Running Tdd Cycles

Quality score: 70/100 · Category: Engineering · Sub-category: testing

lang:pythonlang:rustlang:ruby

Drive strict red-green-refactor TDD discipline for any code change. Use when a user requests test-driven development, asks to write a failing test first, wants to add a feature one requirement at a time, or invokes a phase like red, green, or refactor. Coordinates failing-test generation, minimal implementation, and refactor-with-safety-net for Python (pytest), JS/TS (Jest/Vitest), Go (testing/T), Java (JUnit), Ruby (RSpec), Rust (cargo test), and Solidity (forge). Enforces test-first ordering, fails-for-the-right-reason verification, and refactor-only-when-green gating. Composes with python-conventions, go-conventions, solidity-conventions, and engineering-philosophy.
