c3-change

Orchestrates architectural changes through Agent Teams with ADR-first workflow. This skill should be used when the user asks to: - "add a component", "add feature", "add X to Y", "new component", "create new service" - "add endpoint", "add API", "add middleware", "add handler", "add route" - "change architecture", "modify X", "update component", "refactor X" - "fix X", "fix bug", "fix issue", "implement X", "implement feature" - "remove component", "delete component", "deprecate X" - "provision X", "design the architecture for X", "plan X architecture" - "replace X with Y", "migrate X", "upgrade X" DO NOT use for: "what is X", "how does X work", "explain X" (route to c3-query). DO NOT use for: "add pattern", "create ref", "update ref" (route to c3-ref). DO NOT use for: "audit C3", "validate docs" (route to c3-audit). Requires .c3/ to exist. All changes flow through ADR process with Agent Teams.
