Validate widget definition files. Use when the user asks to "run the widget check", "check my widget", or "validate a widget".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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.Read the whole file at its exact version.
How to install
mdr add yaniv-golan/skill-creator-plus/widget-check@sha256:a78d749cf137d89dThe line at the top of this page pins the label git:20260830.280f6e8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
