“Coding Coach” — what this page in the network covers. Four modes cover the full learning loop: LEARN — pick a concept and get a Summary / Explanation / real runnable Example / Pitfalls / Next steps lesson tuned to your level (beginner, intermediate, advanced); REVIEW — paste your code, pick a focus (correctness, performance, readability, security, architecture, testing) and get an overall verdict tag ([SEV:OK], [SEV:WARN] or [SEV:BUG]), line-referenced issues and a rewritten fixed version;
DEBUG — paste failing code plus its error message and get a one-sentence root cause, a step-by-step explanation of WHY it failed, the fixed runnable code and general pitfalls to avoid; PRACTICE — pick a topic and get a self-contained exercise with a brief, starter code, three tiered hints and a reference solution you only reveal when you're ready. This listing links straight to the original page, where the content is available in full.
