What problem does it solve?
It eliminates the slow, error-prone cycle of reviewing code by helping you systematically find and fix issues across security, performance, correctness, readability, maintainability, and testing.
Core Features & Use Cases
- Multi-dimension review with fixes: Detects prioritized issues across six quality dimensions and applies concrete improvements, not just commentary.
- Iterative hardening cycles: Runs one or more improvement passes that raise the severity bar over time to converge toward a cleaner codebase.
- Consolidated, mergeable repair workflow: Uses parallel worktree-isolated fix branches and a consolidation step to merge changes safely.
- Use case: Before releasing or after receiving a bug report, run this to harden an existing codebase by addressing critical security/correctness problems first, then improving performance, structure, and test coverage.
Quick Start
Run /improve 2 to perform two iterative improvement cycles and automatically apply fixes with verification and final committing.
