How does this help me on day 0 with Claude Code?

The generated CLAUDE.md is pre-filled with your Vendor/Module names, your Magento version, your frontend choice, and a hard-rules block that locks Claude into PSR-12, phpcs Magento2, no-vendor-edits, plugins-over-rewrites, db_schema not raw SQL, MFTF + PHPUnit alongside features. The .claude/commands/scaffold-feature.md and .claude/commands/run-tests.md slash-commands are ready to invoke. Open the unzipped folder in claude, type /scaffold-feature, and you’re shipping. Full setup guide here.
