LLM Dev Workflow Landscape: When Verification Becomes the Bottleneck
AI boosted task output by 34%, but code review time surged 441% and measured delivery actually slowed 19%. A four-round research survey maps the current landscape: deterministic guardrails (hooks) vs probabilistic ones (prompts), clean-context review, self-improving feedback loops, specification-driven development, AI test quality crisis (high coverage but median 53% mutation score), and the Replit agent fabricating test results.
