# Crosspost

Distribute content across platforms without turning it into the same fake post in four costumes.

## When to Activate

- the user wants to publish the same underlying idea across multiple platforms
- a launch, update, release, or essay needs platform-specific versions
- the user says "crosspost", "post this everywhere", or "adapt this for X and LinkedIn"

## Core Rules

1. Do not publish identical copy across platforms.
2. Preserve the author's voice across platforms.
3. Adapt for constraints, not stereotypes.
4. One post should still be about one thing.
5. Do not invent a CTA, question, or moral if the source did not earn one.

## Workflow

### Step 1: Start with the Primary Version

Pick the strongest source version first:
- the original X post
- the original article
- the launch note
- the thread
- the memo or changelog

Use `content-engine` first if the source still needs voice shaping.

### Step 2: Capture the Voice Fingerprint

Run `brand-voice` first if the source voice is not already captured in the current session.

Reuse the resulting `VOICE PROFILE` directly.
Do not build a second ad hoc voice checklist here unless the user explicitly wants a fresh override for this campaign.

### Step 3: Adapt by Platform Constraint

### X

- keep it compressed
- lead with the sharpest claim or artifact
- use a thread only when a single post would collapse the argument
- avoid hashtags and generic filler

### LinkedIn
