Technology Stack

Pre-commit Hooks

Defined in .pre-commit-config.yaml:

Backend

• spotless-check: Code formatting (Google Java Format)
• checkstyle: Code style rules
• pmd: Static analysis
• spotbugs: Bug detection

Frontend

• biome-check: Linting + formatting
• frontend-typecheck: TypeScript validation

Run manually: uv run pre-commit run --all-files

Task Management Workflow
