.pre-commit-config.yaml

---
# Single source of truth for Opik's pre-commit checks across the monorepo.
# Each scope is gated by `files:` so a commit only runs the hooks for the paths
# it touches. Local commits and the unified lint CI workflow both drive off this.
#
# Versions of remote linters are pinned per `rev:` (the framework's design — it
# provisions each tool in an isolated env so contributors need no Python/JS/Java
# install to run the Python hooks). Keep them fresh with `pre-commit autoupdate`.
