## What it does

The plugin structures machine learning workflows across standard Python libraries including scikit-learn, skrub, skore, pandas, and polars. Rather than writing ad-hoc scripts, the agent follows explicit phases: setting up project layout, framing the problem, generating pipeline steps, and persisting evaluation artifacts.

The system separates actions into distinct skills such as `model-ml-pipeline`, `explore-ml-data`, and `smoke-test-ml-pipeline`. The modeling skill strictly demands a locked problem framing before allowing model code generation. Verification runs structural pytest checks to ensure prediction counts match the test grid. Experiment summaries can sync between local files, Skore Hub, or MLflow.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install probabl-skills@claude-community
```

## When to use it
- Scaffold a standard ML repository layout
- Build a data pipeline with skrub and scikit-learn
- Run structural smoke tests on model predictions
- Export and sync experiment audit reports with Skore Hub

## Example prompts
- Given the context in `data/README.md` and files in `data/`, build a baseline ML pipeline for our next experiments.
- Audit the saved skore report and extract candidate ideas into the backlog.
- Run a smoke test on the trained pipeline using pytest.

# Probabl Skills

A set of skills to steer your AI-assisted machine learning experiments.
The skills help you:

- build your machine learning pipeline with core data science libraries
  (e.g. scikit-learn, skrub, skore, pandas, polars) while ensuring
  your agent follows correct methodologies
- evaluate and store your results so you can easily audit and get insights from them
- connect your agent to [Skore Hub](https://skore.probabl.ai/) to get a comprehensive view of
  your experiments and results
- iterate on your next experiments from a Skore audit digest (a
  separate backlog turn) and from your own feedback
- organize your workspace according to best practices for data science projects
  (e.g. cookiecutter template)

Probabl skills let you focus on the science while AI agents handle the implementation,
guided by two important ingredients: core data science libraries for maintainability  and
methodological best practices for running your machine learning experiments properly.

In practice, from a prompt such as:

```text
╭────────────────────────────────────────────────────────────────────────╮
│ > Given the context in the file `data/README.md` and the data located  │
│   in `data/`, let's build a first machine learning pipeline that will  │
│   serve as baseline for the next experiments that we are going to run  │
│   together.                                                            │
╰────────────────────────────────────────────────────────────────────────╯
```

you can expect your agent to start experimenting with you. The skills work well with
models such as Claude Opus and Sonnet and produce great results with smaller models such
as Qwen 3.7 Flash or DeepSeek v4.1 Flash. Each skill declares `metadata.modelTier`
(`small`, `medium`, or `big`). The eval maps those tiers to Qwen3.8 27B,
DeepSeek v4.1 Flash, and Qwen3.8 Max. A skill may also declare `metadata.role`
(`entry` or `helper`) when its caller continues after it loads. A helper runs on at
most its caller's tier, so a skill never loads a helper of a higher tier;
`tools/validate_catalog.py` enforces it.

As for agent harnesses, we tested them with Claude Code, OpenCode, Cursor, and GitHub
Copilot and found no significant difference in terms of skill invocation.

## Install

The skills installer is the `skore` command, included in the [`skore`](https://github.com/probabl-ai/skore)
package on PyPI and conda-forge.

```bash
# with pip
pip install skore
# with uv
uv tool install skore
# with pixi
pixi global install skore
# with conda
conda install conda-forge::skore
```

`skore skills install` with no arguments opens a picker for the source, the
skills, the agent, and the project or user directory. Without a terminal, that
same command prints the catalog.

Install a workflow pack by id when you do not need every skill:

```bash
skore skills install setup  # workspace, environment, git, export
skore skills install data_analysis  # data exploration
skore skills install model  # frame, build, smoke-test, evaluate, audit
skore skills install loop   # triage, explore, model, review, backlog, export
skore skills install export  # notebooks and documentation site
```

`skore skills install ml-experimentation` and `skore skills install all`
(or `--all`) install every skill in the catalog.

You can use `uvx` or `pixi exec` to install `skore` and run the installer in
an isolated environment:

```bash
uvx --from skore skore skills install
```

or

```bash
pixi exec --spec skore skore skills install
```

If you prefer `npx`, then you can use:

```bash
npx skills add probabl-ai/skore-skills
```
