Comprehension debt: when software is created faster than teams understand it
Technical debt is not the only risk created by faster code generation.
Engineering teams may accumulate software that works but is poorly understood by the humans responsible for changing, reviewing, debugging, or operating it.

Code generation can outrun human understanding
Software can be produced faster than the people responsible for it can read and absorb it.
Understanding is concentrated in senior engineers
System knowledge often sits with a few experienced engineers, who become the bottleneck for review and change.
Multi-repository systems amplify the problem
When behavior spans repositories, no one reader sees the whole system.
More documentation is not automatically more comprehension
Documentation helps only when people can find, trust, and absorb it.
Architecture and explicit boundaries become more important
Clear boundaries limit how much any one person must understand to change a part safely.
Verification should preserve evidence
Checks that record what was verified and why leave a trail teams can learn from.
Engineering loops need deliberate reflection
Teams should periodically review what the loop caught, missed, and taught them.
Frequently asked questions
Software that works but is poorly understood by the people responsible for changing, reviewing, debugging, or operating it, because it was created faster than the team could understand it.
Not automatically. Documentation helps only when people can find, trust, and absorb it.
