Repeating Pre-flight, Post-flight, and per-tool narration in every Custom agent consumes context and allows shared quality rules to drift.
Keep shared lifecycle behavior in deployed Pre-flight and Post-flight Instructions. Keep role workflows, quality gates, tool lists, handoffs, and role-specific Memory Bank extensions in Custom agents.
- Shared behavior has one deployed source.
- Every substantive edit still receives focused validation, final validation, and self-review.
- Independent review scales with risk instead of repeating routine checks.

sections while rejecting duplicate lifecycle blocks.
