How does it reduce PR fatigue?

It encourages 'automating the trivial' by letting tools handle formatting and style, allowing the reviewer to focus exclusively on logic and high-risk integration points.

How does 'blast radius' scoring work?

It evaluates the potential impact of a code change; for example, a middleware change affecting every request has a large blast radius (Critical), while a documentation update has a small one (Low).

What is the 80/20 review principle?

It is based on the Pareto principle, suggesting that 80% of software bugs and production incidents originate from 20% of the code—specifically high-risk areas like security, data access, and concurrency.

Can this skill help detect N+1 queries?

Yes, the skill explicitly focuses on data access patterns and uses checklists to identify where collection loading might cause N+1 performance issues in Entity Framework.

Is this skill specific to .NET?

While the core principles of risk-based review are universal, this implementation is specifically optimized for .NET environments and integrates with Roslyn-based MCP tools.

Collaboration Tools

Prioritizes high-impact code reviews by focusing on the 20% of code—such as security and data access—that causes 80% of production issues.

The 80-20-review skill transforms Claude into a strategic code auditor that prioritizes architectural integrity over cosmetic styling. By utilizing 'blast radius' scoring and a structured checkpoint schedule, it helps developers identify critical paths in .NET applications, such as data access patterns, concurrency risks, and security gaps. It leverages MCP tools to automate trivial checks like formatting and dead code detection, allowing human-like intelligence to focus on complex logic errors, N+1 queries, and resource leaks that automated linters often miss. This approach ensures that review effort is invested where it provides the most significant reduction in production risk.
