Naming rules

Tables and columns

Table and column names must:

In addition:

Table names can’t start with proj_. The prefix is reserved.
Column names can’t be id or created_at. Every table already has them.
Names are unique within their scope: one table name per project, one column name per table.

The rule as a regular expression:

^[a-z_][a-z0-9_]{0,62}$

When you describe columns in plain language, Claude converts names for you. “Last contacted” becomes last_contacted.

Field	Rule
Name	1 to 80 characters. Any characters are allowed. Leading and trailing spaces are trimmed, and repeated spaces are collapsed.
Description	Optional, up to 200 characters, with the same space handling

Project names don’t have to be unique. Tools identify projects by id.

Workspace names are 1 to 80 characters, with the same space handling as project names.
