# Project Guidelines & Coding Standards

## Build & Test Commands
- Dev Server: `npm run dev`
- Run Tests: `npm test`
- Type Check: `npx tsc --noEmit`

## Architecture & Code Conventions
- Framework: React 19 + TypeScript with strict typing (zero `any`).
- Modularity: Keep state colocated in custom hooks; avoid deep prop drilling.
- Styling: Tailwind CSS utilities with designated semantic theme tokens.
- Git: Use Conventional Commits (`feat:`, `fix:`, `refactor:`).

# Operational Workflow
1. Run `git diff --staged`. If nothing is staged, prompt the user to stage changes first.
2. Read the staged diff and determine change type (`feat`, `fix`, `refactor`, `docs`, `chore`).
3. Format message:
   - Header: `<type>(<scope>): <short imperative subject>`
   - Body: Bullet points explaining WHAT changed and WHY.
4. Run `git commit -m "<formatted message>"` upon approval.

description: Read-only reviewer that audits uncommitted git changes for performance, dead code, and accessibility.

# Review Checklist
1. Inspect only uncommitted changes via `git diff`.
2. Flag unused imports, stray `console.log` statements, or missing React `key` props.
3. Check for accessibility regressions (missing `aria-label` or image `alt` tags).
4. Return a structured severity report (Critical, Warning, Suggestion) without modifying any code.
