lgtmxp

lgtmxp offers a unique approach to refining code review skills by presenting exercises as realistic pull requests. Each exercise includes a title, description, and diff, designed to simulate real-world development scenarios. Key features of lgtmxp include: identifying subtle bugs such as off-by-one pagination errors, incorrect JWT refresh configurations (e.g., `verify_exp=False`), and runaway agent tool loops. Users flag buggy lines or approve clean diffs, earning experience points (XP) for correct judgments. Missing a bug results in simulated "incidents" like system outages and postmortems on a personal dashboard, providing a tangible consequence to reinforce learning. The platform provides 244 exercises covering various programming languages and frameworks, including Python, React/TypeScript, Go, SQL, and agent-based systems. It's a free, no-signup service, with all progress saved directly in the browser. lgtmxp is ideal for software developers, quality assurance engineers, and technical leads looking to sharpen their code review abilities, particularly in identifying common pitfalls that can arise from advanced development practices. It's a practical training ground for anyone aiming to improve their bug-spotting and code quality assessment skills.
