BreakCheck

.breakcheck.yml

Schema paths, baseline branch, fail rules

Schema paths

Point BreakCheck at your OpenAPI file. Example:

openapi:
  path: openapi.yaml

Baseline branch

Checks compare the PR schema against the baseline branch (usually the default branch). Platform owns the parser.

Fail rules

A breaking change fails the Check. Additive changes stay green. See What counts as breaking.
