Use this skill for systematic diagnosis of complex problems, root cause analysis, and resolution.
Before starting, collect:
| Information | Why it matters |
|---|---|
| Symptoms and error messages | Starting point for investigation |
| Environment (dev/staging/prod) | Determines available tools and access |
| Steps to reproduce | Allows hypothesis validation |
| Timeline of when it started | Correlates with deploys/changes |
| Recent changes | Primary candidates for root cause |
Code review knowledge. Use when reviewing an implementation against requirements, validating code quality, checking edge cases and security, or before opening a PR.
QA and testing knowledge. Use when testing an implementation end-to-end — building a test plan, validating APIs with curl, driving the UI with Playwright, comparing against Figma, and documenting pass/fail with evidence.
Requirements refinement knowledge. Use when turning a vague request into a clear spec, defining API contracts, identifying affected repositories, or capturing scope and edge cases before coding.
AWS infrastructure patterns. Use when working with AWS services, secrets, ECS/EKS, RDS, S3, CloudWatch, or debugging infrastructure issues.
NestJS backend development patterns. Use when developing backend APIs with NestJS, TypeORM/Prisma, and TypeScript.
MySQL database patterns. Use when querying database schema, exploring data, understanding table relationships, or debugging data issues.
