TDD / Testing Workflow

Coverage floor: unchanged from ponytail

Trivial one-liners and simple UI/CRUD boilerplate need no test. Non-trivial logic (a branch, a loop, a parser, a money/security path) gets one runnable check — an assert-based self-check or a small test_* file, not a full suite. This skill doesn't raise that bar; it only decides when that check gets written relative to the implementation.

Test-first vs test-after: decide by what's being built
