setup-env-validation

What problem does it solve?

Enforce type-safe environment variable access using t3-env with zod validation. Bans raw process.env.X outside dedicated env files. Use when setting up env validation, t3-env, type-safe environment variables, or banning raw process.env access.

Core Features & Use Cases

• Centralized type-safe environment management with a single src/env.ts and zod schemas.
• PostToolUse hook that blocks direct usage of process.env outside env definitions.
• Clear, repeatable setup steps: install dependencies, create env.ts, wire the hook, and verify.

Quick Start

Install the required packages, create a type-safe env.ts with the provided template, and wire up the hook by placing scripts/env-validation-check.sh and _hook-lib.sh into .claude/hooks and adding the hook to PostToolUse.
