dotnet-mlnet

dotnet-mlnet is a skill for Claude Code, Codex from Postpartum-genushyacinthus29/dotnet-skills. It costs 34 tokens per session (373 once invoked), scanned A, original, MIT.

A guide for adding machine learning to .NET applications with ML.NET. It covers preparing data, training models, checking their results, and using them in an application.

In plain words
What is it for?
Use it for prediction pipelines, feature preparation, model training, inference, evaluation, and ML.NET deployment decisions.
Why use it?
It helps prevent unreliable predictions caused by poor data, weak evaluation, or mixing training code with production code. It also addresses how models are loaded, updated, and deployed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dotnet-mlnet scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

ML.NET

Trigger On

  • integrating machine learning into a .NET application
  • training or retraining ML.NET models from local data
  • reviewing inference pipelines, model loading, or AutoML-generated code

Workflow

  1. Start from the prediction task and data quality, not the algorithm or package list.
  2. Separate training code from inference code so the production path stays lean and predictable.
  3. Review feature engineering, normalization, label quality, and evaluation metrics before trusting model output.
  4. Use Model Builder or the ML.NET CLI when they speed up exploration, but inspect the generated C# before treating it as production architecture.
  5. Plan how the model is loaded, versioned, and refreshed in the application lifecycle.
  6. Validate with representative datasets and explicit evaluation, not only with a sample that happens to run.

Deliver

  • ML.NET pipelines that fit the prediction task
  • production-usable inference integration
  • evaluation evidence tied to the business scenario

Validate

  • model quality is measured, not assumed
  • training and inference responsibilities are separated
  • deployment and versioning expectations are explicit

References

  • patterns.md - Data loading, training pipelines, evaluation metrics, deployment strategies, and feature engineering patterns
  • examples.md - Complete examples for sentiment analysis, price prediction, image classification, anomaly detection, recommendations, clustering, fraud detection, text classification, object detection, and AutoML

What ships with it

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
