What it does

Mlnet is an agent skill from managedcode/dotnet-skills. Use ML.NET to train, evaluate, or integrate machine-learning models into .NET applications with realistic data preparation, inference, and deployment expectations. USE FOR: ML.NET integration; local model training or retraining; inference pipelines, model loading, evaluation, and deployment review. DO NOT USE FOR: unrelated stacks; generic tasks that do not need this specific guidance. INVOKES: inspect the repository context, edit targeted files, and run relevant build, test, lint, or validation commands when…

Its SKILL.md is about 560 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `manifest.json`, `references/examples.md` and `references/patterns.md`). Compatibility notes: Requires ML.NET, Model Builder, or ML.NET CLI scenarios.

It sits in Data & Analytics, covering Machine learning, Fine-tuning and Codebase knowledge for agents. It works with .NET. The repository describes itself as: Installable .NET skill catalog and CLI for Codex, Claude Code, GitHub Copilot, and Gemini. The licence is MIT.

When your agent uses it

  • : ML.NET integration
  • Local model training
  • Inference pipelines
  • Deployment review

Example prompts

  • “/mlnet”

Requirements

  • Compatibility (from SKILL.md): Requires ML.NET, Model Builder, or ML.NET CLI scenarios.

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  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…
  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.

What it can do on your machine

Read from SKILL.md and the folder at commit 535dd55. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Requires ML.NET, Model Builder, or ML.NET CLI scenarios.

    From compatibility in the SKILL.md frontmatter.

Context cost

Mlnet loads about 559 tokens when it runs, and up to ~13k if it reads all its reference files. Until then it costs about 135 tokens; SKILL.md has 199 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~135
When it runs · the whole SKILL.md, loaded when a task matches
~559
With references · SKILL.md plus every file in references/, read only if the agent opens them
~13k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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

Questions about Mlnet

What does Mlnet do?

Use ML.NET to train, evaluate, or integrate machine-learning models into .NET applications with realistic data preparation, inference, and deployment expectations. Mlnet is an agent skill from managedcode/dotnet-skills.NET applications with realistic data preparation, inference, and deployment expectations.

When should I use Mlnet?

Mlnet fits situations like: : ML.NET integration; local model training; inference pipelines; deployment review.

How do I install Mlnet in Claude Code?

Run `npx skills add managedcode/dotnet-skills --skill mlnet -a claude-code`. Or copy the skill folder (catalog/Frameworks/ML.NET/skills/mlnet in managedcode/dotnet-skills) into .claude/skills/mlnet in your project. Claude Code loads it when a task matches its description.

How do I install Mlnet in Codex?

Run `npx skills add managedcode/dotnet-skills --skill mlnet -a codex`. Or copy the skill folder (catalog/Frameworks/ML.NET/skills/mlnet in managedcode/dotnet-skills) into .agents/skills/mlnet in your project. Codex loads it when a task matches its description.

Can I use Mlnet in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add managedcode/dotnet-skills --skill mlnet -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/mlnet, .gemini/skills/mlnet, .github/skills/mlnet and .opencode/skills/mlnet in your project.

What does Mlnet need to run?

SKILL.md names no scripts, command-line tools or credentials: Mlnet is instructions for the agent only. Compatibility (from SKILL.md): Requires ML.NET, Model Builder, or ML.NET CLI scenarios..

Does Mlnet access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Mlnet safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Mlnet use?

Mlnet is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Mlnet use?

About 559 tokens (SKILL.md is roughly 2.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 12k tokens, read only when the agent opens those files.

What are the alternatives to Mlnet?
