 **BUG INVESTIGATION**: When investigating whether a bug was already resolved in a previous version, always prioritize searching through `docs/source/about/changelog.rst` first before using Git history. Only search through Git history when no relevant changelog entries are found.
 
+**CODE RETRIEVAL**: Always prioritize using Serena tools (e.g., `mcp_oraios_serena_find_symbol`, `mcp_oraios_serena_search_for_pattern`) for code retrieval and analysis over standard file reading or searching tools.

-- `lint-python` -- Python linting and type checking via `hatch fmt --check` and `hatch run python:type_check`

 Always ensure your changes pass local validation before pushing, as the CI pipeline will run the same checks.
 
 ## Important Notes
 
-- **This is a Python-to-JavaScript bridge library**, not a traditional web framework - it enables React-like components in Python
-- **Component rendering uses VDOM** - components return virtual DOM objects that get serialized to JavaScript
-- **All builds and tests run quickly** - if something takes more than 60 seconds, investigate the issue
-- **Hatch environments provide full isolation** - no need to manage virtual environments manually  
-- **JavaScript packages are bundled into Python** - the build process combines JS and Python into a single distribution
-- **Browser automation tests may fail in headless environments** - this is expected behavior for Playwright tests
-- **Documentation updates are required** when making changes to Python source code
-- **Always update this file** when making changes to the development workflow, build process, or repository structure
-- **All tests must always pass** - failures are never expected or allowed in a healthy development environment
