## What it does

The skill drafts three distinct posts for X from a single prompt, matching specific creator styles such as Alex Hormozi, Naval Ravikant, or Dan Koe. Before writing anything, the agent must inspect three reference files: `./references/formats.md`, `./references/posts.md`, and `./references/voices.md`. These contain 8 structural templates, a library of 49 examples, and distinct voice profiles.

If `FOUNDER_CONTEXT.md` is present in your project root, the skill pulls product details, industry terminology, and target audience pain points. Writing rules enforce a strict 280-character ceiling per tweet, active voice, and zero hashtags or engagement-bait lines like asking for retweets.

Execution will halt if the reference markdown files are missing from the workspace, as reading them is a hard prerequisite before drafting.

## When to use it
- draft three distinct post angles for X on a single topic
- emulate creator voice patterns like Naval or Hormozi without copying their phrases

# 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**
