What happened
A reflection arguing that AI agent harnesses have crossed the 'can it be done' threshold but that software engineering fundamentals—how code fits together, API design, testability—matter more than ever. The author notes open-weight models are closing the capability gap fast on local hardware, and shares a concrete practice: prompting agents with 'develop with red/green TDD' to get testable output, though code seams above that level remain subjective art.
Why it matters
If you're using agentic coding tools, the bottleneck has shifted from 'can the agent write code' to 'can you architect the seams between modules and specify tests.' Try explicitly prompting for TDD and treat the agent as a fast welder, not an architect—your judgment on API boundaries and integration is what keeps the output shippable.
Discussion angle
Compare notes on what prompting strategies actually produce maintainable agent-generated code—does 'red/green TDD' hold up in practice, and where do agent harnesses still fall apart (API design, cross-module integration)?
