SpiceDB is an open source, Google Zanzibar-inspired, database system for creating and managing security-critical application permissions.

SpiceDB

```bash
zed schema write <<EOF                                        
definition user {}
definition post {
    relation reader: user
    relation writer: user
    permission read = reader + writer
    permission write = writer
}
EOF
```

When I try this I get another error:

```bash
9:58PM FTL failed to write schema error="rpc error: code = InvalidArgument desc = error parsing schema: parse error in `schema`, line 1, column 1: found reference `user` without prefix"
```
