The screenshot is real output from the kit’s own commands. Tested from a fresh download of this exact zip: ./run_tests.sh passed on Python 3.13 and 3.10.
This folder is a plugin marketplace (.claude-plugin/marketplace.json). In Claude Code: /plugin marketplace add ./product-feed-checker-bundle, then install the tools you want from it. Or copy any plugins/<tool>/skills/* folder into your agent's skills folder.
./run_tests.sh runs every tool's tests (Python 3.9+, no dependencies, offline). ./demo.sh shows the first lines of each demo.
They check files, not your store, landing pages, images or each platform's policy review, so a clean report doesn't guarantee approval.
