+# Environment Variable Gotchas
+
+Common mistakes and how to fix them.
+
+## .env Files Must Be in `inputs`
+
+Turbo does NOT read `.env` files. Your framework (Next.js, Vite, etc.) or `dotenv` loads them. But Turbo needs to know when they change.
+
+**Wrong:**
+
+```json
+{
+  "tasks": {
+    "build": {
+      "env": ["DATABASE_URL"]
+    }
+  }
+}
+```
+
+**Right:**
+
+```json
+{
+  "tasks": {
+    "build": {
+      "env": ["DATABASE_URL"],
+      "inputs": ["$TURBO_DEFAULT$", ".env", ".env.local", ".env.production"]
+    }
+  }
+}
+```
+
+## Strict Mode Filters CI Variables
+
+In strict mode, CI provider variables (GITHUB_TOKEN, GITLAB_CI, etc.) are filtered unless explicitly listed.
+
+**Symptom:** Task fails with "authentication required" or "permission denied" in CI.
+
+**Solution:**
+
+```json
+{
+  "globalPassThroughEnv": ["GITHUB_TOKEN", "GITLAB_CI", "CI"]
+}
+```
+
+## passThroughEnv Doesn't Affect Hash
+
+Variables in `passThroughEnv` are available at runtime but changes WON'T trigger rebuilds.
+
+**Dangerous example:**
+
+```json
+{
+  "tasks": {
+    "build": {
+      "passThroughEnv": ["API_URL"]
+    }
+  }
+}
+```
+
+If `API_URL` changes from staging to production, Turbo may serve a cached build pointing to the wrong API.
+
+**Use passThroughEnv only for:**
+
+- Auth tokens that don't affect output (SENTRY_AUTH_TOKEN)
+- CI metadata (GITHUB_RUN_ID)
+- Variables consumed after build (deploy credentials)
+
+## Runtime-Created Variables Are Invisible
+
+Turbo captures env vars at startup. Variables created during execution aren't seen.
+
+**Won't work:**
+
+```bash
+# In package.json scripts
+"build": "export API_URL=$COMPUTED_VALUE && next build"
+```
+
+**Solution:** Set vars before invoking turbo:
+
+```bash
+API_URL=$COMPUTED_VALUE turbo run build
+```
+
+## Different .env Files for Different Environments
+
+If you use `.env.development` and `.env.production`, both should be in inputs.
+
+```json
+{
+  "tasks": {
+    "build": {
+      "inputs": [
+        "$TURBO_DEFAULT$",
+        ".env",
+        ".env.local",
+        ".env.development",
+        ".env.development.local",
+        ".env.production",
+        ".env.production.local"
+      ]
+    }
+  }
+}
+```
+
+## Complete Next.js Example
+
+```json
+{
+  "$schema": "https://turborepo.dev/schema.v2.json",
+  "globalEnv": ["CI", "NODE_ENV", "VERCEL"],
+  "globalPassThroughEnv": ["GITHUB_TOKEN", "VERCEL_URL"],
+  "tasks": {
+    "build": {
+      "dependsOn": ["^build"],
+      "env": [
+        "DATABASE_URL",
+        "NEXT_PUBLIC_*",
+        "!NEXT_PUBLIC_ANALYTICS_ID"
+      ],
+      "passThroughEnv": ["SENTRY_AUTH_TOKEN"],
+      "inputs": [
+        "$TURBO_DEFAULT$",
+        ".env",
+        ".env.local",
+        ".env.production",
+        ".env.production.local"
+      ],
+      "outputs": [".next/**", "!.next/cache/**"]
+    }
+  }
+}
+```
+
+This config:
+
+- Hashes DATABASE*URL and NEXT_PUBLIC*\* vars (except analytics)
+- Passes through SENTRY_AUTH_TOKEN without hashing
+- Includes all .env file variants in the hash
+- Makes CI tokens available globally
