Summary
When you're staring at thousands of log lines trying to figure out why production is broken, this skill automates the grunt work. It detects common log formats (nginx, Spring Boot, JSON, syslog), clusters similar errors so you're not reading the same stack trace 89 times, and looks for timing patterns that suggest root causes. The workflow is solid: it filters by time and severity, extracts response times and status codes, then generates a markdown report with top errors and potential causes. The best part is the causal chain analysis, where it tries to connect a database timeout to the cascade of NPEs that followed. Just watch out for large files since it processes everything in memory.
