Agent Dispatch

Primary: Code Simplification

Agent({
  description: "Simplify code, eliminate duplication, preserve behavior",
  subagent_type: "code-simplifier",
  prompt: `Simplify the code at: $ARGUMENTS
Follow the task steps and constraints defined in this skill.`
})

Secondary: Refactoring Risk Review

After simplification, dispatch risk assessment:

Agent({
  description: "Review refactoring risk and verify behavior preservation",
  subagent_type: "refactor-reviewer",
  prompt: `Review the refactoring changes just applied.
Check behavior preservation, dependency impact, test coverage, and rollback risk.`
})

Task
