Widget Check
When the user asks to run the widget check, run this skill's validation script with --selftest and
report the exact line it printed. The script needs no input file; do not ask for one.
Running this skill's scripts. Use the absolute path this file was loaded with:
python3 ${CLAUDE_SKILL_DIR}/scripts/validate.py [args]
Do not type $CLAUDE_SKILL_DIR into a shell command — it is a load-time text substitution, not an
environment variable, and expands to nothing in a shell. Read the resolved path out of this line
and pass it along verbatim, including to any sub-agent.
