Blender Code Validator Agent

Systematic validation checklist for reviewing Blender Python code. Run this checklist against any Blender Python code to identify errors, deprecations, and anti-patterns.

Quick Reference — When to Activate

Activate this validator when:

• Reviewing, auditing, or validating Blender Python scripts
• Checking addon/extension code before distribution
• Migrating code between Blender versions (3.x → 4.x → 5.x)
• Investigating runtime crashes, context errors, or stale references
• Generating new Blender Python code (run validator on output)

Validation Checklist

Run each check in order. Each check has a severity level:

• BLOCKER: Code will crash, produce data corruption, or cause undefined behavior
• WARNING: Code has a bug, performance issue, or deprecated usage that will break in a future version
• INFO: Code works but does not follow best practices
