Hi, I would like to know if there is a real way to validate an entire conversation inside a Dify workflow, not just single responses or isolated messages.
Here is my use case:
I have an LLM that generates a JSON structure containing a full story (for example, a pirate-themed narrative using tags like [voice:name]). After the model generates this story, I need to validate the entire output against specific rules, such as confirming that the story starts with pirates, that Captain Barbanegra Rojo wants to steal the king’s gold, that the king’s daughter appears in the story, that the JSON format is correct, and that all voice tags are properly used.
I need this validation to happen automatically inside the workflow right after the story is generated. The goal is not to validate a single message, but the complete generated content — or even the entire conversation if necessary.
I would like to know if Dify currently offers any official mechanism to validate a full JSON output or multi-turn content, or if there is a recommended way to implement structured validation over the results produced by the LLM.
In short, I need Dify to take the complete JSON output from a previous step, analyze it, check whether it follows all the narrative rules I define, and then return something like “valid / invalid” along with a list of errors.
Is this possible with the current Dify tools, or is support for full conversation validation planned for future updates?
Here’s an example:
The story has to start with some pirates.

“content”: “[voice:narrador]: In the heart of the stormy seas, a fearsome pirate crew gathered on the deck of the ship known as The Tempest. [voice:antonio]: Ahoy, me hearties! They call me Blackbeard, captain of this cursed vessel, and I lead you into the depths of adventure! [voice:santiago]: I am Santiago, the cunning first mate, always ready to navigate through treacherous waters. [voice:sofia]: And I, Sofia, the fierce gunner, shall defend our ship with unmatched valor! [voice:jaime]: The treasure awaits, and I, Jaime, the swift hands of the crew, will be the first to claim it! [voice:veronica]: Beware! For the sea is full of dangers, and I, Veronica, the wise sage, can foresee the perils that lie ahead. [voice:leo]: But fear not, for luck is on our side. I, Leo, the charmer, can win over any foe we encounter. [voice:hernan]: Let them come! I am Hernan, the brutish fighter, and I shall crush any who dare oppose us! [voice:melina]: Together we sail, united in our quest for glory and gold! [voice:carla]: But remember, even the fiercest pirates face their reckoning. Let us tread carefully, for the sea remembers! [voice:matias]: And I shall make sure we remain stealthy, for I am Matias, the silent shadow of the crew. [voice:rodrigo]: What say ye, captain? Shall we set sail into the storm? [voice:antonio]: Aye! The winds favor us! Hoist the sails and let the adventure begin!”

I have a cunning plan to steal the gold from the evil king! [voice:antonio]: Speak, Santiago! What do you have in mind? [voice:sofia]: The king’s treasure is heavily guarded, we must be clever! [voice:jaime]: I can slip past their defenses, as silent as the night! [voice:veronica]: And I can sense the king’s movements, guiding us through the shadows. [voice:leo]: With my charm, I can distract the guards while you make your move! [voice:hernan]: And I will be ready to fight if things go awry! [voice:melina]: Together, we can achieve the impossible! [voice:carla]: But we must tread lightly; the king’s fury knows no bounds.

Prepare the ship, for we sail at dawn!”

“content”: “[voice:narrador]: As the days passed, Santiago found himself drawn to a figure that would change his fate. [voice:santiago]: I cannot help but admire her beauty from afar, the king’s daughter. [voice:sofia]: What madness is this, Santiago? She is the daughter of our enemy! [voice:jaime]: Love can be a dangerous game, my friend. [voice:veronica]: But perhaps she holds the key to our plan. [voice:leo]: If you win her heart, we may gain an ally within the castle! [voice:hernan]: Or a traitor among us! [voice:melina]: Be cautious, Santiago. The heart can lead us astray. [voice:carla]: Love and war are often intertwined; tread lightly! [voice:matias]: I can help you, Santiago. Stealth is my specialty, and I’ll ensure you meet her without alerting the guards. [voice:rodrigo]: Aye, but remember, if her father discovers this, it could mean doom for us all. [voice:santiago]: I know the risks, but I must try. For love is a treasure worth fighting for!”

Here I want to use another model to validate everything.
