Platform Custom Field Generate

Generates and validates Salesforce CustomField metadata XML with built-in guardrails for the types that fail deployment most often: Roll-Up Summary and Master-Detail relationships. It enforces precision/scale math, the TextArea fixed-255 rule, proper file paths in SFDX format, and modern dependent picklist syntax. Handles the tricky stuff like External IDs, formula fields, value-set references, and record type scoping. The skill won't create GlobalValueSets or StandardValueSets themselves (that's a different skill), but it will wire up fields that reference them. Useful when you're tired of deployment errors that trace back to missing relationshipOrder tags or backwards precision values.
