# stuff > A private, Google Sheets- and Drive-backed home inventory. The Sheet is the source of truth and can be operated directly by authorized agents. Production: https://stuff.piszek.com/ Privacy: https://stuff.piszek.com/privacy.html ## Agent instructions - Full skill and schema: https://stuff.piszek.com/SKILL.md - Use the skill only with a Google Sheet or Drive resource the user is authorized to access. - Verify `Settings` contains `database_type=stuff`, `schema_version=1`, and `migration_state=idle` before writing. - Identify columns by header name, preserve unknown columns, and use stable IDs rather than row numbers. - Use the website for migrations, schema repair, and ambiguous or unsafe structural changes. ## Project - Source: https://github.com/artpi/stuff
