Recovery Feature Scaffold

Generate complete, production-ready features for Steps to Recovery with one command.

Quick Start

# From project root
cd .claude/skills/recovery-feature-scaffold/scripts
node scaffold.js <FeatureName>

# Example - creates a complete gratitude list feature
node scaffold.js GratitudeList

This generates 9 files in under 1 second with all boilerplate wired up.

This generates:

• Database migration (SQLite + Supabase)
• TypeScript types
• Encrypted storage hooks (useFeature.ts)
• CRUD operations with React Query
• List screen + Detail/Edit screen
• Navigation updates
• Test file

Manual Scaffolding (No Script)

Follow this 5-step workflow when script isn't available:

Step 1: Define Types

Create

src/features/<feature>/types.ts

export interface GratitudeItem {
  id: string;
  user_id: string;
  encrypted_content: string;
  category: 'people' | 'things' | 'experiences' | 'other';
  created_at: string;
  updated_at: string;
}

export interface CreateGratitudeInput {
  content: string;
  category: GratitudeItem['category'];
}

export interface UpdateGratitudeInput {
  id: string;
  content?: string;
  category?: GratitudeItem['category'];
}

Step 2: Create Database Migration

SQLite migration (

src/lib/database/migrations/XXX_add_feature.sql

-- SQLite migration
CREATE TABLE IF NOT EXISTS gratitude_items (
  id TEXT PRIMARY KEY,
  user_id TEXT NOT NULL,
  encrypted_content TEXT NOT NULL,
  category TEXT CHECK (category IN ('people', 'things', 'experiences', 'other')),
  created_at INTEGER NOT NULL,
  updated_at INTEGER NOT NULL
);

CREATE INDEX IF NOT EXISTS idx_gratitude_user ON gratitude_items(user_id);
CREATE INDEX IF NOT EXISTS idx_gratitude_created ON gratitude_items(created_at DESC);

Supabase migration (

supabase/migrations/XXX_add_feature.sql

-- Supabase table
CREATE TABLE IF NOT EXISTS public.gratitude_items (
  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
  user_id UUID NOT NULL REFERENCES auth.users(id) ON DELETE CASCADE,
  encrypted_content TEXT NOT NULL,
  category TEXT CHECK (category IN ('people', 'things', 'experiences', 'other')),
  created_at TIMESTAMP WITH TIME ZONE DEFAULT now(),
  updated_at TIMESTAMP WITH TIME ZONE DEFAULT now()
);

-- RLS Policies
ALTER TABLE public.gratitude_items ENABLE ROW LEVEL SECURITY;

CREATE POLICY "Users can only access their own gratitude items"
  ON public.gratitude_items FOR ALL
  USING (auth.uid() = user_id);

-- Trigger for updated_at
CREATE OR REPLACE FUNCTION update_updated_at_column()
RETURNS TRIGGER AS $$
BEGIN
  NEW.updated_at = now();
  RETURN NEW;
END;
$$ language 'plpgsql';

CREATE TRIGGER update_gratitude_items_updated_at
  BEFORE UPDATE ON public.gratitude_items
  FOR EACH ROW EXECUTE FUNCTION update_updated_at_column();

Step 3: Create Encrypted Hooks

src/features/<feature>/hooks/useFeature.ts

import { useQuery, useMutation, useQueryClient } from '@tanstack/react-query';
import { useDatabase } from '../../../contexts/DatabaseContext';
import { encryptContent, decryptContent } from '../../../utils/encryption';
import { generateUUID } from '../../../utils/uuid';
import type { GratitudeItem, CreateGratitudeInput, UpdateGratitudeInput } from '../types';

const FEATURE_KEY = 'gratitude-items';

export function useGratitudeItems() {
  const { db, userId } = useDatabase();

  return useQuery({
    queryKey: [FEATURE_KEY],
    queryFn: async (): Promise<GratitudeItem[]> => {
      if (!db) throw new Error('Database not initialized');

      const items = await db.getAllAsync<GratitudeItem>(
        'SELECT * FROM gratitude_items WHERE user_id = ? ORDER BY created_at DESC',
        userId,
      );

      // Decrypt content for display
      return Promise.all(
        items.map(async (item) => ({
          ...item,
          content: await decryptContent(item.encrypted_content),
        })),
      );
    },
    enabled: !!db && !!userId,
  });
}

export function useCreateGratitude() {
  const { db, userId } = useDatabase();
  const queryClient = useQueryClient();
  const { enqueueSync } = useSyncQueue();

  return useMutation({
    mutationFn: async (input: CreateGratitudeInput): Promise<GratitudeItem> => {
      if (!db) throw new Error('Database not initialized');

      const id = generateUUID();
      const now = Date.now();
      const encrypted = await encryptContent(input.content);

      await db.runAsync(
        `INSERT INTO gratitude_items (id, user_id, encrypted_content, category, created_at, updated_at)
         VALUES (?, ?, ?, ?, ?, ?)`,
        id,
        userId,
        encrypted,
        input.category,
        now,
        now,
      );

      const item: GratitudeItem = {
        id,
        user_id: userId!,
        encrypted_content: encrypted,
        category: input.category,
        created_at: now.toString(),
        updated_at: now.toString(),
      };

