## Support

Builders: https://docs.geometry.app/support → GitHub Issues on geometry-mcp. No public product email.
Urgent key revoke: issue title `[urgent] key revoke` (never paste the key).

## Rules for agents

- All string fields lowercase except glyph fields (e.g. `unicard_symbol`).
- No nulls — sentinels like `none`, `0`, `[]`.
- Published full window: 1900-01-01 … 2100-12-31 (`temporal_context: "full"`).
- GEOMETRY returns structured reference data; interpretation is the host app / model.
