0 to 20, Agents Are Lost. Agents hallucinate and cannot navigate. Every task needs a human driving.
21 to 40, Agents Struggle. Heavy supervision; you correct most of what they produce.
41 to 60, Agents Survive. Useful but slow, with frequent corrections.
61 to 75, Agents Can Work Here. Productive on routine tasks on their own.
76 to 85, Agents Are Productive. Independent on most tasks; supervision becomes review, not hand-holding.
86 to 100, Agents Thrive. A force multiplier across the codebase.
Most codebases that have never been tuned for agents land between 40 and 65. That is not a failing grade. It means the foundations are there and the gaps are fixable, which is exactly what the roadmap is for.
