Contract Verification Across Repos: Catching Breaking Changes at AI Velocity

In modern production systems, a single feature often spans multiple repositories, with backend services defining APIs, clients consuming them, and separate repositories generating SDKs or deploying artifacts. This complexity necessitates maintaining compatibility across rapidly changing systems, where AI coding assistants expedite changes but also alter the software risk landscape. Subtle mismatches can arise when changes appear correct in isolation but fail at the boundaries of interconnected repositories, highlighting the importance of shared contracts between producers and consumers. Qodo addresses these challenges by treating these boundaries as first-class objects, automatically discovering and verifying cross-repository relationships and contracts. For instance, in a payment platform spread across three repositories, Qodo analyzes technical signals to identify and verify connections, like those between a payment service, SDK, and checkout application, ensuring that changes do not break established contracts. This capability allows teams to catch potential contract failures early in the review process, providing actionable insights that trace the dependency through several repositories, enhancing the code review process by ensuring compatibility before changes are merged.
