Uppercase Converter

Convert English text from lowercase to uppercase using the bundled Python script.

Usage

Run the script to_upper.py in this skill directory. It accepts the text to convert in one of two ways:

1. As command-line arguments (joined with spaces):

   python "$CLAUDE_SKILL_DIR/to_upper.py" "hello world"
   

2. From standard input (when no arguments are given) — useful for piping files or large/multiline text:

   cat input.txt | python "$CLAUDE_SKILL_DIR/to_upper.py"
   

The script prints the uppercased result to stdout. Only ASCII English letters a-z are affected; digits, punctuation, whitespace, and non-English characters pass through unchanged.

Instructions

1. Determine the text the user wants converted.
2. Invoke the Python script using one of the forms above. Prefer stdin for text that contains quotes, newlines, or shell-special characters.
3. Return the script's stdout to the user as the converted result.
4. If the user points to a file, pipe the file into the script via stdin and (if asked) write the output back.
