Skills for Codex and Claude Code

Turn Your Notes into Finished Carousels, Posts and Reels

Three skills turn notes, articles, spreadsheets and video recordings into files you can post right away, such as Instagram carousels, copy for every platform and reels with large captions. You publish them yourself.

What the Results Look Like

Every image comes unchanged from the blind final test of version 2.0.0. The tasks were synthetic, and the businesses, names and numbers in them are invented. You will not see real customers here.

The photos were made by Codex’s built-in image generation. The carousel skill draws the charts from the numbers in the task, and social-reel built the reel covers for the talk recordings in the tasks.

Carousels for Instagram and LinkedIn

  • Cover slide of an Instagram carousel for a fictional balcony garden shop: "Tomaten auf dem Balkon? So starten Sie." above a photo of a potted tomato plant
    Made with social-karussellText in the image is German
  • Slide from the same carousel on a green ground: "Geben Sie den Wurzeln Platz." with the large figure "15 to 20 Liter pro Pflanze"
    Made with social-karussellText in the image is German
  • Cover slide of a carousel for a fictional optician: "Feierabend. Augen müde?" and "6 Tipps für Augen und Brille" above a photo of a desk with glasses
    Made with social-karussellText in the image is German
  • Chart slide for a fictional indoor pool: "Im Sommer sinken die Eintritte." with a line of monthly visits in 2024, lowest point 2,290 in August

Instagram graphics from a content set

  • Instagram graphic from a content set for a fictional baking class provider: "Dein erstes Sauerteigbrot. Vier Zutaten. Und Zeit." above a photo of a loaf
    Made with social-textText in the image is German
  • Instagram graphic from a content set for a fictional bouldering gym: "Dein erstes Mal Bouldern?" above a photo of climbing shoes labelled as an AI image
    Made with social-textText in the image is German

Reel covers

  • Reel cover from a talk about online booking in a hair salon: "Weniger leere Stühle." with a drop from 9 to 2 "No-Shows pro Monat, im Schnitt"
    Made with social-reelText in the image is German
  • Reel cover from a talk about a village shop: "387.000 € Umsatz im ersten vollen Jahr" and "Wie ein Dorf seinen Laden rettet."

What the Skills Never Do

The skills work on your machine and hand you files. The last step is always yours.

Nothing gets posted

There is no live posting and no scheduling. You upload the finished files yourself, whenever and wherever you want.

No social network logins

The skills never log in to a social network or an ad account. Meta ad copy is only ever written to a file.

No money spent

The skills never spend money on your behalf. They do not book ads and do not activate anything.

The Package

Three Skills for Graphics, Copy and Video

You don’t have to name a skill. Describe what you need, and the agent picks the right one. Finished files go to the fertig/ folder, work files to the .arbeit/ folder.

  • Carousels and graphics

    social-karussell

    Turns notes, articles or spreadsheets into Instagram and LinkedIn carousels, single graphics, Pinterest pins and infographics. You get a strong cover, real charts from your numbers and a caption with alt texts. If your agent has built-in image generation (Codex, for example), the skill uses it for photos and illustrations.

    Example: "Turn my notes into an Instagram carousel. Brand colours and logo are in the input folder."

  • Copy for every platform

    social-text

    Writes posts for LinkedIn, Instagram, Facebook, Threads and X, hooks for reels and TikToks, and Meta ad copy. From one article it builds a content set with its own version for each platform, with a finished graphic for Instagram.

    Example: "Turn my blog post into posts for Instagram, Facebook and LinkedIn."

  • Reels with captions

    social-reel

    Cuts vertical reels, Shorts and TikToks from talk, interview or phone recordings. The strongest sentence moves to the start, filler words and pauses go, and large captions in short phrases land automatically in a calm area of the frame. You also get a name title, a cover, a caption and a loudness of -14 LUFS. Short videos with animated text work as well.

    Example: "Turn the recording of my talk into a reel, 30 to 45 seconds."

