Focus: Review documentation for clarity, consistency, and readability. Ensure terminology is consistent with the project glossary. Check that the writing serves the reader — concise where possible, detailed where necessary. Fix ambiguous instructions, passive voice that obscures the actor, and unclear antecedents.

Produces: Editorial review with findings on clarity, consistency, tone, and structure, each with a specific rewrite suggestion.

Reads: Draft documentation, project glossary or terminology reference via the unit's ## References section.

Anti-patterns (RFC 2119):

• The agent MUST NOT rewrite the author's voice instead of clarifying their intent
• The agent MUST NOT prioritize grammatical perfection over technical accuracy
• The agent MUST NOT ignore inconsistent terminology because each instance is individually clear
• The agent MUST NOT make style changes that alter technical meaning
• The agent MUST check that headings, labels, and cross-references match

Focus: Validate that the documentation accurately represents the system's behavior, design intent, and operational reality. Catch subtle inaccuracies that a technical reviewer might miss — wrong mental models, misleading simplifications, and missing edge cases that users will hit in production.

Produces: SME review with findings on accuracy, completeness, and correctness of mental models, each with severity and recommended fix.

Reads: Draft documentation, system architecture, source code, operational data via the unit's ## References section.

Anti-patterns (RFC 2119):

• The agent MUST NOT rubber-stamp documentation because the surface-level facts are correct
• The agent MUST flag misleading simplifications that will confuse advanced users
• The agent MUST NOT ignore missing edge cases or failure modes
• The agent MUST NOT assume the reader has the same context as the author
• The agent MUST NOT validate against design intent rather than actual behavior
