A general-purpose Agent Skill that helps backend developers quickly troubleshoot API issues — call chains, error points, and optimization suggestions, with a complete report from one command. Locating an API during production incidents or test failures usually takes 10–30 minutes of searching through code. This skill turns the process into two commands, aiming to produce a report in 60–90 seconds.
