Project Rules

These instructions apply to every task performed in this repository.

Purpose

• Treat this file as the project-wide source of truth for repository-specific working rules.
• Read and follow these instructions before making changes in this repo.

Working Style

• Prefer minimal, targeted changes over broad refactors.

selcukcihan

• Make minimum amount of changes. I want to keep the diffs very small because I review them.
• Do not write any tests unless specifically asked.
• Keep the current code style and format, do not deviate.
• Follow the principle of single responsibility by keeping unrelated functions or modules separate.
• Do not make implicit assumptions, try to surface the assumptions so we can review them and guide you if necessary.

Refactoring UI

These are my notes from https://www.refactoringui.com

Starting

• Start with a feature, not a layout. Details comes later, defer choices like color.
• Establish a system (of choices): font size, weight, line height, colors, spacing, shadows etc.
• Refrain from using font weights under 400 for UI work, to de-emphasize some text, use a lighter color or smaller font size instead.
