API Linting

Optic

Optic catches breaking changes and applies lint rules to OpenAPI specs, generating OpenAPI from real traffic and keeping it accurate with automatic schema testing and patches. The project was archived in January 2026 after Optic Labs was acquired by Atlassian, but the ruleset model remains in active use via sweater-comb and forks.
