Purpose: guidance for agentic edits in asteroidpy.

Build / Lint / Test Commands

• python -m build to build artifacts.
• pytest -q to run the test suite.
• pytest <path>::<test_name> -q for a single test.
• ruff check . (or flake8) for linting; mypy for type checks.

Code Style

• Imports: standard library first, then third‑party, then local; explicit imports only.
• Formatting: format with Black; sort imports with isort; auto‑format on save if available.
• Types & Naming: use type hints; snake_case for functions/vars; CamelCase for classes.
• Errors: avoid bare excepts; raise/propagate clear exceptions; validate inputs early.
• Tests: tests should be small, isolated; prefer parameterized tests when sensible.
