## Summary Extends the workflow validation layer (introduced in #21422) and adds a new "expected output schema" capability for steps whose output structure is only known at runtime. Some workflow steps (HTTP Request, Code, Logic Function, AI Agent (coming soon), Webhook trigger) don't have a statically known output shape, so downstream steps can't resolve `{{step.x.y}}` variable paths or validate them. This PR lets users declare a **sample/expected output** for those steps, derives an output schema from it, and uses that schema both to power variable resolution and to surface validation issues at build time. ## What's included ### Expected output schema (shared schemas + types) - New `expectedOutputSchemaShape` reused across the HTTP request, code, logic function and AI agent action settings schemas, plus the webhook trigger schema (`expectedOutputSchema` optional loose object). - Mirrored on the server-side action/trigger settings types. ### Output schema computation (server) - `workflow-schema.workspace-service` now computes a step's output schema from the user-declared `expectedOutputSchema` sample (via `getOutputSchemaFromValue`) when no statically computed schema is available. ### Validation layer (server) - `STEP_HAS_NO_VARIABLE_REFERENCE` (warning): flags steps of `VARIABLE_CONSUMING_ACTION_TYPES` (HTTP_REQUEST, CODE, LOGIC_FUNCTION, SEND_EMAIL, record CRUD) that reference no upstream variable. - `LOGIC_FUNCTION_OUTPUT_SCHEMA_MISMATCH` / `AI_AGENT_OUTPUT_SCHEMA_MISMATCH` (warnings): compare the declared output schema against the expected sample using the new shared `getOutputSchemaMismatchIssues` util (missing keys, leaf/object mismatches, type mismatches). - Trigger is now validated alongside steps (trigger type requirements + trigger variable references). - Validation issues no longer return both `suggestions` and `availablePaths` when they are identical (avoids redundant, costly payloads). ### Shared utilities - New `getOutputSchemaMismatchIssues` (+ tests) in `twenty-shared/logic-function`. - Moved `agentResponseSchemaToOutputSchema` from `twenty-front` into `twenty-shared/ai` so it can be reused on both sides. ### Frontend - New `WorkflowExpectedOutputBodyInput` component (JSON sample editor with validation) used by HTTP request, code, logic function and AI agent step editors. - New `resolvePersistedStepOutputSchema` util + `useStepsOutputSchema` update: resolves a step's output schema from `outputSchema`, falling back to `expectedOutputSchema`, with an AI_AGENT default. - HTTP request / code / logic function editors persist `expectedOutputSchema` and derive `outputSchema` from it. - Webhook trigger default settings include `expectedOutputSchema`.

Why Twenty
Twenty gives technical teams the building blocks for a custom CRM that meets complex business needs and quickly adapts as the business evolves. Twenty is the CRM you build, ship, and version like the rest of your stack.

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
