and signature patterns (not their exact words or examples)
4. **Draft each post** following the format's structure template, the voice's DNA, and all Writing Rules below
5. **Run each post through the Screenshot Test:** "Would someone screenshot this and share it?" If no → rewrite before continuing
**Critical requirements:**
- Each post must use a DIFFERENT format (no repeats)
- Each post must sound like the selected voice (structural match, not word-for-word copy)
- Each post must be about the user's SPECIFIC topic (not generic advice)
- Each post must follow the format's structure template from formats.md
- Each post must be ready to copy-paste and post immediately — no placeholders
### 5. Format and Verify
- Structure output according to **Output Format** section
- Complete **Quality Checklist** self-verification before presenting output
- If any post feels generic, forced, or wouldn't pass the Screenshot Test → rewrite before presenting
---
## Writing Rules
Hard constraints. No interpretation.
### Core Rules (Apply to ALL posts)
- Maximum 280 characters for single posts. If a post exceeds 280 characters, it must be structured as a thread (each tweet under 280 characters).
- First line is the hook — it determines whether people click "Show more." Make it the strongest line in the post.
- Use line breaks strategically. White space = visual breathing room = readability.
- No hashtags. They reduce reach and look amateur on X.
- No engagement bait ("like if you agree", "RT if this resonates", "thoughts?"). It kills reach.
- No emojis unless the voice or topic specifically calls for it. When used, maximum 1-2 per post.
- Specific numbers > vague claims ("17 strategies" not "many strategies").
- Opinions > facts. X rewards bold takes, not Wikipedia summaries.
- Active voice only. Never passive.
- Present tense preferred.
- Every word must earn its place. If you can cut a word without losing meaning, cut it.
- No "I think" or "In my opinion" — just state the opinion as fact. Confidence is voice.
### Voice-Matching Rules
- Match the voice's SENTENCE STRUCTURE — short choppy lines vs flowing sentences, fragments vs complete thoughts.
- Match their RHYTHM — how they Excerpt, first 6,000 characters of SKILL.md, verbatim from the audited commit. It is text from someone else’s repository, quoted so you can judge it before your agent reads it.
