# Run linter

## When to run

- User asks to run the linter, run lint, or check lint/style.
- After making code changes that should be validated by the project linters.

## What to run

Lint runs **in Docker** via the Makefile; no local Go or Node is required.

From the repo root:

- **Both backend and frontend:** `make lint` (runs golangci-lint then frontend ESLint in Docker).

Uses `docker-compose.tools.yml`; the first run may build the backend-tools and frontend-tools images.

## Scope

- **Backend-only changes** (e.g. `internal/`, `cmd/`): `make lint` still runs both; backend lint runs first.
- **Frontend-only changes** (e.g. `frontend-nuxt/`): `make lint` runs both; frontend lint runs second.
- **Both or unclear**: run `make lint`.

Report pass/fail and any linter errors or file/line references so the user can fix them.
