Tech-Dev Skill (Development Stage)

This skill handles MCP integration and third-party service configuration during development.

v1 edit scope (hard limit)

For first pass, only modify:

• Project directory files (if template was applied)
• .env.local / .env.development / .env.production
• Configuration files from MCP snippets
• .create-together/state.json - update development status
• .create-together/context.json - add dev_config

Do not:

• Modify any files in templates/built-in/*
• Change package.json dependencies (unless MCP requires)
• Modify routing or layout structure (unless MCP requires)
• Introduce features beyond selected MCPs

Dev workflow (required)

• Before starting: Read state.json and context.json to understand project state
• Before starting: Ensure required MCP snippets are available
• Before starting (ShipAny + Supabase): Verify DB_SCHEMA is set and matches the target schema
• Before starting (ShipAny + Supabase): Hard requirement ensure ShipAny tables exist in DB_SCHEMA (use src/config/db/schema.ts)
• Before starting (ShipAny + Supabase): If user-only actions are needed, explicitly instruct the user (e.g., provide DATABASE_URL, register account for admin)
• After finishing:

- Clear Next.js cache: rm -rf .next - Run npm run build to validate integration - Run MCP-specific validation commands (see checklist) - Update state.json to phase: "iterate-check"

Execution order

1. Understand development needs: references/00-dev-workflow.md
2. Review MCP layer: references/01-mcp-layer.md
3. Select and configure MCPs:

- Auth: references/02-mcp/auth.md - Stripe: references/02-mcp/stripe.md - Analytics: references/02-mcp/analytics.md - Supabase: references/02-mcp/supabase.md - Vercel: references/02-mcp/vercel.md

1. If using ShipAny template + Supabase Postgres (MANDATORY):

- Follow dev/10-supabase-shipany.md - Ensure ShipAny tables exist in DB_SCHEMA (especially config and RBAC tables) - Prefer Supabase MCP to create schema/tables if migrations are not run - If Vercel MCP is configured, update env vars there as well - Remind user to register an admin account before role assignment - If legacy tables exist (e.g. users/prompts/templates), migrate or clean up to avoid confusion

1. Validation checklist: references/03-checklist.md
