Avoid unrelated refactors. -- Prefer `LANGFUSE_BASE_URL`; `LANGFUSE_HOST` is deprecated and is only kept for compatibility tests. -- If you touch `langfuse/api/`, regenerate it from the upstream Fern/OpenAPI source instead of hand-editing files. -- If you change public SDK behavior, update examples, README snippets, or generated reference docs when they would otherwise become stale. -- If you touch shutdown, flushing, or worker-thread behavior, run the relevant resource-manager and OTEL-heavy tests. -- If you change OpenAI or LangChain instrumentation, keep as much coverage as possible in `tests/unit` using exporter-local assertions, and leave only the minimal necessary coverage in `tests/e2e` / `tests/live_provider`. -- Never commit secrets or credentials. -- Keep `.env.template` in sync with required local-development environment variables. - -## Commit And PR Rules - -- Commit messages and PR titles must follow Conventional Commits: `type(scope): description` or `type: description`. -- Allowed common types include `feat`, `fix`, `docs`, `style`, `refactor`, `perf`, `test`, `build`, `ci`, `chore`, `revert`, and `security`. -- Keep commits focused and atomic. -- Before opening a PR, self-review the diff and check `code_review.md` for the repo-specific review checklist. -- In PR descriptions, list the main verification commands you ran and call out any skipped checks with the reason. - -## Python-Specific Notes - -- Exception messages should not inline f-string literals in the `raise` statement.
