+# EMCN Components
+
+Import from `@/components/emcn`, never from subpaths (except CSS files).
+
+## CVA vs Direct Styles
+
+**Use CVA when:** 2+ variants (primary/secondary, sm/md/lg)
+
+```tsx
+const buttonVariants = cva('base-classes', {
+  variants: { variant: { default: '...', primary: '...' } }
+})
+export { Button, buttonVariants }
+```
+
+**Use direct className when:** Single consistent style, no variations
+
+```tsx
+function Label({ className, ...props }) {
+  return <Primitive className={cn('style-classes', className)} {...props} />
+}
+```
+
+## Rules
+
+- Use Radix UI primitives for accessibility
+- Export component and variants (if using CVA)
+- TSDoc with usage examples
+- Consistent tokens: `font-medium`, `text-[12px]`, `rounded-[4px]`
+- `transition-colors` for hover states

+# Global Standards
+
+## Logging
+Import `createLogger` from `sim/logger`. Use `logger.info`, `logger.warn`, `logger.error` instead of `console.log`.
+
+## Comments
+Use TSDoc for documentation. No `====` separators. No non-TSDoc comments.
+
+## Styling
+Never update global styles. Keep all styling local to components.
+
+## Package Manager
+Use `bun` and `bunx`, not `npm` and `npx`.

+# Sim App Architecture
+
+## Core Principles
+1. **Single Responsibility**: Each component, hook, store has one clear purpose
+2. **Composition Over Complexity**: Break down complex logic into smaller pieces
+3. **Type Safety First**: TypeScript interfaces for all props, state, return types
+4. **Predictable State**: Zustand for global state, useState for UI-only concerns
+
+## Root-Level Structure
+
+```
+apps/sim/
+├── app/                 # Next.js app router (pages, API routes)
+├── blocks/              # Block definitions and registry
+├── components/          # Shared UI (emcn/, ui/)
+├── executor/            # Workflow execution engine
+├── hooks/               # Shared hooks (queries/, selectors/)
+├── lib/                 # App-wide utilities
+├── providers/           # LLM provider integrations
+├── stores/              # Zustand stores
+├── tools/               # Tool definitions
+└── triggers/            # Trigger definitions
+```
+
+## Feature Organization
+
+Features live under `app/workspace/[workspaceId]/`:
+
+```
+feature/
+├── components/          # Feature components
+├── hooks/               # Feature-scoped hooks
+├── utils/               # Feature-scoped utilities (2+ consumers)
+├── feature.tsx          # Main component
+└── page.tsx             # Next.js page entry
+```
+
+## Naming Conventions
+- **Components**: PascalCase (`WorkflowList`)
+- **Hooks**: `use` prefix (`useWorkflowOperations`)
+- **Files**: kebab-case (`workflow-list.tsx`)
+- **Stores**: `stores/feature/store.ts`
+- **Constants**: SCREAMING_SNAKE_CASE
+- **Interfaces**: PascalCase with suffix (`WorkflowListProps`)
+
+## Utils Rules
+
+- **Never create `utils.ts` for single consumer** - inline it
+- **Create `utils.ts` when** 2+ files need the same helper
+- **Check existing sources** before duplicating (`lib/` has many utilities)
+- **Location**: `lib/` (app-wide) → `feature/utils/` (feature-scoped) → inline (single-use)

+# Component Patterns
+
+## Structure Order
+
+```typescript
+'use client' // Only if using hooks
+
+// Imports (external → internal)
+// Constants at module level
+const CONFIG = { SPACING: 8 } as const
+
+// Props interface
+interface ComponentProps {
+  requiredProp: string
+  optionalProp?: boolean
+}
+
+export function Component({ requiredProp, optionalProp = false }: ComponentProps) {
+  // a. Refs
+  // b. External hooks (useParams, useRouter)
+  // c. Store hooks
+  // d. Custom hooks
+  // e. Local state
+  // f. useMemo
+  // g. useCallback
+  // h. useEffect
+  // i. Return JSX
+}
+```
+
+## Rules
+
+1. `'use client'` only when using React hooks
+2. Always define props interface
+3. Extract constants with `as const`
+4. Semantic HTML (`aside`, `nav`, `article`)
+5. Optional chain callbacks: `onAction?.(id)`
+
+## Component Extraction
+
+**Extract when:** 50+ lines, used in 2+ files, or has own state/logic
+
+**Keep inline when:** < 10 lines, single use, purely presentational

+# Hook Patterns

+## Structure

+```typescript
+interface UseFeatureProps {
+  id: string
+  onSuccess?: (result: Result) => void
+}
+
+export function useFeature({ id, onSuccess }: UseFeatureProps) {
+  // 1. Refs for stable dependencies

+
+  // 2. State
+  const [data, setData] = useState<Data | null>(null)
+  const [isLoading, setIsLoading] = useState(false)
+
+  // 3. Sync refs
+  useEffect(() => {
+    idRef.current = id
+    onSuccessRef.current = onSuccess
+  }, [id, onSuccess])
+
+  // 4. Operations (useCallback with empty deps when using refs)
+  const fetchData = useCallback(async () => {
+    setIsLoading(true)
+    try {
+      const result = await fetch(`/api/${idRef.current}`).then(r => r.json())

+    } finally {
+      setIsLoading(false)
+    }
+  }, [])
+
+  return { data, isLoading, fetchData }
+}
+```
+
+## Rules
+
+1. Single responsibility per hook
+2. Props interface required
+3. Refs for stable callback dependencies
+4. Wrap returned functions in useCallback
+5. Always try/catch async operations
+6. Track loading/error states

+# Import Patterns
+
+## Absolute Imports
+
+**Always use absolute imports.** Never use relative imports.
+
+```typescript
+// ✓ Good
+import { useWorkflowStore } from '@/stores/workflows/store'
+import { Button } from '@/components/ui/button'
+
+// ✗ Bad
+import { useWorkflowStore } from '../../../stores/workflows/store'
+```
+
+## Barrel Exports
+
+Use barrel exports (`index.ts`) when a folder has 3+ exports. Import from barrel, not individual files.
+
+```typescript
+// ✓ Good
+import { Dashboard, Sidebar } from '@/app/workspace/[workspaceId]/logs/components'
+
+// ✗ Bad
+import { Dashboard } from '@/app/workspace/[workspaceId]/logs/components/dashboard/dashboard'
+```
+
+## No Re-exports
+
+Do not re-export from non-barrel files. Import directly from the source.
+
+```typescript
+// ✓ Good - import from where it's declared
+import { CORE_TRIGGER_TYPES } from '@/stores/logs/filters/types'
+
+// ✗ Bad - re-exporting in utils.ts then importing from there
+import { CORE_TRIGGER_TYPES } from '@/app/workspace/.../utils'
+```
+
+## Import Order
+
+1. React/core libraries
+2. External libraries
+3. UI components (`@/components/emcn`, `@/components/ui`)
+4. Utilities (`@/lib/...`)
+5. Stores (`@/stores/...`)
+6. Feature imports
+7. CSS imports
+
+## Type Imports
+
+Use `type` keyword for type-only imports:
+
+```typescript
+import type { WorkflowLog } from '@/stores/logs/types'
+```
