Compare code with documentation
Read DDD and apply Compare the actual result, using its inspection/research steps to find the existing task note and refresh missing or stale context. That skill owns the procedure and persistent-note rules.
For review-only work, report findings without editing application code. For an authorized fix, research unexplained discrepancies, correct them, and rerun checks. Save the comparison and actual results in the same note, naming its path. Relevant mismatches or unsupported consequential assumptions prevent a clean completion claim. No assurance case or CLI verdict is required.
Consult citation comparison or execution checks when needed.
