80-20-review

Focus code review efforts on high-impact areas by prioritizing critical code paths, security, concurrency, and integration boundaries using blast radius scoring. This approach directs manual review attention toward the most critical 20% of code that causes 80% of issues.

Blast radius scoring in software development is a risk assessment method that determines the depth of review needed based on the potential impact of a change. It helps optimize the development process by weighting review effort toward changes with the highest system-level impact.

Prioritize pull request reviews for critical paths by guiding reviewers through checkpoint schedules and providing checklists for efficient code analysis. This ensures significant risks in data access and integration boundaries are caught early during the development process.

Yes, you can leverage MCP tools for system-level impact assessment before manual review. This allows you to automatically evaluate risk and blast radius, ensuring your manual code review is directed only at the most critical areas.

This code review approach works for large development teams by optimizing the development process through checkpoint reviews at natural lifecycle breakpoints. It scales efficiently by preventing reviewers from getting bogged down in trivial details.

You should avoid using a blast radius approach for code review when evaluating trivial changes or non-critical code paths with minimal integration boundaries. In these cases, a full risk assessment and checkpoint schedule may add unnecessary overhead to the development process.
