ruff-format

name	ruff-format
description	Runs project-wise Python formatting with ruff after sourcing train.env for the correct Python path. Use when the user asks to format Python code with ruff, run ruff, or run project-wide formatting.

Ruff format (project-wide)

When to use

Apply this skill when the user wants to:

• Run ruff for Python formatting
• Format project Python code with ruff
• Run project-wise or project-wide formatting

Workflow

1. Source the environment (from repo root). This sets Train_CONDA_PREFIX so ruff and Python come from the holomotion_train conda env.
2. Run ruff using that env’s binary: "$Train_CONDA_PREFIX/bin/ruff".

Format (write changes), from repo root:

source train.env && "$Train_CONDA_PREFIX/bin/ruff" format --config pyproject.toml ./

Format check only (no write), from repo root:

source train.env && "$Train_CONDA_PREFIX/bin/ruff" format --check --config pyproject.toml ./

Rules

• Always source train.env before running ruff.
• Use $Train_CONDA_PREFIX/bin/ruff so the correct env is used.
• Ruff config is in pyproject.toml; from repo root pass --config pyproject.toml and target ./.
