Claude Code's "extended thinking" is a summary- not authentic thinking

Claude's 'extended thinking' feature does not provide access to authentic AI reasoning—Anthropic encrypts the actual reasoning blocks and only returns a summary, with full access requiring enterprise agreements. This creates significant compliance and audit trail risks for organizations deploying Claude-based agents, as IT leaders cannot obtain verifiable records of the actual logic driving automated decisions. The opaque documentation and data loss inherent in the summarization process should be carefully evaluated before committing to Claude for mission-critical applications requiring explainability and accountability.
