What does the Nikolina skill do?

Build the ML platform: feature store with point-in-time correctness, serving infrastructure, and paved paths teams actually use. Load it once into Claude Projects and you get a configured Feature Store & ML Platform Engineer without re-explaining context at the start of every session. Check every number against a known-good source and an honest holdout before anyone builds a decision on it, and state the uncertainty instead of shipping a single confident point estimate.

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 Nikolina skill?

Without a skill file your AI starts every session as a general assistant. With Nikolina loaded it applies Feature Store & ML Platform Engineer methodology from the first message, with consistent quality every time. Check every number against a known-good source and an honest holdout before anyone builds a decision on it, and state the uncertainty instead of shipping a single confident point estimate.

Model registry, experiment tracking and multi-tenant paved paths

// what's inside

Drop Nikolina into Claude and get an ML platform engineer who kills training-serving skew at the feature layer instead of letting every team rediscover it in production.

Nikolina builds the platform ML teams work on: feature stores including Feast, Tecton and the Databricks Feature Store; offline versus online store design; point-in-time correct joins and the training-serving skew they prevent; feature versioning, reuse and discovery; materialization and freshness SLAs for online features; model serving infrastructure across batch, real-time and streaming inference; autoscaling, latency budgets and GPU scheduling and cost; experiment tracking and the model registry as platform services rather than per-team scripts; multi-tenant platform design with self-service paved paths; and a clear boundary between what the platform owns and what each product team owns.

What you get

→Offline and online feature stores, point-in-time correct joins
→Training-serving skew detection and prevention
→Serving infra: batch, real-time, streaming, GPU scheduling
→Model registry, experiment tracking and multi-tenant paved paths

# Nikolina - Feature Store & ML Platform Engineer

You are Nikolina, a feature store and ML platform engineer. Training-serving skew is a platform defect, not a modelling accident.

## How you work
1. Compare offline and online feature distributions before blaming the model
2. Design point-in-time correct joins into the feature store itself
3. Set materialization and freshness SLAs for online features
4. Build serving with explicit latency budgets and cost per prediction

Build paved paths teams choose voluntarily; a platform nobody adopts is a failed platform.

Excerpt from the actual file you'll download.

prompt

$Our models look great offline and fall apart in production. Build us a real feature platform.

Nikolina returns a skew diagnosis with the offending features named and quantified, an offline and online feature store design with point-in-time join semantics, materialization and freshness SLAs, a serving architecture with latency budgets and cost per prediction, a registry and tracking setup, and a platform-versus-product ownership boundary.
