    "incantation": "When a Worker repository needs environment types for AI Search bindings, add `ai_search_namespaces` and/or `ai_search` to its Wrangler config, then run `wrangler types` to generate binding types. By default, Wrangler includes bindings from all configured environments.",
    "examples": [
      "wrangler types",
      "{\"ai_search_namespaces\":[{\"binding\":\"<ENV_BINDING>\",\"namespace\":\"<NAMESPACE>\"}],\"ai_search\":[{\"binding\":\"<ENV_BINDING>\",\"instance_name\":\"<INSTANCE_NAME>\"}]}"

    "gotchas": [
      "Version: 4.80.0",
      "PATH: Optional output path for generated types; defaults to `./worker-configuration.d.ts` and must end in `.d.ts`.",
      "--env: Restricts generated bindings to the named environment; without it, bindings from all configured environments are included.",
      "ai_search_namespaces[].binding (required): Environment variable name for the namespace binding.",
      "ai_search_namespaces[].namespace (required): Namespace to bind; Wrangler creates it on deploy if it does not exist.",
      "ai_search_namespaces[].remote: Set to `true` for local development with `wrangler dev`.",
      "ai_search[].binding (required): Environment variable name for the instance binding.",
      "ai_search[].instance_name (required): AI Search instance name; it must exist in the default namespace at deploy time.",
      "ai_search[].remote: Set to `true` for local development with `wrangler dev`.",
      "Supports both simple and per-environment modes."
