Section 1
The premise
Autonomous coding agents have moved from 'demo only' to 'useful for narrow tasks' — but the boundary is sharp and unforgiving.
What AI does well here
- Knock out scoped, well-tested ticket types (renames, version bumps, narrow fixes)
- Drive a long, repetitive migration once a human has scaffolded it
- Generate a first-pass PR a human then completes
- Run unattended on a sandboxed VM
What AI cannot do
- Make architecture decisions or design tradeoffs
- Reliably handle ambiguous requirements without a human in the loop
- Replace the senior engineer who reviews their PRs
