This looks quite promising for some challenges I'm facing. Do you do anything towards having a central source of truth for API contracts? Like a single repo with the specs so that when a change is made everyone can develop against it?

Yep, that's exactly how it goes. Repo contains contracts. Tests pull the latest version from that repo, though you're able to locally override that version to pull in a "unofficial" version.

Spec is created before any dev work begins. It might need changes when the work continues, no worries, the specs are versions and your team can decide on what stable versions are/aren't.
