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): bash

   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: bash

   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.
