/lint

Run all project linters and report a unified summary.

Linters

Tool	Scope	What it checks
ruff check	src/ scripts/ tests/	Python lint (E, F, I, UP)
ruff format --check	src/ scripts/ tests/	Python formatting
mypy	src/	Python type checking
sqlfluff lint	dbt/models/ dbt/tests/	SQL style & conventions

Steps

1. Parse argument (optional)

   • python → run only ruff + mypy
   • sql → run only sqlfluff
   • all or no argument → run everything

2. Run selected linters — run all applicable commands in parallel:

   Python linting (ruff check):

   uv run ruff check src/ scripts/ tests/
   

   Python formatting (ruff format):

   uv run ruff format --check src/ scripts/ tests/
   

   Python types (mypy):

   uv run mypy src/
   

   SQL linting (sqlfluff):

   uv run sqlfluff lint dbt/models/ dbt/tests/ --config dbt/.sqlfluff
   

3. Auto-fix — if ruff or sqlfluff report fixable violations, ask the user:

   "N fixable violations found. Apply auto-fix?"

   If yes:

   uv run ruff check --fix src/ scripts/ tests/
   uv run ruff format src/ scripts/ tests/
   uv run sqlfluff fix dbt/models/ dbt/tests/ --config dbt/.sqlfluff
   

4. Report summary — print a table like:

   Linter          Status   Issues
   ruff check      PASS     0
   ruff format     FAIL     3 files
   mypy            PASS     0
   sqlfluff        PASS     0
   

   Use PASS/FAIL per linter. If all pass, end with: All linters passed.
