The basics

What is a skill?

A skill is not software. It is an instruction document that Claude picks up on its own when it fits. No install, no interface, just text that gives the model a fixed way of working. This bundle holds six: one captures your profile, the rest write, spar, pitch, design and build your site from it. Together they let Claude work in your voice, every time.

Consistency

The same tone, the same structure, every time. No guesswork per chat.

Speed

The thinking steps are set. Claude runs through them on its own, without repeated explaining.

Guarding

The skill guards the quality bar. Anything below standard gets reworked.

Before and after

The same model. Your voice.

On the left, Claude the way everyone opens it. On the right, the same Claude, with the six skills from this bundle, fed by your profile, triggered automatically on the right question.

How it looks

Under the hood

Before and after

Yesterday at six the crew was already on location. One camera, two lights, and a story that told itself.

Bonus · available separately

Build and maintain your own studio site

Let Claude build a video-forward portfolio one-pager in the style you choose: a work grid that plays video on hover, a showreel, and a deploy you keep in your own hands. And then the same skill maintains the site — adding a new project, swapping videos, updating text, redeploying — without breaking the structure.

build & maintain

site-builder

site-builder.skill

A video-driven one-pager in the style you choose — build and maintain.

€24

Claude skill — site-builder

Four styles, one one-pager

Every style builds the same static portfolio page — hero, work-grid with hover video, showreel, contact. Pick a style, fill in your brand.

Hero
Work-grid · hover video
Showreel
Contact

All previews show fictional brands. The Cinematic style is modelled on a cinematic studio site; every user fills in their own brand, work and imagery.

Also: your own deck system

Four styles, one content

See the add-ons

The same content, set differently each time. The deck skill builds decks, documents and PowerPoints in your system. Available separately as an add-on.

Choose your style once. From then on, every deck and document is formatted directly in that style — consistent, no reformatting each time.
