Cozy
High-level impact: Cozy helped move SolKraft from descriptive skill metadata toward executable capability contracts—contracts the router can reason about and CI can continuously test. That contribution influenced Contract v1 fixture execution, contribution gates, safer capability selection, and visible regression failures. It came through community discussion rather than a GitHub pull request, and we recognize the impact rather than only the delivery mechanism.
Cozy’s contribution, in his own words:
Nice—keep the skill contract executable: declare inputs, side effects, auth scope, and a few pass/fail fixtures, then run it in CI. That makes capability selection safer and regressions visible.
The skill layer is most useful when each skill declares inputs, side effects, auth scope, and a test contract. Then an agent can select capabilities without treating every tool as an opaque superpower
