Study src/viterbo/experiments/example_pipeline/ before creating experiments:

src/viterbo/experiments/example_pipeline/
├── SPEC.md           # Research question, method, success criteria
├── stage_build.py    # Stage 1: generate data
├── stage_analyze.py  # Stage 2: compute results
└── stage_plot.py     # Stage 3: create figures

config/example-pipeline/
└── default.json      # Parameters for reproducible runs

data/example-pipeline/
├── synthetic_data.json
└── results.json

tests/test_example_pipeline.py

Run stages:

uv run python -m viterbo.experiments.example_pipeline.stage_build
uv run python -m viterbo.experiments.example_pipeline.stage_analyze
uv run python -m viterbo.experiments.example_pipeline.stage_plot

cd packages/python_viterbo
uv sync --extra dev          # Install dependencies
uv run ruff format .         # Format
uv run ruff check --fix .    # Lint

Code Style

• Docstrings: inputs, outputs, shapes/dtypes
• Pure functions preferred
• Comments explain WHY, not WHAT
