add-block

Create a new Gutenberg block following WordPress best practices.

Pre-flight: Variation check

Before scaffolding a new block, run this check:

1. Search existing blocks (src/blocks/*) for anything conceptually similar.
2. Ask: would the new block differ from an existing one only by 1–3 attributes and share the same save() output structure?
3. If yes → register a variation via registerBlockVariation, not a new block. Variations have no migration cost and no deprecation debt.
4. If the save markup or inner-block structure actually differs → a new block is justified. Proceed.

See the "Variations vs. new blocks" section in .claude/claude.md for rationale and the consolidation pattern for sibling blocks.
