# Pino Ultra-Fast Low-Overhead JSON Logger for Node.js

Configures Pino logger: structuring child loggers with context bindings (reqId, tenantId), log levels (debug, info, error), custom serializers, redaction of sensitive keys (password, authorization), and pino-pretty for development.

## When to Invoke
Invoke this skill whenever you need to:
- configure pino logger
- redact sensitive fields pino
- async destination pino

## Execution SOP & Rules
1. Initialize logger: const logger = pino({ level: 'info', redact: ['req.headers.authorization', '*.password'] }).
2. For extreme performance: use pino.destination({ sync: false }) to avoid blocking event loop on disk I/O.
3. Create child logger per request: const reqLogger = logger.child({ reqId: req.id }).
4. Pipe through pino-pretty in development only; keep raw newline-delimited JSON in production.

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
