Claude Code /simplify Deploys Four Agents to Automate Code Review and Optimization

Anthropic has enhanced Claude Code's /simplify command to launch four parallel agents that automatically review, optimize, and refactor code in a single operation. The command, which invokes an updated code-review process, deploys specialized agents to audit code simultaneously for CLAUDE.md compliance violations, identify obvious bugs, discover duplicated logic and reuse opportunities, remove unnecessary complexity, optimize performance, and analyze historical context via git blame. Each agent operates independently on the same codebase changes, then aggregates findings to suggest and apply targeted fixes.
