What it does

Setting up evlog in a new or existing project (any supported framework)
Reviewing code for logging best practices
Converting console.log statements to structured logging
Improving error handling with better context
Configuring log draining, sampling, or enrichment
Designing wide events → references/wide-events.md
Improving errors → references/structured-errors.md

Requirements & configuration

Access the logger via c.get('log') in handlers. No useLogger() — use c.get('log') and pass it down explicitly, or use Express/Fastify/Elysia if you need useLogger() across async boundaries.
| Manual token tracking in onFinish | ai.wrap() — middleware captures automatically |
