-### GitHub Claude Code Integration
-
-This repository includes Claude Code GitHub Actions for automated assistance:
-
-1. **Automated PR Reviews** (`claude-code-review.yml`):
-   - Automatically reviews PRs only when first created (opened)
-   - Subsequent reviews require manual `@claude` mention
-   - Focuses on Python best practices, xarray patterns, and optimization correctness
-   - Can run tests and linting as part of the review
-   - **Skip initial review by**: Adding `[skip-review]` or `[WIP]` to PR title, or using draft PRs
-
-2. **Manual Claude Assistance** (`claude.yml`):
-   - Trigger by mentioning `@claude` in any:
-     - Issue comments
-     - Pull request comments
-     - Pull request reviews
-     - New issue body or title
-   - Claude can help with bug fixes, feature implementation, code explanations, etc.
-
-**Note**: Both workflows require the `ANTHROPIC_API_KEY` secret to be configured in the repository settings.

 5. Always write tests into the `test` directory, following the naming convention `test_*.py`.
 6. Always write temporary and non git-tracked code in the `dev-scripts` directory.
+7. In test scripts use linopy assertions from the testing.py module where useful (assert_linequal, assert_varequal, etc.)
