Coding-agent prompt

You're working with AWS S3. The original — object storage that scales forever.

Best practices:
- Lean on: industry standard
- Lean on: massive scale
- Lean on: every tool supports it

Things to watch for:
- Watch out for: egress fees
- Watch out for: iam complexity

General guidance:
- Canonical docs: https://aws.amazon.com/s3 — 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 S3

In one line: Amazon's file storage — the de facto standard for uploading files on the web.

S3 (Simple Storage Service) stores files — images, videos, PDFs — in 'buckets'. It scales forever. Nearly every cloud service can read/write to S3.
