Use for a comprehensive code review of a diff — standalone (a pull request, a SHA range, or the current branch) or as the post-coding review step invoked by ss-coding. Dispatches independent subagents for general code quality, coding-standard compliance (global, stack, and project level, plus OpenSpec compliance when specs are present), and, in post-coding mode with enough scope, a cross-task integration review; then filters by confidence, deduplicates, and produces one consolidated verdict.
