Turn ChatGPT and Claude into your senior engineer. This is a 20-prompt coding system covering the tasks that eat a developer's week: (1–2) debugging — the Bug Hunter that finds root causes from your error, and the Rubber Duck that asks diagnostic questions, (3) staff-level code review with severity-ranked findings, (4–6) refactoring, docstrings, and README generation, (7–9) unit tests, edge-case hunting, and SQL tuning, (10–12) regex building, error translation, and legacy-code decoding, (13–16) naming, performance profiling, commit messages, and security audits, (17–20) architecture explainers, migration plans, boilerplate scaffolding, and interview drills. Every prompt ships with tool settings (model picks, temperature, what to paste), a negative prompt that blocks truncated code and invented APIs, and a variation — 40+ workflows from one pack. It kills the two biggest AI-coding pains: vague answers from vague input (the paste-it-right method fixes that) and answers written for the wrong version (versions are baked into every prompt). Works with ChatGPT-4o, Claude Sonnet, or any modern LLM; includes the 7-day action plan and the never-paste-secrets rule.
