## For Software Engineers

### 1\. Code Review Agent

**Difficulty**: Medium | **Impact**: Very High

Automates the mechanical parts of code review so humans can focus on design and logic.

| Attribute | Details |
| --- | --- |
| Skills | `check-security`, `check-standards`, `check-performance`, `check-accessibility` |
| Platforms | Claude Code, Copilot, Cursor |
| MCP dependencies | None (filesystem only) |
| Key value | Catches 70% of review comments automatically, freeing reviewers for design-level feedback |

**Why it works**: Code review is the highest-leverage activity for quality, and also the most tedious. Automating the checklist frees humans for the hard parts.
