How to Use This Guide
Each recipe includes:
What it does: the problem it solves
Who it's for: the target persona
Skills needed: what to build
Platforms: where it should work
Difficulty: how hard it is to build
Impact: expected value to the org
Pick 3-5 that match your org's biggest pain points and build those first.
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.
