The real cost
Every cold start steals time you'll never get back.
- You re-explain your stack, tone, and "never do this" list — again and again.
- Generic outputs mean another editing pass you didn't plan for.
- Custom instructions drift: too short to capture you, too vague to enforce.
How it works
02
Answer 20 deep questions
Each question builds on your last answer. AI pushes back on vague replies and pulls real examples.
03
Get your skill file
We compile a structured .md with hard rules, voice samples, and an examples bank Claude can follow.
A generic prompt gets you generic work.
Most people describe their job title. CustomSkill hunts what's individual — the rules you'd put in a CLAUDE.md, the phrases you'd never write, the PR feedback you always give.
Twenty questions, each personalized from your last answer. Then we compile an 8-section Markdown skill file Claude can treat as operating instructions.
Before & after
What changes when Claude has your skill file
Without CustomSkill
- Starts cold every session
- "Clean code" advice that fits anyone
- You edit tone, format, and rules manually
- Context lost when you switch chats
With your skill file
- Your stack, voice, and bars upfront
- Imperatives: "Never…" / "Always…"
- Examples bank matched, not paraphrased
- Reusable across Claude surfaces
Why it pays for itself
Twenty-five minutes beats hundreds of micro-corrections
Ship faster with less rework
Stop re-pasting stack, tone, and rules every session. Claude starts aligned on your standards from message one.
Outputs that sound like you
Hard rules and real samples — not "professional and concise." Your voice, your pet peeves, your bar for done.
One file, every workflow
Use the same skill in Claude.ai, Cowork, or API projects. Build multiple roles without files fighting each other.

FAQ
Questions before you start
How is this different from a custom GPT or Project instructions?
Those are short and easy to keep generic. CustomSkill runs a 20-question interview designed to reject answers that could describe anyone in your field — then compiles a full skill file with hard rules, anti-patterns, and verbatim examples.
Do I need to be technical?
No. You answer in plain English. The interview switches between quick multiple-choice and open text when it needs a real sample from you.
How long does it take?
Most people finish in about 25 minutes. You can pause and resume — progress is saved automatically.
Is my data private?
Your interview answers are used only to generate your skill file. We don't train models on your content. Sessions are deleted after delivery.
What if I'm not happy with the file?
14-day satisfaction guarantee — email us and we'll make it right with a refund or a re-run.
Can I buy more than one role?
Yes. Each role is a separate interview and skill file. They're designed not to clash when you use them in different contexts.
