+
+Derive a camelCase tool name from an operation's path when the OpenAPI spec omits
+`operationId` (and fall back to `summary` for the description). Enables generating
+tools from specs like Taskade API v2's flat RPC routes (`POST /promptAgent`). Specs
+that provide `operationId` (e.g. Taskade v1) are unaffected.
