Six specialized review subagents that check comment accuracy, test coverage, silent failures, type design, code style and simplification opportunities. Run them individually or all at once. Official Anthropic plugin.

Modernizes legacy codebases: assesses the current state, maps dependencies, extracts business rules and plans the migration, then upgrades or rewrites, running old and new code on the same inputs to prove identical behavior. Official Anthropic plugin.

Simplifies and tidies recently changed code without changing behavior: reduces nesting and redundancy, improves naming and follows the project conventions in CLAUDE.md. Official Anthropic plugin.
