+## Linting and Tidying
+
+Use the `api-dev` Docker service to run [precious](https://github.com/houseabsolute/precious) for linting and tidying. Use `bin/dc` instead of `docker compose` to ensure git worktrees are handled correctly.
+
+```sh
+# tidy all files
+bin/dc run --rm api-dev precious tidy --all
+
+# lint all files
+bin/dc run --rm api-dev precious lint --all
+
+# lint only files changed since a branch
+bin/dc run --rm api-dev precious lint --git-diff-from origin/master
+```