What is tested

What Is Verified and What Is Not

I’d rather sell you a clear limit than an empty promise.

Blind test on 12 new tasks

I set 12 new, synthetic tasks, four each for carousel and graphic, copy and reel. Codex with GPT-6.1 solved every task twice with and twice without the skills. Three AI models (Claude Sonnet, Claude Opus and GPT) compared the results blind and rated the version with skills better in 52.5 of 72 paired comparisons. A tie counts as half.

Fewer hard errors, more often postable

With the skills the raters found 0 hard errors, without them 7. They said "I would post this" in 23 of 24 cases with the skills and in 17 of 24 without.

Model ratings, no audience data

AI models did the rating, not people and not a real audience. The tasks were synthetic. That is a signal, not proof of more reach or revenue.

Tested with Codex only

I tested on macOS with Codex. Claude Code reads the same skill format, but I did not test the skills there separately. I did not test Windows or Linux.

Facts only from your material

The skills don’t invent numbers or dates. If something is missing, they leave it out and tell you in one sentence at the end what you can add.

Music is not included

The reels come without music. You add your own music in the app you post from.

How it works

Buy, Unzip, Get Started

No subscription. An install script copies the three skills to the right place.

1. Buy and download

Secure payment via Polar. You get the download link by email right after. The ZIP file is only about 33 KB.

2. Unzip and install

One terminal command installs the skills for Claude Code. For Codex add --codex, for a single project --projekt and the folder.

unzip social-media-skills-v2.0.0.zip && cd social-media-skills-v2.0.0 && ./install.sh

3. Start a new session

Start a new session and describe what you need, for example an Instagram carousel from your notes or a reel from your talk recording.

What you need

  • Codex or Claude Code. I tested on macOS with Codex. Claude Code reads the same skill format but was not tested separately.
  • social-text needs nothing else.
  • social-karussell needs Python 3 (3.12 recommended) with Pillow and Playwright including Chromium.
  • social-reel needs Python 3 with Pillow and faster-whisper, plus ffmpeg. No special ffmpeg build is required.
  • With ./install.sh --mit-abhaengigkeiten the script installs the Python packages as well. On a Mac you install ffmpeg with brew install ffmpeg.
  • Windows and Linux are not tested.

Frequently Asked Questions

Everything you need to know before you buy.

Does the package post for me?
No. The skills create files on your machine, such as PNGs, videos and text. They never log in to a network or an ad account, schedule nothing and spend no money. You upload and publish yourself.
What is a skill, anyway?
A skill is a folder with a SKILL.md and scripts that your agent loads when it is needed. You install it once, and from then on it helps with every matching task. You don't have to call it by name.
Does it work with Codex and with Claude Code?
I tested the skills on macOS with Codex. Claude Code reads the same skill format, but I did not test them there separately. The install script handles both targets.
What do I need for everything to work?
social-text needs nothing else. social-karussell needs Python 3 (3.12 recommended) with Pillow and Playwright including Chromium. social-reel needs Python 3 with Pillow and faster-whisper, plus ffmpeg. The install script checks this and gives you the command for anything that is missing.
Where do the facts in my posts come from?
Only from your material, such as notes, articles or spreadsheets. If a number or date is missing, the skill leaves it out and tells you in one sentence at the end what you can add.
Is there music in the reels?
No, music is not included. You add your own music in the app you post the reel from.
Does it run on Windows?
I tested everything on macOS. I haven't tested Windows or Linux, so I can't promise it works there.
Is this a subscription?
No. You pay once and use the skills for as long as you like. Updates are included in your purchase.
Can I use the skills for client projects?
Yes. Your own projects and client projects are explicitly allowed. Reselling or redistributing the skills themselves is not.
How does checkout work and who issues the invoice?
Payment runs through Polar as the merchant of record. Polar handles EU VAT and sends you an invoice automatically. Right after your purchase you get the download link by email.
