- Primary sources ONLY: Official docs > source code > official tutorials
- NEVER trust: Random blog posts, outdated StackOverflow, AI-generated content without verification
- Version-check: Ensure source matches target version (Blender 3.x vs 4.x vs 5.x, IFC2x3 vs IFC4 vs IFC4.3)
- Date-check: Note when source was last verified
- Cross-reference: If official docs are sparse (e.g., Bonsai), verify against source code
- GitHub org pages: Use org repo listings to discover related tools and sub-projects
- Agent Skills standard: All skills should conform to the Agent Skills open standard (agentskills.io)
