Fetch Supabase Example Skill

Purpose: Retrieve official Supabase integration patterns from core-supabase repository

When to Use

Agents should invoke this skill when:

• Implementing Repository layer with Supabase
• Need RPC function usage patterns
• Require parameter structure examples
• During v0.4.x CODE phase of implementation

Quick Start

Schema Verification (우선순위)

# 1. Supabase MCP (실시간 스키마) - 우선
mcp__supabase__list_tables()
mcp__supabase__get_table_schema()

# 2. database.types.ts (로컬 타입)
@src/lib/supabase/database.types.ts

# 3. core-supabase (참조 구현)
gh api repos/semicolon-devteam/core-supabase/...

Fetch from core-supabase

# List available test examples
gh api repos/semicolon-devteam/core-supabase/contents/document/test

# Fetch specific domain example
gh api repos/semicolon-devteam/core-supabase/contents/document/test/posts/createPost.ts \
  --jq '.content' | base64 -d

Usage

// Agent invokes this skill
skill: fetchSupabaseExample("posts", "read");

// Returns: RPC function, parameters, type assertion pattern

Critical Rules

1. Always use RPC functions: Never write raw SQL in Repository
2. Follow parameter naming: Use p_ prefix for all RPC parameters
3. Type assertion pattern: Always as unknown as Type
4. Error handling: Always check error before using data
5. Optional parameters: Use null as unknown as undefined

Available Domains

• posts - Post CRUD operations
• comments - Comment operations
• users - User profile operations
• activities - User activity tracking

Dependencies

• GitHub CLI (gh) with authentication
• Access to semicolon-devteam/core-supabase repository
