Platform Custom Object Generate

Generates Salesforce Custom Object metadata XML with the right guardrails to prevent deployment failures. It knows when to use ControlledByParent versus ReadWrite sharing models (critical when Master-Detail relationships are involved), picks sensible defaults for name fields (Text for entities, AutoNumber for transactions), and enforces description enrichment whenever you add or change fields or validation rules. The description workflow is smart: it proposes updates and waits for confirmation rather than silently overwriting what might be hand-written documentation. Useful when you're scaffolding custom objects or troubleshooting those cryptic sharing model errors that come back from the Metadata API. The spec is thorough enough that it should catch the common mistakes before you deploy.

When to Use This Skill

Use this skill when you need to:

Create new custom objects
Generate custom object metadata XML
Configure object sharing and security settings
Set up object features and capabilities
Troubleshoot deployment errors related to custom objects
Add, update, or delete a field OR a validation rule on an existing object — any of these may make the object's <description> stale, so you must refresh it (propose + confirm). This applies equally to validation-rule changes, not just fields. See Section 3.B.

For authoritative Metadata API type, field, and enum details beyond this skill, use the platform-metadata-api-context-get skill.

Specification

1. Overview and Purpose

This document defines the mandatory constraints for generating CustomObject metadata XML (.object-meta.xml file). The agent must verify these constraints before outputting XML to prevent Metadata API deployment errors.

File extension: .object-meta.xml
