# Logging Patterns Skill

**Rule: JSON is the default log format.** Plain text logging is only for local development with `human-logs` profile. Production, CI/CD, and Kubernetes environments must use structured JSON.

## When to Use
- User says "add logging" / "improve logs" / "debug this"
- Analyzing application flow from logs
- Setting up structured logging (JSON)
- Request tracing with correlation IDs
- AI/Claude Code needs to analyze application behavior
