Test-Driven Agent Development
Write the tests first, let the agent implement until they pass — why TDD works even better with AI agents.
Here's a powerful idea: instead of describing what you want in English (which is ambiguous) or in a detailed plan (which is better but still imprecise), describe what you want in tests (which are exact, executable, and verifiable).
Write the tests first. Then tell the agent: "Make these tests pass."
This is Test-Driven Development (TDD), and it turns out to be a near-perfect fit for AI agents. The tests serve as an unambiguous specification, the agent implements against them, and you have automatic verification that the implementation is correct.
Why TDD + Agents Is a Perfect Match
Traditional TDD requires discipline. You have to resist the urge to write the implementation first and come back to tests later (which often means never). Many developers find TDD tedious — writi
