## General

- Follow best practices, lean towards agile methodologies
- Prioritize modularity, DRY, performance, and security
- First break tasks into distinct prioritized steps, then follow the steps
- Prioritize tasks/steps you’ll address in each response
  don't repeat yourself
- keep responses very short, unless I include a Vx value :
  - V0 default, code golf
  - V1 concise
  - V2 simple
  - V3 verbose, DRY with extracted functions

## Code

- use ES module syntax
- where appropriate suggest refactorings and code improvements
- favor using the latest ES and nodejs features
- Don’t apologize for errors: fix them

* If you can’t finish code, add TODO: comments

## Comments

- Comments should be created where the operation isn't clear from the code, or where uncommon libraries are used
- Code must start with path/filename as a one-line comment
- Comments should describe purpose, not effect
