What does this skill do?

The Flujo MLE Production Skill transforms modeling work into robust, auditable, and deployable machine learning pipelines. It defines clear data contracts, ensures reproducible training, establishes measurable promotion gates, and plans deployment, monitoring, and rollback in an explicit and auditable manner.

From Notebook to Pipeline
Convert notebook code into a reusable training, evaluation, and inference pipeline with typed configurations and fixed seeds.
Promotional Doors
Define key metrics, latency and cost guardrails, and no-deploy thresholds before training the model.
Troubleshooting Drift and Leaks
Diagnose issues caused by data drift, label leakage, obsolete features, or inconsistencies between training and serving.
Deployment and Rollback
It packages artifacts with preprocessing, validates input/output schemas, and defines an explicit rollback plan with operational monitoring.

Usage examples

🔄 From notebook to pipeline
I have a training notebook for a classifier. Help me turn it into a reproducible pipeline with typed configuration and a fixed seed.
📊 Promotional Doors
Define promotion thresholds for my ranking model: minimum AUC of 0.82, maximum calibration error of 0.04, and p95 latency below 80 ms.
🔍 Debug drift
My production model's performance has declined. Help me diagnose whether there is feature drift, label leakage, or inconsistencies between training and serving.
🚀 Deployment Plan
Design a canary deployment plan with shadow traffic, post-deployment checks, and an explicit rollback plan for my recommender system.

Features

Explicit Data Contracts Define the entity granularity, label, availability delay, point-in-time join rules, and split policy before training.
Reproducible Training Immutable typed configurations, fixed seeds, dependency versioning, and artifact hashes that eliminate hidden state in notebooks.
Measurable Quality Doors Fail-closed deployment: If a metric is missing or does not meet the threshold, the model is not deployed. Latency, cost, and calibration guardrails.
Complete Drop-Down Artifacts Bundle the version, data reference, configuration, and preprocessing together with the model, including schema validation and fallback.
Monitoring and Rollback Monitor feature and prediction drift, the health of delayed labels, and business KPIs with an explicit rollback plan.

Frequently asked questions

For any production ML system: classifiers, recommendation systems, ranking, forecasting, embeddings, or anomaly detection.
No. The skill generates text and code artifacts (contracts, configurations, promotion gates, plans) that you integrate into your existing MLOps stack.
Through immutable, typed configurations, fixed seeds, dependency versioning, and an artifact hash that combines the dataset, code, and configuration.
The gates fail in a closed state: if a metric is missing or does not meet the configured threshold, the model is not promoted to production.