      // Queue for sync
      await enqueueSync('gratitude_items', id, 'INSERT', item);

      return item;
    },
    onSuccess: () => {
      queryClient.invalidateQueries({ queryKey: [FEATURE_KEY] });
    },
  });
}

export function useUpdateGratitude() {
  const { db } = useDatabase();
  const queryClient = useQueryClient();
  const { enqueueSync } = useSyncQueue();

  return useMutation({
    mutationFn: async (input: UpdateGratitudeInput): Promise<void> => {
      if (!db) throw new Error('Database not initialized');

      const now = Date.now();
      const updates: string[] = [];
      const values: (string | number)[] = [];

      if (input.content) {
        updates.push('encrypted_content = ?');
        values.push(await encryptContent(input.content));
      }
      if (input.category) {
        updates.push('category = ?');
        values.push(input.category);
      }

      updates.push('updated_at = ?');
      values.push(now);
      values.push(input.id);

      await db.runAsync(`UPDATE gratitude_items SET ${updates.join(', ')} WHERE id = ?`, ...values);

      // Queue for sync
      await enqueueSync('gratitude_items', input.id, 'UPDATE', { id: input.id });
    },
    onSuccess: () => {
      queryClient.invalidateQueries({ queryKey: [FEATURE_KEY] });
    },
  });
}

export function useDeleteGratitude() {
  const { db } = useDatabase();
  const queryClient = useQueryClient();
  const { enqueueSync } = useSyncQueue();

  return useMutation({
    mutationFn: async (id: string): Promise<void> => {
      if (!db) throw new Error('Database not initialized');

      await db.runAsync('DELETE FROM gratitude_items WHERE id = ?', id);

      // Queue for sync
      await enqueueSync('gratitude_items', id, 'DELETE');
    },
    onSuccess: () => {
      queryClient.invalidateQueries({ queryKey: [FEATURE_KEY] });
    },
  });
}

Step 4: Create Screens

src/features/<feature>/screens/FeatureListScreen.tsx

import { useGratitudeItems, useDeleteGratitude } from '../hooks/useGratitude';
import { GratitudeCard } from '../components/GratitudeCard';
import { EmptyState } from '../../../components/EmptyState';
import { Button } from '../../../components/ui/Button';

export function GratitudeListScreen({ navigation }): React.ReactElement {
  const { data: items, isLoading } = useGratitudeItems();
  const deleteMutation = useDeleteGratitude();

  if (isLoading) return <LoadingScreen />;

  return (
    <View className="flex-1 bg-slate-900">
      <FlatList
        data={items}
        keyExtractor={(item) => item.id}
        renderItem={({ item }) => (
          <GratitudeCard
            item={item}
            onPress={() => navigation.navigate('GratitudeDetail', { id: item.id })}
            onDelete={() => deleteMutation.mutate(item.id)}
          />
        )}
        ListEmptyComponent={
          <EmptyState
            icon="Heart"
            title="No Gratitude Items"
            description="Start building your gratitude practice by adding your first item."
          />
        }
      />
      <FloatingActionButton
        onPress={() => navigation.navigate('GratitudeDetail', { id: 'new' })}
      />
    </View>
  );
}

Step 5: Add Navigation

Update

src/navigation/AppNavigator.tsx

import { GratitudeListScreen } from '../features/gratitude-list/screens/GratitudeListScreen';
import { GratitudeDetailScreen } from '../features/gratitude-list/screens/GratitudeDetailScreen';

// Add to stack navigator
<Stack.Screen
  name="GratitudeList"
  component={GratitudeListScreen}
  options={{ title: 'Gratitude' }}
/>
<Stack.Screen
  name="GratitudeDetail"
  component={GratitudeDetailScreen}
  options={{ title: 'Gratitude Item' }}
/>

Update

src/navigation/types.ts

export type RootStackParamList = {
  // ... existing screens
  GratitudeList: undefined;
  GratitudeDetail: { id: string };
};

Feature Templates

Template: Simple List (Gratitude, Affirmations)

Single text field + category/tags.

Template: Journal Entry (Daily Reflection, Step Work)

Rich text content + mood/feelings + date.

Template: Checklist (Step Tasks, Daily Goals)

Multiple items with checkboxes + progress tracking.

Template: Relationship (People, Sponsors)

Contact info + relationship type + notes.

Best Practices

1. Always encrypt sensitive content - Use

   encryptContent()

   before storing
2. Queue all mutations - Call

   enqueueSync()

   after every write
3. Invalidate queries - Use

   queryClient.invalidateQueries()

   after mutations
4. Add indexes - Index

   user_id

   and

   created_at

   columns
5. Test encryption - Verify roundtrip in generated tests

Troubleshooting

Migration number collision

Script auto-detects next migration number. If you have conflicts, manually rename files.

Missing imports

Add to

tsconfig.json

"@/features/*": ["./src/features/*"]

Supabase deploy fails

Ensure you're logged in:

npx supabase login
