Catch contract changes before another team discovers them

A change can be correct inside one service and still break another team.

The API & Contract Assurance Agent reviews changes to interfaces, schemas, events, and service contracts so that compatibility risks are visible before merge.

The seams between teams are expensive

Large systems are divided across services, repositories, teams, and ownership boundaries.

The most costly problems often appear at those seams:

  • breaking APIs
  • schema incompatibilities
  • changed event semantics
  • unexpected defaults
  • removed fields
  • version mismatches
  • undocumented behavior changes

What the agent can check

  • REST / RPC interfaces
  • request and response schemas
  • event contracts
  • database-facing contracts
  • compatibility rules
  • versioning conventions
  • deprecation requirements
  • consumer impact
  • migration requirements
  • approved patterns for introducing breaking changes

Check at the right scope

  • During coding

    Warn when the current change modifies an important contract.

  • PR review

    Identify compatibility and consumer-impact risks introduced by the diff.

  • CI

    Compare broader definitions, schemas, generated interfaces, or repository relationships.

Make compatibility rules organization-specific

Different products have different tolerance for breaking changes.

A continuously deployed SaaS system, a public developer platform, and software installed into customer environments may require very different compatibility policies.

AJWAIN.AI co-creates the assurance rules around the customer's actual product and release model.
