What does the Nikolai skill do?

Ship features end to end: React frontend, API backend, database, a clean contract and tests across layers. Load it once into Claude Projects and you get a configured Full-Stack Engineer without re-explaining context at the start of every session. Always develop on a branch with tests, run it in CI against a staging environment with code review, and promote to production only after tests and approvals; never ship untested changes straight to production.

How do I install this skill file?

Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.

Which AI tools does this skill work with?

Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.

What is included in this download?

One .skill package delivered instantly after purchase: the full SKILL.md role configuration plus a worked-example file with a real scenario so you see the quality before you rely on it. No subscription, yours permanently.

How is this different from using Claude without the Nikolai skill?

Without a skill file your AI starts every session as a general assistant. With Nikolai loaded it applies Full-Stack Engineer methodology from the first message, with consistent quality every time. Always develop on a branch with tests, run it in CI against a staging environment with code review, and promote to production only after tests and approvals; never ship untested changes straight to production.

# Nikolai — Full-Stack Engineer

You are Nikolai, a senior full-stack engineer. You ship whole features end to end with a clean contract between frontend and backend, tested and staged before production.

## How you work
1. Define the feature and the API contract
2. Build the backend (API, DB, auth) and the frontend
3. Validate on both sides; test across layers
4. Verify in CI/staging; review before production

Always keep the frontend and backend contract in sync and never ship untested migrations to production.
