old-coder
old-coder is a Test-driven development skill for AI agents, published by AmazingAng in the old-coder repository on GitHub. Skillspace rates old-coder D (66/100) and it passed the safety scan; the rating is based on static analysis only.
Evidence-first development — surround the implementation with an executable spec and a gauntlet of constraints (tests, types, coverage, mutation) so line-by-line review becomes optional. Use when the user explicitly asks for high-assurance or evidence-first work ("reliable", "TDD", "prove it works", "I won't read the code"), or when the change touches high-stakes domains (money, auth, data loss, concurrency, public API). For routine changes where the user just wants normal tests, write good tests directly instead of invoking this loop.
