Confirm required deployment keys. Compare the selected environment's binding manifest against the Worker code: vars, resource bindings, service bindings, queues, workflows, durable objects, and secrets are non-inheritable and must be defined in that environment. If using secrets.required, ensure every required name is configured; wrangler deploy and wrangler versions upload validate these names and fail if missing. For local development, use either .dev.vars or .env, not both, and follow environment-specific precedence. Review service targets, routes/domains, resource identifiers and expected provisioning or configuration-file mutations. Do not assume a dry-run exists or treat wrangler types as a general deployment validator.\n\n## Applicability\n\n- Cloudflare Workers Wrangler environments and deployments with environment-specific bindings, variables, secrets, routes, service targets or provisioned resources.\n\n## Procedure\n\n- Select the exact environment and keep inspection and deployment selectors consistent; --env overrides CLOUDFLARE_ENV.\n- Define every binding, variable and secret explicitly for the selected environment; do not rely on top-level binding inheritance.\n- Verify service-binding target names, routes/domains and resource identifiers match the selected environment.\n- Use secrets.required checks as a final guard, not a general dry run.\n- Choose one local secret-file mechanism and keep .dev.vars* and .env* out of Git.\n- Review provisioning and configuration-file write-back side effects before deployment.\n\n## Key findings\n\n- Named environments use --env/-e or CLOUDFLARE_ENV, with the CLI selector taking precedence. (S1, S2)\n- Bindings and environment variables, including vars, resource bindings, services, queues, workflows, durable objects and secrets, are non-inheritable and must be defined per environment. (S1, S2)\n- secrets.required is checked by wrangler deploy and wrangler versions upload; missing required names cause failure. (S2)\n- Local secret files use either .dev.vars or .env with environment-specific precedence and should not be committed. (S1, S2)\n- The cited configuration documentation does not document a general deploy dry-run or comprehensive pre-deployment validator. (S2)\n- Wrangler deployment may provision configured resources and write IDs into the Wrangler configuration.
