Most teams treat TDD as a way to verify code works. That misses the point entirely. TDD is a design tool — Red-Green-Refactor shapes architecture before implementation, and the failing test is a specification, not a verification step.
A new framework argues that coding agents need external "harnesses" — feedforward guides and feedback sensors — to produce reliable code. We agree. We also built one. Here's how theory maps to a production system, concept by concept.
Vibe coding is productive, inevitable, and here to stay. But without guardrails — prevention, detection, and correction — it creates tech debt at warp speed. The teams that win will be the ones who vibe code with discipline, shipping fast AND shipping safely.
Your team adopted GitHub Copilot, spent $180K on licenses, and expected faster delivery. Instead, lead times got longer, defect rates climbed, and your senior engineers are spending more time reviewing AI-generated code than writing their own. Here's why — and what the fix actually is.
Most teams treat DORA metrics like a dashboard decoration — check them quarterly, nod at the numbers, change nothing. Elite teams use them as a compass that connects delivery performance to engineering decisions. Here's the difference between observing DORA and using DORA.
Most test suites look healthy — high coverage, all green. But run mutation testing and you'll discover that 80-90% of tests would still pass even if you deleted the code they claim to test. Here's what decorative tests are, why they're dangerous, and how to fix them.
