Red Flags - STOP

Never:

Assume expertise from surface reading
Skip primary sources for summaries only
Ignore domain experts' warnings
Apply patterns without understanding context
Trust outdated sources for evolving domains

Always:

Validate understanding through application
Seek multiple perspectives
Document gaps in knowledge
Update knowledge base as you learn
Cite sources for important claims
