Implement Plan

Hard rules

Stay on the plan’s required outcome. Discovery/review do not add scope.
Prefer the smallest behavior-preserving change. Skip unnecessary abstractions/tests/safeguards.
Delegate by default when safe. “Small/easy” is not a reason to skip subagents.
Leverage subagents — built-in, extensions/plugins, or skills. Follow use-subagents policy; use native subagents, extensions / plugins, or other skills
Main agent owns: tracker, integration, dispositions, acceptance, user comms, cleanup.
Child handoffs = evidence, never acceptance. Inspect diffs; rerun checks.
Findings / decomplex recs never auto-create work — disposition first.
Material doubt, scope/risk choices, or stuck review loops → ask user.
Never fake Complete.
