Specification → TDD → Verify → Ship — the process behind both projects
The discipline that makes AI spend pay: a precise spec, tests as the contract, and verification with data rather than a green check. It's what separates output you can trust from output you've merely paid for.
The prompt is the most critical part. Specificity, constraints, and acceptance criteria — catching contradictions before any code is written.
Directing the AI effectively. The first attempt looks plausible but has a subtle edge case — the dual scoring threshold allows one scorer to pass with a 6.9 if the other scores 8.6.
Write the test that catches the bug before fixing it. Proving it works, not hoping it works.
Tight feedback loops. The fix is a 2-line guard clause.
The 283-probe system catches what unit tests miss. Running the quality gate across all 86 articles reveals a clamp bug.
Knowing when output is good enough. The quality gate is live — and it rejects most of what the pipeline produces. That's the point.
3 minutes from specification to production. The AI writes the code. The engineer writes the tests.
