Stop Writing Tests First — Write Formal Specs. Let AI Agent Teams Build Your System.

The Problem Nobody's Talking About Everyone's excited about AI-powered coding. GitHub Copilot autocompletes your functions. Claude and GPT-4 generate entire modules from prompts. But here's the uncomfortable truth: we're still thinking about AI as a single tool , when the real paradigm shift is multiple AI agents working as a team . And that raises a question nobody's answering well: When three AI agents are building three modules in parallel, what prevents them from producing code that doesn't fit together? Natural language specs? Too ambiguous. One agent interprets "the order must be valid" differently from another. Test-driven development? Tests are inductive — they verify specific cases, not the contract between modules. You can have 100% coverage on each module and still watch the system crash at integration. What If Agents Had Blueprints? Think about how a construction project works. You don't hand three subcontractors a paragraph of prose and hope for the best. You give them eng
