Can we author our own skills, or does Oxcyon do it?

Ownership and maintenance are different questions. An organization should own its rules, because they encode its policy and its judgement. Whether it has the capacity to keep a growing library coherent is a separate matter, and most do not.

Skills in Centralpoint are console records authored by the people accountable for the underlying policy, with Skill Owner and Review Cadence as fields rather than conventions. The five-tier bucket order gives a non-technical author a clear precedence decision. Oxcyon carries the curation where a client wants it — dependency reconciliation, contradiction resolution, consolidation — without taking ownership of the rules themselves.
