policyengine-standards

Code quality standards enforce consistent formatting, testing, and CI checks across repositories. This Skill applies PolicyEngine's development standards—Python 3.13 with `uv run`, Black for formatting, Prettier for JavaScript, and pytest for testing—automatically before commits and during PR reviews to prevent CI failures.

Use Black through this Skill to format all Python files in your current directory. The Skill integrates with your git workflow, applying formatting standards automatically and ensuring consistent code style across your repository before you push changes.

Test-driven development writes tests first to prevent regressions and build confidence in refactoring. This Skill promotes TDD practices with pytest, requires all tests to pass before marking PRs ready, and automates CI validation through the `/create-pr` command that waits for checks to complete.

Yes. This Skill applies during new repository setup, enforcing Python 3.13, `uv run` for commands, Jupyter Book 2.0 with MyST-NB for documentation, Black formatting, Prettier for JavaScript, and pytest testing from the start to maintain consistent standards.

AI-generated code often has file versioning issues and unformatted commits. This Skill standardizes AI-generated code by applying Black, Prettier, and test requirements, catching these pitfalls during PR review so they don't reach CI and cause delays.

Yes. This Skill requires uv, Black, Prettier, pytest, npm, and gh. These tools handle Python formatting, JavaScript formatting, testing, and GitHub PR automation. All dependencies must be available in your environment to enforce standards across the full workflow.
