Claude Code Project Template v3.4

A production-ready template for Claude Code that turns it into a team of specialized agents with persistent memory, domain-specific skills, and automated workflows. Built for Turborepo + React/Vite + Supabase monorepos.

Open Specs compliant — all 12 skills follow the Agent Skills open standard, making them portable to GitHub Copilot, OpenAI Codex CLI, Cursor, and 20+ other compatible tools.

Why this template?

Claude Code out of the box is a general-purpose assistant. This template transforms it into an opinionated engineering team that:

• Plans before coding — evaluates scope, risks, and affected workspaces before writing a single line
• Follows consistent patterns — every feature, form, query, and test follows documented conventions
• Learns from mistakes — a self-improvement loop captures lessons and prevents repeated errors
• Verifies its own work — runs type-check, lint, and tests before marking anything as done
• Manages context efficiently — uses subagents and progressive disclosure to stay within token limits
