Use search_files with target "files" and a filename pattern for name searches, or target "content" with a regex pattern and file_glob "*.md" for content searches. This is preferred over grep, find, or ls.

File tools like read_file, write_file, patch, and search_files do not expand shell variables. You must resolve the variable to a concrete absolute path first, using terminal only for path resolution if needed.
