Error Diagnostics Error Analysis

When production breaks at 2am, this gives you a structured framework for root cause analysis instead of panicked guessing. It walks you through gathering context, reproducing issues, and validating fixes across distributed systems with proper observability tooling. The skill includes an implementation playbook with debugging checklists and specifically reminds you to redact secrets from diagnostics, which is easy to forget when you're in firefighting mode. Best for post-incident analysis or tracking down recurring errors across multiple services. Won't help much if you're just building new features or don't have access to logs and traces yet.
