Software is a huge collection of tiny, curated details.

Verifying that they all work can be done in many ways, most of them high-touch - but to me the most effective way is to build a test suite.

And the best way to get a test suite while building is Test Driven Development TDD (with the key trait that you witnessed the tests fail before making them pass, giving you proof they actually prove something about your code) is a high leverage way to ensure details are documented and codified in a way that requires “zero tokens at rest”. If a test fails, something has been un-built; something has regressed. Conversely if all tests pass, your agent burned zero tokens learning that.

The industry will keep inventing other solutions but we have this already, so if you’re in the know, you should use it.

If you’re wondering how to get started you (or your agent) can crib ideas from what I’ve done & open sourced: https://codeleash.dev/docs/tdd-guard/
