Individual skill
importer-scaffolder
Use when asked to build an importer from a competitor's export, migrate users' data from another tool, map a CSV or JSON export onto my data model, or make switching to my project easy. Given a sample export (CSV or JSON), produces a field mapping table, an importer code skeleton, a rule that unmatched records are kept rather than dropped, and test fixtures including the awkward cases. For a database migration inside one system, use database-migration-plan.

# Importer Scaffolder
People switch tools when leaving costs them nothing, and an importer is how a small project removes that cost. Importers fail quietly: a column is renamed, a date is in another format, a record has no match, and data disappears without anyone noticing. This skill builds an importer from a real sample export, with a mapping that is explicit and a rule that nothing is silently dropped.
## Required Inputs
Ask for these if not provided:
- **A sample export**: a few rows of CSV or a JSON excerpt, with any personal data replaced
- **The source tool** and how users produce the export
- **Your data model**: the target fields, types and required fields
- **Your language and stack** for the importer
- **Where unmatched data should go**: a notes field, an extras column, or a separate file
