X Longform Launch System

Turn a real project build into a launch-ready X / Twitter longform story, with a cover image, GPT image2 explainer visuals, workflow proof screenshots, and archive-ready publishing materials.

This is a Codex skill for founders, builders, AI operators, creators, and open-source maintainers who want to publish a project with more proof and structure than a normal announcement post.

What It Does

• Writes X Article / longform launch narratives from real project evidence
• Extracts reusable writing routines from reference X posts without copying the text
• Produces a launch story structure: real moment, proof, capability points, system insight, open-source CTA, distribution
• Plans premium X cover images and GPT image2 explainer graphics
• Guides workflow screenshot boards that prove the project actually shipped
• Archives the longform copy, image paths, and publishing notes to local files or Feishu/Lark docs

When To Use It

Use this skill when you are launching:

• an open-source project
• a Codex skill
• an AI product or AI Agent
• a brand-to-launch workflow
• a Remotion / Seedance / GPT image workflow
• a productized build process that should become an X Article or thread

Core Workflow

1. Read the reference X post or article.
2. Extract the writing mechanism: opening, proof, capability points, insight, CTA.
3. Gather project facts, files, screenshots, GitHub links, and launch assets.
4. Write the longform post with short paragraphs and concrete proof.
5. Generate or plan the visual pack:
   • X Article cover
   • GPT image2 explainer image
   • writing routine / workflow diagram
   • real workflow screenshot board
6. Save the output locally and optionally archive it to Feishu/Lark.

Example Prompt

Use $x-longform-launch-system to turn this open-source Codex skill into a launch-ready X longform post. Create the cover direction, GPT image2 explainer prompts, screenshot proof board plan, and Feishu archive structure.
