solidjs project folder structure

When reviewing or writing code, apply these guidelines:

• Enforce the following folder structure:

src/ components/ pages/ utils/ types/ App.tsx index.tsx

solidjs reactive primitives

When reviewing or writing code, apply these guidelines:

• Use createSignal() for simple reactive state
• Use createEffect() for side effects that depend on reactive state
• Leverage fine-grained reactivity — avoid unnecessary re-renders

Consolidated Skills

This expert skill consolidates 1 individual skills:

• solidjs-expert

Iron Laws

1. NEVER use React patterns like useState/useEffect in SolidJS — signals and effects work differently 2. ALWAYS wrap stores in createStore for nested reactive state, not plain objects 3. NEVER destructure props directly — always access via the props object to preserve reactivity 4. ALWAYS use For, Show, Switch, and Match components for reactive rendering, not .map() 5. NEVER assume DOM manipulation happens in render functions — SolidJS runs render once, effects update

Anti-Patterns

Memory Protocol (MANDATORY)

Before starting:

cat .claude/context/memory/learnings.md

After completing: Record any new patterns or exceptions discovered.

ASSUME INTERRUPTION: Your context may reset. If it's not in memory, it didn't happen.
