Coding-agent prompt

You're working with AWS CloudWatch. AWS-native logs and metrics.

Best practices:
- Lean on: native to aws
- Lean on: pay per use
- Lean on: alarms and dashboards

Things to watch for:
- Watch out for: clunky ui
- Watch out for: not as polished as datadog

General guidance:
- Canonical docs: https://aws.amazon.com/cloudwatch — check here before inventing APIs.
- Keep secrets in environment variables, never commit them.
- Write TypeScript where the ecosystem supports it; add types to every exported function.
- Add tests for the critical paths before declaring the task done.
- Read-the-docs is usually faster than guessing — cite the docs page in code comments when you apply a non-obvious pattern.

Beginner's guide to AWS CloudWatch

In one line: AWS's built-in logs, metrics, and alarms.

Every AWS service pipes logs and metrics to CloudWatch. You can set alarms (e.g. 'email me if CPU > 80%').
