AI Code-Review Assistant for .NET Repos

Challenge

Code reviews were inconsistent across teams; common security and performance issues kept slipping past human reviewers.

Approach

GitHub Action that posts inline review comments — security checks, async/await pitfalls, EF Core anti-patterns, and a prompt-injection scanner for any AI-touching files.

Impact

  • Catches ~40% of bugs before human review across 6 active repos
  • Reduced average PR cycle time from 2.5 days to 1.1 days
  • Surfaced 14 latent SQL-injection and async issues in the first month
