Code Quality Setup

When starting or scaffolding any project, set up formatting, linting, import sorting, type checking, and pre-commit hooks before writing application code. This prevents the painful scenario of adding these tools later and facing thousands of lines of formatting changes in a single commit.

Detect the ecosystem

Determine the project type from existing files or the scaffolding context:

Also check for existing quality tooling configs (.eslintrc, .prettierrc, biome.json, [tool.black] or [tool.ruff] in pyproject.toml, .pre-commit-config.yaml, lefthook.yml). If present, preserve them — only migrate to different tools if the user explicitly requests it (see Guardrails).
